如果在PL中再次输入相同SAP_ID的数据，则更新表SQL

Question

我有一个SP，其中我已将inserting记录的逻辑写入表中。但是现在如果用户再次输入记录_对于相同的SAP_ID，则我想更新该记录。

那么如何再次添加相同的SAP_ID更新记录？

下面是我的存储过程： -

PROCEDURE INSERT_INTO_EXIST_SAPID 
    (
P_SAPID IN NVARCHAR2, 
P_VENDOR_NAME IN NVARCHAR2, 
P_ODU_MODEL IN NVARCHAR2, 
P_ANT_MODEL IN NVARCHAR2, 
P_OMT_MODEL IN NVARCHAR2, 
P_QUANTITY IN NVARCHAR2, 
P_CREATED_BY IN NVARCHAR2, 
P_CREATED_DATE IN NVARCHAR2, 
P_IS_EXISTSAP IN CHAR, 
PREQUEST_ID OUT NUMBER  
) 

AS BEGIN 

INSERT INTO UBR_STRUCTURE_DETAILS 
            (
            RJ_SAPID, 
            VENDOR_NAME, 
            ODU_EQP_MODEL, 
            ANT_EQP_MODEL, 
            OMT_EQP_MODEL, 
            MODEL_COUNT, 
            CREATED_USER, 
            CREATED_DATE, 
            EXIST_SAPID 
           ) 
     VALUES 

           (
            P_SAPID, 
            P_VENDOR_NAME, 
            P_ODU_MODEL, 
            P_ANT_MODEL, 
            P_OMT_MODEL, 
            P_QUANTITY, 
            P_CREATED_BY, 
            SYSDATE, 
            P_IS_EXISTSAP 
           )returning REQUEST_ID INTO PREQUEST_ID; 
END INSERT_INTO_EXIST_SAPID;

你可以使用MERGE声明：

MERGE INTO UBR_STRUCTURE_DETAILS trg 
USING (SELECT P_SAPID, 
       P_VENDOR_NAME, 
       P_ODU_MODEL, 
       P_ANT_MODEL, 
       P_OMT_MODEL, 
       P_QUANTITY, 
       P_CREATED_BY, 
       SYSDATE, 
       P_IS_EXISTSAP 
     FROM dual) src 
    ON trg.<col_to_match> = src.<col_to_match> 
WHEN MATCHED THEN 
     UPDATE SET 
      col_name = src.col_name 
WHEN NOT MATCHED THEN 
     INSERT (col_list) 
     VALUES (...);
