Hi Donna, You have to include the column `type` in the SQL-statement, otherwise the not specified column will have its indirect null translated to an empty string or 0 (for strings/numeric).
A bug or a feature? Actually I've used it as a feature sometimes when using MySQL to move large amount of dirty data between different systems. Be careful when not including NOT NULL columns in your inserts... To get around the problem and get more background info, read: http://dev.mysql.com/doc/mysql/en/constraint_NOT_NULL.html Regards, Thomas Lundström, Ongame E-Solutions AB -----Original Message----- From: Donna Hinshaw [mailto:[EMAIL PROTECTED] Sent: den 21 september 2004 21:07 To: [EMAIL PROTECTED] Subject: inserting null to not null columns Hi folks: I have an InnoDB database, the tables created using MySQL Control Center 0.9.4-beta (winXP pro platform). Each table has some columns which I have checked as Nulls Allowed. I am building a pure Java GUI to the database. Got the SQL statements working fine, but have discovered that I can successfully insert rows into a table without including a value for a column which should be blocking nulls. e.g. Table A -------- id (PK, auto increment) name type ssn ( nulls allowed specified) ==> name and type do not have nulls allowed specified, so I think they should be NOT NULL. they also have no default specified. then.... insert into A (id,name,ssn) values (NULL,"Jane",999999999) this statement works fine, but I think it should give me an error by saying that I'm trying to insert a row without providing a value for the type column (which has no default specified). Looking at the create statement for the tables, MySQL Control Center has supplied defaults of blanks...can I turn off that "preference" ? using MySQL 4.0.18 Can anyone provide clarification? thanks...
