Sql server 调用EXEC（）生成错误：找不到存储过程

我需要对一个表调用delete，该表的名称只有在运行时才为人所知

我有一个存储过程，它使用tablename和criteria动态地生成delete语句，然后将该字符串作为参数传递给EXEC函数——显然，所有这些都在事务中

当我运行存储过程时，我得到一个错误-找不到存储过程-引用我动态制定并发送给EXEC的语句

这是我的密码：

DECLARE @dynTab AS varchar(50), @dynDelete AS varchar(255)
    DECLARE @crsr CURSOR
    SET @crsr = CURSOR FAST_FORWARD
    FOR
    SELECT dyn_tablename FROM dyn_tab WHERE dyn_doc_type_id IN (SELECT doc_id FROM tree_tab WHERE id = @id) AND dyn_tablecreated = 1

OPEN @crsr
FETCH NEXT FROM @crsr
INTO @dynTab

WHILE @@FETCH_STATUS = 0 AND @@ERROR = 0
    BEGIN
        SET @dynDelete  = 'DELETE FROM ' + @dynTab + ' WHERE id = ' + @id 
        EXEC @dynDelete

        FETCH NEXT FROM @crsr
        INTO @dynTab
    END

            CLOSE @crsr
        DEALLOCATE @crsr 
        IF @@ERROR <> 0
        BEGIN
            ROLLBACK TRAN
            return 0
        END

以下是错误：

找不到存储过程“从id=1111的myTable中删除”

不带括号的EXEC尝试调用过程

试一试EXEC@dynDelete你需要写 EXEC@dynDelete

使用EXEC或EXECUTE执行Sql查询，如下所示：

SET @dynDelete  = 'DELETE FROM ' + @dynTab + ' WHERE id = ' + @id 
EXEC(@dynDelete)

或

---

如果使用EXEC，则从SqlDataSource中删除DeleteCommandType

SET @dynDelete  = 'DELETE FROM ' + @dynTab + ' WHERE id = ' + @id 
EXECUTE(@dynDelete)
