execute

public boolean execute(java.lang.String sql)
                throws java.sql.SQLException

Executes an SQL statement and indicates the form of the first result. You can then use getResultSet() or getUpdateCount() to retrieve the result.

Specified by:

execute in interface java.sql.Statement

Parameters:

sql - An SQL statement.

Returns:

True if the result is a ResultSet; False if it is an integer

Throws:

java.sql.SQLException - This exception is thrown if a ShareNetException is detected

getMoreResults

public boolean getMoreResults()
                       throws java.sql.SQLException

Moves to a Statement's next result. This method always returns False because SAS software does not support multiple ResultSets. The method also implicitly closes any current ResultSet obtained with getResultSet().

Specified by:

getMoreResults in interface java.sql.Statement

Returns:

True if the next result is a ResultSet; False if it is an integer.

Throws:

java.sql.SQLException - This exception is required by the interface, but it is never thrown.

See Also:

execute(java.lang.String)

setFetchDirection

public void setFetchDirection(int direction)
                       throws java.sql.SQLException

JDBC 2.0 Gives a hint as to the direction in which the rows in the result set created by this statement will be processed. Currently, the rows of the resultset will be processed only in the forward direction.

Specified by:

setFetchDirection in interface java.sql.Statement

Parameters:

direction - An integer indicating the direction in which the rows of the result set will be processed. Currently supports only FETCH_FORWARD.

Throws:

java.sql.SQLException - This exception is thrown if the fetch direction is not FETCH_FORWARD.

getFetchDirection

public int getFetchDirection()
                      throws java.sql.SQLException

JDBC 2.0 Gets the fetch direction for the result set created by this statement. The rows of the resultset will be processed only in forward direction.

Specified by:

getFetchDirection in interface java.sql.Statement

Returns:

An integer value indicating FETCH_FORWARD.

Throws:

java.sql.SQLException - This exception is required by the interface but it is never thrown.

setFetchSize

public void setFetchSize(int rows)
                  throws java.sql.SQLException

JDBC 2.0 Sets the number of rows to be fetched. Note 1: The integer fetchSize is casted to a short and so fetch size value might get truncated to 2 bytes. Note 2: The performance hint is ignored if you are connected to a V6 SAS/SHARE server. Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified only affects result sets created using this statement. If the value specified is zero, then the hint is ignored.

Specified by:

setFetchSize in interface java.sql.Statement

Parameters:

rows - The number of rows to fetch.

Throws:

java.sql.SQLException - This exception is thrown if a database-access error occurs, or the condition 0 <= rows <= this.getMaxRows() is not satisfied.
