sql – 使用where子句插入值

我不能直接选择@variables.我必须使用关键字Values.

如何在insert中使用Values时创建where子句.

我试图避免重复

DECLARE @MyID INT
  DECLARE @Phone varchar(10)
  DECLARE @MyDATE DateTime
  DECLARE @Agent as varchar(50)
  DECLARE @Charge as varchar(50)
  DECLARE @Vendor as varchar(50)

  SET @MyID = 215199999
  SET @Phone = '9999999999'
  SET @MyDATE = '2010-12-04 11:56:12.000'
  SET @Agent = 'fbrown'
  SET @Charge = 'NO'
  SET @Vendor = 'NO'

  INSERT INTO [MyDB].[dbo].[Accounts]
  (MyID,Phone,MyDate,Agent,Charge,Vendor)
  VALUES (
  @MyID,@Phone,@MyDATE,@Agent,@Charge,@Vendor 
  ) WHERE MyID NOT IN (@MyID)

解决方法

IF NOT EXISTS(SELECT 1 FROM [MyDB].[dbo].[Accounts] WHERE MyID = @MyID)
    INSERT INTO [MyDB].[dbo].[Accounts]
        (MyID,Vendor)
        VALUES 
        (@MyID,@Vendor)
