Question
Update statement in DB2 SQL. - Column Qualifier or table undefined.
Hello experts.
I am reasonably familiar with SQL Server, but a complete novice with DB2. I have a SQL statement that I have defined in TSQL. I tested it on SQL Server and it works fine. I was hoping to run the same statement on DB2. No such luck. The error I get is "Column Qualifier or table undefined"
The statement takes a set of records on a table, and copies them across other areas of the same table..
I have changed a couple of the field names to make them more readable, but the syntax is the same.
TSQL as below..
update t1
set accountcode = t2.accountcode
from accounttable t1 inner join accounttable t2
on t1.accountnum = t2.accountnum
and t1.subcode = t2.subcode
and t2.costcenter = 'MODEL'
where t1.costcenter <> 'MODEL'
The idea is that the accountcodes that are held for the model cost centre, a copied across the table, so that they apply to all other cost centres.
Each combination of costcenter, accountnum and subcode is unique in the accounttable.
How can I modify this statement so it works in DB2?
The DB2 interpreter doesn't seem to like the first reference to t2 on the second line.
