Description
</title>
<para>
<command>ALTER DOMAIN</command> changes the definition of an existing domain.
There are several sub-forms:
</para>
<variablelist>
<varlistentry>
<term>SET/DROP DEFAULT</term>
<listitem>
<para>
These forms set or remove the default value for a column. Note
that defaults only apply to subsequent <command>INSERT</command>
commands; they do not cause rows already in a table using the domain.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>SET/DROP NOT NULL</term>
<listitem>
<para>
These forms change whether a domain is marked to allow NULL
values or to reject NULL values. You may only <literal>SET NOT NULL</>
when the tables using the domain contain no null values in the domain
based column.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ADD <replaceable class="PARAMETER">domain_constraint</replaceable></term>
<listitem>
<para>
This form adds a new constraint to a table using the same syntax as
<xref linkend="SQL-CREATEDOMAIN" endterm="SQL-CREATEDOMAIN-TITLE">.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>DROP CONSTRAINT</term>
<listitem>
<para>
This form drops constraints on a domain.
</para>
</listitem>
</varlistentry>
</variablelist>
<para>
You must own the domain to use <command>ALTER DOMAIN</>; except for
<command>ALTER TABLE OWNER</>, which may only be executed by a superuser.
</para>
</refsect1>
<refsect1 id="R1-SQL-ALTERDOMAIN-2">
<title>
Usage
</title>
<para>
To add a NOT NULL constraint to a column:
<programlisting>
ALTER DOMAIN zipcode SET NOT NULL;
</programlisting>
To remove a NOT NULL constraint from a column:
<programlisting>
ALTER DOMAIN zipcode DROP NOT NULL;
</programlisting>
</para>
<para>
To add a check constraint to a table:
<programlisting>
ALTER DOMAIN zipcode ADD CONSTRAINT zipchk CHECK (char_length(VALUE) = 5);
</programlisting>
</para>
<para>
To remove a check constraint from a table and all its children:
<programlisting>
ALTER DOMAIN zipcode DROP CONSTRAINT zipchk;
</programlisting>
</para>
