          Empress C-API MSCALL   SQL commands may be embedded in a " C" program with the routine  " mscall" . The routine " mscall" takes two   arguments,   the database name and the SQL command. mscall (database_name, sql_command) Both the database name and the SQL command are strings. The strings may be built by the application program. The routine returns zero (0) if the statement succeeds, and a non-zero value if it fails. A failure may be caused by different events such as a syntax error in the SQL command, or an invalid attribute or table name. |
