hi friends,can any 1 help 2 solve the below issue?

From the numeric value,
the logic need to be applied
is:
round of 2 from the decimal and
finally only 2 values need to come

Eg:
Text1 is of type varchar

select text1 from test1
Text1
**********
10.000000000
10.020000000
abcd

output should come as:
Text1
10.00
10.02
abcd

update t
set text1 = convert(varchar(20), convert(decimal(20,2), text1))
from yourtable t
where isnumeric(text1) = 1
[/code]

Isnumeric() is not reliable

use

col not like '%[^.0-9]%'
