在PB开发过程中,由于数据库中使用了 ntext字段,出现以下提示错误,郁闷了很长时间找不到解决方案,后查阅大量资料,终于明白:
PB报错: 不能用 DB-Library(如 ISQL)或 ODBC 3.7 或更早版本将 ntext 数据或仅使用 Unicode 排序规则的 Unicode 数据发送到客户端。

由于sql server中,ntext和nvarchar字段是用unicode编码存储内容的,因此php通过mssql扩展读取带ntext和nvarchar类型字段的时候会抱错。
如果 title 字段类型为 nvarchar,content 字段类型为 ntext ,那么下面的sql语句会报错:
代码如下 | 复制代码 |
select title,content from article where 1 |
正确的写法是:
代码如下 | 复制代码 |
select convert(varchar(255),title) as title, convert(text,content) as content from article where 1 |
或者不使用ntext字段
