<h1 class="topictitle1">How the copy function adds members to the to-file</h1>
|
|
<div><p>The copy function adds a member to the to-file when the member
|
|
does not exist. The member name used is either the TOMBR parameter value from
|
|
the copy command, or the member name that is specified in an override for
|
|
the to-file.</p>
|
|
<p>If TOMBR(*FROMMBR) or TOMBR(*FROMLABEL) is specified on the copy command
|
|
(and is not overridden), the from-file member names or label identifiers are
|
|
used for the members added to the file.</p>
|
|
<div class="p">If TOMBR(*FIRST) is specified on the copy command, or if there is an override
|
|
that specifies a TOFILE parameter with no MBR parameter, then no member name
|
|
is known. The copy function does not add a member in this case unless the
|
|
following conditions are true: <ul><li>You specified CRTFILE(*YES) on the copy command</li>
|
|
<li>The copy function must create the to-file</li>
|
|
</ul>
|
|
</div>
|
|
<p>Except for the CPYFRMQRYF command, when the copy function creates the to-file
|
|
without a specific member name specified, the from-file name is used for the
|
|
member that is added to the to-file. When using the CPYFRMQRYF command, the
|
|
member added to the physical file that is created by the copy operation has
|
|
the name specified by the TOMBR parameter. If you specify TOMBR(*FIRST), the
|
|
to-file member has the same name as the to-file file name that is specified
|
|
on the TOFILE parameter of the CPYFRMQRYF command. The copy command ignores
|
|
the MBROPT parameter value when it creates the to-file, and adds records to
|
|
the new file members.</p>
|
|
<p>If the from-file is a database file, the copy command uses the member text
|
|
and SEU source type of the from-file member for the member that is added to
|
|
the to-file. If the from-file is a device or inline data file, the copy command
|
|
takes the text from message CPX0411; the SEU source type is TXT. If both the
|
|
from-file and to-file are database source files, the SEU source type information
|
|
in the added member will be the same as the from-file member. When it adds
|
|
the to-file member, the copy command always assigns the SHARE(*NO) and EXPDATE(*NONE)
|
|
attributes to the to-file member. The copy command also sets the creation
|
|
date of the new member to the current system date (not the date when the from-file
|
|
member was added).</p>
|
|
<p>When the copy command adds a member to a to-file that is a parent file,
|
|
the constraint becomes established at that time.</p>
