NAME

Alzabo::Runtime::InsertHandle - A handle representing an insert

SYNOPSIS

my $handle =
    $table->insert_handle
        ( columns => [ $table->columns( 'name', 'job' ) ] );

my $faye_row =
    $handle->insert( values =>
                     { name => 'Faye',
                       job => 'HK Pop Chanteuse' } );

my $guesch_row =
    $handle->insert( values =>
                     { name => 'Guesch',
                       job => 'French Chanteuse and Dancer' } );

DESCRIPTION

This object is analogous to a DBI statement handle, and can be used to insert multiple rows into a table more efficiently than repeatedly calling Alzabo::Runtime::Table->insert().

METHODS

Objects of this class provide one public method:

insert

This method is used to insert a new row into a table.

It accepts the following parameters:

• values

  This should be a hash reference containing the values to be inserted into the table.

  If no value is given for a primary key column and the column is "sequenced" then the primary key will be auto-generated.

  If values are not provided for other columns which were given when Alzabo::Runtime::Table->insert_handle was called, this method first checks to see if a value was provided for the column when Alzabo::Runtime::Table->insert_handle was called. If none was provided, then the column's default value is used.

  If column values were passed to Alzabo::Runtime::Table->insert_handle, then these can be overridden by values passed to this method.

  It is not possible to override column values that were given as SQL functions when Alzabo::Runtime::Table->insert_handle was called.

This method returns a new Alzabo::Runtime::Row object.

Throws: Alzabo::Exception::Logic, Alzabo::Exception::Params
