The SQL preprocessor is an executable named sqlpp.exe.
The SQLPP command line is as follows:
sqlpp [ options ] sql-filename [output-filename]
The SQL preprocessor processes a C program with embedded SQL before the C or C++ compiler is run. The preprocessor translates the SQL statements into C/C++ language source that is put into the output file. The normal extension for source programs with embedded SQL is .sqc. The default output file name is the sql-filename with an extension of .c. If the sql-filename already has a .c extension, then the output file name extension is .cc by default.
For a full listing of the command line options, see SQL preprocessor.
