Обсуждение: Turning of case sensitivity for identifiers?
Hi all, Is it possible to turn of the case sensitivity for tables and columns in queries (to all CAPS)? I have a (closed source)tool that I have to use (Clarion) that generates the queries and I cannot change the way the tool generates the queries. Groeten, Joost Kraaijeveld Askesis B.V.

The table and column names are not actually case sensitive; they are just folded to lower case while you apparently expect upper case. If you write the names the same way in each command, there should not be a problem. What problem are you actually seeing? -- Peter Eisentraut http://developer.postgresql.org/~petere/

I am unsure of the translation of "fold". Is that the same as translate? Does that mean that if Postgresql get a query withoutquotes it translates the schema/column/table to lower case automatically? > If you write the names the same way in each command, there should not be a > problem. I cannot see how Clarion creates the queries. I have to deduct it from a log file that does not show me the query as-is butgives a "user friendly" translation of the query, without any quotes. > What problem are you actually seeing? Clarion checks whether the table is valid. For that, it seems to do an ODBC SQLColumns which returns the schema/table/columnname in lower case while Clarino is expecting it to be uppercase. Hence it says that the table is notvalid (it seems to find the table but not the columns). On a DB2 database (that has all caps names) it works. Groeten, Joost Kraaijeveld Askesis B.V.

It's not currently possible to turn off case folding or to force spec complient upper case folding. You may want to look through the archives for the discussions if you wish to add something.

That's easily fixed. Turn on log_statement in postgresql's
configuration file and look at the server-side log to see what Clarion
is sending.
