如何将 Oracle SQL 转换为 DB2？

Question

masters~ I'm having trouble converting Oracle SQL to DB2.

I need to change these Oracle SQLs to DB2.

Please help me

CREATE TABLE ABC (
   AA VARCHAR(10 BYTE) WITH DEFAULT TO_CHAR(SYSDATE, 'YYYYMMDDHH24MISS')
);


CREATE TABLE CBA (
BB  INTEGER(22) NOT NULL
) PCTFREE 10 TABLESPACE CC STORAGE (INITIAL 32K NEXT 32K) NOLOGGING;

Answer 1

What with all the concerns @Bob Jarvis mentioned in the comment to the original post, here is some rough equivalents that might get you by. You should probably consult the Information Center documentation a bit for further reference.

CREATE TABLE ABC (
   AA TIMESTAMP WITH DEFAULT CURRENT TIMESTAMP GENERATED BY DEFAULT
);


CREATE TABLE CBA (
    BB  BIGINT NOT NULL
);

If you're generating timestamps, you should store them as such, not as character strings.

Also, there is a NOT LOGGED option on DB2 tables, but it is only valid for LOB data types. (Or, there is NOT LOGGED INITIALLY , which will not log any changes that are applied in the same unit of work as the table creation, which is useful, for example, when importing data from another source [file or other table, perhaps])
