Description copied from interface: BindVariableResolver

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

Specified by:

getBindVariableSetsForMutatedRows in interface BindVariableResolver

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:

a collection of BindVariableSet instances, one for each row affected by parsedStatement. Each BindVariableSet will contain the current values for the columns being affected in each row.
