例如,以下查询可以获取名为"my_stored_procedure"的存储过程的参数数据类型信息: 代码语言:sql 复制 SELECT name, system_type_name, user_type_id FROM sys.parameters p INNER JOIN sys.types t ON p.system_type_id = t.system_type_id WHERE object_id = OBJECT_ID('my_stored_procedure') 代码语言:t...
因为每次传过来的参数即表名是不固定的,所以需要一个字符串变量拿到参数里的值再拼接成最终的sql(相对于翻译一下),再去数据库里执行。 CREATE PROCEDURE [dbo].[usp_getColumnsBycolumn]( @tabname VARCHAR(100)) AS DECLARE @sql VARCHAR(8000) DECLARE @STRING VARCHAR(500) BEGIN SELECT @sql= ISNULL(@sq...
Building the final t-sql code or final stored procedure call by adding the parameter values into the statement is easy but is not a good way of using sp_ExecuteSQL SQL procedure. The preferred method for using sp_executesql with parameters should be using the@paramsargument which takes place...
SqlCommandcmd=newSqlCommand(CustOrdersOrders,conn);//创建SqlCommand对象 conn.CommandType=CommandType.StoredProcedure; SqlParameterCustID=newSqlParameter("@CustomerID",SqlDbType.Char,5); CustID.value=“ALFKI”;//对输入参数赋值 cmd.Parameters.Add(CustID); SqlParameterCount=newSqlParameter("@num",SqlDbType...
document, and I might be interested in exactly those new parameters. So my task is to extract the nth member of docPath according to some conditions—and this is a quite trivial task, if you write a script, stored procedure, or UDF, using T–SQL functions. But, if you want to get ...
_sqlCmd.CommandType=CommandType.StoredProcedure; //先清楚参数 _sqlCmd.Parameters.Clear(); _sqlCmd.Parameters.AddRange(Parameters); if(sqlconn.State!=ConnectionState.Open) { sqlconn.Open(); } intret=-1; try { ret=_sqlCmd.ExecuteNonQuery(); ...
If I create a stored procedure using T-SQL in SQL Server Management Studio and define output parameters in this stored procedure, can I call the stored procedure in reporting services and use...
Running the design-time procedure will produce the T-SQL script shown in Figure 1 as output. When this T-SQL script is run, it creates a new Update stored procedure for the Order_Details table. All columns are accounted for as parameters in the new stored procedure code, but notice how ...
I believe the parameter must be declared as output, not as return value:
