Hi everyone,
I'm trying to create a derived table that has a dimension that calculates either next row's value or the previous row's value (next or previous doesn't matter).

Hello,
I am trying to use SSRS to pass parameters into a derived table in Teradata. The parameters represent a SQL Server table that is about 1600 rows. 
The join I'm trying is
 JOIN (Select ? (varchar(4)), ? (varchar(4))) as derivedtable (Col1Name, Col2Name) on (Col2Name=TDcol)
 

Hi Gurus,

I am looking for some guidelines on when to use each of the following form of temporary tables:

1) Derived Table

2) Volatile Table

3) Global Temporary Table

Any pointers will really help.

 

We stumbled upon this by accident. We have a query that runs much faster when a group by is added to a derived table when one of the columns in the derived table is the result of a cast/concatenation operation.

The first query/explain posted below has the group by in the derived table. It shows the cast/concatenation being resolved when the derived table is materialized in step 2 in the EXPLAIN. Result is 761 rows and I assume 761 resolutions of the cast/concatenation. The group by does not eliminate any dups.
