ORA-01745错误

ORA-01745: invalid host/bind variable name
Cause: A colon in a bind variable or INTO specification was followed by an inappropriate name, perhaps a reserved word.
Action: Change the variable name and retry the operation.

简而言之，你的sql语句有错误
网上google了一下，遇到这个错误的基本都是低级失误，比如少写了一个","，比如用系统关键字做字段名，比如在ibatis里把#xx#写成了##xx##，我今天遇到的是PreparedStatement里的sql语句，select xx from table where filed1 = ?for update，“?”和for连到一起了，多打一个空格就没问题了。最诡异的是测试的时候居然没错误！
