Method Detail

getInMemoryOffset

protected int getInMemoryOffset(int queryOffset)

Description copied from class: BaseSQLAction

Returns a value of the offset that will be used to rewind the ResultSet within the SQL action before reading the result rows. The default implementation returns 'queryOffset' argument. If the adapter supports setting offset at the SQL level, this method must be overridden to return zero to suppress manual offset.
