Plsql 我在IS PLS-00103上出错:遇到符号“IS”

Plsql 我在IS PLS-00103上出错:遇到符号“IS”,plsql,Plsql,我在你的程序中发现了四个错误 首先,删除以下行末尾的两个分号: create or replace procedure seqn (sname IN seq.seqname%type , startv IN seq.startval%type , incby IN seq.incrementby%type , maxi IN seq.maxilimit%type ); IS s_count integer ; begin select count(*)

我在你的程序中发现了四个错误

首先,删除以下行末尾的两个分号:

create or replace procedure seqn (sname IN seq.seqname%type , 

startv IN seq.startval%type , 

incby IN seq.incrementby%type ,

 maxi IN seq.maxilimit%type );

     IS
s_count integer ;

    begin
    select count(*)
    into s_count
     from sequence;
     where seqname := sname ;
if s_count := 0
then
    insert into seq
    values(sname,startv,incby,maxi);
end if;

    end seqn ;
    /
从顺序; 其次,不要使用:=来比较下面两行中的值,而是使用=

 maxi IN seq.maxilimit%type );
     where seqname := sname ;
if s_count := 0
