<div><p>This example shows how to select records using the contains function
|
||
|
|
of the Open Query File (OPNQRYF) command.</p>
|
||
|
|
<div class="section"><div class="p">Assume that you want to process all records in which the <em>Addr</em> field
|
||
|
|
contains the street named BROADWAY. The contains (*CT) function determines
|
||
|
|
if the characters appear anywhere in the named field. You can specify as follows: <pre>OVRDBF FILE(FILEA) SHARE(*YES)
|
||
|
|
OPNQRYF FILE(FILEA) QRYSLT('ADDR *CT "BROADWAY" ')
|
||
|
|
CALL PGM(PGMC)

</div>
|
||
|
|
<div class="section"><div class="p">In this example, assume that the data is in uppercase in the database
|
||
|
|
record. If the data is in lowercase or mixed case, you can specify
|
||
|
|
a translation function to translate the lowercase or mixed case data to uppercase
|
||
|
|
before the comparison is made. The system-provided table QSYSTRNTBL translates
|
||
|
|
the letters a through z to uppercase. (You can use any translation table to
|
||
|
|
perform the translation.) Therefore, you can specify as follows: <pre>OVRDBF FILE(FILEA) SHARE(*YES)
|
||
|
|
OPNQRYF FILE(FILEA) QRYSLT('%XLATE(ADDR QSYSTRNTBL) *CT +
|
||

"BROADWAY" ')

|

<div class="section"><p>When the %XLATE function is used on the QRYSLT statement, the
|
||
|
|
value of the field passed to the high-level language program appears as it
|
||
|
|
is in the database. You can force the field to appear in uppercase using the
|

|

%XLATE function on the MAPFLD parameter.</p>
