SSIS中DB2压缩十进制与SQL Server DT_NUMERIC之间的查找转换

Question

We use DB2 as our main production database, but we use SQL Server for many other things ie to do integration between other customers and vendors via EDI etc.
I have a table in SQL with SO numbers and I try to make a lookup in DB2 to get all the invoices for the SO's in my table, so here's what I did.

1. Created a connection to the DB2 using the Microsoft® OLEDB Provider for DB2
2. Created a data fllow with a source using a SQL Server connection.
3. Added a Data Conversion Transformation trying to convert the INT so value to a decimal with a precision of 12, but I couldn't change a precision in a DT_DECIMAL, so the only datatype that I have the option to change the precision is DT_NUMERIC.
4. Added a lookup transformation to lookup the data withing DB2.

Now when i try to create the join between the source table and DB2 I get an error Cannot map the input column, 'so', to the lookup column, 'orno', because the data types do not match.
According to Microsoft this is not a bug and they suggest to use the DT_NUMERIC where you can change the precision.
If I try to convert the SO to a DT_DECIMAL without changing the precision I'd get the same error mentioned above.

Is there any way to work around the limitations from SSIS and change the precision in a DT_DECIMAL conversion so I could do the match?

Or any other suggestions?

Answer 1

The simple answer is to change the connection property in the DB2 connection to treat DECIMAL as NUMERIC.
