Manipulating Data

[narpet]

Hello all...

I have a table that inlcudes a field that represents a percentage value (like 1.23), but the data is presented as 000123 (hope that makes sense). I get the data from a location outside of my office and I have no say in how the data is formatted.

I need to run a query that multiplies one field by this above mentioned field.

Is there a way to convert the value to the way I need it programmaticall y (in a query) without putting it in a temporary table?

Example:

Table 1 - fields - ID, Amount
Table 2 - fields - Type, Percentage

Table 1 (one row of data) - 1 234
Table 2 (one row of data) - A 000123

I want to multiply the Amount from Table 1 (234) by the Percentage from Table 2 (000123) where the Type from Table 2 is equal to A.

This should be worked out as 234 * 1.23

Thanks for any help.

first, how are the two tables related? although these two tables may still be joined even if they are not related, it's a rare situation that you will join two unrelated tables.

try this:
select 1, amount, type, percentage, amount * cast(percentage as float)/100.00
from table1
full outer join table2 on cast(id as varchar(2)) = cast(type as varchar(2)).
and type = 'A'

since "full outer join" joins the two table wheather there matched records or not, it will always return the values on the right

i did not test this query, is this right?

I'm not at work right now. I will test this when I get in on Monday morning. Thanks for the info... I will post and let you know how this works. As an answer to your question... the two tables will be joined by a common account number.

then you use account number as the join key. whether it'll be an outer, left, right or inner join will be up to your requirement

That worked perfectly. Thanks very much for the help!
