perl-SQL-SplitStatement

This is a simple module which tries to split any SQL code, even including
non-standard extensions (for the details see the the /SUPPORTED DBMSs
manpage section below), into the atomic statements it is composed of.
The logic used to split the SQL code is more sophisticated than a raw
'split' on the ';' (semicolon) character: first, various different
statement terminator tokens are recognized (see below for the list), then
this module is able to correctly handle the presence of said tokens inside
identifiers, values, comments, 'BEGIN ... END' blocks (even nested),
dollar-quoted strings, MySQL custom 'DELIMITER's, procedural code etc.,
as (partially) exemplified in the the /SYNOPSIS manpage above.
Consider however that this is by no means a validating parser (technically
speaking, it's just a context-sensitive tokenizer). It should rather be
seen as an in-progress heuristic approach, which will gradually improve
as test cases will be reported. This also means that, except for the the
/LIMITATIONS manpage detailed below, there is no known (to the author) SQL
code the most current release of this module can't correctly split.
The test suite bundled with the distribution (which now includes the
popular Sakila and Pagila sample db schemata, as detailed in the the
/SHOWCASE manpage section below) should give you an idea of the
capabilities of this module
If your atomic statements are to be fed to a DBMS, you are encouraged to
use the DBIx::MultiStatementDo manpage instead, which uses this module and
also (optionally) offers automatic transactions support, so that you'll
have the all-or-nothing behavior you would probably want.
