Right-click the Tables option and select New Table.

The Create Table dialog displays. Locate the Schema drop-down list.
From the Schema drop-down list, select the owner of the table.
In the Name text field, type a name for the table.

You can now define the columns for your table. Locate the Columns region.

Define the columns of your table

To define the columns of your table, locate the Columns table. For each of the columns that you want to define:

In the PK column, click in the column if you want to define this column as a primary key. You need to have a primary key if you want to create an index on your table.
In the Name column, type a column name. For more information on supported column names, see "Basic names" in the Oracle TimesTen In-Memory Database SQL Reference.
In the Data Type column, select a data type for your column. For more information on data types, see "Data Types" in the Oracle TimesTen In-Memory Database SQL Reference.
In the Size column, select a size for your column based on your the data type that you selected.
If you want this column to be NOT NULL, select the Not Null check box.
If you want this column to have a default value, type a value in the Default column.
If you want to define this column as INLINE, select the Inline check box. By default, variable-length columns whose declared column length is > 128 bytes are stored out of line. Variable-length columns whose declared column length is <= 128 bytes are stored inline.

You have successfully defined a column for your table.

To add another column, click the + button that is located in the top right corner of the Columns table. Then, repeat steps 1-7 to define each column.

To remove a column, select the column that you want to remove and click the - sign that is located in the top right corner of the Columns table.

To copy a column, select the column that you want to copy and click the Copy Column button that is located in the top right corner of the Columns table.

Once you have defined all of the columns for your table:

If you defined a primary key for your table, create an index for your table. See Create an index for your table for more information.
If you did not define a primary key on your table, set constraints for your table. See Set constraints for your table for more information.

Create an index for your table

To define an index for your table, you need to have defined a primary key for your table. To define an index on your table:

Select an index type from the Index Type options. For more information on index types, see "CREATE TABLE" in the Oracle TimesTen In-Memory Database SQL Reference.
If you selected a hash index, type a RowPages parameter in the Page size(Rows) text field.
Compute this value by dividing the number of expected rows in your table by 256. For example, if your table has 256,000 rows, specify 1000 for the value of RowPages (256000/256=1000).

You have successfully defined an index on your table. You are now ready to define constraints for your table.

Set constraints for your table

Select the Constraints tab to work with constraints for your table.

If you have defined a primary key or compound primary key in the columns tab, you see this primary key constraint in the Constraints tab.

You can set these types of constraints:

Primary key constraint: If you have not defined a primary key for your table in the Columns tab, click the + button located in the top right corner of the Constraints region and then select New Primary Key Constraint.

If you have already defined a primary key, the New Primary Key Constraint option is not available. However, you are able to edit the definition of your primary key in the constraints region.

In the Constraints table you can:
- Edit the name of your primary key by editing the name column of the Primary Key row.
- Select columns to be part of your primary key definition by double clicking the column name in the Available Columns list.
- Remove columns from your primary key definition by double clicking the column name in the Selected Columns list.
- Remove a primary key constraint by selecting the primary key constraint that you want to remove, and then clicking the x sign that is located in the top right corner of the Constraints region.
Foreign key constraint: To define a foreign key for your table:
1. Click the + button located in the top right corner of the Constraints region and then select New Foreign Key Constraint.
2. In the Constraints table, specify the name of your foreign key. You can edit the name of a foreign key by editing the name column of the Foreign Key row in the Constraints table.
  
  Locate the Referenced Constraint region.
3. From the Schema drop-down list, select the schema name of the table that you want to reference. Alternatively, you can type the schema name instead of selecting it from the drop-down list.
4. From the Table drop-down list, select the table name that you want to reference. Alternatively, you can type the table name instead of selecting it from the drop-down list.
5. From the Constraint drop-down list, select a primary key constraint name that you want to reference. Alternatively, you can type the primary key constraint name instead of selecting it from the drop-down list.
6. From the On Delete drop-down list, select an on delete option.
You have successfully defined a foreign key constraint.
- To add another foreign key constraint, the + button located in the top right corner of the Constraints region and then select New Foreign Key Constraint. Then, repeat steps 1-6 to define each foreign key constraint.
- To remove a foreign key constraint, select the foreign key constraint that you want to remove and click the x sign that is located in the top right corner of the Constraints region.

Set the distribution method for your table

This tab is only available when working with a TimesTen Scaleout table.

To define the distribution method for your table:

Select the Distribution tab.
From the Distribution method drop-down list, select a distribution method for your table:
- Distribute by Hash: Distribution scheme that distributes data based on the hash of the primary key or a set of user-specified columns. For more information, see "Hash" in the Oracle TimesTen In-Memory Database Scaleout User's Guide.
  
