Re: Sqlpassthru error after update to Mysql 8

Hi Harry,

Unfortunately, I don't have Visual Foxpro to test how it works with your program.
However, there are a few things to check.

First of all, the ODBC Driver does not support named parameters such as ?Param_1, ?Param_2 etc.
The parameters placeholders have to be unnamed:

SqlCommand="Select * from Table_a where Key1=? and Key2=?"

On the other hand, Foxpro can do some additional processing for the parameters... So, at the end it might send the queries with the "?" for the parameter placeholder.

Another thing to check is to enable preparing statements on the client.
In MySQL ODBC GUI dialog tick [Details >> Misc >> [x] Prepare statements on the client]

Hope this helps.
