In one table i have one column named "today_date" as type varchar; And another table i have another column named"cf_Auth_dt" as type date. So i need to substract these dates . Can any body give idea !!! Thanks and Regards Reddy
I tried to do a simple subtract on a table with two dates (in Oracle) and it seems to return a real value representing the number of days/hours [eg., 12.75 = 12.75 days, or 12 days and 18 hours]. So you just have to convert the varchar date into a date field. Something like this:
You need to specify the correct format for the varchar date [however it's stored in the database], and the rest should be fairly obvious. This is how it's done in SQL.
