# Parse SQL

my $input = 'select * from myTable;';
my $obj = MarpaX::Languages::SQL2003::AST->new(host => 'C');
my $ast = $obj->parse($input);
my $xml = $obj->parse($input, xml => 1);This module translates SQL-2003 to an AST.
Instantiate a new object. %opts supported keys are:
- host
-
Target host language. Supported values are: Ada, C, Cobol, Fortran, Mumps, Pascal, PLI. Default value C.
Parse $input and return $self. Accept an optional %opts hash whose keys can be:
- xml
-
If $opts{xml} is a true value, produces the AST as an XML::LibXML::Document object. Default is a false value, meaning that the AST is a composite structure of blessed hash references and array references.
Any other key will be passed as-is to the Marpa's parse() method, i.e. it has to have a meaning to Marpa's recognizer. Typical examples are: trace_terminals => 1, trace_values => 1.
Alias to $self->parse($input, xml => 1, %opts).

This module is using a generated Marpa::R2's BNF grammar, based on a manipulation of http://savage.net.au/SQL/sql-2003-2.bnf, the later being in EBNF format. That is, some rules or lexemes in the output may appear as Genxxx or GenLexyyy, showing unfortunately some of the internals of the EBNF to BNF transformation.
