SORTING MONTH in SQL

Question

0.00/5 (No votes)

See more:

I have "January",'February", "March"..."December" as ClosingMonth.
I need to sort this and I have the following
sqlString = "SELECT * FROM CustomerListTable ORDER BY ClosingMonth Asc"

But, April comes first.
How I can make January comes first?
Is there any SQL function to change "January" to 1?

What I have tried:

sqlString = "SELECT * FROM CustomerListTable ORDER BY ClosingMonth Asc"

Or, Can I make my own function to change "January" to 1, and insert this function in SQL statement? Could you give any example SQL statement with my own function ConvertMonthToNumber(byval month as string)

In addition to solution #1 by OriginalGriff i'd suggest to convert ClosingMonth to a date[^] data type column to avoid further "on-demand conversions" and due to the performance of query execution.

Solution 1

Either use a table to convert them and a JOIN as part of your SELECT, or append a day and year to it and use the SQL MONTH function:

SELECT MONTH('March' + ' 1 2019')

SQL Server MONTH() Function[^]
