oracle存储过程中使用字符串拼接

1、使用拼接符号“||”

v_sql := \'SELECT * FROM UserInfo WHERE ISDELETED = 0 AND ACCOUNT =\'\'\' || vAccount || \'\'\' AND PASSWORD = \'\'\' || vPassword || \'\'\'\';

2、使用ASCII码拼接

v_sql := \'SELECT * FROM UserInfo WHERE ISDELETED = 0 AND ACCOUNT =\' ||chr(39)||vAccount||chr(39)||\' AND PASSWORD = \'||chr(39)||vPassword||chr(39);
