DESCRIPTION

This package provides methods for converting json-sql data structures into SQLite statements.

INHERITS

This package inherits behaviors from:

SQL::Engine::Grammar

LIBRARIES

This package uses type constraints from:

Types::Standard

METHODS

This package implements the following methods:

column_change

column_change(HashRef $data) : Object

The column_change method generates SQL statements to change a column definition.

column_change example #1

my $grammar = SQL::Engine::Grammar::Sqlite->new(
  schema => {
    'column-change' => {
      for => {
        table => 'users'
      },
      column => {
        name => 'accessed',
        type => 'datetime',
        nullable => 1
      }
    }
  }
);

$grammar->column_change($grammar->schema->{'column-change'});

transaction

transaction(HashRef $data) : Object

The transaction method generates SQL statements to commit an atomic database transaction.

transaction example #1

my $grammar = SQL::Engine::Grammar::Sqlite->new(
  schema => {
    'transaction' => {
      queries => [
        {
          'table-create' => {
            name => 'users',
            columns => [
              {
                name => 'id',
                type => 'integer',
                primary => 1
              }
            ]
