数据库为Oracle 9i ,数据库表名为TABLEMQ,包括两个字段:ID (Type 为 VARCHAR2(200)),MESSAGE (Type 为 VARCHAR2(200))
设置断点调试,传入值 tempID = "ID:414d5120514d5f303030303030303020f3f51b4720000e01"
message = "hello world"
执行至stmt.executeUpdate(strSQL);处提示错误为:
java.sql.SQLException: ORA-01008: 并非所有变量都已关联
实在查不出错误,望各位不吝赐教!多谢!
------解决方案--------------------
把你这句
stmt.executeUpdate(strSQL);
里面的strSQL去掉,改成
stmt.executeUpdate();
应该是这里了!!!
