一、系统表结构
<%
int tableNum = 0;
int tableSuffix = 0;
querySql = "select count(*) from all_tab_comments t where t.owner='" + DBUserName + "' and t.table_type='TABLE'";
rs = cn.executeQuery(querySql);
rs.next();
tableNum = rs.getInt(1);
rs.close();
String tableName[] = new String[tableNum];
String comments[] = new String[tableNum];

querySql = "select t.*, rownum from all_tab_comments t where t.owner='" + DBUserName + "' and t.table_type='TABLE' order by table_name";
rs = cn.executeQuery(querySql);
while(rs.next()){
tableName[tableSuffix] = rs.getString("TABLE_NAME");
comments[tableSuffix] = rs.getString("COMMENTS");
%>
<%
tableSuffix++;
}
rs.close();
%>

二、用户表结构
<%
}
%>

"><%=i+1%>、<%=tableName[i]%>（<%=comments[i]%>）
<%
querySql = "select t.column_name, t.COMMENTS, t1.data_type, t1.data_length, t1.nullable, rownum from all_col_comments t, all_tab_cols t1 where t.column_name = t1.column_name and t.table_name = t1.table_name and t1.owner='" + DBUserName + "' and t.owner = t1.owner and t.TABLE_NAME = '" + tableName[i] + "' order by t1.COLUMN_ID ";
rs = cn.executeQuery(querySql);
while(rs.next()){

<%
}
rs.close();

三、视图
<%
querySql = "select t.*, rownum from all_tab_comments t where t.owner='" + DBUserName + "' and t.table_type='VIEW' order by rownum desc ";
rs = cn.executeQuery(querySql);
while(rs.next()){

四、索引
<%
querySql = "select t.*, rownum from all_indexes t where t.table_owner='" + DBUserName + "' order by rownum desc ";
rs = cn.executeQuery(querySql);
while(rs.next()){

%>
<%

}
finally{
con.close();
}
