## Simple ORM via HTTP-RDBMS

• supports parameters (resolve for SQL injection)
• supports schema builder
• supports query builder
• supports order builder
• supports paging

var builders = new requiere('partial.js/builders');
var rdbms = new requiere('partial.js/rdbms');
 
var db = new rdbms.SQLServer('http://myrdbms/sqlserver/', 'Data Source=;Database=;Uid=;Pwd=;');
 
// or
 
var db = new rdbms.MySQL('http://myrdbms/mysql/', 'Server=;Database=;Uid=;Pwd=;');
 
builders.schema('tbl_user', {
    Id: 'int',
    FirstName: 'string(50)',
    LastName: 'string(50)',
    Age: 'int'
}, 'Id');
 
var newUser = {
    FirstName: 'Peter',
    LastName: 'Sirka',
    Age: 28
};
 
db.insert('tbl_user', newUser, function(data) {
 
    console.log(data.Id);
    db.delete('tbl_user', newUser);
 
});
 
var where = new builders.QueryBuilder();
var order = new builders.OrderBuilder();
 
order.asc('Id').desc('FistName');
where.addValue('Id', '>', 10).addOperator('AND').addValue('FistName', '=', 'Peter');
// Query:
// SQL Server: Id > @a AND FirstName = @b
// MySQL: Id > ? AND FirstName = ?
 
db.findTop(10, 'tbl_user', where, order, function(data) {
    console.log(data);
});
 
db.execute('UPDATE tbl_user SET Price=20 WHERE Id BETWEEN {a} AND {b}', { a: 10, b: 20 });
// Query:
// SQL Server: UPDATE tbl_user SET Price=20 WHERE Id BETWEEN @a AND @b
// MySQL: UPDATE tbl_user SET Price=20 WHERE Id BETWEEN ? AND ?
 
db.scalar('SELECT COUNT(*) FROM tbl_user', null, null, function(err, data) {
    console.log(data);
});
 
// multiple recordset
db.reader('SELECT Id, LastName FORM tbl_user; SELECT Id, FirstName FROM tbl_user', function(err, data) {
    // data[0] == []
    // data[1] == []
});
 
db.count('tbl_user', function(err, data) {
    // data.value
});
 
db.count('tbl_user', where, function(err, data) {
    // data.value
