Problem IC69031 | Status: Closed |
STATISTICAL AND REGRESSION AGGREGATE FUNCTIONS SHOULD RETURN DECFLOAT IN NUMBER COMPATIBILITY MODE | |
product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problem description: | |
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 | |
