select to_char('10','10') from dual This gives me an error oRA-1481 INVALID ..

Answer / mohammad islam

The format is to_char('10','0,999.99')
or to_char(10,'0,999.99')
What is the meaning of it? It means 10 has to be 4 digit
long number with comma after the first digit and 2 digit
decimal places
like 0,010.00

But for to_char('10','0999.99'), the result would be
0010.00 because 4 digit before the decimal place with no
comma and 2 digit after the decimal place

And for TO_CHAR(1230,'00,999.99'), the result is
01,230.00(as you see 5 digit before decimal and 2 digit
after decimal and comma after 2 digit.

I hope it will clear everything

Thanks,
Mohammad Islam

Answer / kumar

We can use TO_CHAR function in two ways.
1. To convert a number into a character.
TO_CHAR(-) will take one parameter i.e, number
2. To convert a date into a character.
TO_CHAR(-,-) will take two parameters
i) first parameter is the date
ii) Second parameter is format in which we have to
convert, that to the second parameter should be enclosed
with single Quotes.

Answer / neha k

to_char function can take both Number and String Values but
one at a time.

ie. select to_char(10) from dual;
select to_char('10') from dual;

both are valid.

Another form of overloaded function to_char accepts two
arguments first is Date and second if its format in which
it needs to be converted as string.

ie. select to_char(sysdate,'YYYYMMDD') from dual;
