SQL错误日期与int不兼容

Question

Can Some One help me with this please. I was trying to use this Excel condition in SQL but I am getting error.

EXCEL Condition = "=DATE(2017,MONTH(EOMONTH(B2,0)+1),DAY(EOMONTH(B2,0)+1))"

SQL Query = DATEFROMPARTS(YEAR(GETDATE()),CONVERT(Varchar,
(MONTH(EOMONTH(hiredate,0)+1)),120),CONVERT(Varchar,
(DAY(EOMONTH(HireDate,0)+1)),120)) as 'DATE'  

ERROR: Msg 206, Level 16, State 2, Line 1

Operand type clash: date is incompatible with int

Thank You in Advance

Answer 1

I guess you're trying to get the first day of the month after hiredate , but I can't tell for sure.

This MySQL expression generates that, using the handy-dandy LAST_DAY() function .

      LAST_DAY(hiredate) + INTERVAL 1 DAY

If you want the first day of the month in which hiredate occurs, use this.

      LAST_DAY(hiredate) + INTERVAL 1 DAY - INTERVAL 1 MONTH

If you're working with SQL Server (the Microsoft product) this expression gets you the first day of the month in which hiredate occurs.

   DATEFROMPARTS(YEAR(hiredate), MONTH(hiredate), 1)

This gets you the first day of the next month.

   DATEADD(MONTH, 1,DATEFROMPARTS(YEAR(hiredate), MONTH(hiredate), 1))

As you can see, it's different in SQL Server and MySQL. Job security for data base hackers. The built-in data handling functions deal correctly with stuff like 28, 29, 30, and 31-day months, and leap years, and all those calendar minutiae, so you don't have to.

Answer 2

In Your Query Use DATEADD() Function OF SQL As Shown As Below,This May Work For You.

Use

CONVERT(Varchar,MONTH(DATEADD(dd,1,EOMONTH(GETDATE(),0))),120)

Instead Of

(MONTH(EOMONTH(hiredate,0)+1))
