SD.LLBLGen.Pro.DQE.SqlServer.NET20

DynamicQueryEngine for SqlServer.

Flag to signal the DQE to generate SET ARITHABORT ON statements prior to INSERT, DELETE and UPDATE Queries. Keep this flag to false in normal usage, but set it to true if you need to write into a table which is part of an indexed view. It will not affect normal inserts/updates that much, leaving it on is not harmful. Please consult SqlServer's Books online for more details on SET ARITHABORT ON. After each statement the setting is turned off if it has been turned on prior to that statement.

Setting this flag is a global change.

Flag to signal the DQE to tell the SqlServerSpecificCreator to create WITH NOLOCK hints on table references in select queries for FROM clauses. WITH NOLOCK is not recommended though in high volume databases with a lot of rows, it can be a lot of blocking can occur because SqlServer forces readers to block writers and vice versa. Please consult the SqlServer's Book online for more information about this hint and also the downsides for using it. The setting is global and for all select queries. Default is false and it should only be set to true in those situations in which no other option is available.

Setting this flag is a global change.

Compatibility level used by the DQE. Default is SqlServer2000. To utilize SqlServer 2005 specific features, set this parameter to SqlServer2005, either through a setting in the .config file of your application or by setting this parameter once in your application. Compatibility level influences the query generated for paging, sequence name (@@IDENTITY/SCOPE_IDENTITY()), and usage of newsequenceid() in inserts.

Setting this parameter will overrule a similar setting in the .config file
