Hi,
I've got a varchar field in a mysql table that contains 'N' numbers (each a maximum of 4 digits, not zero padded) separated by spaces when more than 1 number is present.
eg. field content might be any of the following
''
'123 4567 1234 45 3'
'3'
'3 4 6'
I want to select only those records that do not contain a certain number.
Problem I have with using LIKE "%MyNum%" is that obviously this is going to match "3" against "123" which I don't want it to.
Is there something I can use like Perl's "word boundary" pattern match code?
My statement so far is:
SELECT * FROM MyTable WHERE RefList NOT RLIKE "\bMyNum\b" # Where \b is a word boundary
Yes, you can use REGEXP and the ugly [[:<:]] and [[:>:]] markers:
... WHERE RefList NOT REGEXP '[[:<:]]MyNum[[:>:]]' ...
