MySql with HP-UX
Posted on 2013-01-02
Hello,
I'm trying to use a simple mysql query using the where option. I looked at a manual that I have and I can't this statement to work. I wonder if there is some setting I am missing.
This statement works; select service from XXXinstances where service='XXX_3';
There are many of each X types. There are X_1, XX_2, and XXXX_4, etc.
I'm trying to use a wide card %, like this;
select service from XXXinstances where service='%_3';
To select all of the _3 types/services.
Why does this not work?

With a wild card, you need to switch from = to LIKE. Your query should be this:
select service from XXXinstances where service like '%_3';
select service from XXXinstances where service like '%_3';
Can you try using like instead of =
... where service like '%_3';
edit: after posting I saw the above 2 replies..
... where service like '%_3';

Even with the LIKE syntax above beware that the '_' is a single character wildcard so it will match 'abcdef3'.
You will need to escape the '_'.
select ... like '%\_3';
