问题
I have managed to make my Access work as a frontend for MySQL. I have managed to make it work through connection string but because some specifics in code i would like to save DSN configuration as user DSN.
I have ran into one specific problem. I need to use option=3 inside my connection string because without option=3 i get error: The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
If i include option=3 in my connection string everything works well. The thing is, in Mysql Connector/ODBC data source configuration i do not know which checkbox/option represents option=3
回答1:
The doc about this is here : Connector/ODBC Connection Parameters
option=3 looks deprecated as specified in this answer :
Option=3;corresponded toFLAG_FIELD_LENGTH(1) +FLAG_FOUND_ROWS(2)
It looks indeed deprecated as in the doc I can't find any reference to FLAG_FIELD_LENGTH
We can thus assume that the flag you really need is FLAG_FOUND_ROWS
According to the doc, the GUI option for this flag is
Return matched rows instead of affected rows
