Does a table exist? Oracle and MySQL check Posted by enquirer (enquirer), 19 March 2003 In my knowledge there are two different ways to check if a table in MySQL/Oracle database already exists: In Oracle select count(table_name) from all_tables where table_name = 'TABLE' In MySQL show tables like 'TABLE' Is there any common way for this, which can work with both the databases? Posted by admin (Graham Ellis), 19 March 2003 I would useDESCRIBE tablename which is provided in MySQL to provide Oracle compatability; if you get a good result back, the table exists. If your SQL request fails, it doesn't exist. With modules like the Perl DBI, you simply check the return from the request to see if it's a true value. Posted by waygood (waygood), 1 July 2003 This is bad practice as you are treating a failure as a desired result, a failure may occur for other reasons.Try using "SHOW TABLES" instead, it will not fall over but you do have to search through the results for the table concerned.
