ICS.SelectTo

Performs a simple query from a table.

Syntax

public IList 
SelectTo(String from,
         String what,
         String where,
         String orderby,
         int limit,
         String listname,
         boolean bCache,
         StringBuffer errstr)

Parameters

from

Table to query. The table must exist.

what

Comma-separated list of table columns to return. The string * means all columns.

where

Comma-separated list of column names which must have associated variables. The value of the variable is used to match the contents of that column. The variables in the comma-separated list must exist; if they do not, ICS.SelectTo() returns error -106. When you specify a date/time field in where, Sites uses the cc.datepicture property to convert the supplied datetime to the proper format.

orderby

Comma-separated list of columns used to sort results. The
ascending/descending order is database-dependent.

limit

The maximum number of rows returned from the query. To indicate no limit, set this value to -1.

listname

The name of the list created. The list can be referenced using this name from an XML tag or by using the getList method. If no listname is specified, the system will generate the name of the list.

bCache

true to cache the results; false otherwise. Regardless of the value of bCache, the existing cache will be used to generate the return value, but new resultsets will not be cached.

errstr

For return values; may contain error information.

Description

The SelectTo method performs a simple query from a table. The results are stored in a list.

Returns

IList object that contains the results. An empty result set returns a value of null.

Error Numbers

If IList is null, use GetErrno to find the error.

Example

// If forumId isn't set, list all forums
if (forumId != null) 
  {
    ics.SetVar(Msg.forumid, forumId);
    mList = ics.SelectTo(Msg.forumXTable, Msg.allFields, 
                     (forumId == null) ? null : Msg.forumid, null, 
                     Msg.noLimit, null, Msg.cacheResults, errstr);
  }
if (mList != null)
  {
    mColNames = Utilities.words(forumCols, Msg.comma);
    mCols = mColNames.size();
  }
