Question

我们可以在存储过程中将分区作为参数传递吗？我收到了以下错误。请帮忙。

CREATE OR REPLACE PROCEDURE PROCEDURE_NAME (PARTITION_NAME IN VARCHAR2)  
     IS  
    LASTDATE VARCHAR2(12);  
ENDDATE VARCHAR2(12);  
BEGIN  
IF PARTITION_NAME='DEC_2014' OR PARTITION_NAME='JAN_2015' OR   PARTITION_NAME='MAR_2015' OR PARTITION_NAME='MAY_2015' OR   PARTITION_NAME='JUL_2015' OR PARTITION_NAME='AUG_2015' OR   PARTITION_NAME='OCT_2015' OR PARTITION_NAME='DEC_2015' OR   PARTITION_NAME='JAN_2016' THEN
ENDDATE:='31';
ELSIF PARTITION_NAME='NOV_2014' OR PARTITION_NAME='APR_2015' OR PARTITION_NAME='JUN_2015' OR PARTITION_NAME='SEP_2015' OR PARTITION_NAME='NOV_2015' THEN  
ENDDATE:='30';  
ELSE  
ENDDATE:='28';  
END IF;  
LASTDATE:=CONCAT(CONCAT(ENDDATE,'-'),REPLACE (PARTITION_NAME, '_', '-'));  
DBMS_OUTPUT.PUT_LINE(LASTDATE);  
DBMS_OUTPUT.PUT_LINE(PARTITION_NAME);  

UPDATE  
  /*+ PARALLEL(Alias 4) */  
  TABLE_NAME PARTITION (PARTITION_NAME) Alias  
SET Alias.Alias_D_EFFECTIVE_DATE =  
  (SELECT  
    /*+ PARALLEL(Alias3 4) */  
    ALAIS2.ALAIS2_D_DATETIME  
  FROM schema1.TABLE_2 ALAIS2  
  WHERE TRUNC(ALAIS2_D_DATETIME) <= TO_DATE(LASTDATE,'DD-MON-YYYY')  
  AND ALAIS2.ALAIS2_N_TRN_ID                     = Alias.Alias_N_PR  
  )  
WHERE EXISTS  
  (SELECT Alias3.ALAIS2_D_DATETIME  
  FROM schema1.TABLE_2 Alias3  
  WHERE TRUNC(Alias3.ALAIS2_D_DATETIME) <= TO_DATE(LASTDATE,'DD-MON-YYYY')  
  AND Alias3.ALAIS2_N_TRN_ID                         = Alias.Alias_N_PR  
  );  

COMMIT;  
END PROCEDURE_NAME;

错误：

第1行出错 ORA-02149：指定的分区不存在 ORA-06512：在“schema1.PROCEDURE_NAME”第17行 ORA-06512：第1行

我认为您可以通过动态SQL语句，EXECUTE IMMEDIATE语句

来完成

CREATE OR REPLACE PROCEDURE PROCEDURE_NAME (PARTITION_NAME IN VARCHAR2)  
     IS  
    LASTDATE VARCHAR2(12);  
ENDDATE VARCHAR2(12); 
query_str VARCHAR2(1000); 
BEGIN  
//.......your code.......
query_str := 'UPDATE TABLE_NAME PARTITION (' || PARTITION_NAME || ') Alias ' 
            ||'SET Alias.Alias_D_EFFECTIVE_DATE =.....'  

EXECUTE IMMEDIATE query_str;
COMMIT;  
END PROCEDURE_NAME;

希望这会奏效。
