Re: I can't have "group" as a column name in a table? [SOLVED]
Aveek, Simcha, Johan, Thanks for explaining the situation. I knew there were some reserved words, but I hadn't realized there were so many. Anyway, now that I know I can protect my column names with backticks, I'm good to go. -- Dave M G -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Simple quotes have started to work in more and more places in newer versions of MySQL. However, it is considered bad form to name columns for reserved words - even ones as obvious as "group" or "index". Bad form in the same way that you wouldn't name any variables "define" or "if" while programming; or in a very similar way that you wouldn't put a box of TNT next to a burning candle - it's an accident waiting to happen. The escapes are there in case an upgrade creates new reserved words that you've already used in column names - "partition" comes to mind - but if you are still in a phase where you can avoid using reserved words, please spare yourself and others a lot of trouble and do so; even if only because while you can fix your code, you can't fix someone else's - think management tools, backup scripts, whatever may touch the db in the future. -- Bier met grenadyn Is als mosterd by den wyn Sy die't drinkt, is eene kwezel Hy die't drinkt, is ras een ezel

Re: I can't have "group" as a column name in a table?
Use a quote around the column name or explicitly specify the column as . (as for e.g. mytable.group) in the query.

I can't have "group" as a column name in a table?
MySQL users, Simple question: In one table in my database, the column was named "group". I kept getting failed query errors until I renamed the column. I've never before encountered a situation where MySQL mistook a column name for part of the query syntax. Should I never use the word "group" for column names? Seems a little silly. Is there a way to protect column names to that there is no confusion? -- Dave M G -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
