/** * sample1 JDBC sample application * * Sep 24 1997 JP * * This simple JDBC application does the following using * Solid native JDBC driver. * * 1. Registers the driver using JDBC driver manager services * 2. Prompts the user for a valid JDBC connect string * 3. Connects to Solid Server using the driver * 4. Creates a stament for one query, SELECT * FROM TABLES for * reading data from one of Solid Server's system tables. * 5. Executes the query * 6. Fetches and bups all the rows of a result set. * 7. Closes connection * * To build and run the application * * 1. Make sure you have a working Java Development environment * 2. Install and start Solid Server to connect. Ensure that the Server * is up and running. * 3. Append SolidDriver.zip into the CLASSPATH definition used * by your development/running environment. * 4. Create a java project based on the file sample1.java. * 5. Build and run the application. * * For more information read the readme.txt file contained by SolidDriver * package. * */ import java.io.*; public class sample1 { public static void main (String args[]) throws Exception { java.sql.Connection conn; java.sql.ResultSetMetaData meta; java.sql.Statement stmt; java.sql.ResultSet result; int i; System.out.println("JDBC sample application starts..."); System.out.println("Application tries to register the driver."); // this is the recommended way for registering Drivers java.sql.Driver d = (java.sql.Driver)Class.forName("solid.jdbc.SolidDriver").newInstance(); System.out.println("Driver succesfully registered."); // the user is asked for a connect string System.out.println("Now sample application needs a connectstring in format:\n"); System.out.println("jdbc:solid://<host>:<port>/<user name>/<password>\n"); System.out.print("\nPlease enter the connect string >"); BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String sCon = reader.readLine(); // next, the connection is attempted System.out.println("Attempting to connect :" + sCon); conn = java.sql.DriverManager.getConnection(sCon); System.out.println("SolidDriver succesfully connected."); String sQuery = "SELECT TABLE_SCHEMA,TABLE_NAME,TABLE_TYPE FROM TABLES"; stmt= conn.createStatement(); result = stmt.executeQuery(sQuery); System.out.println("Query executed and result set obtained."); // we get a metadataobject containing information about the // obtained result set System.out.println("Obtaining metadata information."); meta = result.getMetaData(); int cols = meta.getColumnCount(); System.out.println("Metadata information for columns is as follows:"); // we dump the column information about the result set for (i=1; i <= cols; i++) { System.out.println("Column i:"+i+" "+meta.getColumnName(i)+ "," + meta.getColumnType(i) + "," + meta.getColumnTypeName(i)); } // and finally, we dump the result set System.out.println("Starting to dump resultset."); int cnt = 1; while(result.next()) { System.out.print("\nRow "+cnt+" : "); for (i=1; i <= cols; i++) { System.out.print(result.getString(i)+"\t"); } } stmt.close(); conn.close(); // and not it is all over System.out.println("\nResult set dumped.
