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"
