過程中的動態更新查詢

Question

我正在嘗試爲DB中所有表中列出的列創建動態更新查詢。但是，查詢失敗，錯誤代碼：-942消息：ORA-00942：表或視圖不存在ORA-06512：在 「MANTAS.P_JRSDCN_TR」，線路14

代碼： -

CREATE or REPLACE PROCEDURE P_JRSDCN_TR 
(
out_error_cd out number,  -- Returns 0 if no error; anything else is an error 
out_error_msg out varchar2  -- Returns empty string if no error; otherwise the error and trace 
)AUTHID CURRENT_USER 
IS 
    counter number(20) :=0; 
CURSOR TAB_COL_CURSOR IS 
SELECT DISTINCT OWNER||'.'||TABLE_NAME as TABLE_NAME,COLUMN_NAME FROM ALL_TAB_COLS WHERE TABLE_NAME IN ('KDD_REVIEW') AND COLUMN_NAME='JRSDCN_CD'; 
BEGIN 
    FOR TAB_COL_REC IN TAB_COL_CURSOR 
    LOOP 

EXECUTE IMMEDIATE 'UPDATE TAB_COL_REC.TABLE_NAME SET TAB_COL_REC.COLUMN_NAME = P2||SUBSTR(TAB_COL_REC.COLUMN_NAME,3) WHERE SUBSTR(TAB_COL_REC.COLUMN_NAME,1,2)= PL'; 

counter := counter +SQL%rowcount ; 
If counter >= 50000 then 
    counter := 0; 
    --commit; 
    end if; 

-- Done!  
    out_error_cd := 0; 
    out_error_msg := ''; 
    dbms_output.put_line('Turkey Jurisdiction Update completed sucessfully at ' || to_char(sysdate,'MM/dd/yyyy HH24:MI:SS')); 
     END Loop; 
exception when others then 
     rollback; 
     out_error_cd := SQLCODE; 
     out_error_msg := substr(sqlerrm, 1, 200) || chr(10) || substr(DBMS_UTILITY.FORMAT_ERROR_BACKTRACE, 1, 3896);   
     dbms_output.put_line(' Code: ' || out_error_cd); 
     dbms_output.put_line(' Message: ' || out_error_msg); 
     dbms_output.put_line('Turkey Jurisdiction Update FAILED at ' || to_char(sysdate,'MM/dd/yyyy HH24:MI:SS')); 
end; 
/

感謝您對此程序的幫助。

可能沒有ta BLE稱爲TAB_COL_REC.TABLE_NAME

你可能想是這樣的：

EXECUTE IMMEDIATE 'UPDATE ' || TAB_COL_REC.TABLE_NAME || ' SET ' || TAB_COL_REC.COLUMN_NAME || ' = P2||SUBSTR(' || TAB_COL_REC.COLUMN_NAME ||',3) WHERE SUBSTR(' || TAB_COL_REC.COLUMN_NAME || ',1,2)= PL';

選擇a.table_name，列名，DATA_TYPE，DATA_LENGTH從ALL_TAB_COLUMNS
一個，USER_ALL_TABLESü 其中一個。 TABLE_NAME = u.TABLE_NAME 和column_name like'empid％' order by DATA_LENGTH desc;
