NAME
Teng::Plugin::SearchBySQLAbstractMore - use SQL::Abstract::More as Query Builder for Teng
VERSION
Version 0.07
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 teble 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 satement 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 passded to SQL::Abstract::More->new(). see SQL::Abstract::More new options.
replace_teng_search
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
