可以证明:在存储过程级指定 WITH RECOMPILE 强制重编译 和SQL语句级指定的OPTION(RECOMPILE)强制重编译,相同条件下生成的执行计划是不一样的。 为什么WITH RECOMPILE强制重编译 和 OPTION(RECOMPILE)强制重编译得到的执行计划是不一样的? WITH RECOMPILE强制重编译是每次运行存储过程,都根据当前的参数情况做一次重编译...

User-defined functions are another example of T-SQL statements. User-defined functions take input parameters, perform an action and return the results to the call. Restore a database with T-SQL. Another example is a trigger, which is a stored T-SQL script that runs when a statement other ...
When creating a natively compiled stored procedure, rather than using a cursor, use set-based logic or a WHILE loop. Feature Non-constant parameter defaults When using default values with parameters on natively compiled stored procedures, the values must be constants. Remove any wildcards from the...
For parameters, use either the value or @parameter_name=value. Note Make sure that you validate the structure of the string command before running it with the EXECUTE command. Syntax The following example shows the SQL Server syntax that runs a stored procedure or fun...
