How to always show two decimal places on a number in PL/SQL

Question

Folks,

I have a existing stored procedure that I\'m trying to update to always show two decimal places even when it\'s a whole number or single decimal number.

Answer 1

You actually, have to insert the data with formatting. (Assuming the targeted column is VARCHAR) What ever format you fetch and put into a NUMBER variable, will be a NUMBER.

A number doesn't have a format to be saved after-all. Only for display, the formatting comes into picture.

insert into SQL_TXT values (TO_CHAR(v_credit_amt,'FM99999.00'));
commit;

If the INSERT-ed column is NUMBER again.

You still want to go with

SELECT TO_CHAR(COL1,'FM99999.00') FROM SQL_TEXT;
