CREATE TABLE "mmm"."test" ( --建表語句
"A" DATE,
"B" VARCHAR(36),
"C" VARCHAR(50),
"D" VARCHAR(25) not null,
"E" VARCHAR(15) not null,
"A" DATE,
"B" VARCHAR(36),
"C" VARCHAR(50),
"D" VARCHAR(25) not null,
"E" VARCHAR(15) not null,
) IN "MA_DATA"
DISTRIBUTE BY hash ("C") ;
alter table "mmm"."test" add primary key(D,E); --建立聯合主鍵語句 就是執行這個語句時報此錯誤；
錯誤原因是必須要把 DISTRIBUTE BY hash ("C") ; 改為聯合主鍵的任意一個欄位就ok了
如下
drop table "mmm"."test" ;
CREATE TABLE "mmm"."test" ( --建表語句
"A" DATE,
"B" VARCHAR(36),
"C" VARCHAR(50),
"D" VARCHAR(25) not null,
"E" VARCHAR(15) not null,
) IN "MA_DATA"
DISTRIBUTE BY hash ("D") ;
