Hi,
my application runs long time with no problems under MyDac up to 3.30 , MySQL 4.0.*. and Delphi 7
Since the update to mysql 4.1.7 and MyDac 3.30.*, massive problems occur. I get some Debugger-Exceptions:
'EAssertionFailed: Unknown MySQL datatype (32) (D:\Projects\Delphi\MyDac\Source\MyClasses.pas, Line 870)'.
The shows path dosen´t exist: D:\Projects\Delphi\MyDac\Source\MyClasses.pas
The errors occurs irregular, sometimes at very simple SQL-Statements.
select * from anytable
The statements run fine in mysqlcc or mysql query browser.
I´ve uninstall and reinstall all mydac and mysql-products with no change.
Did you have any suggestions?
Bye
Harald
Problems with MyDac 3.30.1.13 and MySql 4.1.7
Re: Problems with MyDac 3.30.1.13 and MySql 4.1.7
This error might happen if MySQL server returns unknown type of the field. But there is no description of type with code 32 in mysql_com.h .
Probably, on update from MySQL 4.0 to 4.1 some tables with data were damaged. Try to make a check of these tables.
