Обсуждение: [GENERAL] ODBC driver issue
Hi, I'm testing my program and got an interesting issue. I have an OSX 10.8 with iODBC manager and PostgreSQL ODBC driver. When I tried to query the database table with the column "char(129)" I get: "My field text " (the text with the bunch of spaces at the end). The driver is not the current one - but I don't remember the version. Is this known issue? Maybe its already fixed with the latest ODBC driver? Thank you.

Maybe its already fixed with the latest ODBC driver? a char(129) field is 129 characters long, and will always be padded with spaces to that length. maybe you wanted a varchar (aka char varying) ? these are variable length and return just what you put in them. -- john r pierce, recycling bits in santa cruz

With the char(), is there a "Standard SQL" way to do trimming?
