从Oracle向SQL Server中间库交换数据的时候,出现了异常
com.microsoft.sqlserver.jdbc.SQLServerException: 将截断字符串或二进制数据
具体异常信息如下:

在网上搜罗了一下,大概有几种原因会导致此异常

字段长度不够

有trigger处理业务逻辑
这次遇到的就是字段长度不够的问题,SQL Server中定义的长度为24,而Oracle中定义的长度为50,修改字段长度,问题解决
判断长度相关SQL语句如下:以字符串“某餐证字20112101230000159”为例
SQL Server中查询的SQL语句
select len('某餐证字20112101230000159'),datalength('某餐证字20112101230000159');
长度为21,占用25个字节
Oracle中查询的SQL语句
select length('某餐证字20112101230000159'), lengthb('某餐证字20112101230000159') from dual;
长度为21,占用25个字节
