'DISABLE_PARAMETER_SNIFFING' Instructs Query Optimizer to use average data distribution while compiling a query with one or more parameters. This instruction makes the query plan independent on the parameter value that was first used when the query was compiled. This hint name is equiva...
The following table lists the system catalog views that you can use to return metadata about user-defined functions. 展开表 System viewDescription sys.sql_modules See example E in the Examples section. sys.assembly_modules Displays information about CLR user-defined functions. sys.parameters Display...
See the Examples section that follows in this topic. INSERT queries that use SELECT with ORDER BY to populate rows guarantees how identity values are computed but not the order in which the rows are inserted. In Parallel Data Warehouse, the ORDER BY clause is invalid in VIEWS, CREATE TABLE ...
SpecifyingFORCESEEKwith parameters limits the number of plans that can be considered by the Query Optimizer more than when specifyingFORCESEEKwithout parameters. This might cause a "Plan cannot be generated" error to occur in more cas...
