I have been assigned a task of migrating mysql++ to postgres by creating a Data Access Layer between the C++ application and the database it is interacting with. I haven't done anything like this ever before so I am totally a novice. These are the exact wordings of my Boss.

"transition of the system from MySQL to postgres, better would be to make the database connection abstract completely, so if a client decides to buy it and connect it to an oracle database, we don't care."

The program currently uses simple queries like:

query << "delete from " << MN << "import";

query << "load data local infile '" << impFile << "' into table " << MN << "import fields terminated by ','";

query << "select count(distinct SLIP), count(distinct SLP_ID) from " << MN << "import";

query << "select TRAD from " << MN << "import where SLIP =" << clslip;





There are no joins etc anywhere involved in the current application and above are the only queries used in the application that are to be converted to postgres.

I am in real trouble .. Please Help me out . i be greatful to you.
regards,
A.Q.Ghouri
