即時嘗試使插入與選擇和價值

Question

我想做一個INSERT INTO與SELECT和值，但沒有作品。

TABLE SOURCE：

CREATE TABLE "MICV_PRE"."TS$SEQUENCES" 
    (
    "ID_NODE"  NUMBER DEFAULT 1 NOT NULL ENABLE, 
    "ID_TASK"  NUMBER DEFAULT 1 NOT NULL ENABLE, 
    "ID_DOCUMENT" NUMBER DEFAULT 1 NOT NULL ENABLE, 
    "ID_WORD"  NUMBER DEFAULT 1 NOT NULL ENABLE, 
    "ID_TEAM"  NUMBER DEFAULT '1' NOT NULL ENABLE) 

修改表中：

CREATE TABLE TS$SEQUENCES_NEW(
    "ID_CODE" VARCHAR(255 CHAR) NOT NULL ENABLE, 
    "CODE_SUBSEQUENCE" VARCHAR2(255 CHAR) NOT NULL ENABLE, 
    "VALUE" NUMBER(10,0) NOT NULL ENABLE 
); 

表源：

id_task | id_node | id_word 
    10 | 20 | 30 

表來修改：

id_code | code_subsequence | value 
"id_task" | "empty"   | 10 
"id_node" | "empty"   | 20 
"id_word" | "empty"   | 30 

Answer 1

所以，你試過SQL是這樣的：

SQL> INSERT INTO TS$SEQUENCES_NEW 
    2 SELECT TS$SEQUENCES.ID_TASK AS "VALUE", 'ID_TASK' AS "ID_CODE", 'VACIO' AS "CODE_SUBSEQUENCE" 
    3 FROM TS$SEQUENCES 
    4/
                   * 
ERROR at line 2: 
ORA-01722: invalid number 


SQL> 

失敗的原因是在查詢的投影數據類型不匹配的列的順序表。因此，要麼改變SELECT語句，要麼在INSERT子句中定義順序：

SQL> INSERT INTO TS$SEQUENCES_NEW ("VALUE", "ID_CODE","CODE_SUBSEQUENCE") 
    2 SELECT TS$SEQUENCES.ID_TASK AS "VALUE", 'ID_TASK' AS "ID_CODE", 'VACIO' AS "CODE_SUBSEQUENCE" 
    3 FROM TS$SEQUENCES 
    4/

1 row created.

Answer 2

試試這個：

INSERT INTO TS$SEQUENCES_NEW (VALUE, ID_CODE, CODE_SUBSEQUENCE) 
SELECT TS$SEQUENCES.ID_TASK AS "VALUE", 'ID_TASK' AS "ID_CODE", 'VACIO' AS "CODE_SUBSEQUENCE" 
FROM TS$SEQUENCES;
