工作脚本记录

create or replace procedure vip_update is
vip_update_sql varchar2(255); ---更新操作语句
vip_reback_sql varchar2(255); ---将以前的还原的语句
vip_users varchar2(32); ---这次需要更新的用户cursor vip_customer is

/ 单引号应用问题

PL/SQL中处理单引号

用两个连续的单引号可以转义成一个单引号字符
例：
declare
vc_name varchar2(100) :='shikai';
vc_str varchar2(100) ;
begin
dbms_output.put_line('hello, ' || 'shikai'); --输出hello, shikai
dbms_output.put_line('hello, ' || vc_name); --输出hello, shikai
dbms_output.put_line('hello, ' || '''shikai'''); --输出hello, 'shikai'
dbms_output.put_line('hello, ''' || 'shikai'||''''); --输出hello, 'shikai'
dbms_output.put_line('hello, ''' || vc_name||''''); --输出hello, 'shikai'
