|
||
<div><p>This example shows how to specify the complex selection statements
|
||
when you select records using the Open Query File (OPNQRYF) command.</p>
|
||
<div class="section"><div class="p">Complex selection statements can also be specified. For example,
|
||
you can specify: <pre>QRYSLT('DATE *EQ "880101" *AND AMT *GT 5000.00')
|
||
|
||
QRYSLT('DATE *EQ "880101" *OR AMT *GT 5000.00')</pre>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">You can also specify: <pre>QRYSLT('CODE *EQ "A" *AND TYPE *EQ "X" *OR CODE *EQ "B")</pre>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">The rules governing the priority of processing the operators are
|
||
described in the Control language (CL) topic. Some of the rules are: <ul><li>The *AND operations are processed first; therefore, the record would be
|
||
selected if: <div class="p"> <p> The <em>Code</em> field = "A" and The <em>Type</em> field = "X"<br />
|
||
or<br />
|
||
The <em>Code</em> field = "B"</p>
|
||
</div>
|
||
</li>
|
||
<li>Parentheses can be used to control how the expression is handled, as shown
|
||
in this example: <pre>QRYSLT('(CODE *EQ "A" *OR CODE *EQ "B") *AND TYPE *EQ "X" +
|
||
*OR CODE *EQ "C"')</pre>
|
||
<div class="p"> <p> The <em>Code</em> field = "A" and The <em>Type</em> field= "X"<br />
|
||
or<br />
|
||
The <em>Code</em> field = "B" and The <em>Type</em> field = "X"<br />
|
||
or<br />
|
||
The <em>Code</em> field = "C"</p>
|
||
</div>
|
||
</li>
|
||
</ul>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">You can also use the symbols described in the Control language
|
||
(CL) topic, instead of the abbreviated form (for example, you can use = instead
|
||
of *EQ), as shown in this example: <pre>QRYSLT('CODE = "A" & TYPE = "X" | AMT > 5000.00')</pre>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">This command selects all records in which: <p> The <em>Code</em> field = "A" and The <em>Type</em> field = "X"<br />
|
||
or<br />
|
||
The <em>Amt</em> field > 5000.00</p>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">A complex selection statement can also be written like this:<pre>QRYSLT('CUSNBR = %RANGE("60000" "69999") & TYPE = "B" +
|
||
& SALES>0 & ACCRCV / SALES>.3')</pre>
|
||
</div>
|
||
</div>
|
||
<div class="section"><div class="p">This command selects all records in which: <p> The <em>Cusnbr</em> field is in the range 60000-69999 and<br />
|
||
The <em>Type</em> field = "B" and<br />
|
||
The <em>Sales</em> fields are greater than 0 and<br />
|
||
<em>Accrcv</em> divided by <em>Sales</em> is greater than 30 percent</p>
