Method Detail

getBindVariableSetsForMutatedRows

public Collection getBindVariableSetsForMutatedRows(ParsedStatement parsedStatement,
                                                    BindVariableSet bindVariableSet,
                                                    TableMetadata tableMetadata,
                                                    Connection connection)

For all the rows affected by parsedStatement, return a BindVariableSet instance that contains the current values for all thr columns affected by parsedStatement.

Parameters:

parsedStatement - a SQL statement that is about to execute on the database

bindVariableSet - the bind variables that will be used to populate parsedStatement

tableMetadata - description of the columns in the table being affected by parsedStatement

connection - a real JDBC connection to the database (so that current values can be read)

Returns:
