Answer 1

试试这个

bList

Answer 2

你可以试试......

select * from A, B where B.id like concat('%', A.id ,'%');

Answer 3

DDL＆安培; DML

          CREATE TABLE A_TABLE
          (ID VARCHAR2(50),GROUPP VARCHAR2(50))

          INSERT INTO A_TABLE(ID,GROUPP)VALUES('6ZE','A');
          INSERT INTO A_TABLE(ID,GROUPP)VALUES('UZC','A');
          INSERT INTO A_TABLE(ID,GROUPP)VALUES('LQY','B');
          INSERT INTO A_TABLE(ID,GROUPP)VALUES('HO7','B');
          INSERT INTO A_TABLE(ID,GROUPP)VALUES('V4P','C');
          INSERT INTO A_TABLE(ID,GROUPP)VALUES('KR0','C');
          COMMIT;

          CREATE TABLE B_TABLE
          (ID VARCHAR2(50),DATA VARCHAR2(50));


          INSERT INTO B_TABLE(ID,DATA)VALUES('6ZE, FET, UZX','50048');
          INSERT INTO B_TABLE(ID,DATA)VALUES('UZC, LQY','89871');
          INSERT INTO B_TABLE(ID,DATA)VALUES('LQY, E03','31579');
          INSERT INTO B_TABLE(ID,DATA)VALUES('HO7, 7KT, LXW, EK8','17260');
          INSERT INTO B_TABLE(ID,DATA)VALUES('V4P, MKP, TPJ','37344');
          INSERT INTO B_TABLE(ID,DATA)VALUES('KR0','50044');
          COMMIT;

并选择脚本

  SELECT A.ID,A.GROUPP,B.ID,B.DATA
              FROM
              A_TABLE A
              JOIN
              B_TABLE B
              ON B.ID LIKE '%'||A.ID||'%'

拆分不是常用功能

Answer 4

SELECT *
FROM A_TABLE INNER JOIN B_TABLE ON FIND_IN_SET(A_TABLE.id, B_TABLE.id)
