在SSIS中,可以使用动态T-SQL语句来执行各种数据库操作,包括创建、修改和查询表。 动态T-SQL语句是指在运行时根据参数或变量的值来构建和执行SQL语句。使用参数作为表名的动态T-SQL语句可以实现根据不同的参数值来操作不同的表,提高代码的灵活性和重用性。 以下是一个示例的动态T-SQL语句,使用参数作为表名: 代码...
如果表变量是在 EXEC 语句或sp_executesql存储过程外部创建的,则不能使用 EXEC 语句或sp_executesql存储过程来运行引用表变量的动态 SQL Server 查询。 由于表变量只能在其本地范围内引用,因此 EXEC 语句和sp_executesql存储过程将超出表变量的范围。 但是,可以创建表变量并在 EXEC 语句或sp_executesql存储过程内执...
SQL Server requires you to specify explicitly the list of values in the IN clause to rotate to result columns. You can't use a static query and have SQL Server figure out all distinct values in OrderYear. To achieve this, you have to use dynamic execution to construct the query string ...
