Produces a set of WHERE Clauses to use in the DELETE queries which have filters spanning multiple entities. It produces one clause if it finds the deleteTable on the PK side and then stops and it produces n clauses if it finds deleteTable on the FK side of n relations in relationsToWalk. If the deleteTable is on the PK side, it produces a clause: deleteTableAlias.PKField1 = deleteTable.PKField1 AND... (for each field in the PK 1 clause) If the deleteTable is on the FK side, it produces deleteTableAlias.Field1 = relatedEntityTable.Field1 AND ... clauses for each relation the table of the persistence info is in.

Produces a set of WHERE Clauses to use in the UPDATE queries which have filters spanning multiple entities. It produces one clause if it finds the updateTable on the PK side and then stops and it produces n clauses if it finds updateTable on the FK side of n relations in relationsToWalk. If the updateTable is on the PK side, it produces a clause: updatedTableAlias.PKField1 = updateTable.PKField1 AND... (for each field in the PK 1 clause) If the updateTable is on the FK side, it produces updatedTableAlias.Field1 = relatedEntityTable.Field1 AND ... clauses for each relation the table of the persistence info is in.

Creates a retrieval query for the tvfcall specified.

Creates the TVF function name fragment list. By default it will create 'FunctionName(parameterList)'. Override this method if the DQE requires a different strategy to call a TVF, e.g. wrapping it.

Creates a new Update Query object which is ready to use. Only 'changed' EntityFields are included in the update query. Primary Key fields are never updated.

Creates a new Update Query object which is ready to use. Only 'changed' EntityFieldCore fields are included in the update query.

Determines if duplicates will occur.

Determines if field alias is required.

Determines the object alias to use for select list field.

Determines the target alias to use for a single target FROM clause.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Gets the correct field type, based on the type and lenght specified in the specified persistenceInfo

Serves as the default hash function.

Gets the new name for the catalog, given the current name. If the current name is not found in the list of catalog name overwrites, the current name is returned. This routine works on the catalog names specified in the config file.

Gets the new name of the sequence passed in. Default implementation overwrites schema name with a new name if the name has been defined for overwriting. Works on the PerCallSchemaNameOverwrites set.

Gets the new name of the stored procedure passed in. Overwrites schema and catalog name with a new name if these names have been defined for overwriting. This routine works on the PerCallCatalogNameOverwrites and PerCallSchemaNameOverwrites names specified on this instance

Gets the new name for the schema, given the current name. If the current name is not found in the list of schema name overwrites, the current name is returned. This routine works on the schema names specified in the config file.

Gets the new name of the sequence passed in. Default implementation overwrites schema name with a new name if the name has been defined for overwriting.

Gets the new name of the stored procedure passed in. Overwrites schema and catalog name with a new name if these names have been defined for overwriting. This routine works on the catalog and schema names specified in the config file.

Gets the fragment to use in a projection for a literal NULL. By default this is 'NULL', but some databases need extra processing around NULL. Do to so, override this method.

Gets the table valued function name to use. By default it creates an object name from the elements specified like a table name.

Gets the Type of the current instance.

Handles the emit of 'DISTINCT' into the query text and returns true if distinct was emitted or false if not.

Makes the parameters anonymous in the passed in query. An anonymous parameter is '?', not '@foo'. It walks all parameters and replaces the names of these parameters with "?" in the query text

Makes the parameters anonymous in the passed in query. An anonymous parameter is '?', not '@foo'. It walks all parameters and replaces the names of these parameters with "?" in the query text

Creates a shallow copy of the current Object.

Prepares, if necessary, the passed in query object for a batch update query. Use this method to e.g. create an output parameter which collects the number of rows affected.

Reassembles the fragments specified, with separting '.'. If a fragment is empty, it's skipped

Re-assembles the stored procedure name from the fragments specified

Resets the creator object with a new one. Only used by DAO objects which keep a Dynamic Query Engine object alive.

Returns a string that represents the current object.

Updates the SourceAlias in the predicates in updateFilter to the alias updatedTableAlias if the predicate targets the entity name specified.

Wraps the command in the query specified in a paging query and adds necessary parameters to the command.

Wraps the passed in query if necessary. By default it returns the toWrap string without doing any processing.
