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

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.
search_bys_sql_abstract_more
see SYNOPSIS.
This method returns SQL statement and its bind values. It doesn't check table is in schema.
YourClass->sql_abstract_more_instance;
return SQL::Abstract::More object.
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.
search
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.
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.
search_with_pager
This method can take the following options.
If you want to replace Teng's search method, pass this option.
YourClass->install_sql_abstract_more(replace => 1);
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', });
If you want to use different alias for pager search.
YourClass->install_sql_abstract_more(pager => 'Pager', pager_alias => 'complex_search_with_pager');
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', });
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
