DESCRIPTION

The purpose of this module is to generate SQL Query. General queries has covered insert, delete, update, select, and select with join - (select_join). And the additional query has covered to create table.

METHODS

CellBIS::SQL::Abstract inherits all methods from Mojo::Base. General methods available for insert, update, select, and select_join.

For additional method, only available for create_table. Currently, only supports MariaDB/MySQL and SQLite Syntax

The following are the methods available from this module:

create_table - SQLite

use CellBIS::SQL::Abstract

my $sql_abstract = CellBIS::SQL::Abstract->new(db_type => 'sqlite');

my $table_name = 'my_users';
my $col_list = [ 'id', 'first_name', 'last_name', 'other_col_name' ];
my $col_attr = {
  'id'             => {
    type          => { name => 'integer' },
    is_primarykey => 1,
    is_autoincre  => 1,
  },
  'first_name'     => {
    type    => {
      name => 'varchar',
      size => 50,
    },
    is_null => 0,
  },
  'last_name'      => {
    type    => {
      name => 'varchar',
      size => 50,
    },
    is_null => 0,
  },
  'other_col_name' => {
    type    => {
      name => 'varchar',
      size => 60,
    },
    is_null => 0,
  }
};
$create_table = $sql_abstract->create_table($table_name, $col_list, $col_attr);

SQL equivalent :

CREATE TABLE IF NOT EXISTS users(
    id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
    first_name VARCHAR NOT NULL,
    last_name VARCHAR NOT NULL,
    other_col_name VARCHAR(60) NOT NULL
)

create_table - MariaDB/MySQL

use CellBIS::SQL::Abstract

my $sql_abstract = CellBIS::SQL::Abstract->new(db_type => 'mariadb');

my $table_name = 'my_users';
my $col_list = [ 'id', 'first_name', 'last_name', 'other_col_name' ];
my $col_attr = {
  'id'             => {
    type          => {
      name => 'int',
      size => 11
    },
    is_primarykey => 1,
    is_autoincre  => 1,
  },
  'first_name'     => {
    type    => {
      name => 'varchar',
      size => 50,
    },
    is_null => 0,
  },
  'last_name'      => {
    type    => {
      name => 'varchar',
      size => 50,
    },
    is_null => 0,
  },
  'other_col_name' => {
    type    => {
      name => 'varchar',
      size => 60,
    },
    is_null => 0,
  }
};
$create_table = $sql_abstract->create_table($table_name, $col_list, $col_attr);

SQL equivalent :

CREATE TABLE IF NOT EXISTS users(
    id INT(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    other_col_name VARCHAR(60) NOT NULL

    },
    is_null => 0,
  }
};
$create_table = $sql_abstract->create_table($table_name, $col_list, $col_attr);
