addColumnSetQuery

public void addColumnSetQuery(ColumnSet pSet,
                              TableReference pTableReference)
Description copied from interface: CombinedConstraint

Adds a check for the columns of the given column set. For example, if the column set consists of the columns A and B, then the following will be added: A=? AND B=?.

Specified by:
addJoin in interface CombinedConstraint
