我正在尝试按如下方式编写查询：

例如：

 DECLARE 
 V_Output varchar(20):='';

 BEGIN
   INSERT INTO T(ID, MY_PK, NAME, VALUE)
   (SELECT ID, NEXT_TRAN_VALUE('T'), NAME, VALUE FROM T WHERE MY_PK = 'NO0000000000013');
   RETURNING MY_PK INTO V_Output;
   DBMS_OUTPUT.PUT(V_Output);
 END;

使用以下功能

create or replace FUNCTION NEXT_TRAN_VALUE (field IN VARCHAR2)   RETURN 
VARCHAR2
IS
n_value   VARCHAR2 (20);
P_APR     VARCHAR2(3);

CURSOR rec_exists IS SELECT * FROM TRANSACTION_SEQ where SEQ_NAME = field ;      
jk_seq_rec  TRANSACTION_SEQ%ROWTYPE;   
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
SELECT LC_CODE into P_APR FROM LOCATION_CONFIG;
OPEN rec_exists;
FETCH rec_exists INTO jk_seq_rec;

IF rec_exists%FOUND THEN
    UPDATE TRANSACTION_SEQ …
