|
|
you can create a table that includes all of the column definitions from an
|
|
existing table.</p>
|
|
<div class="section"><p>The definitions that are copied are: </p>
|
|
<ul><li>Column names (and system column names)</li>
|
|
<li>Data type, precision, length, and scale</li>
|
|
<li>CCSID</li>
|
|
<li>Column text (LABEL ON)</li>
|

<li>Column heading (LABEL ON)</li>

</ul>

</div>
|
|
<div class="section"><p>If the LIKE clause immediately follows the table name and is not
|
|
enclosed in parenthesis, the following attributes are also included:</p>
|
|
<ul><li>Default value</li>
|
|
<li>Nullability</li>
|
|
</ul>
|
|
<p>If the specified table or view contains an identity column, you must
|
|
specify INCLUDING IDENTITY on the CREATE TABLE statement if you want the identity
|
|
column to exist in the new table. The default behavior for CREATE TABLE is
|
|
EXCLUDING IDENTITY. If the specified table or view is a non-SQL created physical
|
|
file or logical file, any non-SQL attributes are removed.</p>
