guys,</SPAN></FONT> <o:p></o:p></P>
<P><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">A
work colleague of mine is having problems with SQL cursors. She is using a
simple SELECT but with a WHERE clause saying DATE_PROCESSED is NULL. Her query
does not return anything.</SPAN></FONT><o:p></o:p></P>
<P><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The
database is Oracle. I was wondering how would one interrogate Oracle databases
using PH CURSORS, where you want to check a date column that is
blank?</SPAN></FONT><o:p></o:p></P>
<P><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">She
tried DATE_PROCESSED = 0 but the parser rejects this as an invalid logical
construct. We want to check for ZERO but it looks like we may need to convert
the 0 (CAST it) to a date type and not (I assume) a native INTEGER type. Of
course if she uses DATE_CONVERT IS NULL the parser accepts this, but we know
none of the rows have an actual NULL value.</SPAN></FONT><o:p></o:p></P>
<P><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">In
PL/SQL, we physically removed a date value from the column and then used QUIZ to
see if it stored the "empty" field as a NULL. We found out using a "DEFINE a = 1
if DATE_PROCESSED is NULL else 0" came back 0 and not
1.</SPAN></FONT><o:p></o:p></P>
