Van Halbert created TEIID-2497:
----------------------------------
Summary: Add support for DECODE(column, column_value,
column_to_replace_with)
Key: TEIID-2497
URL:
https://issues.jboss.org/browse/TEIID-2497
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 7.7.6
Reporter: Van Halbert
Assignee: Steven Hawkins
Looking at pivot and trying to use it like:
Select salesperson, SUM(DECODE(product, 'CarA', amount)) as ProductCarA,
SUM(DECODE(product, 'CarB', amount)) as ProductCarB,
SUM(DECODE(product, 'CarC', amount)) as ProductCarC
From SALES
Group By salesperson
Teiid's Decode requires you to know the value to substitute, with this option, it can
be dynamically substituted at run time.
