Case insensitive LIKE for BLOB field??

Thankyou for considering my question.

I have a table that includes some memo text stored in a BLOB field. I need to select rows from this table where the TEXT BLOB FIELD contains a keyword the user has entered, this works fine using the code

Code:

... WHERE MYMEMODATA LIKE '%keyword%'

I have found that I can't use the UPPER() command on a BLOB field.

How can I make this where clause case insensitive?

Maybe you could try this:
WHERE MYMEMODATA LIKE 'keyword' OR 'KEYWORD'

This will work for basic ASCII characters:

Code:

... WHERE MYMEMODATA CONTAINING 'keyword'

If your blobs contain national characters, you would have to write UDF.

It is not complete

, you would have to write:
WHERE mymemo LIKE '%keyword%' OR mymemo LIKE '%Keyword%' OR mymemo LIKE '%KEyword%' OR mymemo LIKE '%KEYword%' OR mymemo LIKE '%kEyword%' OR ...

Yes this does it well!!! The blobs don't contain national characters at this stage so it will do the job just fine. Thankyou.