  When you decide how to distribute your table with the hash distribution scheme, consider the following:
  - If the table has a primary key and you do not specify a distribution, column, TimesTen Scaleout distributes the data based on the hash of the primary key.
  - If the table does not have a primary key or you do not specify a distribution column, TimesTen Scaleout distributes the data based on the hash of a hidden column that TimesTen Scaleout adds for this purpose.
  - If you specify a distribution column, TimesTen Scaleout distributes the data based on the hash of the distribution column. You can specify multiple distribution columns.
  To specify distribution columns for your table:
  - To select columns to be part of your distribution column, double click the column name in the Available Columns list.
  - To remove columns from your distribution column, double click the column name in the Selected Columns list.
- Distribute by Reference: Distribution scheme that distributes the data of a child table based on the location of the corresponding parent row of a foreign key constraint. Your table needs at least one foreign key to be able to use this distribution scheme. For more information, see "Reference" in the Oracle TimesTen In-Memory Database Scaleout User's Guide.
  
  Ensure that you have defined a foreign key to use the distribute by reference distribution scheme. To distribute your table with this distribution scheme:
  
  From the Foreign Key drop-down list, select the foreign key to distribute the data of your table.
- Distribute by Duplicate: Distribution scheme that distributes full identical copies of the table's data to all the elements of a database. For more information, see "Duplicate" in the Oracle TimesTen In-Memory Database Scaleout User's Guide.
  
  When you select the distribute by duplicate distribution scheme, you do not need to specify any additional fields in the Distribution tab of the Create Table dialog.
You are now ready to review the DDL of your CREATE TABLE statement. See Review the DDL of the CREATE TABLE statement for more information.

Review the DDL of the CREATE TABLE statement

You can review the DDL of your CREATE TABLE statement.

Select the DDL tab.

Note:

To save the DDL statement in a .sql file, click the Save button.
Once you have reviewed the DDL statement, click OK.

You have successfully created a table.

Edit a table

You can alter a table that is already created. When you alter an existing table, you cannot perform these actions:

Change the schema name.
Change the table name.
Change the index.
Change the distribution scheme of a table that contains data. This only applies to TimesTen Scaleout tables.

To edit a table, ensure that you are on the main SQL Developer page and that your connection is expanded:

Expand the Tables option, right-click the table name, and then select Edit.

The Edit Table dialog displays. The Edit Table dialog is the same as the Create Table dialog, except that not all options can be edited. You can edit all of the options except for those that are mentioned above. See Create a table for more information on how to use the Create Table dialog.

Review the distribution of data for a TimesTen Scaleout table

You can view distribution statistics for your table. This feature is only available for TimesTen Scaleout tables. Distribution statistics enable you to see how your data is distributed between the data instances of your grid.

To view the distribution statics for a table, ensure that you are on the main SQL Developer page and that your connection is expanded:

Expand the Tables option and double-click the table name.

A table view displays. Locate the Distribution tab.
Click the Distribution tab from the table view.

The Distribution tab displays.

Figure 4-1 Distribution tab

Description of "Figure 4-1 Distribution tab"

The Distribution tab contains these regions:

Note:

The contents of each region can vary depending on the distribution scheme of the table.

Row distribution chart

This chart can show either a column or pie chart of the row count of your table on each of your elements. Use the drop-down list in this region to switch between the column and pie chart for your table.

The pie chart enables you to view a pie chart for the row count of each element of your data space groups. Use the drop-down list in this region to switch between data space groups. The pie chart is not available when your table uses a duplicate distribution scheme.

If one of your elements is down or unavailable, the corresponding column chart for that element becomes unavailable. Also, the pie chart for the data space group of the element becomes unavailable.
Distribution scheme table

This table shows you information about the distribution scheme that your table uses.
- Distribute by hash distribution scheme - This table shows the columns that TimesTen Scaleout uses to create a hash in order to distribute the rows of your table.
- Distribute by reference distribution scheme - This table shows the foreign key relationship that TimesTen Scaleout uses to distribute the rows of your table.
- Duplicate distribution scheme - This table doesn't show any information because this distribution scheme has the same information on every element.
Row distribution table

This table shows the row count of your table on each of your elements. You can also see information about the data space group, replica set, element ID, instance name, and distribution percentage for each of the elements. If you use the duplicate distribution scheme, the distribution percentage column is not available.

If one of your elements is down or unavailable, the row count and distribution percentage columns for that element are marked as unavailable.

If the table is distributed by hash or reference, the distribution tab will display a summary row including totals for row count and distribution. This summary is only accessible when the table is sorted by data space group and will be hidden if sorted on a different column. If needed, this information is always available in the "Summary" tab next to "Row Distribution".

If the table is distributed by hash or reference, this table displays summary rows with total row count and distribution percentage for each data space group. However, this is only available if the row distribution table is sorted by data space groups. If you use a different sort order, you can click the Summary tab to see these summary rows.
Summary table

This table shows the row count and distribution percentage for each data space group.

Alter the aging properties of a table

You can add an aging policy to or drop an aging policy from a regular table or a cache table. You can also change the aging state for a table's existing aging policy, or change the lifetime and cycle for a table's existing time-based aging policy. An aging policy is only supported on TimesTen tables.

