MySQL "CREATE TABLE IF NOT EXISTS" -> Error 1050

Using the command:

CREATE TABLE IF NOT EXISTS `test`.`t1` (
    `col` VARCHAR(16) NOT NULL
) ENGINE=MEMORY;

Running this twice in the MySQL Query Browser results in:

Table 't1' already exists Error 1050

I would have thought that creating the table "IF NOT EXISTS" would not throw errors. Am I missing something or is this a bug? I am running version 5.1. Thanks.


Works fine for me in 5.0.27

I just get a warning (not an error) that the table exists;


As already stated, it's a warning not an error, but (if like me) you want things to run without warnings, you can disable that warning, then re-enable it again when you're done.

SET sql_notes = 0;      -- Temporarily disable the "Table already exists" warning
CREATE TABLE IF NOT EXISTS ...
SET sql_notes = 1;      -- And then re-enable the warning again

You can use the following query to create a table to a particular database in MySql.

create database if not exists `test`;

USE `test`;

SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;

/*Table structure for table `test` */

CREATE TABLE IF NOT EXISTS `tblsample` (

  `id` int(11) NOT NULL auto_increment,   
  `recid` int(11) NOT NULL default '0',       
  `cvfilename` varchar(250)  NOT NULL default '',     
  `cvpagenumber`  int(11) NULL,     
  `cilineno` int(11)  NULL,    
  `batchname`  varchar(100) NOT NULL default '',
  `type` varchar(20) NOT NULL default '',    
  `data` varchar(100) NOT NULL default '',
   PRIMARY KEY  (`id`)

);

create database if not exists `test`;

USE `test`;

SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;

/*Table structure for table `test` */

***CREATE TABLE IF NOT EXISTS `tblsample` (
  `id` int(11) NOT NULL auto_increment,   
  `recid` int(11) NOT NULL default '0',       
  `cvfilename` varchar(250)  NOT NULL default '',     
  `cvpagenumber`  int(11) NULL,     
  `cilineno` int(11)  NULL,    
  `batchname`  varchar(100) NOT NULL default '',
  `type` varchar(20) NOT NULL default '',    
  `data` varchar(100) NOT NULL default '',
   PRIMARY KEY  (`id`)
