sQL语句不正确 哥哥们呀来呀

[pipiws8]

try
{

connect1 = DriverManager.getConnection("jdbc:odbc:words");
sql1 = connect1.createStatement();
long i=(int)Math.random()*8845;

rset1 = sql1.executeQuery("SELECT * FROM words where number=i");
while(rset1.next())
tfAnswer.setText(rset1.getString(3));
}catch (SQLException e)
{
tfAnswer.setText("SQLException when open!\n");
}

怎么不能正确执行呀
出异常了rset1 = sql1.executeQuery("SELECT * FROM words where number=i");
就这条语句不知道弄了number=i就不对呢
这样rset1 = sql1.executeQuery( "SELECT * FROM words where number= "+i+ " ");还是不行呀；没有结果出来

[masse]

rset1 = sql1.executeQuery("SELECT * FROM words where number="+i);

[pipiws8]

rset1 = sql1.executeQuery("SELECT * FROM words where number="+i);
我用国了呀

[tanglei323]

rset1 = sql1.executeQuery("SELECT * FROM words where number="+i);
是正确的。
