SQLTeX is a pre-processor that enables the use of SQL statements in LaTeX. The SQLTeX Perl script reads an input file containing the LaTeX source with SQL commands, and writes a LaTeX file in which the SQL commands have been replaced by the values from their execution. It is possible to select a field for substitution in your LaTeX document, or to be used as input in another SQL command. The default is to use MySQL databases, but Pg, Sybase, Oracle, Ingres, mSQL and PostgreSQL are also supported.
