大神 帮忙看看执行存储过程的时候为什么报对象无效
create or replace procedure xh_procedure_1(x_sex in userinfo.sex%type) as
x_count number;
begin
if x_sex = 'M' then
select count(*) into x_count from userinfo where sex = 'M';
dbms_output.put_line(x_count);
else
x_sex = 'F' then
select count(*) into x_count from userinfo where sex = 'F';
dbms_output.put_line(x_count);
end if;
end xh_procedure_1;
begin
xh_procedure_1('M');
end;
对象xh_procedure_1无效
------解决方案-------------------- if x_sex = 'M' then
select count(*) into x_count from userinfo where sex = 'M';
dbms_output.put_line(x_count);
elsif
x_sex = 'F' then
select count(*) into x_count from userinfo where sex = 'F';
dbms_output.put_line(x_count);
另外为什么不用where sex=x_sex
