Subj:   Re: Overflow on count(*) in queryman, bteq, wddi
 
From:   Chauhan, Amit

ANSI mode uses DECIMAL because Teradata tables frequently have a cardinality exceeding the range of INTEGER. Teradata mode uses INTEGER to avoid regression problems. When in Teradata mode, if the result of COUNT overflows and reports an error, you can change the script to use CAST, as illustrated by the following example.

SELECT CAST(COUNT(*) AS DECIMAL(15,0) FORMAT 'Z(14)9')
FROM BIGTABLE;
