Convert varchar to decimal

Hello, I am running a SELECT statement on a varchar 50 field. I would like
to convert the output to a numeric field with 2 decimal places. I tried a
CAST but that didn't work. Any suggestions would be appreciated. Thanks,

Not knowing the largest decimal value you might wish to display, you could
do something like this:
SELECT CONVERT(<varchar field>, dec(10,2)) AS FieldName
FROM TableName
This will allow a total of 10 digits with 2 on the right of the decimal
point.

What didn't work?
Did you receive an error message?
If so, what?
If not, show us your code.

I tried CONVERT(FieldValue7, (dec(10,2)) AS NewFieldName
and got:
'dec' is not a recognized function name
Got the same error using 'decimal'. I am running a successful
SELECT CONVERT (CHAR (8), Field8, 112) AS Field8Text but the dec didn't work
.

I got the msg "Unable to convert varchar field" when using CAST. I am
taking data from a varchar and trying to format it to a numeric field, 10
wide with 2 decimal spaces. Pls see code above in my reply to Rick. Thanks

Pancho.

What does "didn't work" mean? What did you try? Are you sure all of the
values are really numeric and can be converted? If so, why are you storing
them in a VARCHAR(50) column?|||> I tried CONVERT(FieldValue7, (dec(10,2)) AS NewFieldName

Did you try using the right syntax?
NewFieldName = CONVERT(DECIMAL(10,2), FieldValue7)|||> I got the msg "Unable to convert varchar field" when using CAST.
Well, because you decided to use a VARCHAR(50) to store decimals, invariably
you will get varchar data that is not a decimal.
You shouldn't be really surprised by this.
A start would be to filter out the rows where ISNUMERIC(column_name) = 0.
However, ISNUMERIC() is not perfect either, see http://www.aspfaq.com/2390
Then, try cleaning up your data and fixing the data type. When you do that,
you won't need to do a convert at all.|||You got me. I didn't design this DB; a vendor did. I would not have stored
a field which has cash values as a varchar either. I'm trying to convert it
from one vendor to another.
Thanks everyone for your comments. I'm closing this one now.

Ooops.. Got it backwards. Thanks Aaron.

convert value to 2 decimal places?

Hello, is there a way to convert the value to just 2 decimal places, I created the report in Reporting Services and it has quite a few digits to each value. I looked at the table and found that the data type is {Float}. Is there a way to convert the values to just 2 decimal places?..Thank You.

Try this...

Code Snippet

select cast(columnName as numeric(10,2)) as 'columnName' from tableName

|||That worked, Thank You...
