1:SqlServer简单的操作XML:
ALTER PROCEDURE [dbo].[SP_CRM_FranchiseeRecharge_Money] @Create_By VARCHAR(50), @xmlStr1 NVARCHAR(MAX) -写在这里面的为 传入的参数 AS BEGIN as begin后面的为自定义的变量 SET NOCOUNT ON; DECLARE @xml XML = @xmlStr1; sqlserver操作XML T-SQL提供了以下几个针对XML类型的查询函数: query(XQuery):利用Xquery查询符合条件的元素集合。 value(XQuery,Type):利用Xquery查询具体元素的值,Type定义值的类型。 exist(XQuery):利用Xquery查询是否存在符合条件的元素。 nodes(XQuery):利用Xquery获得一个结果集。 INSERT INTO qqtest(xmlinfo) xmlinfo 为字符串类型 VALUES( N‘<root> <person> <id>F001</id> <name>F001</name> <age>18</age> </person> </root>‘ ) DECLARE @errorCode INT; DECLARE @errorMsg VARCHAR(2000); BEGIN TRY SET @errorCode = 0; SET @errorMsg = ‘‘; DECLARE @xml XML; SELECT @xml = xmlinfo FROM dbo.qqtest WHERE id =6; SELECT S.value(‘id[1]‘, ‘varchar(30)‘) id, S.value(‘name[1]‘, ‘varchar(30)‘) _Name, S.value(‘age[1]‘, ‘varchar(30)‘) age FROM @xml.nodes(‘/root/person‘) AS A(S); //B(S) 都是没有问题的 @xml.nodes(‘/root/person‘) AS A(S) 当做一张表来操作了 SET @errorCode = 200; END TRY BEGIN CATCH SET @errorCode = 500; SET @errorMsg = ERROR_MESSAGE(); RAISERROR(N‘error:XML文件格式错误:‘, 16, 1,@errorMsg); PRINT(@errorMsg) END CATCH 获取XML数据 ,把XML数据当做一个表格 @xml.nodes(‘/Root/data‘) AS T(S); select S.value(‘ID[1]‘,‘int‘)as ID, S.value(‘Name[1]‘,‘nvarchar(50)‘)as Name FROM @xml.nodes(‘/Root/data‘) AS T(S); 2 写入临时表 INSERT INTO #tbCRM_FranchiseeRecharge ( [Recharge_ID], [Franchisee_ID], [Recharge_Credit], [Recharge_Amount] ) SELECT DISTINCT NEWID(), S.value(‘Franchisee_ID[1]‘, ‘uniqueidentifier‘) AS Franchisee_ID, S.value(‘Recharge_Credit[1]‘, ‘int‘) AS Recharge_Credit, S.value(‘Recharge_Amount[1]‘, ‘money‘) AS Recharge_Amount FROM @xml.nodes(‘/Root/data‘) AS T(S);
2:SQl语句简单的 try catch 的统一格式:如下简单的Sql
string sql = @"BEGIN SET @insertStateCode = 0; IF NOT EXISTS ( SELECT TOP 1 * FROM tbCRM_Franchisee_Credit_History WHERE Seq [email protected] ) BEGIN TRY BEGIN TRAN mytran; INSERT INTO tbCRM_Franchisee_Credit_History ( [Seq], [Franchisee_ID], [Tran_Code], [Tran_By], [Tran_Date], [Credit], [Amount], [Remark] ) SELECT RM.Recharge_ID, RM.Franchisee_ID, 5, RM.Create_By, GETDATE(), RM.Recharge_Credit, RM.Recharge_Amount, RM.Remark FROM tbCRM_Franchisee_Recharge_Master RM WHERE RM.Recharge_ID = @rechangeID; UPDATE tbCRM_Franchisee_Recharge_Master SET Approve_By = 1 WHERE Recharge_ID [email protected]; SELECT @insertStateCode =200; COMMIT TRAN mytran; END TRY BEGIN CATCH SELECT @insertStateCode = 500; ROLLBACK TRAN mytran; END CATCH; END;"; 其实就是简单如下:
BEGIN TRY BEGIN TRAN mytran;
END TRY BEGIN CATCH SELECT @insertStateCode = 500; ROLLBACK TRAN mytran; END CATCH;
