觸發無效，未能重新驗證錯誤而插入記錄

Question

我的表像這樣用觸發器和序列：

CREATE TABLE "RTH"."TBL_USER" 
    ( "USR_ID" VARCHAR2(1 BYTE) NOT NULL ENABLE, 
    "USR_IS_ANONYMOUS" RAW(1), 
    "USR_FIRST_NAME" CLOB, 
    "USR_MID_NAME" CLOB, 
    "USR_LST_NAME" CLOB, 
    "USR_PRIMARY_EMAIL" CLOB, 
    "USR_ALT_EMAIL" CLOB, 
    "USR_PRIMARY_CNCT_NMBR" CLOB, 
    "USR_SECONDARY_CNCT_NMBR" CLOB, 
    "USR_TYPE" CLOB, 
    "USR_CATEGORY" CLOB, 
    "USR_DOB" TIMESTAMP (0), 
    "USR_CREATE_DT" TIMESTAMP (0), 
    "CUPN_ID" VARCHAR2(1 BYTE), 
    "USR_MARITIAL_STUTUS" VARCHAR2(20 BYTE), 
    "USR_GENDER" VARCHAR2(1 BYTE), 
    "USR_IMAGE" RAW(1), 
    "USR_PASSWORD" VARCHAR2(20 BYTE), 
    CONSTRAINT "XPKTBL_USER" PRIMARY KEY ("USR_ID") 
    USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 NOCOMPRESS LOGGING 
    TABLESPACE "USERS" ENABLE 
    ) SEGMENT CREATION DEFERRED 
    PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING 
    TABLESPACE "USERS" 
LOB ("USR_FIRST_NAME") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_MID_NAME") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_LST_NAME") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_PRIMARY_EMAIL") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_ALT_EMAIL") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING)

    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_SECONDARY_CNCT_NMBR") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_TYPE") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) 
LOB ("USR_CATEGORY") STORE AS BASICFILE (
    TABLESPACE "USERS" ENABLE STORAGE IN ROW CHUNK 8192 RETENTION 
    NOCACHE LOGGING) ; 


    CREATE OR REPLACE TRIGGER "RTH"."TBL_USER_TRIGGER" 
BEFORE INSERT ON TBL_USER 
FOR EACH ROW 
BEGIN 
SELECT TBL_USER_SEQ.nextval 
INTO :new.USR_ID 
FROM dual; 
END; 

ALTER TRIGGER "RTH"."TBL_USER_TRIGGER" ENABLE 
/
ALTER TRIGGER "RTH"."TBL_USER_TRIGGER" ENABLE; 

當我嘗試插入一條記錄，我得到一個錯誤說：

java.sql.SQLSyntaxErrorException: ORA-04098: trigger 'RTH.TBL_USER_TRIGGER' is invalid and failed re-validation 

插入記錄Java代碼：

String query = "insert into TBL_USER(USR_FIRST_NAME,USR_LST_NAME,USR_PRIMARY_EMAIL,USR_PASSWORD) values(?,?,?,?)"; 
PreparedStatement pst = con.prepareStatement(query); 

pst.setString(1, user.getFirstName()); 
pst.setString(2, user.getLastName()); 
pst.setString(3, user.getEmail()); 
pst.setString(4, user.getPassword()); 
pst.executeUpdate(); 

我試過網上找，但找不到我的錯誤，莫解決方案錯誤的ST都與甲骨文自己

更新：作爲建議的@Durga Viswanath，運行查詢：

select * from all_sequences where sequence_name = 'TBL_USER_SEQ'; 

得出以下結果：

SEQUENCE_OWNER     SEQUENCE_NAME     MIN_VALUE    MAX_VALUE    INCREMENT_BY   CYCLE_FLAG ORDER_FLAG CACHE_SIZE    LAST_NUMBER    
------------------------------ ------------------------------ ---------------------- ---------------------- ---------------------- ---------- ---------- ---------------------- ---------------------- 
RTH       TBL_USER_SEQ     1      9999999999999999999999999999 1      N   N   100     101      

1 rows selected 

現在，我得到插入記錄時出現新錯誤：

One error saving changes to table "RTH"."TBL_USER": 
Row 10: ORA-06502: PL/SQL: numeric or value error: character string buffer too small 
ORA-06512: at "RTH.TBL_USER_TRIGGER", line 2 
ORA-04088: error during execution of trigger 'RTH.TBL_USER_TRIGGER' 
ORA-06512: at line 1

像這樣運行以獲取觸發器的問題。按照異常觸發無效。

SQL> alter trigger tbl_user_trigger compile; 

Warning: Trigger altered with compilation errors. 

SQL> show errors 
Errors for TRIGGER TBL_USER_TRIGGER: 

<It will display errors here> 

此外，您可以運行此查詢以確認您是否有序列。語法上你的觸發代碼是正確的。

select * from all_sequences where sequence_name = 'TBL_USER_SEQ'; 

接聽ORA-06502: PL/SQL: numeric or value error: character string buffer too small

你有"USR_ID" VARCHAR2(1 BYTE) NOT NULL ENABLE,這意味着USR_ID只能存儲一個字符。一旦usr_id穿越9，它會拋出錯誤。您需要更改USR_ID的數據類型。
