①DB2取得所有非系統表：

SELECT RTRIM(TABSCHEMA) AS CONTNAME,
       RTRIM(TABNAME) AS NAME,
       RTRIM(TBSPACE) AS TBSPACE,
       DEFINER AS DEFINER
FROM SYSCAT.TABLES
WHERE (LEFT (TABSCHEMA,3) <> 'SYS')
AND   (TYPE = 'T')
ORDER BY CONTNAME, NAME FOR FETCH ONLY;       

②DB2取得表結構相關資訊

SELECT RTRIM(C.TABSCHEMA) AS CONTCONTNAME,
       C.TABNAME AS CONTNAME,
       C.COLNAME AS NAME,
       C.REMARKS AS COMMENT,
       TC.TYPE AS ISPRIM,
       SECLABELNAME AS SECLABELNAME,
       RTRIM(C.TYPESCHEMA) AS SOURCE_SCHEMA,
       C.TYPENAME AS SOURCE_NAME,
       C.LENGTH AS LENGTH,
       C.SCALE AS SCALE,
       C.CODEPAGE AS CODEPAGE,
       C.NULLS AS NULLS,
       C.COMPRESS AS COMPRESS,
       C.DEFAULT AS DEFAULT,
       C.GENERATED AS GENERATED,
       C.TEXT AS TEXT,
       C.IDENTITY AS IDENTITY,
       C.LOGGED AS LOGGED,
       C.COMPACT AS COMPACT,
       C.PARTKEYSEQ AS PARTKEYSEQ,
       RTRIM(C.DL_FEATURES) AS DL_FEATURES,
       C.INLINE_LENGTH AS INLINELENGTH,
       CID.START AS START,
       CID.INCREMENT AS INCREMENT,
       CID.CACHE AS CACHE,
       CID.MINVALUE AS MINVALUE,
       CID.MAXVALUE AS MAXVALUE,
       CID.CYCLE AS CYCLE,
       ORDER AS ORDER
FROM SYSCAT.COLUMNS C 
     LEFT OUTER JOIN SYSCAT.KEYCOLUSE KCU ON KCU.TABSCHEMA = C.TABSCHEMA 
        AND KCU.TABNAME = C.TABNAME 
        AND KCU.COLNAME = C.COLNAME 

     LEFT OUTER JOIN SYSCAT.TABCONST TC ON TC.CONSTNAME = KCU.CONSTNAME 

     LEFT OUTER JOIN SYSCAT.COLIDENTATTRIBUTES CID ON CID.COLNAME = C.COLNAME 
        AND CID.TABNAME = C.TABNAME AND CID.TABSCHEMA = C.TABSCHEMA

WHERE (LEFT (C.TABSCHEMA,3) <> 'SYS')
AND   (C.TABNAME = 'TABLE_NAME')
AND   (RTRIM (C.TABSCHEMA) = 'TABSCHEMA')
ORDER BY COLNO FOR FETCH ONLY;
 

③建立表

create table "jzy"."TEST" 
(
    ROLE_ID              varchar(8)                     not null,
    SYS_CODE             varchar(3)                     not null,
    ROLE_CODE            varchar(3)                     not null,
    ROLE_NAME            varchar(3)                     not null
)
