NAME

MySQL::Insert - extended inserts for MySQL via DBI

SYNOPSIS

    # Insert two rows into sample_table using $dbh database handle

    use MySQL::Insert;

    $MySQL::Insert::MAX_ROWS_TO_QUERY = 1000;

    my $inserter = MySQL::Insert->new( $dbh, 'sample_table', [ @field_names ], %param );

    # Param can be:
    # statement = 'INSERT' | 'REPLACE' | 'INSERT IGNORE' (by default)
    # on_duplicate_update = { field_name => field_value, .. } (not used by default)

    # simple insertion
    $inserter->insert_row( { fldname => 'fldvalue1' } );
    $inserter->insert_row( { fldname => 'fldvalue2' } );

    # multirow insertion
    $inserter->insert_row( { fldname => 'fldvalue3' }, { fldname => 'fldvalue4' } );
    $inserter->insert_row( [ 'fldvalue5' ], [ 'fldvalue6' ] } );

    # Insert row into sample_table using $dbh database handle
    # If fldvalue3 is passed as scalar ref then it is not quoted
    # Used to insert MySQL built-in functions like NOW() and NULL values.
    # @field_names must be predefined in case of arrayref row data usage

    $inserter->insert_row( { fldname => \'NOW()' } );

    undef $inserter;

DESCRIPTION

Use multiple-row INSERT syntax that include several VALUES lists. (for example INSERT INTO test VALUES ('1',Some data',2234),('2','Some More Data',23444)). EXTENDED INSERT syntax is more efficient of execution many insert queries. It is not compatible with most RDBMSes.
