Error converting data type varchar to numeric

[lornab]

Hi

I wonder if anyone can help - I think the answer is simple but it's been a really long day and I need to get this done!!

My select statement goes like this...


SELECT
client,
apar_id,
ext_inv_ref,
case when amount ='' then '0' else amount end,
currency,
convert (varchar,paymen t_date,112),
voucher_no,
convert (varchar,vouche r_date,121)

from acuhistr
where client = 'SD'
and account = '9299'

I get the error: Server: Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

I get why it's saying it, but I cannot work out how to convert the 'blank' into numeric or the numeric into varchar! Any ideas muchly appreciated

What's the data type of your amount column? What do you mean by this line:

case when amount ='' then '0' else amount end

Error converting data type varchar to numeric

Hiya

The amount column is a numeric I believe. What I am saying in the case statement is if the amount is blank then populate the result with 0 or 0.00 or else put the result amount in.

I have just rerun the query, and I have actually got .000 in my result! I think my problem actually lies in getting it to print the 0.00 or.000 in my ARW that I am putting the sql into. This is my result so far:
SD 29963 888 299.000 DKK 20091001 3000000 2009-10-01 00:00:00.000
SD 29963 444 .000 DKK 20091001 3000002 2009-10-01 00:00:00.000

Thanks anyway, but I am going to have to look at my report that I am using the sql in rather than the sql itself....I think it's going to be another long day :)

By default, numeric data stores NULL, not blank. If what you're trying to do is to return 0 or 0.00 instead of NULL, use the ISNULL() function instead.

Happy Coding!!!
