<h1 class="topictitle1">Specify *UPDADD when copying files</h1>
|
|
<div><p>When you specify *UPDADD on the CPYF command, a from-file key value
|
|
builds before the from-file record moves into the to-file. The from-file builds
|
|
this key value by using the key specifications of the to-file.</p>
|
|
<p>Before the key value is built, the server performs any necessary field
|
|
or data mapping, data conversion, or record selection. The server checks the
|
|
to-file to see if this key value already exists in it (duplicate key of the
|
|
from-file data). If the key value does exist in the to-file, the from-file
|
|
record that contains the key value updates that to-file record.</p>
|
|
<div class="p">The following rules apply if you specify MBROPT(*UPDADD) on
|
|
the <a href="../cl/cpyf.htm">CPYF</a> command: <ul><li>The to-file must be a local database physical file that contains a primary
|
|
or unique key.</li>
|
|
<li>You cannot specify CRTFILE(*YES). The to-file must exist before you run
|
|
CPYF.</li>
|
|
<li>CPYF cannot copy from multiple formats.</li>
|
|
<li>Detected duplicate keys are not skipped but updated with the new from-file
|
|
record value. Duplicate key errors (CPF5026) are not included as ERRLVL errors.</li>
|
|
<li>CPF5027 will be included as an ERRLVL error. This error can occur if another
|
|
process has a record that is locked. To avoid this error, you might want to
|
|
pre-allocate the to-file within your job before performing the CPYF. You can
|
|
use the WAITRCD parameter on the <a href="../cl/crtpf.htm">CRTPF</a> and <a href="../cl/chgpf.htm">CHGPF</a> commands to limit the length of time that the commands
|
|
spend waiting for a record lock to be released in the to-file.</li>
|
|
<li>All existing FMTOPT values are allowed. However, when using MBROPT(*UPDADD),
|
|
take care to avoid updating records that you do not want to update. Also avoid
|
|
updating the same record multiple times when it is not what you want.</li>
|
|
<li>Nulls are not used in determining duplicate key values if FMTOPT(*NOCHK)
|
|
is specified or if the from-file is a device file.</li>
|
|
<li>You must have the minimum following authorities to the to-file: <ul><li>Object operational (*OBJOPR)</li>
|
|
<li>Add (*ADD)</li>
|
|
<li>Update (*UPD)</li>
|
|
</ul>
|
|
</li>
