DB

Datasource loading resource. This resource allows you to load the datasource that suits you best, supports connection to MariaDB, MSSQLServer, PostgreSQL, H2 and Oracle.

// Be careful when entering parameters in queries,
// you must not use the string concatenation
// to ensure security against SQL Injection as it follows:

const NOK = _db.query(
  'select * from client where id = '+ _req.getString('id')
);

// WARNING: The above example is incorrect.
// Follow the pattern below to ensure safety
// when injecting parameters:

const OK = _db.query(
  'select * from client where id = ?', _val.list().add( _req.getString('id') )
);
