<h1 class="topictitle1">Example 4: Copy from an open query file</h1>
|
|
<div><p>This example shows how to create a copy of the output of a dynamic
|
|
join using the Open Query File (OPNQRYF) and Copy from Query File (CPYFRMQRYF)
|
|
commands.</p>
|
|
<div class="section"><div class="p">Assume that you want to create a physical file that has the format
|
|
and data of the join of FILEA and FILEB, and that the files contain
|
|
the following fields: <pre>FILEA FILEB JOINAB
|
|
Cust Cust Cust
|
|
Name Amt Name
|
|
Addr Amt</pre>
|
|
The join field is Cust, which exists
|
|
in both files. To join the files and save a copy of the results in a new physical
|
|
file MYLIB/FILEC, you can specify: <pre>OPNQRYF FILE(FILEA FILEB) FORMAT(JOINAB) +
|
|
JFLD((FILEA/CUST FILEB/CUST)) +
|
|
MAPFLD((CUST 'FILEA/CUST')) OPNID(QRYFILE)
|
|
CPYFRMQRYF FROMOPNID(QRYFILE) TOFILE(MYLIB/FILEC) CRTFILE(*YES)</pre>
|
|
</div>
|
|
</div>
|
|
<div class="section"><p>The file MYLIB/FILEC will be created by the CPYFRMQRYF command.
|
|
The file will have file attributes like those of FILEA although some file
|
|
attributes might be changed. The format of the file will be like JOINAB. The
|
|
file will contain the data from the join of FILEA and FILEB using the Cust
|
|
field. File FILEC in library MYLIB can be processed like any other physical
|
|
file with control language (CL) commands, such as the Display Physical File
|
|
Member (DSPPFM) command and utilities, such as Query.</p>
