Hello Wout, > Appareantly it's impossible to insert a string, consisting entirely out of > spaces, in a textual field (I've tried varchar(19) and char(2) types, they > both don't work). MySQL doesn't complain about it, but it trims the strings > down to the empty string. If I try a select searching for the spaces-only > string afterwards, it gives me zero results.

Any help would be greatly appreciated!
Please note the last few lines of each msg on this list. It required five seconds and the first 'hit' on a single search of the manual to find a reference. Please read the (fine) manual: 6.2.3.1 The CHAR and VARCHAR Types The CHAR and VARCHAR types are similar, but differ in the way they are stored and retrieved. The length of a CHAR column is fixed to the length that you declare when you create the table. The length can be any value between 1 and 255. (As of MySQL Version 3.23, the length of CHAR may be 0 to 255.) When CHAR values are stored, they are right-padded with spaces to the specified length. When CHAR values are retrieved, trailing spaces are removed.
