DB2无法创建MQT表

Question

我正在尝试在DB2 v10.5中创建DB2 MQT表，但是我收到以下错误消息：

意外的令牌“CREATE TABLE T_MQT AS（  在“BEGIN-OF-STATEMENT”之后找到SELECT ID，COL1，C“。预期的令牌可能包括：”“.. SQLCODE = -104，SQLSTATE = 42601，DRIVER = 4.16.53 SQL代码：-104，SQL状态： 42601

这是我的create table语句：

CREATE TABLE T (
   ID                VARCHAR(128)  NOT NULL,
   COL1              VARCHAR(128),
   COL2              VARCHAR(128),
   COL3              VARCHAR(128),
   COL4              VARCHAR(128),
   COL5              VARCHAR(128),
   PRIMARY KEY (ID)
);
CREATE TABLE T_MQT AS (
    SELECT ID, COL1, COL2, COL3 FROM T
)
DATA INITIALLY DEFERRED 
REFRESH IMMEDIATE 
SET INTEGRITY FOR T_MQT IMMEDIATE CHECKED NOT INCREMENTAL;

Answer 1

您在CREATE TABLE T_MQT ...语句和SET INTEGRITY语句之间缺少分号。

Answer 2

我发现原因是基表是“ORGANIZE BY COLUMN”。所以我将sql改为

    CREATE TABLE T (
       ID                INTEGER  NOT NULL,
       COL1              VARCHAR(128),
       COL2              VARCHAR(128),
       COL3              VARCHAR(128),
       COL4              VARCHAR(128),
       COL5              VARCHAR(128),
       PRIMARY KEY (ID)
    ) ORGANIZE BY ROW;
    CREATE TABLE T_MQT ( ID, COL1, COL2, COL3 )
    AS ( select ID, COL1, COL2, COL3  from T )
    DATA INITIALLY DEFERRED REFRESH IMMEDIATE MAINTAINED BY SYSTEM;
    SET INTEGRITY FOR T_MQT IMMEDIATE CHECKED FULL ACCESS;