The following sections describes these aging policy operations:

Adding an aging policy to a table

To add an aging policy to a regular table or a cache table, under the Tables node, right-click the name of the table to add an aging policy to and select Aging, then select Add Usage-based to add an LRU aging policy. To add a time-based aging policy select Aging, then select Add Time-based. An aging policy can be added to a cache table only if it is the root table of a cache group.

If you are unable to find the table that you are looking for, see Locating a TimesTen database object.

To add an LRU aging policy to the table, in the Prompts tab of the Add Usage-based dialog box, specify an aging state by choosing either On or Off in the Usage-based aging field. The default aging state is on. Click Apply to add the LRU aging policy to the table.

The TimesTen database memory usage thresholds determine when data starts and stops being deleted from the table. The default memory usage threshold that determines when data starts being deleted from the table is 90%. The default memory usage threshold that determines when data stops being deleted from the table is 80%. The default LRU aging cycle is 1 minute. For information about how to change these thresholds and the LRU aging cycle, see Specifying an aging policy.

An LRU aging policy can be added to any regular table, and only to cache tables in an AWT, SWT or user managed cache group that does not have automatic refresh defined.

To add a time-based aging policy to the table, in the Prompts tab of the Add time-based dialog box, select the column name from Column to store the timestamp value indicating when each row was added or most recently updated.

In the Life-time field, indicate the length of time in which data that has not been updated is to be kept in the table by specifying a numeric value followed by a unit of minutes, hours or days in the drop-down menu.

In the Cycle field, indicate the frequency at which data is to be aged out of the table by specifying a numeric value followed by a unit of minutes, hours or days. The default time-based aging cycle is 5 minutes.

Specify an aging state by choosing either On or Off in the Time-based aging field. The default aging state is on. Then click Apply to add the time-based aging policy to the table.

A time-based aging policy can only be added to a table that contains a non-nullable DATE or TIMESTAMP column.

Dropping an aging policy from a table

To drop an existing aging policy from a regular table or a cache table, under the Tables node, right-click the name of the table to drop an aging policy from and select Aging, then select Drop.

If you are unable to find the table that you are looking for, see Locating a TimesTen database object.

Click Apply to drop the aging policy from the table.

Changing the aging state of a table's aging policy

To change the aging state of a regular table's or cache table's existing aging policy, under the Tables node, right-click the name of the table to change the aging state of and select Aging, then select Change State On/Off.

If you are unable to find the table that you are looking for, see Locating a TimesTen database object.

To create a sequence, ensure that you are on the main SQL Developer page and that your TimesTen or TimesTen Scaleout connection is expanded.

Right-click the Sequences option and select New Sequence.

The Create Sequence dialog displays. Locate the Schema drop-down list.
From the Schema drop-down list, select the owner of the sequence.
In the Name text field, type a name for the sequence.
In the Start With text field, specify the first sequence number to be generated.

Use this field to start an ascending sequence at a value that is greater than the minimum value or to start a descending sequence at a value less than the maximum.
In the Increment text field, specify the incremental value between consecutive numbers.

This value can be either a positive or negative integer. It cannot be 0. If the value is positive, it is an ascending sequence. If the value is negative, it is descending. The default value is 1.
In the Min Value text field, specify the minimum value for an ascending sequence, or the final value for a descending sequence.

This value must be less than or equal to the value that you specified in the Start With field. The default minimum value is 1.
In the Max Value text field, specify the largest possible value for an ascending sequence, or the starting value for a descending sequence.

This value must be greater than or equal to the value that you specified in the Start With field. The default maximum value is (2⁶³) -1, which is the maximum value of the BIGINT data type.
If you want to cache the numbers from this sequence, select the Cache option from the Cache drop-down list. If not, select the No Cache option.
If you selected the Cache option from the Cache drop-down list, in the Cache Value text field, specify the range of numbers that are cached.

When a restart occurs, unused cached numbers are lost. If you specify a cache value of 1, then each use of the sequence results in an update to the database. Larger cache values result in fewer changes to the database and less overhead. The default value is 20.
From the Cycle drop-down list, select one of these options:
- Cycle: The sequence number generator continues to generate numbers after it reaches the maximum or minimum value.
- No Cycle: The sequence number generator stops generating numbers when the maximum or minimum value is reached.
By default, sequences do not cycle. Once the number reaches the maximum value in the ascending sequence, the sequence wraps around and generates numbers from its minimum value. For a descending sequence, when the minimum value is reached, the sequence number wraps around, beginning from the maximum value.
In the Batch value text field, define the range of unique sequence values that are stored at each element of the grid. The default value is 10 million. This option is only available for TimesTen Scaleout databases.

Locate the OK button.

Note:

If you want to review the DDL statement that TimesTen or TimesTen Scaleout uses to create your sequence, click the DDL tab.
