DBSchema::ColGroup(3pm) User Contributed Perl Documentation DBSchema::ColGroup(3pm) NAME
DBIx::DBSchema::ColGroup - Column group objects SYNOPSIS
use DBIx::DBSchema::ColGroup; $colgroup = new DBIx::DBSchema::ColGroup ( $lol_ref ); $colgroup = new DBIx::DBSchema::ColGroup ( @lol ); $colgroup = new DBIx::DBSchema::ColGroup ( [ [ 'single_column' ], [ 'multiple_columns', 'another_column', ], ] ); $lol_ref = $colgroup->lol_ref; @sql_lists = $colgroup->sql_list; @singles = $colgroup->singles; DESCRIPTION
This class is deprecated and included for backwards-compatibility only. See DBIx::DBSchema::Index for the current class used to store unique and non-unique indices. DBIx::DBSchema::ColGroup objects represent sets of sets of columns. (IOW a "list of lists" - see perllol.) METHODS
new [ LOL_REF ] Creates a new DBIx::DBSchema::ColGroup object. Pass a reference to a list of lists of column names. lol_ref Returns a reference to a list of lists of column names. sql_list Returns a flat list of comma-separated values, for SQL statements. For example: @lol = ( [ 'single_column' ], [ 'multiple_columns', 'another_column', ], ); $colgroup = new DBIx::DBSchema::ColGroup ( @lol ); print join(" ", $colgroup->sql_list), " "; Will print: single_column multiple_columns, another_column singles Returns a flat list of all single item lists.
