I used following coding in form to find the months between

BEGIN
	:FINANCED_DETAILS.due_date	:=	TO_CHAR(:FINANCED_DETAILS.emi_end_dt, 'ddth') || ' OF MONTH';
	:FINANCED_DETAILS.fin_tenure	:=	MONTHS_BETWEEN (:FINANCED_DETAILS.emi_end_dt, :FINANCED_DETAILS.emi_start_dt) || ' MONTHS';
END;

If i am giving input
emi_end_dt = '07-jan-2017' and
emi_start_dt = '07-jan-2014' its working fine and giving output 36 months

But If i giving input
emi_end_dt = '31-mar-2014' and
emi_start_dt = '01-feb-2016' its not giving output but giving me error ORA-06502

Can anyone tell me how to solved this

Are those fields DATEs or VARCHAR2s?

emi_start_dt & emi_end_dt are DATE columns And others are VARCHAR2(30)

What is data type of fin_tenure?
MONTHS_BETWEEN returns the NUMBER of months. So, if you assign number to a character type you would get ORA-06502.

This is, I suspect, because :FINANCED_DETAILS.FIN_TENURE length is too short to accept the whole value of MONTHS_BETWEEN concatenated with 'MONTHS'.

It was OK for a whole number ("36 months"), but failed for a (negative) decimal number ("-22.032258 months").

In addition to what I said above, fin_tenure field might be too short to hold the entire characters being assigned. Just test a bit more and check.

[LF was too quick to post around the same time I posted Smile

... if you assign number to a character type you would get ORA-06502.

You would? Poor you, most of us (who use Oracle) wouldn't.

I meant the other way round, but just typed the opposite. Must go to sleep now Smile

As LF already said the negative value might be an issue, I suspect the problem might be the input values. The end date being less than the start sate. @OP, is it a typo?

thank you guys for your reply...

the datatype of field tenure is VARCHAR2(30) and what if the input is
emi_end_dt = '01-feb-2016' and
emi_start_dt = '31-mar-2014' but its still giving error.

so I add ROUND function after function MONTHS_BETWEEN and now its giving output

BEGIN
	:FINANCED_DETAILS.due_date	:=	TO_CHAR(:FINANCED_DETAILS.emi_end_dt, 'ddth') || ' OF MONTH';
	:FINANCED_DETAILS.fin_tenure	:=	ROUND(MONTHS_BETWEEN (:FINANCED_DETAILS.emi_end_dt, :FINANCED_DETAILS.emi_start_dt)) || ' MONTHS';
END;

Or should I use following code as you guys said number => character storing giving error

BEGIN
	:FINANCED_DETAILS.due_date	:=	TO_CHAR(:FINANCED_DETAILS.emi_end_dt, 'ddth') || ' OF MONTH';
	:FINANCED_DETAILS.fin_tenure	:=	TO_CHAR(ROUND(MONTHS_BETWEEN (:FINANCED_DETAILS.emi_end_dt, :FINANCED_DETAILS.emi_start_dt))) || ' MONTHS';
END;

But I want to know which code should i used or do I have to do something different here...

If you're not going to specify a format mask for the to_char there's no real difference between them.
Oracle implicitly to_chars the number when concatenating it to a string.

Hey thanks, so i guess have to use to_char ('data', '999'). And what about the 1st method which doesn't contain to_char, is there a problem for not using it...

No problem; Cookiemonster told you, Oracle will implicitly convert number to character. However, TO_CHAR would indicate that you care about what you are doing and have control over it.
