SAP MaxDB 7.9 – Upgrade to 7.9.08.23 recommended
Because of a potential MaxDB issue in MaxDB versions 7.9.08.18 – 7.9.08.22 an upgrade to 7.9.08.23 is recommended.
Other versions are not affected.
You create an index (CREATE INDEX) for a subsequently added table column that has been given a
default value (SQL statement ALTER TABLE ADD). This index may contain incorrect values.
If you are using version 7.9.08.18 – 7.9.08.22 SAP strongly recommends to do a MaxDB upgrade to version 7.9.08.23.
