First check if you are in the right database USE yourDB and try Select   from contenttype just to see what is it and if it exists really

Sounds like you have Schroedinger s table      Seriously now  you probably have a broken table  Try    DROP TABLE IF EXISTS contenttype REPAIR TABLE contenttype If you have sufficient permissions  delete the data files  in  mysql data db name

Same problem occurred with me while creating a view  The view was present earlier then due to some changes it got removed But when I tried to add it again it was showing me  view already exists  error message   Solution    You can do one thing manually    Go to the MySQL folder where you have installed it Go to the data folder inside it  Choose your database and go inside it  Data base creates   frm  format files  delete the particular table s file  Now create the table again    It will create the table successfully

Encountering the same problem  create InnoDB table  this is what finally worked for me   DROP DATABASE  having issues     I checked on a file basis  permissions  tried to REPAIR and FLUSH but nothing worked   So if this is an option  move all working tables to another DATABASE  drop the old one  you might have to manually remove any files from the database folder before the drop to work   rename the new one  and you  should  be back on your way  Apparently  whatever gets  cached  using InnoDB is dropped along with the original database

I ve just had the same error but I knew the table already existed and wanted to add to it  I m adding my answer as this question comes up as no 1 for me on google when looking for the same error but for a slightly different scenario  Basically I needed to tick   Add DROP TABLE   VIEW   PROCEDURE   FUNCTION   EVENT   TRIGGER statement   And this solved the error for me

I had this problem on Win7 in Sql Maestro for MySql 12 3  Enormously irritating  a show stopper in fact  Nothing helped  not even dropping and recreating the database  I have this same setup on XP and it works there  so after reading your answers about permissions I realized that it must be Win7 permissions related  So I ran MySql as administrator and even though Sql Maestro was run normally  the error disappeared  So it must have been a permissions issue between Win7 and MySql

I had this same problem and it looks like the Database name was case sensitive  My Database is called   Mydatabase   Whilst my script included  USE mydatabase   Once I changed the database name to the correct case it all seemed to work  Using MYSQL Workbench on MAC OSX

You may need to flush the table cache   For example   DROP TABLE IF EXISTS  tablename    FLUSH TABLES  tablename       or exclude  tablename  to flush all tables    CREATE TABLE  tablename

I was having huge issues with Error 1050 and 150   The problem  for me was that I was trying to add a constraint with ON DELETE SET NULL as one of the conditions    Changing to ON DELETE NO ACTION allowed me to add the required FK constraints   Unfortunately the MySql error messages are utterly unhelpful so I had to find this solution iteratively and with the help of the answers to the question above

In my case I found this to be an issue with InnoDB  I never discovered what the actual problem was  but creating as a MyISAM allowed it to build

from MySQL Log   InnoDB  You can drop the orphaned table inside InnoDB by InnoDB  creating an InnoDB table with the same name in another InnoDB  database and copying the  frm file to the current database  InnoDB  Then MySQL thinks the table exists  and DROP TABLE will InnoDB  succeed

I am struggling with the same issue   I cannot create a table  even though it does not exist  I tried all the above solutions with no success   My solution was to delete the files ib logfil0  ib logfile1  ibdata1  and auto cnf from the data folder of MySQL  make sure to stop the MySQL service first before deleting these files   Then after restarting the service  MySQL recreated these files and I was able to run a backup script were all my CREATEs were stored  a sqldump file

My CREATE statement was part of staging env dump   I did try everything that has been mentioned above  I DID NOT get solution  However my path to  redemption was    I stumble upon the fact that  one of many in  the CREATE statement did get through when I rectified the database name case sensitivity  This clicked something  I repeated the same for the other tables  However a new error came into the scene  The straight quotes for  comments   were throwing syntax error  I was shocked  replaced them but the new error started popping up  Finally i knew the solution    SOLUTION  The dump i was using might have been from a different version of MySql  I got permission to connect to the staging MYsql using the local installed on my machine  mysql workbench  I did not rdp into the staging server to login to staging mysql workbench  Created a dump from there  Ran the dump and it worked like a sweet

In my case the problem was that there was a view with the same name as my table  so I had to drop the view to allow the import to continue   drop view  my-view-that-has-same-name-as-table     An automated solution that worked for me is to replace the normal drop table with this sed during the dump to also drop any views that might exist   mysqldump my-db     sed -E  s  DROP TABLE IF EXISTS       0 DROP VIEW IF EXISTS 1 g      mysql my-other-db   Or if you would rather print to a file for backup  mysqldump my-db     sed -E  s  DROP TABLE IF EXISTS       0 DROP VIEW IF EXISTS 1 g     gt  my-db dump sql   Or if you received the dumped file and you are importing it to your db  cat my-db dump sql     sed -E  s  DROP TABLE IF EXISTS       0 DROP VIEW IF EXISTS 1 g      mysql my-other-db   You get the idea  Note  it is important that you add the   at the beginning of the replacement regex  because there are other types of DROP TABLE IF EXISTS commands in dumps that you don t want to touch   You go from having something like this   -- -- Table structure for table  my table  --  DROP TABLE IF EXISTS  my table      40101 SET  saved cs client         character set client        40101 SET character set client   utf8     CREATE TABLE  my table          To having something like this   -- -- Table structure for table  my table  --  DROP TABLE IF EXISTS  my table   DROP VIEW IF EXISTS  my table      40101 SET  saved cs client         character set client        40101 SET character set client   utf8     CREATE TABLE  my table

For me the problem was caused when using a filesystem copy of the mysql database directory instead of mysqldump   I have some very large tables  mostly MyISAM and a few InnoDB cache tables and it is not practical to mysqldump the data   Since we are still running MyISAM  XtraBackup is not an option    The same symptoms as above happened to me   The table is not there  there are no files in the directory that pertain to the table  yet it cannot be created because MySQL thinks its there   Drop table says it s not there  create table says it is     The problem occurred on two machines  both were fixed by copying backups   However  I noticed that in my backup that there was a  MYD and  MYI file  even though I was under the impression that these files are not used for InnoDB   The  MYD and  MYI files had an owner of root  while the  frm was owned by mysql    If you copy from backup  check the file permissions   Flush tables might work  but I opted to shut down and restart the database     Good luck
