Guys, thanks very much for your invaluable help. I got my database to store perfectly with the prepared statement. Now I am wanting to find some data. Ok, I know you just do the query "SELECT * FROM "+tableName+" WHERE column_1 = '"+date+"'" this gives me everything but I want to store each columns value to a specific variable, so that I can send this to another class for display purposes.

Guys, thanks very much for your invaluable help.
I got my database to store perfectly with the prepared statement.
Now I am wanting to find some data.
Ok, I know you just do the query
"SELECT * FROM "+tableName+" WHERE column_1 = '"+date+"'"
this gives me everything
but I want to store each columns value to a specific variable, so that I can send this to another class for display purposes.
I wanted to iterate this to make it easier, this is what I have so far in a try and catch:
con = DriverManager.getConnection(dbURL, "","");
s = con.createStatement();
s.execute("SELECT * FROM "+tableName+" WHERE column_1 = '"+date+"'");
ResultSet rs = s.getResultSet(); // get any ResultSet that came from our query
boolean found = rs.next();
if (rs != null)
{
if(!found)
{
System.out.println("Nothing Found");
} //close if
else
{
for(int i = 0; i
<= 11; i++)
{
int j=i+2;
stringData ps.setString("SELECT column_'"+j+"' FROM "+tableName+" WHERE column_1 = '"+date"'");
getData[i] = stringData;
}
for(int j = 0; j
<= 4; j++)
{
//same as above but start at column_14 and save different primatives
}
}//close else
} //close if
but i get errors, not surprising since SQL is something I still need to fully learn. I think the prepared statement, is the wrong way to go, I was looking into the
ResultSet
but I cant seem to get this to work either.e.g.
String stringData = rs.getNString("column_2");
how can I get the data from the database?
