result set type is TYPE_FORWARD_ONLY_token odbc
Java调用存储过程的时候,总是报result set type is TYPE_FORWARD_ONLY 的错误驱动是通过odbc数据源来实现的
而改用jdbc直连的话这个问题就没有了
前提是结果集的类型我已经设置成 result.TYPE_SCROLL_INSENSITIVE的类型了,
还有就是 sql server2000 的 sp4补丁我已经打过了,但是有的java项目直连sqlserver2000 的时候还是会报 error esblishing socket 错误

有没有类似
rs.last()
int i = rs1.getRow();
的代码?
1这是你定义指针类型的时候只定义成了,向前移动的类型.
2设定结果集回滚.
connect=dataSource.getConnection();
Statement stmt=connect.createStatement();
ResultSet rs=stmt.executeQuery(strSql);
rs.last（）;
这样写之后会报rs.last（）有错,后来看到last()方法：
Throws:
SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY
后来查明原因果然是因为the result set type is TYPE_FORWARD_ONLY,查明的具体过程是：System.out.println(rs.getType());看到打印出来的结果是1003,后到JDK的src里面查到int TYPE_FORWARD_ONLY = 1003;这句话,说明the result set type is TYPE_FORWARD_ONLY.
那么解决办法就是要把the result set type 不要设成 TYPE_FORWARD_ONLY,后来在网上查到解决办法是：
connect=dataSource.getConnection();
Statement stmt=connect.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
//Statement stmt=connect.createStatement(1004,1007);
ResultSet rs=stmt.executeQuery(strSql);
rs.last（）;
