The server is running: PostgreSQL version 7.0.2 RedHat Linux 6.2 When using ORDER BY in an SQL statement where the data type is varchar and the data are unix directory paths, the forward slashes (/) are ignored, causing the results to be returned in the incorrect order. Example: Here is the INPUT: /usr/local/data/x/d /usr/local/data/xc/e /usr/local/data/x/a /usr/local/data/xc /usr/local/data/x/b Here is the QUERY: SELECT * FROM mytable ORDER BY path Here is the OUTPUT: /usr/local/data/x/a /usr/local/data/x/b /usr/local/data/xc /usr/local/data/xc/e /usr/local/data/x/d Note that the program appears to make no distinction between /x/c and /xc. I could be wrong, but I believe that the output order should be as follows: Here is the OUTPUT I expected: /usr/local/data/x/a /usr/local/data/x/b /usr/local/data/x/d /usr/local/data/xc /usr/local/data/xc/e ---------- Kristian T.
