RE: get instance variable
Hi Robert - The only way I have found to get this sort of stuff (as well as security info) out is to use mysql_query (or mysql_real_query) and issue the query just like you would at the mysql client. Then you can interpret the results that are returned. I am having to do that with column level grants by user ID to implement views of the data in a C++ environment and it's the only way that I could find to do it. There are not a lot of C API things that are specific to getting data column metadata and other configuration data. IT is mostly for obtaining connections, results sets, and manipulating result sets. It appears that the way they want you to get stuff out using the C API is not with lots of specific calls, but by just issuing the command yourself and interpreting the result set. I found the best way is to write a simple program to issue a call and the cout the result set information. Be sure and do that because sometimes the returned data will surprise you a little bit I have some working C++ connection and result set classes if you would like them, plus a test program you can use.
