您将使用sp_executesql
。绑定变量如下所示:@var1
。
从下面的链接,与标准的Northwind数据库查询示例:
DECLARE @IntVariable int;
DECLARE @SQLString nvarchar(500);
DECLARE @ParmDefinition nvarchar(500);
/* Build the SQL string one time.*/
SET @SQLString =
N'SELECT BusinessEntityID, NationalIDNumber, JobTitle, LoginID
FROM AdventureWorks2008R2.HumanResources.Employee
WHERE BusinessEntityID = @BusinessEntityID';
SET @ParmDefinition = N'@BusinessEntityID tinyint';
/* Execute the string with the first parameter value. */
SET @IntVariable = 197;
EXECUTE sp_executesql @SQLString, @ParmDefinition,
@BusinessEntityID = @IntVariable;
/* Execute the same string with the second parameter value. */
SET @IntVariable = 109;
EXECUTE sp_executesql @SQLString, @ParmDefinition,
@BusinessEntityID = @IntVariable;
