Methods

select

# Usage 1: string parameter

$db->select('title, content')->table('test')->getAll();
# Output: "SELECT title, content FROM test"

$db->select('title AS t, content AS c')->table('test')->getAll();
# Output: "SELECT title AS t, content AS c FROM test"

# Usage2: array parameter

$db->select(['title', 'content'])->table('test')->getAll();
# Output: "SELECT title, content FROM test"

$db->select(['title AS t', 'content AS c'])->table('test')->getAll();
# Output: "SELECT title AS t, content AS c FROM test"

select functions (min, max, sum, avg, count)

# Usage 1:

$db->table('test')->max('price')->get();
# Output: "SELECT MAX(price) FROM test"

# Usage 2:

$db->table('test')->count('id', 'total_row')->get();
# Output: "SELECT COUNT(id) AS total_row FROM test"

table

### Usage 1: string parameter

$db->table('table');
# Output: "SELECT * FROM table"

$db->table('table1, table2');
# Output: "SELECT * FROM table1, table2"

$db->table('table1 AS t1, table2 AS t2');
# Output: "SELECT * FROM table1 AS t1, table2 AS t2"

### Usage 2: array parameter

$db->table(['table1', 'table2']);
# Output: "SELECT * FROM table1, table2"

$db->table(['table1 AS t1', 'table2 AS t2']);
# Output: "SELECT * FROM table1 AS t1, table2 AS t2"

get AND getAll

# get(): return 1 record.
# getAll(): return multiple records.

$db->table('test')->getAll();
# Output: "SELECT * FROM test"

$db->select('username')->table('users')->where('status', 1)->getAll();
# Output: "SELECT username FROM users WHERE status='1'"

$db->select('title')->table('pages')->where('id', 17)->get();
# Output: "SELECT title FROM pages WHERE id='17' LIMIT 1"

join

$db->table('test as t')->join('foo as f', 't.id', 'f.t_id')->where('t.status', 1)->getAll();
# Output: "SELECT * FROM test as t JOIN foo as f ON t.id=f.t_id WHERE t.status='1'"

You can use this method in 7 ways. These;
