<div><p>This example illustrates how to select records from a table based on the current date.</p>
|

|
|
<div class="p"><pre>Create Table TestDate (
|
||
|
|
PKCol Int Primary Key,
|
||
|
|
DecDate Decimal( 9,0 ),
|
||
|
|
CharDate Char( 8 ) )
|
||
|
|
|
||
|
|
Insert Into TestDate Values ( 1, 20010711, '20010711' )</pre>
|
||
|
|
</div>
|
||
|
|
<div class="p">Use this SQL statement to compare against the numeric field:<pre>Select *
|
||
|
|
From TestDate
|
||
|
|
Where DecDate =
|
||
|
|
100 * ( 100 * Year( CurDate() ) + Month( CurDate() ) ) +
|
||
|
|
Day( CurDate() )</pre>
|
||
|
|
</div>
|
||
|
|
<div class="p">Using a <tt>Cast</tt> expression, you can convert this 8-digit number to a character value, as in the following example:<pre>Select *
|
||
|
|
From TestDate
|
||
|
|
Where CharDate = Cast(
|
||
|
|
100 * ( 100 * Year( CurDate() ) + Month( CurDate() ) ) +
|
||
|
|
Day( CurDate() ) As Char( 8 ) )</pre>
|
||
|
|
</div>
|
||
|
|
<p>Use care when converting a Month() or Day() return value to a character with <tt>Cast</tt>. If you do not explicitly handle values less than 10, there might be spaces instead of zeros in the result.</p>
