I am having a problem when using the "_" character in a SQL statement.
My query goes like this:
SELECT * FROM PRINCIPALS WHERE NAME LIKE '_'
and all i get are the rows where the lenght of name is equal to 1 character!!! Further testing has proved that every "_" is taken like the "?" in DOS dir command, it replaces one character.
If i wanted to search for a valid name which actually uses the underscore at the beginning of its name, how would i do it then?
Thanks!

Check the syntax of LIKE in the documentation. You can optionally specify an escape character (using the ESCAPE keyword) which indicates that the following character should not be treated as a meta-character, so for example for names beginning with '_' you could do...
WHERE name LIKE '/_%' ESCAPE '/'; |
