Hello, We're porting a huge Library Management System, written using all kind of languages one can think of (C, C++, ESQL/C, Perl, Java, ...) on Linux from the DBS Sybase to PG, millions of lines of code, which works also with DBS Oracle and in the past with INFORMIX-SE and -ONLINE. We got to know that in CHAR columns with trailing blanks a SELECT ... FROM ... WHERE name LIKE 'Ali' does not match in 'name' having 'Ali '.
Did you forget the "%"? Because the SQL standard which PostgreSQL follows is: SELECT ... FROM ... WHERE name LIKE 'Ali%'
I glanced through our code with grep pipelines and found some hundred places which would be affected by this problem. I'm not interested in a religious discussion if or if not this behaviour of PG is correcter or better than in Sybase. It's just different to Sybase.
SQL Server derives from Sybase, and it would also fail on this statement.
Any hints to address this problem? Or is there any compile time option for the PG server to address this? Thanks matthias
