Method Detail

getInsertedRowsCount

int getInsertedRowsCount()
                         throws java.sql.SQLException
Get number of inserted rows. You can call this method multiple times, it does not affect the JDBC result number.

Returns:
number of inserted rows or -1 if current result is result set.
Throws:
java.sql.SQLException - if database error occurs.

getUpdatedRowsCount

int getUpdatedRowsCount()
                        throws java.sql.SQLException
Get number of updated rows. You can call this method multiple times, it does not affect the JDBC result number.

Returns:
number of updated rows or -1 if current result is result set.
Throws:
java.sql.SQLException - if database error occurs.

getDeletedRowsCount

int getDeletedRowsCount()
                        throws java.sql.SQLException
Get number of deleted rows. You can call this method multiple times, it does not affect the JDBC result number.

Returns:
number of deleted rows or -1 if current result is result set.
Throws:
java.sql.SQLException - if database error occurs.

hasOpenResultSet

boolean hasOpenResultSet()
Check if this statement has open result set. Note, this method works correctly if auto-commit is disabled. In auto-commit mode it will always return false because from the statement's point of view result set is not open (in auto-commit mode complete result set is fetched and cached in wrapping object before returning from the Statement.getResultSet() method).

Returns:
true if there's already open result set associated with this statement, otherwise false.

getCurrentResultSet

java.sql.ResultSet getCurrentResultSet()
                                       throws java.sql.SQLException
Get current result set. Behaviour of this method is similar to the behavior of the Statement.getResultSet(), except that this method can be called as much as you like.

Returns:
instance of ResultSet representing current result set or null if it is not available.
Throws:
java.sql.SQLException - if database access error happened.

isValid

boolean isValid()
Check if this statement is valid.

Returns:
true if statement is valid and can be used to execute SQL.

getLastExecutionPlan

java.lang.String getLastExecutionPlan()
                                      throws java.sql.SQLException
Get execution plan for the last executed statement. Unlike the FirebirdPreparedStatement.getExecutionPlan(), this method can be called only after executing a query or update statement.

Returns:
execution plan returned by the server.
Throws:
java.sql.SQLException - if no statement was executed before calling this method, statement is not valid, or there was an error when obtaining the execution plan.

isClosed

boolean isClosed()
                 throws java.sql.SQLException
Retrieves whether this Statement object has been closed. A Statement is closed if the method close has been called on it, or if it is automatically closed.

Provided here for compatibility with Java 5

Specified by:
isClosed in interface java.sql.Statement
Returns:
true if this Statement object is closed; false if it is still open
Throws:
java.sql.SQLException - if a database access error occurs
