ORA-00936: missing expression   Cause: A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.   Action: Check the statement syntax and specify the missing component.

我遇到的2種  ORA-00936: missing expression 報錯情況1、插入表資料 insert into t1 values select 1 from dual;2、用pl/sql developer 工具比較時報錯  原因：表字段是oracle關鍵字----也就是在查詢這個帶有關鍵字列的時候測試1：SQL> create table t1 ("desc" varchar2(10));

表已建立。

SQL> desc t1;名稱                                      是否為空? 型別----------------------------------------- -------- ----------------------------desc                                               VARCHAR2(10)

SQL> insert into t1 values select 1 from dual;insert into t1 values select 1 from dual                      *第 1 行出現錯誤:ORA-00936: 缺失表示式SQL>解決就是把values去掉就可以了

測試2：SQL> select desc from t1;select desc from t1       *第 1 行出現錯誤:ORA-00936: 缺失表示式

SQL>測試2(2)：用pl/sql developer 工具比較時的報錯解決方法：ALTER TABLE T1 RENAME COLUMN "desc" TO desc_;(比較的話目標和源庫都要相同)再比較或者查詢就沒有問題了祝好~
