Zeoslib Portal

Hello,

A complete newbie, so be gentle!
Using Delphi 6, Zeoslib 6.6.4 & MySQL 5.1.31 under Windows.

When I try a multi-row update like this:

I get this error message:

"Project quoteit.exe raised exception class EZSQLException with message 'SQL Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'UPDATE LineItemTable SET DesignTime = 55 WHERE Projectnumber=505 AND LineNumber=' at Line 2. Process stopped. Use Step or Run to continue."

The query executes fine if it is only one line.

I have indeed looked in the MySQL manual, but can't find the answer - though I suspect it will turn out to be obvious!

Can anyone help me, please?

Thanks.

hi,
a coma is missing at the end of line 2, maybe ?

I don't think you can execute multiple update statements at once.

Try this
QuotesZQuery.SQL.Clear;
QuotesZQuery.SQL.Add('UPDATE LineItemTable SET DesignTime = ' + IntToStr(55) + ' WHERE Projectnumber=504 AND LineNumber=1;');
QuotesZQuery.ExecSQL;

QuotesZQuery.SQL.Clear;
QuotesZQuery.SQL.Add('UPDATE LineItemTable SET DesignTime = ' + IntToStr(55) + ' WHERE Projectnumber=505 AND LineNumber=1');
QuotesZQuery.ExecSQL;


This way you are executing each statement separately.

Also : you could use the TZSQLProcessor component. That one is made for multiple statements.

Something else : you could put ZConnection1.Properties.Add('CLIENT_MULTI_STATEMENTS=1'); in your code (or add the property line at design time.
Normally that should work as well.

Thank you all.

I'm looking into the TZSQLProcessor component, and it seems to be the solution. Thanks again.
