Package oracle.pg.rdbms.pgql

Interface PgqlResultSet

  • All Superinterfaces:
    java.lang.AutoCloseable, java.lang.Iterable<oracle.pgql.lang.ResultAccess>, oracle.pgql.lang.ResultAccess, oracle.pgql.lang.ResultSet<oracle.pgql.lang.ResultAccess>
    All Known Implementing Classes:
    oracle.pg.rdbms.pgql.PgqlResultSetImpl, PgViewResultSet
    public interface PgqlResultSet
extends oracle.pgql.lang.ResultSet<oracle.pgql.lang.ResultAccess>
    This interface provides a ResultSet for a PGQL query execution. It extends the oracle.pgql.lang.ResultSet interface with methods to get meta data for the result set and also to determine the data type for a particular value.

      • getValueType

        int getValueType​(int elementIdx)
          throws oracle.pgql.lang.PgqlException
        Returns the type of value for the given element. The returned values correspond to values in the T column of the PG relational schema.
        Parameters:
        elementIdx - element index
        Returns:
        the type of value
        Throws:
        oracle.pgql.lang.PgqlException - when an error occurs while retrieving the value type

      • getValueType

        int getValueType​(java.lang.String elementName)
          throws oracle.pgql.lang.PgqlException
        Returns the type of value for the given element. The returned values correspond to values in the T column of the PG relational schema.
        Parameters:
        elementName - element name
        Returns:
        the type of value
        Throws:
        oracle.pgql.lang.PgqlException - when an error occurs while retrieving the value type

      • close

        void close()
    throws oracle.pgql.lang.PgqlException
        Closes the underlying JDBC ResultSet and Statement.
        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface oracle.pgql.lang.ResultSet<oracle.pgql.lang.ResultAccess>
        Throws:
        oracle.pgql.lang.PgqlException

      • print

        default PgqlResultSet print​(long numResults)
        Prints numResults results to System.out. If numResults is larger than the number of available results, only the number of available results are printed.
        Parameters:
        numResults - number of results
        Returns:
        PgqlResultSet

      • print

        default PgqlResultSet print​(long numResults,
                            int from)
        Prints numResults results from fromth result to System.out.
        Parameters:
        numResults - number of results
        from - first result to be printed (start counting from 0)
        Returns:
        PgqlResultSet

      • print

        PgqlResultSet print​(java.io.PrintStream printStream,
                    long numResults,
                    int from)
        Same as print(long, int) except that this method prints content to printStream.
        Parameters:
        printStream - stream to which results are printed
        numResults - number of results
        from - first result to be printed (start counting from 0)
        Returns:
        PgqlResultSet
