Actually depending on how you write the statement you do not have to explicitly convert the date to character first in order to concatenate it to a character constant.
UT1 > l
1* select 'DATE: '|| trunc(sysdate - 1) from dual
UT1 > /
'DATE:'||TRUNC(
DATE: 04-JUL-07
UT1 > select 'DATE: '|| (sysdate - 1) from dual;
'DATE:'||(SYSDA
DATE: 04-JUL-07
You just need to get Oracle to do the math before it does the datatype conversion.
