select convert(float,'1.2334e+006')
1233400.0

select convert(decimal(20,2),'1.2334e+006')
Server: Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

can I set some options arithabort etc to have a workaround to this
problem?
Thanks.

Try

select convert(decimal(20,2),1.2334e+006)

Hi Madhivanan,
Thanks for the input. The column type is varchar where the value
1.2334e+006 is stored. So I need to convert it to float as suggested by
some before converting it to decimal. Anyway, that brings another
issue. When running the query the server just errors out without giving
the value that causes the error. It just says 'conversion error'. I
had to take the SQl out and put it in a cursor and use a loop to find
out which row is actually causing the error and find the value
1.2334e+006. Is there any easier way to find out which row in the table
causes the SQL server to error out. For example can I set the error
level so that I find more information so that I can locate the row in
the table.
Thanks.

Unfortunately, there are not really any good options. The best is probably
to run a SELECT query, and takes some hint from where it terminates. This
example illustrates:
CREATE TABLE #tmp1 (a varchar(23) NOT NULL, b int IDENTITY)
go
INSERT #tmp1(a) VALUES ('1234')
INSERT #tmp1(a) VALUES ('1232')
INSERT #tmp1(a) VALUES ('2344')
INSERT #tmp1(a) VALUES ('34.34')
INSERT #tmp1(a) VALUES ('-1234')
INSERT #tmp1(a) VALUES ('-1234')
INSERT #tmp1(a) VALUES ('1234e+006')
INSERT #tmp1(a) VALUES ('777')
go
SELECT convert(decimal(20, 2), a) FROM #tmp1 ORDER BY b
go
DROP TABLE #tmp1
