NAME ^

SQL::Abstract::Query::Update - An object that represents a SQL UPDATE.

SINOPSYS ^

    use SQL::Abstract::Query;
    my $query = SQL::Abstract::Query->new( $dbh );
    
    # Disable all existing customers:
    my ($sql, @bind_values) = $query->update( 'customer', { active => 0 } );
    $dbh->do( $sql, undef, @bind_values );
    
    # Disable all customers in a particular store:
    my ($sql, @bind_values) = $query->update(
        'customer',
        { active => 0 },
        { store_id => $store_id },
    );
    $dbh->do( $sql, undef, @bind_values );
    
    # Use the OO interface to re-use the query and disabled all customers
    # in several stores:
    my $update = $query->update( 'customer', {active=>0}, {store_id=>'id'} );
    my $sth = $dbh->prepare( $update->sql() );
    $sth->execute( $update->values({ id => $store1_id });
    $sth->execute( $update->values({ id => $store2_id });

DESCRIPTION ^

The update query is a very lightweight wrapper around SQL::Abstract's update() method and provides no additional SQL syntax.

Instances of this class should be created using "update" in SQL::Abstract::Query.

This class applies the SQL::Abstract::Query::Statement role.

ARGUMENTS ^

table

See "Table" in SQL::Abstract::Query::Statement.

field_values

See "FieldValues" in SQL::Abstract::Query::Statement.

where

Optional. See "Where" in SQL::Abstract::Query::Statement.
