Thread: naming conventions constraint

naming conventions constraint

From
"Julian North"
Date:
I'm at the very beginning of working with postgres.

The aim is to replace / build a number of very large and very complex
database currently residing in Oracle, MSSQL and Informix.

In order to coordinate across a medium size DBA team I instituted a standard
constraint naming convention suitable for the above 3 platforms.

For example a foreign key would be FK_table#reftable#column.

Unfortunately I don't appear to be able to use it with postgres.

This is because I can't use the # character in constraint names.

Does anybody have any suggestions as to an alternative that is also a single
char? (I'm limited to 30 chars cos of oracle and manyof the current names at
the limit).

Any help appreciated,



Julian.

You need to quote strings which contain special characters.
