NAME

Teng::Plugin::SearchBySQLAbstractMore - use SQL::Abstract::More as Query Builder for Teng

SYNOPSIS

package MyApp::DB;
use parent qw/Teng/;
__PACKAGE__->load_plugin('SearchBySQLAbstractMore');
__PACAKGE__->sql_abstract_more_new_option(sql_dialect => 'Oracle'); # If you want to pass SQL::Abstract::More new options

package main;
my $db = MyApp::DB->new(dbh => $dbh);

my $itr  = $db->search_by_sql_abstract_more('user' => {type => 3});
my @rows  = $db->search_by_sql_abstract_more('user' => {type => 3}, {rows => 5});

# use pager
my $page = $c->req->param('page') || 1;
my ($rows, $pager) = $db->search_by_sql_abstract_more_with_pager('user' => {type => 3}, {page => $page, rows => 5});

If you want to replace Teng search

package MyApp::DB;
use parent qw/Teng/;
__PACKAGE__->load_plugin('SearchBySQLAbstractMore');
__PACKAGE__->install_sql_abstract_more;
# now, search method is replaced by search_by_sql_abstract_more

If you want to load pager at the same time

# search_with_pager from SearchBySQLAbstractMore::Pager
__PACKAGE__->install_sql_abstract_more(pager => 'Pager');
# search_with_pager from SearchBySQLAbstractMore::Pager::MySQLFoundRows
__PACKAGE__->install_sql_abstract_more(pager => 'Pager::MySQLFoundRows');
# search_with_pager from SearchBySQLAbstractMore::Pager::Count
__PACKAGE__->install_sql_abstract_more(pager => 'Pager::Count');

Create complex SQL using SQL::Abstract::More.

Compatible usage with Teng's search method.

$teng->search_by_sql_abstract_more
   ('table1',
    { name => { like => '%perl%'},
      -and => [
               {x => 1},
               {y => [-or => {'>' => 2}, {'<' => 10}]},
              ],
    },
    {
     from     => ['-join',
                  'table1|t1',
                  't1.id=t2.id',
                  'table2|t2',
                  't1.id=t3.table1_id,t2.id=t3.table2_id',
                  'table3|t3',
                 ],
     columns  => ['x', 'y', 'min(age) as min_age', 'max(age) as max_age'],
     group_by => ['x', 'y'],
     having   => {'max_age' => {'<' => 10}},
    },
   );
# SELECT x, y, min(age) as min_age, max(age) as max_age
#   FROM table1 AS t1
#     INNER JOIN table2 AS t2 ON ( t1.id = t2.id )
#     INNER JOIN table3 AS t3 ON ( ( t1.id = t3.table1_id AND t2.id = t3.table2_id ) )
#   WHERE ( ( ( x = ? AND ( y > ? OR y < ? ) ) AND name LIKE ? ) )
#   GROUP BY x, y  HAVING ( max_age < ? );

SQL::Abstract::More original usage(as first argument, use hash ref instead of table name):

$teng->search_by_sql_abstract_more(
  {
    -columns  => ['x', 'y', 'min(age) as min_age', 'max(age) as max_age'],
    -from     => [-join,
                  'table1|t1',
                  't1.id=t2.id',
                  'table2|t2',
                  't1.id=t3.table1_id,t2.id=t3.table2_id',
                  'table3|t3',
                ],
    -group_by => ['x', 'y'],
    -having   => {'max_age' => {'<' => 10'}},
    -where => {
       name => { like => '%perl%'},
       -and => [
           {x => 1},
           {y => [-or => {'>' => 2}, {'<' => 10}]},
       ],
     },
  },
);
# SQL is as same as the avobe code.

Using pager.

Compatible usage:

$teng->search_by_sql_abstract_more(
  'table', {
    name => 1,
    age  => 10,
  },
  {
    -columns  => ['x', 'y'],
    -from     => ['table'],
    -page     => 2,
    -rows     => 20,
  },
);

Originaly usage:

$teng->search_by_sql_abstract_more(
  {
    -columns  => ['x', 'y'],
    -from     => ['table'],
    -where    => {
         name => 1,
         age  => 10,
    },
    -page     => 2,
    -rows     => 20,
  },
);

Generate SQL by SQLAbstractMore

($sql, @binds) = $teng->create_sql_by_sql_abstract_more($table, $where, $opt);

It returns SQL and bind values with same args of search_bys_sql_abstract_more method.

