Method Detail

addColumnSetQuery

public void addColumnSetQuery(ColumnSet pSet, TableReference pTableReference)

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=?.

addConstraint

public void addConstraint(Map pMap, Constraint pConstraint)

Clones the given Constraint, mapping the column references from the given constraint to the values in the given map.

Parameters: pMap A Map with the constraints pConstraint table references as keys. The values are table references of the current constraints statement. pConstraint The constraint being cloned.

addJoin

public void addJoin(ForeignKey pKey, TableReference pReferencingTable, TableReference pReferencedTable)

Creates a JOIN condition matching the given foreign key. In other words, if the foreign key consists of the columns A and B referencing the columns X and Y, then the following will be added: A=X AND B=Y.

Parameters: pKey The foreign key being matched. pReferencingTable A reference to the table returned by the foreign keys ForeignKey method. pReferencedTable A reference to the table returned by the foreign keys getReferencedTable method.

addJoin

public void addJoin(TableReference pReferencingTable, ColumnSet pReferencingColumnSet, TableReference pReferencedTable, ColumnSet pReferencedColumnSet)

Creates a JOIN condition matching the given column reference. In other words, if the referencing ColumnSet contains the columns A and B, and the referenced column set contains ColumnSet, X and Y, then the following will be added: A=X AND B=Y.
