Error: DATEPART does not exist, frp, SQL to select last months records

Question

I'm trying to get an SQL query to select all records from last month, I have this which from looking numerous places is exactly what I should need, and should work:

SELECT *
FROM orders
WHERE DATEPART(yy,DateOrdered) = DATEPART(yy,DATEADD(m,-1,GETDATE()))
AND DATEPART(m,DateOrdered) = DATEPART(m,DATEADD(m,-1,GETDATE()))

However I keep getting the error:

#1305 - FUNCTION retail.DATEPART does not exist

The query I'm using is word for word from other answers on here, yet I'm getting this error.

Thank you for any help -Tom

Answer 1

DATEPART is a Transact-SQL function, usable with Microsoft SQL Server. From the question tags, I assume you are using MySQL as your Database Management System.

Take a look at MySQL DATEDIFF

Answer 2

That would not work in mysql. To translate that to mysql you could do:

SELECT *
FROM orders
WHERE YEAR(DateOrdered) = YEAR(DATE_SUB(CURDATE(), INTERVAL -1 MONTH))
AND MONTH(DateOrdered) = MONTH(DATE_SUB(CURDATE(), INTERVAL -1 MONTH))

See here for the date functions available in mysql.

Answer 3

It will also work.

SELECT * 
FROM orders 
WHERE  MONTH(DateOrdered) = MONTH(CURRENT_DATE() - INTERVAL 1 MONTH) 
AND YEAR(DateOrdered) = YEAR(CURRENT_DATE() - INTERVAL 1 MONTH)
