|
||
<div><p>This example shows how to select records using multiple fields
|
||
of the Open Query File (OPNQRYF) command.</p>
|
||
<div class="section"><div class="p">Assume that you want to process all records in which either the <em>Amt</em> field
|
||
is equal to zero, or the <em>Lstdat</em> field (YYMMDD order in character format)
|
||
is equal to or less than 88-12-31. You can specify: <pre>OVRDBF FILE(FILEA) SHARE(*YES)
|
||
OPNQRYF FILE(FILEA) QRYSLT('AMT *EQ 0 *OR LSTDAT +
|
||
*LE "88-12-31" ')
|
||
CALL PGM(PGMC)
|
||
CLOF OPNID(FILEA)
|
||
DLTOVR FILE(FILEA)</pre>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">This example also works if the <em>LSTDAT</em> field has a date
|
||
data type. The <em>LSTDAT</em> field can be in any valid date format; however,
|
||
the job default date format must be YYMMDD and the job default date separator
|
||
must be the dash (–). <div class="note"><span class="notetitle">Note:</span> For any character representation of a date in
|
||
one of the following formats, MMDDYY, DDMMYY, YYMMDD, or Julian, the job default
|
||
date format and separator must be the same to be recognized.</div>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">If variables are used, the QRYSLT parameter is typed as follows: <pre>QRYSLT('AMT *EQ ' *CAT &VARAMT *CAT ' *OR +
|
||
LSTDAT *LE "' *CAT &VARDAT *CAT '"')</pre>
|
||
or, typed in reverse
|
||
order: <pre>QRYSLT('"' *CAT &VARDAT *CAT '" *GT LSTDAT *OR ' +
|
||
*CAT &VARAMT *CAT ' *EQ AMT')</pre>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="note"><span class="notetitle">Note:</span> </div>
|
||
<p>The &VARAMT variable must be defined
|
||
as a character type. If the variable is passed to your control language (CL)
|
||
program as a numeric type, you must convert it to a character type to allow
|
||
concatenation. You can use the Change Variable (CHGVAR) command to do this
|
||
conversion.</p>
