Oracle存储过程：判断表中记录是否存在，存在则更新，不存在则插入！

 判断表CURRENTBRANCHSTATISTIC（总共两个字段BRANCH_ID,INNUM）中记录是否存在，存在则更新，不存在则插入！

 1 create or replace procedure CURRENTBRANCHSTATISTIC_INSERT(M_BRANCH_ID in NVARCHAR2,
 2  M_INNUM in NUMBER) is
 3  recordnum NUMBER:=0;
 4 begin
 5   select count(BRANCH_ID) into recordnum  from CURRENTBRANCHSTATISTIC Where BRANCH_ID=M_BRANCH_ID;
 6 if(recordnum=0) then
 7   insert into CURRENTBRANCHSTATISTIC(BRANCH_ID,INNUM) values (M_BRANCH_ID,M_INNUM);
 8 Else
 9   update CURRENTBRANCHSTATISTIC set INNUM=M_INNUM where BRANCH_ID=M_BRANCH_ID;
10 End if;
11 end CURRENTBRANCHSTATISTIC_INSERT;

调用代码：

1 begin
2   CURRENTBRANCHSTATISTIC_INSERT('111',198);
3   end;
