<div class="section"><p>The file, library, and file member names used by ODP are the same
|
||
|
|
as the first file and file member names specified on the FILE parameter, unless
|
||
|
|
an override forces the use of a different file or file member name. The record
|
||
|
|
format name of the open query file is the same as that specified on the FORMAT
|
||
|
|
parameter. </p>
|
||
|
|
<p>The Open Query File (OPNQRYF) command always opens a file
|
||
|
|
with an ODP that is shared, as if SHARE(*YES) were specified for the file.
|
||
|
|
If the file, library, or file member name specified in the high-level language
|
||
|
|
(HLL) program differs from the name of the open query file, an override command
|
||
|
|
must be used to specify the correct file, library, and member names to allow
|
||
|
|
the HLL program to share the open query file ODP. If the first, or the only,
|
||
|
|
member queried has an attribute of SHARE(*NO), SHARE(*YES) must be specified
|
||
|
|
in an override to enable an HLL program to share the query file ODP.</p>
|
||
|
|
<p>If
|
||
|
|
the OPNQRYF command is scoped to the job, any subsequent open, other than
|
||
|
|
a query open, of the same file can share the ODP whether scoped to an activation
|
||
|
|
group or the job. If the OPNQRYF command is scoped to an activation group,
|
||
|
|
any subsequent open, other than a query open, of the same file can share the
|
||
|
|
ODP if it is also scoped to the same activation group.</p>
