Hi,
If at all possible, normalizing the data is far and away the best solution.
Failing that, you can use regular expressions
RLIKE REPLACE(col, ' ', '|')
or INSTR(....). Another solution is fulltext search, but it would have many
limitations depending on what you really need to do. Otherwise, try the
approaches given here: http://www.sommarskog.se/arrays-in-sql.html
But prepare yourself for some deep thinking if you want to understand how they
work, especially the one that works against a table of numbers; it's a little
murky, though it is probably the best of the solutions.

Hello all. I have a query I am tring to implement and I can't wrap my
mind around it somehow. Can anyone help?
.
I have two tables within a database.
Within the first table, I have a blob field that basically has a large
amount of text.
Within the second table, I have a list of strings (in this case
application names).
Is there some way that I can search the blob for any occurrence of any
of the strings? (returning the string name)?
There could be more than 1 match.
Any ideas?
Thank you for any help you may offer.
Craig
