我在 Sql 服务器 服务器 & amp; Mysql 中写了以下样本脚本
Sql ---->select len( Experts )
Result ---->7
MySql ---->select Length( Experts )
Result ---->8
现在,我对问题做了如下修改:
Sql ---->select len( Experts )
Result ---->8
MySql ---->select Length( Experts )
Result ---->8

SQL 服务器 < code> LEN 功能排除了文件所示的后退空间: http://msdn.microsoft.com/en-us/library/ms190329.aspx 。
如果您想要包含空格的长度, 请尝试 LEN( & lt; 源代码 & gt; + x) - 1 , 其中 < code@lt; 源代码 & gt; 是您试图获取的长度 。
