I don't like such prefixes because they make it easier to lie or make mistakes. I've seen people try for hours to figure out why something doesn't make sense, only to find out that the index whose name has a 'U' in it actually wasn't created with the "UNIQUE" attribute.
Names falsely cause reliance that cannot be trusted. Making reports on such things easier to run is, to my mind, a better idea than integrating too much information into naming standards.

Seems I have to play devil's advocate on this one. So, you see no purpose to index names such as: P_EMPLOYEE for a Primary key on the employee table or UM_METER_CODE for a unique index on the meter table meter_code column or FE_DEPT for a foreign key index on the employee table dept column or IIE_LOG_DATE for a non-unique index on the import_export table log_date column? The first letter doesn't help me figure out that the object is an index, but it sure helps to show what the index is being used for. Constraint naming is another area where we use a one character prefix to identify the constraint type, in part to conform to index naming. The keeper of standards here (not me) has also imposed prefix conventions on global temporary tables and on selected classes of tables such as work tables or external cross reference tables. It does help keep the developers in line. Kevin Kennedy First Point Energy Corporation If you take RAC out of Oracle you get OLE!

Why do you say stay away from this? -----Original Message----- Sent: Tuesday, July 30, 2002 5:10 PM To: Multiple recipients of list ORACLE-L Here's a start. Not a checklist by any means, just kind of a micro pet peeves list. * Decide today whether table names will be singular or plural. Do you want a THING (singular) table? Or a THINGS (plural) table? * Don't use case-sensitive names. E.g., use THING (without quotes) in your CREATE (DDL) statement, which can be spelled "THING", "thing", "Thing", or even "tHiNG" in your developers' SQL. But don't make developers type stuff like this... select "Name" from "Thing" where "Id" = y /* won't work without "" */ * Don't embed the object type in the object's name. I used to see this all the time with tablespaces called XYZ_TS, indexes called IND_THING, and so on. * Decide today whether you want to abbreviate or not. If you do, then construct a formal, standard, consistent list of accepted abbreviations. Don't name one table CUSTOMER_THING and another CUST_HISTORY.

Will some of you please provide some insight on your table naming conventions? I'm in the very early planning stages of what will likely be a large and complex schema (IT asset inventory). I have a chance to start it correctly.
