RE: sql query substr

And, I'm fairly certain it was in 8.0, and I wouldn't be surprised if it were in 7.3 and earlier as well...;-)

Too late, there it is, in the 'Format models' section of the 8i docs.



<sigh>

	Thanks Jim,  I learned something today.  :)
	
	Do you know what at which version the 'fill mode' was
introduced? 
	
	Please don't say 8i, or 7.3.  
	
	I'd hate to think I had missed it for that long.  :)

		Krishnan, this is how the to_char function works:  it
always leaves one extra leading space in the output to accommodate a
potential minus sign when the format mask consists only of "9 "s (and
potentially a decimal point alignment character).  You can eliminate
this by including the "fm " (fill-mode) element ( i.e., "fm99.99 "), or
use the "tm " (i.e., "text minimum " ) element.  In the "tm " case, you
can only follow this element with a single "9 ", i.e., "tm9 ", in your
format mask.

				Hello List,

				Look into the queries below,  why the
result of first two queries is starting with a blank space, and to get
rid of this I have to substr from position 2 rather than 1. 

				select
substr(to_char(34.25,'99.99'),1,5) col1 from dual;   --result is ' 34.2'
				select
substr(to_char(-4.25,'99.99'),1,5) col1  from dual;  --result is ' -4.2'
				select
substr(to_char(34.25,'99.99'),2,5) col1  from dual;  --result is '34.25'
				select
substr(to_char(-4.25,'99.99'),2,5) col1  from dual;  --result is '-4.25'

				TIA

				Krishan
