    Hey guys I want to insert values into a MySql database. The following line works fine:

    mysql_query(connection, "INSERT INTO main (NumofShows , Title) VALUES('12', 'Home')");

    but if the data to be inserted is from a string... like....

    string NewTitle = "Monaco";
    string NumofShows = "2";

    What can i do so it will be able to read the strings and use their values to be inserted into the data table?

      CString.Format can help in this!

            mysql_query(connection, "INSERT INTO main (NumofShows , Title) VALUES('12', 'Home')")

            Sorry i think you misunderstood what i meant. Normally, for the values, it has to be hardcoded in, for example, having to put 12 and home inside. What i meant is, for example, if the values to be inserted are in a variable , like .. string NewShowName = "Danger" int NewNumberofShow = "2" How do i put in this variables (NewShowName, NewNumberofShow) into the sql statements at VALUES so the program can read the values inside this variables and then save them in the database

              Might I suggest you will probably get a better response in the Database forum for this question.

                If you are using MFC, try:

                CString strQuery;
                strQuery.Format("INSERT INTO main (NumofShows , Title) VALUES('%d', '%s')", number, title);

                If not, you can use the same format with sprintf();
