Method Detail

getInsertedRowsCount

public 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

public 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

public 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

public 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

public 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

public boolean isValid()
Check if this statement is valid.

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