SQLParser

SQL-Parser

Why?

Sometimes we need to parse and validate SQL.

What does it do?

It parse SQL (mostly MySQL's SQL) and exposes the SQL query as an object so it can be manipulated and assembled back to a query.

How to install?

composer install crodas/sql-parser

How to use it?

require __DIR__ . "/vendor/autoload.php";

$parser = new SQLParser;
$queries = $parser->parse("SELECT * FROM table1 WHERE id = :id");
var_dump(get_class($queries[0])); // string(16) "SQLParser\Select"
var_dump($queries[0]->getTable()[0]->getValue()); // string(6) "table1"
/*
 array(1) {
   [0] =>
   string(2) "id"
   }
*/
var_dump($queries[0]->getVariables()); 

// SELECT * FROM 'table1' WHERE 'id' = :id
echo $queries[0] . "\n";

SQLParser\Writer\SQL::setInstance(new SQLParser\Writer\MySQL);

// SELECT * FROM `table1` WHERE `id` = :id
echo $queries[0] . "\n";

TODO:

1. Better documentation
2. Fluent-Interface to generate SQL statements and alter the parsed content
3. parse CREATE TABLE/ALTER TABLE (for SQLite, MySQL and PostgreSQL flavors)
