SQLException : query java.sql.SQLException: ORA-00911: invalid character

Question

Hi folks
I am not sure why this is happening. Only thing I can think of is field table_name has spaces then when I tried trim it does not like it.
Please help
Thanks a lot!
--------Here's the code ---------------
I have simple query (oracle database table names to extract and count the number of rows in each table) . This is the code snippet.
try {  // creating a table in the database
// querying mytable
String query;
query = "select table_name from user_tables;";
ResultSet rs = stmt1.executeQuery(query);
ResultSet rs1 =null;
Statement stmt2 = null;
while (rs.next())
System.out.println("table name : " + rs.getString(1) );
rs1 = stmt2.executeQuery("select count(*) from " + rs.getString(1));
} catch (SQLException e)
{ System.out.println("SQLException : query " + e);
}

Answer 1

ORA-00911 invalid character
Cause: Special characters are valid only in certain places. If special characters other than $, _, and # are used in a name and the name is not enclosed in double quotation marks (�), this message will be issued. One exception to this rule is for database names; in this case, double quotes are stripped out and ignored.
Action: Remove the invalid character from the statement or enclose the object name in double quotation marks.
So, I think you problem is a semicolon at then end of your query.
Hope this helps,
