Oracle存儲過程：判斷表中記錄是否存在，存在則更新，不存在則插入！

 判斷表CURRENTBRANCHSTATISTIC（總共兩個字段BRANCH_ID,INNUM）中記錄是否存在，存在則更新，不存在則插入！

create or replace procedure CURRENTBRANCHSTATISTIC_INSERT(M_BRANCH_ID in NVARCHAR2,
 M_INNUM in NUMBER) is
 recordnum NUMBER:=0;
begin
  select count(BRANCH_ID) into recordnum  from CURRENTBRANCHSTATISTIC Where BRANCH_ID=M_BRANCH_ID;
if(recordnum=0) then
  insert into CURRENTBRANCHSTATISTIC(BRANCH_ID,INNUM) values (M_BRANCH_ID,M_INNUM);
Else
  update CURRENTBRANCHSTATISTIC set INNUM=M_INNUM where BRANCH_ID=M_BRANCH_ID;
End if;
end CURRENTBRANCHSTATISTIC_INSERT;

調用代碼：

begin
  CURRENTBRANCHSTATISTIC_INSERT('111',198);
  end;
