Hello ism,

The problem is not in the Zeos Lib.

When a STORED PROCEDURE in MySQL returns a Result Set, you must specify this using the directives READS SQL DATA or MODIFIES SQL DATE.

More details: http://dev.mysql.com/doc/refman/5.0/en/ ... edure.html

Best regards,

Hello,

Another way to solve the problem is to enable the property CleanupStatements of TZSQLProcessor.

When this property is enabled the tokenizer removes all comments from the script.

Hello tarnschaf , I checked the SQL script to understand the problem. Until a solution is available, I suggest to solve the problem another way: use the same delimiter throughout the length of the script. Example: CREATE TABLE L4PARTS ( ID Integer NOT NULL, "Nummer" VarChar(22), "Arti...

Hello elidorio2

Use the ParamByName to retrieve the value setted up to parameters of TZQuery. Example:

Code: Select all

var
   I: Integer;
begin
   ZQuery1.ParamByName('col1').AsInteger := 9;
   I := ZQuery1.ParamByName('col1').AsInteger;
   {...}
end;
Bye, bye

Hi,

Verify your MySQL version. "Before 5.0.3, BIT is a synonym for TINYINT(1).".
