SQL Case-sensitive select statement

If Column1 of Table1 has following values ‘CaseSearch, casesearch, CASESEARCH, CaSeSeArCh’, following statement will return you all the four records.

SELECT Column1
FROM Table1
WHERE Column1 = 'casesearch'

To make the query case sensitive and retrieve only one record (“casesearch”) from above query, the collation of the query needs to be changed as follows.

SELECT Column1
FROM Table1
WHERE Column1 COLLATE Latin1_General_CS_AS = 'casesearch'

Adding COLLATE Latin1_General_CS_AS makes the search case sensitive.

Default Collation of the SQL Server installation SQL_Latin1_General_CP1_CI_AS is not case sensitive.

To change the collation of the any column for any table permanently run following query.

COLLATE Latin1_General_CS_AS

To know the collation of the column for any table run following Stored Procedure.

EXEC sp_help DatabaseName

Second results set above script will return you collation of database DatabaseName.

SQL – DateDiff

How I figured out that the Sharepoint 180 day trial license ran out: Sharepoint started throwing strange errors, one of them being ‘your trial license has expired’ but other things still working, so I thought maybe this is just a known bug (the bug exists and is well known!) but with no way to tell how old the license is through the licensing page in the admin site which is STUPID, I checked the install date then ran this script in a random database to save me counting wrong.

SELECT DATEADD(dd,DATEDIFF(dd,0,’2013-03-27′)+180,0) ‘Expiry date’
select datediff(day,’2013-03-27′,’2013-09-24′) as ‘Days since installation’

This will copy a table definition only (in MySQL) without data:

create table foo like bar;

Find a column by name (SQL Server 2008)

How to find column within a database with searching by name:
