SEARCH in TEXT field type in CASE SENSITIVE MS SQL SERVER 2000 Database

Hi friends,

I am having a problem with a simple select query which can be displayed as follows:

SELECT ID, NAME
FROM TABLE1
WHERE TABLE1.TEXTFIELD1 LIKE '%MySearchText%'

Since the Database is case sensitive I will have to use the UPPER function in the statement but the TEXT field type in the Database doesn't support this function.

Making database case insesitive in run time is not advisable since the database is shared in the network.

Is there anyone around who can help me?

Change the collation in the statement to an non case sensitive collation using the COLLATE function.

Thanks for participation tonyhowarth.

I got it how to do it.

the thing is if I CAST the field in VARCHAR within WHERE clause then I can use the UPPER function.

so the statement would look like this:

SELECT ID, NAME
FROM TABLE1
WHERE UPPER(CAST(TABLE1.TEXTFIELD1)) LIKE UPPER('%MySearchText%')

Thanks once again

Yep, that's fine, but I would check the performance of the SQL with and without the UPPER.  Using a function in the where means that usage of indexes is adversely affected.

Please do it as I m not expert in SQL so I was also thinking about that.

Pleas let me know if you have better than this.

Also please give me the code using the COLLATE function if you can.

Thanks

Doh....I may have mislead you slightly.  I went back to look at the code that I wrote to do this and it appears that the case sensitivity is handled on a Left Outer Join, as you can see below.

I am not sure you can do this on a WHERE clause.

SELECT Table1.*,Table2.* FROM Table1 LEFT OUTER JOIN Table2 ON Table1.Code = Table1.Code_Ref COLLATE SQL_Latin1_General_CP1_CI_AS


Sorry
