'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...

See the example "Running multiple queries in a single transaction" in the Examples section later in this article. If consistent execution plans are important in your paging solution, consider using theOPTIMIZE FORquery hint for theOFFSETandFETCHparameters. SeeSpecify expressions for OFFSET and FETCH ...
