Thanks in advance.

you picked a great example; in your presentation, if you removed the decimal, how do you know that

78925 is not one of these values: 7892.5 ,789.25 or 78925? don't you really need to round them up or down to the integer value, instead of stripping decimal? or multiply by 100 to get consistent values?

anyway you could do it like this:

SELECT REPLACE(CONVERT(varchar, 7892.5),'.','')

If you simply want to get rid of the decimal point, you can use the REPLACE funtion to replace it with a zero-length string, i.e.

SELECT REPLACE(yourColumn, '.' ,'') AS yourColumn

I'm guessing it's a primitive $ -> ¢ conversion?

But as Lowell has already pointed out, you'd need to be 100% sure that the source varchar value always has a consistent number of decimals, i.e. 100 is represented as 100.00 and 100.1 is represented as 100.10. Otherwise you will get a misrepresented value by just removing the decimal point.

So it would be a better and more robust solution to do an intermediate conversion to a decimal type, multiply by 100, and convert back to varchar (if that is the type you ultimately aim for), i.e. something like this:

SELECT CONVERT(varchar(20),CONVERT(int,TRY_CONVERT(dec(15,2),yourColumn)*100)) AS yourColumn
