我正在创建一个查询,该查询将选择表中的所有数据.查询将根据我将传递给存储过程的变量选择到表中.
I am creating a query that will select all data on the table. The query will select to the table base on the variable that I will pass on the stored procedure.
在我的例子中.如果我执行 example_sp table1
,它将在 table1
中选择.同样的事情,如果我使用 example_table table2
,它应该选择 table2
.
Here in my example. If I execute example_sp table1
it will select in table1
. Same thing if I use example_table table2
, it should selecttable2
.
ALTER PROCEDURE example_sp
@type varchar(10), -- value will be `table1` or `table2`
AS
BEGIN
SELECT * FROM @type
END
Gordon 建议的版本略有不同......
A slightly different version of what Gordon has suggested.....
ALTER PROCEDURE example_sp
@TableName SYSNAME --<-- Use appropriate data type for sql server objects
AS
BEGIN
SET NOCOUNT ON;
Declare @Sql NVARCHAR(MAX);
SET @Sql = N' SELECT * FROM ' + QUOTENAME(@TableName)
Exec sp_executesql @Sql
END
