I wasn't able to repeat the crash. Could you please provide for us your my.ini file ? Thanks in advance.

This is very probably a duplicate of bug #9526 if you are using UTF-8. Regards, Heikki

The server crash happens when using CREATE TABLE with ENUM column types.
Description: I reported this under 9519 but it has been closed and no-one repsonds to my updates on 9519 as to how and why the problem occurred - Dont you like feedback? Anyway... While adding a table through MySql Query Browser after hitting the execute button..after adding the new table via the "Create New Table" menu. How to repeat: The table to be created was... (VIA Query Browser 1.1.6 and MySql Server 5.0.3) After re-running the query browser the table is visible but viewing the columns displays "could not fetch columns" CREATE TABLE `stock`.`InvestorAnalysis` ( `InvestorId` BIGINT UNSIGNED NOT NULL AUTO_INCREMENT, `Profit` DOUBLE(7,2) UNSIGNED ZEROFILL COMMENT 'Positive value of profits made', `Loss` DOUBLE(7,2) ZEROFILL UNSIGNED COMMENT 'Positive value of losses made', `DateCounter` SMALLINT UNSIGNED ZEROFILL NOT NULL, `Year` SMALLINT UNSIGNED ZEROFILL NOT NULL, `Active` ENUM('Yes','No') NOT NULL COMMENT '0 = Trade Day, !0 = Not a Trade Day', `TradeMade` ENUM('Yes','No') NOT NULL COMMENT '0 = No Trade, !0 = Trade Made', `BestTradeId` BIGINT UNSIGNED, `WorstTradeId` BIGINT UNSIGNED, `CounterType` ENUM('Y','M','W','D') NOT NULL COMMENT 'Y = Year, M = Month, W = Week, D = Days', `Gain` DOUBLE(8,2) NOT NULL COMMENT 'Signed value of overall trade results', PRIMARY KEY(`InvestorId`) ) TYPE = InnoDB; How to repeat: 1. Windows XP Professional. 2. Service Pack 2. 3. MySql Server 5.0.3 beta installed and service running. 4. Install MySql Query Browser 1.1.6 5. I Have no other databases except what is there after installation. 6. I created a database called 'stock' 7. I created 2 tables in the new 'stock' database via the Query Browser GUI. 8. The third table I entered is detailed in previous comments. I manually created the third table again via the Query Browser GUI. 9. Hit the 'Apply Changes' button. 10. Confirm Table edit popup appears with Create Table script as attached. 11. Hit the 'Execute' button. 12. The 'crash' occured in mysqld-nt.exe as specified and program closed after closing 'crash' message box. Suggested fix: Downloaded latest Query Browser 1.1.7. Tried to re-create the table via script that I saved after editing. The query browser crashes. If I remove all the *enum* declarations the table is created successfully.??
