sp_executesql批处理中的本地游标或变量对调用sp_executesql的批处理是不可见的。对数据库上下文所做的更改只在sp_executesql语句结束前有效。如果只更改了语句中的参数值,则sp_executesql可用来代替存储过程多次执行 Transact-SQL 语句。因为 Transact-SQL 语句本身保持不变,仅参数值发生变化,所以 SQL Server 查询优...

仔细看了,段1 @return_value 返回整个查询结果,可是为什么 自定义的是int 型的,去掉了直接赋参执行存储过程还是不出数据。 段二EXEC 直接执行存储过程就返回整个结果了。 找到了以前写的单独的存储过程返回table 的如段3,看到里面结束时候也没有select,但是为什么直接在工具里execute就能出结果, 一时没有想明白是...
sp_executesql can be used instead of stored procedures to execute a Transact-SQL statement many times when the change in parameter values to the statement is the only variation. Because the Transact-SQL statement itself remains constant and only the parameter values change, the SQL Server...
