pymssql调用sqlserver存储过程带output 参数

直接上代码

def api_adddept():
    data = json.loads(request.get_data())
    userdata={}
    
    with UseDataBaseSQLServer() as cursor:

        msg=cursor.callproc(‘[AppData].[dbo].[Fyit_AddDept]‘, (data["parentdept_add"],data["deptname_add"],1,pymssql.output(str),pymssql.output(str)))
        userdata[‘result_code‘]=msg[3]
        userdata[‘result_msg‘]=msg[4]
        
        # sql=‘DECLARE @return_value int,@result_code nvarchar(1024),@result_msg nvarchar(1024);‘
        #     ‘EXEC @return_value = [AppData].[dbo].[Fyit_AddDept] @parentid = {0},@dept = N‘{1}‘,@display = 1,@result_code = @result_code OUTPUT,@result_msg = @result_msg OUTPUT;‘
        #     ‘SELECT    @result_code as N‘@result_code‘,@result_msg as N‘@result_msg‘,@return_value as N‘Return Value‘;‘

        # cursor.execute(sql.format(data["parentdept_add"],data["deptname_add"]))  
        # result = cursor.fetchone()  

        # while result:
        #     userdata[‘resultcode‘]=str(result[0])
        #     userdata[‘resultmsg‘]=result[0]
        #     userdata[‘returnvalue‘]=str(result[2])
        #     break

    resp = jsonify(userdata)
    resp.status_code = 200
    return resp

 

其上两种写法都可行。

第一种简单，方便。第二种还要自己拼SQL。
