New to SQL, Need assistance with Migration


#1

I inherited an in house built program that is being migrated from Access 2003 / SQL 2003 to Access 2010 and SQL 2012. There are queries that are breaking due to changes in SYNTAX etc...

Here is my current problem, please help!
original query that works on 2003 -
"LEFT(DATENAME(month, dbo.Months.FirstOfMonth), 3) + N', ' + RIGHT(DATENAME( dbo.Months.Year, dbo.Months.FirstOfMonth), 2) AS ShipMonth, dbo.Months.YearDotMonth

The problem is that the column within the dbo.Months table is called "Year" which breaks the ability to query it on the newer Access/SQL. I understand that Year has SQL Usage now and that is why I am getting the error "dbo.Months.Year" is not a recognized datename option. When I run the update query to change it to dbo.Months.[Year] within the visual studio database editor, it wont complete the command and still gives me the error.

How do I fix?

Thank you in advance

You would probably want to change:

to:

LEFT(DATENAME(month, dbo.Months.FirstOfMonth), 3) + N', ' + RIGHT(DATENAME(year, dbo.Months.FirstOfMonth), 2) AS ShipMonth

#3

I did change that, but the results set is organized incorrectly then. The organization is by the column data, so the query needs to utilize the column data.

Does that make sense?


#4

From what I can read, you want to "calculate" the ShipMonth, and the format should be "MMM, YY" - correct?
The "datename(month,.....)" extracts the month name and "datename(year,......) will extract the year.
Now - which field contains the shipdate? That's the field name you should put after the comma in the datename function.
Hope this makes sence.

I am teaching myself SQL as I go, so this is all new to me.:slight_smile: I will make the noted changes and see what happens. Thanks again for the quick responses.

I am getting all of the correct data, the issue is that the result set is ordered by Alphabetical Month rather than most recent ship date to oldest ship date. change in bold. Basically, I am wanting the ordering to be the same as the result from the old query.

Thank you in advance!! :grin:

My best guess is, the FirstOfMonth field is not of type date, so if you cast it as a date, you can do the sort:

ORDER BY CAST(dbo.Months.FirstOfMonth AS DATE) DESC