METHODS

search_by_sql_abstract_more

see SYNOPSIS.

create_sql_by_sql_abstract_more

($sql, @binds) = $teng->create_sql_by_sql_abstract_more($table, $where, $opt);

This method returns SQL statement and its bind values. It doesn't check table is in schema.

CLASS METHOD

sql_abstract_more_instance

YourClass->sql_abstract_more_instance;

return SQL::Abstract::More object.

sql_abstract_more_new_option

YourClass->sql_abstract_more_new_option(sql_dialect => 'Oracle');

This method's arguments are passed to SQL::Abstract::More->new(). see SQL::Abstract::More new options.

If you want to replace search method of original Teng, call this.

Teng::Plugin::SearchBySQLAbstractMore->replace_teng_search;

It is useful when you wrap search method in your module and call Teng's search method in it and you want to use same usage with SQL::Abstract::More.

install_sql_abstract_more

package YourClass;
use Teng::Plugin::SearchBySQLAbstract::More; # no need to use ->load_plugin();

YourClass->install_sql_abstract_more; # search_sql_abstract_more is defined as YourClass::search
YourClass->install_sql_abstract_more(alias => 1); # same as the above

YourClass->install_sql_abstract_more(replace => 1); # Teng::Search is replaced by search_sql_abstract_more

YourClass->install_sql_abstract_more(alias => 'complex_search');
# sql_abstract_more is defined as YourClass::complex_search

YourClass->install_sql_abstract_more(alias => 'complex_search', pager => 1);
# sql_abstract_more is defined as YourClass::complex_search
# sql_abstract_more_pager is defined as YourClass::complex_search_with_pager

YourClass->install_sql_abstract_more(alias => 'complex_search', pager => 1, pager_alias => 'complex_search_paged');
# sql_abstract_more is defined as YourClass::complex_search
# sql_abstract_more_pager is defined as YourClass::complex_search_paged

# use different pager
YourClass->install_sql_abstract_more(pager => 1); # or pager => 'simple' / 'Pager'
YourClass->install_sql_abstract_more(pager => 'mysql_found_rows'); # or pager => 'Pager::MySQL::FoundRows'
YourClass->install_sql_abstract_more(pager => 'count'); # or pager => 'Pager::Count'

It call replace_teng_search if replace option is passed and it is true and loads pager plugin with alias option if pager option is true. search and search_with_pager are installed to your class.

This method can take the following options.

replace

If you want to replace Teng's search method, pass this option.

YourClass->install_sql_abstract_more(replace => 1);

alias

YourClass->install_sql_abstract_more(alias => 'complex_search');
YourClass->install_sql_abstract_more(pager => 'Pager', alias => 'complex_search');

This is equals to:

YourClass->load_plugin('Teng::Plugin::SearchBySQLAbstractMore', {
   alias => 'search_by_sql_abstract_more' => 'complex_search',
});
YourClass->load_plugin('Teng::Plugin::SearchBySQLAbstractMore::Pager', {
   alias => 'search_by_sql_abstract_more_with_pager' => 'complex_search_with_pager',
});

pager_alias

If you want to use different alias for pager search.

YourClass->install_sql_abstract_more(pager => 'Pager', pager_alias => 'complex_search_with_pager');

This is equals to:

YourClass->load_plugin('Teng::Plugin::SearchBySQLAbstractMore', {
   alias => 'search_by_sql_abstract_more' => 'search',
});
YourClass->load_plugin('Teng::Plugin::SearchBySQLAbstractMore::Pager', {
   alias => 'search_by_sql_abstract_more_with_pager' => 'complex_search_with_pager',
});

pager

Pass pager plugin name or 1.

YourClass->install_sql_abstract_more(pager => 1);       # load SearchBySQLAbstractMore::Pager
YourClass->install_sql_abstract_more(pager => 'Pager'); # same as the above
YourClass->install_sql_abstract_more(pager => 'simple'); # same as the above

YourClass->install_sql_abstract_more(pager => 'Pager::MySQLFoundRows');# load SearchBySQLAbstractMore::Pager::MySQLFoundRows
YourClass->install_sql_abstract_more(pager => 'mysql_found_rows');          # same as the above

YourClass->install_sql_abstract_more(pager => 'Pager::Count'); # load SearchBySQLAbstractMore::Pager::Count
YourClass->install_sql_abstract_more(pager => 'count');  # same as the above
