Calling several times the same SP into a cycle (do while) with VisualFox it lost the connection with the MySQL server. I'm using MySQL Server 5.0.22 , VFOX 9.0 and ODBC Driver 3.5.12, the quantity of time can change but i dont know the reason why, regard.

How to repeat:

vueltas = 0

DO WHILE (lnRes1 = 1 AND lnRes2 = 1) OR LASTKEY() = 27
	lnRes1 = SQLEXEC(lnCon, "CALL SP_ReporteCalculoTerminacion(3,4,1,2,'2006-01-01',.15,0)", "temp")

vueltas = vueltas + 1



? vueltas

Thank you for a problem report. Please, try to repeat with a newer version, 5.0.24a, and inform about the results. In case of similar crashes, please, send complete text of your stored procedure, and SHOW CREATE TABLE results for all tables referenced in it.

I am having a very similar problem.  It may even be the same problem.  I don't know what the breaking point was though.... 

We have a production 4.0.18 system and a development 5.0.24a (& a 5.0.27) system.  We are trying to phase out the version 4 system.  Currently, we are running both side-by-side.  We have been rewriting a lot of our .NET code to the version 5 system and utilizing Stored Procedures.  This has been working fine for weeks until today!

All our .NET programs that are utilizing the stored procedures are crashing with an error message "Connection Lost".  Even an existing Crystal Report that utilizes a stored procedure is failing; this report was working and has not been changed nor has the stored procedure.  The report will run fine with partial data when the "Call" to the stored procedure is removed.  I have tried recompiling the procedures and even dropping them and re-entering them to no avail.  All this is against the 5.0.24a system mind you.

Finally, I loaded MySQL 5.0.27 on my system.  I copied the database over to my machine, changed the ODBC connection to point to my machine and the same thing is occuring.  

I should mention that all the stored procedures work fine on both machine (5.0.24a & 5.0.27) when run from a mysql command prompt.

Just to add to my previous comment... this is on Windows 2000 & Windows XP (5.0.24a & 5.0.27 respectivly)
