I would like to wrap my updates top MySQL in transactions.
Use InnoDB tables. PB [EMAIL PROTECTED] wrote:
I apologize if you saw this on the MySQL Forums but I have not gotten a response... Thanks for your help... I know this is probably a stupid question but I could use a nudge in the right direction. I would like to wrap my updates top MySQL in transactions. I am using ODBC as my means of communication (Visual FoxPro is the front end) and passing SQL statements off to the server one Execute at a time. I understand how I could do this with a stored procedure, or possibly even ADO, but I would prefer to send it one command at a time for various reasons. When I send the following series of commands through, though, it doesn't work although each statement tells me that it executed properly: *-- Set the connection string ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};SERVER=localhost;" + ; "DATABASE=test;" + ; "USER=test;"+; "PASSWORD=test;"+; "OPTION=3;" lnHandle = SQLSTRINGCONNECT(ConnectionString) &&Get the connection ? lnHandle &&Check the connection to make sure it worked. lcSQL = "START TRANSACTION" ? SQLEXEC(lnHandle, lcSQL) lcSQL = "BEGIN" ? SQLEXEC(lnHandle, lcSQL) lcSQL = "INSERT INTO n1 (n1) VALUES (1)" ? SQLEXEC(lnHandle, lcSQL) lcSQL = "INSERT INTO n1 (n1) VALUES (2)" ? SQLEXEC(lnHandle, lcSQL) lcSQL = "ROLLBACK" ? SQLEXEC(lnHandle, lcSQL) Yet, when I query the table after this runs, there are still two records despite the fact that I asked it to rollback the transaction and that all commands reported as executing OK. I am sure I am missing something stupid but I cannot find a decent doc on this (if you know of one, a reference would be appreciated). Thanks in advance for your help.
