MSSQL 2008 Precision Problem

Question

Hello everyone,
I have a problem about precision range in MSSQL 2008. I am trying to transfer data from Oracle db to MSSQL db. One column in Oracle db has a precision larger than 38, which is '76.43448990049567164100213185805651059565'. Therefore, I give an execution error
like;
Caused By: weblogic.jdbc.sqlserverbase.ddc: [FMWGEN][SQLServer JDBC Driver]The number, 76.43448990049567164100213185805651059565, has a precision larger than allowed by the SQL Server.
What can I do at this point? Please help me
Thank You

Dilek,
Do you really need that many decimal places? try limiting it down if possible. BEcause, SQL Server allows a max of precision value of 38 only in case of decimal/numeric. So you have the following alternatives:
Reduce the number of decimal places and push it into SQL Server column having a datatype say, numeric(38,36)
Split the value into two columns one for the absolute part having int type and another for decimal which can either have numeric(38,38) or an int which is to be converted to decimal during usage.
Store as varchar type - but this would make it difficult to be used for calculation (Beware, even when you convert a 40 digit precision value from varchar to numeric you'll get the same error). So if it just for projecting the data (just for select) varchar
should do fine.
--method 1
declare @tab table ( num numeric(38,36))
insert @tab select 76.434489900495671641002131858056510595--65
select * from @tab
--method 2
declare @tab table ( num int,dec numeric(38,38))
insert @tab select 76,0.43448990049567164100213185805651059565
select * from @tab
select cast(num as varchar)+substring(cast(dec as varchar(100)),2,len(cast(dec as varchar(100)))),* from @tab
select num+dec,* from @tab --decimal places get reduced beware..
--method 3
declare @tab table ( num varchar(100))
insert @tab select 76.434489900495671641002131858056510595--65 -- ignoring last two digits
insert @tab select '76.43448990049567164100213185805651059565' -- as varchar
select cast(num as decimal(38,36)) from @tab --produces result for first one and error for second instance
--Just normal
select 76.434489900495671641002131858056510595 --works
select 76.43448990049567164100213185805651059565 -- doesnt work
Thanks,
Jay
