NAME

CXC::DB::DDL::Table - CXC::DB::DDL Table class

VERSION

version 0.18

OBJECT ATTRIBUTES

name

The table name

schema

The schema that the table is in. If not specified, The "name" attribute is scanned for the schema, under the assumption that the form is

<schema>.<table name>

temporary

true if the table should be created as a temporary table

indexes

The list of table indexes

constraints

One or more table constraints, either as a single constraint or an array of constraints.

The constraints must meet the "Constraint" in CXC::DB::DDL::Types type.

If the constraint attribute expression is a coderef, it is called as

$expression->( $dbh, $sqlt, $constraint )

where $dbh is DBI handle, $sqlt is the SQL::Translator object, and must return a scalar containing the final expression. This is typically used to ensure that identifiers are properly quoted. See "quote" in DBI and "quote_identifier" in DBI.

$dbh, $sqlt and $constraint must not be changed.

checks

DEPRECATED; add an entry to "constraints" with fields

type => CHECK_C, expression => $expr

The list of table check constraints

fields

The list of fields
