MultiStatement
public class MultiStatement implements Statement(Code)
MultiStatement is a wrapper class for a callable Statement obtained by a MultiConnection object. The sole function of this class is to log the sql statement passed to it using the MultiConnection that called it - all calls are then passed to the Statement object passed to the constructor.

Field Detail
parent
MultiConnection parent(Code)
The connection that created this statement.




Constructor Detail
MultiStatement
MultiStatement(MultiConnection parent, Statement s)(Code)




Method Detail
addBatch
public void addBatch(String sql) throws SQLException(Code)



cancel
public void cancel() throws SQLException(Code)



checkAfterException
protected Statement checkAfterException() throws SQLException(Code)
Tries to fix the parent connection, if it proves to be broken. It is supposed to be broken if the query "SELECT 1 FROM WHERE 1 = 0" does yield an exception. This method is meant to be called in the catch after trying to exceute a statement. A new Statement object if a new Connection was successfully obtained. Or null, if 'SELECT 1' did succeed.
throws:
  SQLException - if SELECT 1 did fail an no new Connection could be obtained.
