Problem IC69031
|
Status: Geschlossen |
STATISTICAL AND REGRESSION AGGREGATE FUNCTIONS SHOULD RETURN DECFLOAT IN NUMBER COMPATIBILITY MODE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
In NUMBER compatibility mode, the following statistical and
regression functions incorrectly return INTEGER, BIGINT or
DOUBLE where they should return DECFLOAT. 'integer' below means
SMALLINT, INTEGER or BIGINT:
AVG( SMALLINT or INTEGER ) returns INTEGER
AVG( BIGINT ) returns BIGINT
CORRELATION ( either argument is integer ) returns DOUBLE
COVARIANCE( either argument is integer ) returns DOUBLE
STDDEV( integer ) returns DOUBLE
VARIANCE( integer ) returns DOUBLE
REGR_SLOPE( either argument is integer ) returns DOUBLE
REGR_ICPT( either argument is integer ) returns DOUBLE
REGR_INTERCEPT( either argument is integer ) returns DOUBLE
REGR_R2( either argument is integer ) returns DOUBLE
REGR_AVGX( ..., integer ) returns DOUBLE
REGR_AVGY( integer, ... ) returns DOUBLE
REGR_SXX( ..., integer ) returns DOUBLE
REGR_SYY( integer, ... ) returns DOUBLE
REGR_SXY( either argument is integer ) returns DOUBLE |
