How do I construct a SELECT query with a WHERE CLAUSE?
For example:
I want to find all records with columnname that has an apple word in it.
I know this query is wrong.
SELECT * FROM TABLE1 WHERE COLUMNNAME is in ('APPLE TART', 'apple', 'apple pie', 'Candy Apple');

Does the case format matter?  Will this query pull records with 'APPLE' too?

Can you give me a select statement using ilike?  I tried it and it did not work.  We have 10g.  My query is SELECT * FROM TABLE1 where columnname ilike '%apple%' and it did not work.

SELECT * FROM table1 WHERE UPPER(columnname) LIKE ('%APPLE%')

the upper makes everything upper case so it will find apple and APPLE the % are wild cards so it will find apple in the middle of results as well e.g it will find "red apple" as well as "apple pie".

if you use _ this is a wild card for a single character eg 'APPLE_' will find apples but not bapples or red apple or apple pie

hope this helps

ILIKE is a PostgreSQL keyword, not Oracle

You can also use  INSTR:

select *

from table1

where INSTR(lower(columnname), 'apple')>0
