DynamicQueryEngineBaseCreateSingleTargetUpdateDQUsingCorrelatedSubQuery Method

Creates a new Update Query object which is ready to use. Only 'changed' EntityFieldCore are included in the update query. Primary Key fields are never updated. Uses a correlated subquery for filtering

Namespace:  SD.LLBLGen.Pro.ORMSupportClasses
Assembly:  SD.LLBLGen.Pro.ORMSupportClasses (in SD.LLBLGen.Pro.ORMSupportClasses.dll) Version: 5.4.0.0 (5.4.0)
Syntax
Copy
protected void CreateSingleTargetUpdateDQUsingCorrelatedSubQuery(
	IEntityFieldCore[] fields,
	IFieldPersistenceInfo[] fieldsPersistenceInfo,
	IActionQuery query,
	IPredicate updateFilter,
	IRelationCollection relationsToWalk,
	bool addSetClauseParametersLast
)

Parameters

fields
Type: SD.LLBLGen.Pro.ORMSupportClassesIEntityFieldCore
Array of EntityFieldCore objects to use to build the insert query
fieldsPersistenceInfo
Type: SD.LLBLGen.Pro.ORMSupportClassesIFieldPersistenceInfo
Array of IFieldPersistenceInfo objects to use to build the update query
query
Type: SD.LLBLGen.Pro.ORMSupportClassesIActionQuery
The query object to fill.
updateFilter
Type: SD.LLBLGen.Pro.ORMSupportClassesIPredicate
A complete IPredicate implementing object which contains the filter for the rows to update
relationsToWalk
Type: SD.LLBLGen.Pro.ORMSupportClassesIRelationCollection
list of EntityRelation objects, which will be used to formulate a FROM clause with INNER JOINs.
addSetClauseParametersLast
Type: SystemBoolean
if set to it will add the update set clause parameters as the last set of parameters to the command object. Some ado.net providers need this (OleDb / Jet for example)
