EXECUTE IMMEDIATE 'SELECT COUNT (*) INTO v_count from br_'||quhao ||' WHERE instr(br_number, '||v_br_number||')>0 OR br_company ='|| v_br_company;
……
最后的 EXECUTE IMMEDIATE 那个sql语句 由于v_br_number，v_br_company是varchar型 要执行的sql要加单引号 请问要怎么写才对？{{----}

我对SQL SERVER和ACCESS比较熟，所以数据库的通用基础东西可以说都掌握的差不多了，我现在想要的就是以上两数据库的独特之处的介绍和应用介绍。
另外书最好对应最新版本 oracle是11g吧 10的也行；mysql是5.1吧
