Sql 我正在尝试使用select和value插入

我正在尝试使用SELECT和values将插入，但没有效果

表来源：

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)

要修改的表：

  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
  );

表来源：

id_task | id_node | id_word 
  10    |    20   | 30

要修改的表：

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

试试这个：

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;

试试这个：

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;

---

因此，您尝试的SQL是：

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> 

这会失败，因为查询投影中的数据类型与表中列的顺序不匹配。因此，请更改SELECT语句或在INSERT子句中定义顺序：

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.

您尝试过的sql代码是什么？插入到TS$SEQUENCES\u NEW中，从TS$SEQUENCES中选择TS$SEQUENCES.ID\u TASK作为“VALUE”，选择“ID\u TASK”作为“ID\u code”，选择“VACIO”作为“code\u SUBSEQUENCE”；您尝试过的sql代码是什么？插入到TS$SEQUENCES\u NEW中，从TS$SEQUENCES中选择TS$SEQUENCES.ID\u TASK作为“VALUE”，选择“ID\u TASK”作为“ID\u code”，选择“VACIO”作为“code\u SUBSEQUENCE”；我真的花了八分钟来编写示例代码吗？当你玩得开心的时候，时间不会飞逝吧！谢谢，我忘记了要替换的参数。我真的花了八分钟来编写示例代码吗？当你玩得开心的时候，时间不会飞逝吧！谢谢，我忘记了要替换的参数。
