I was trying to have snowflake db connection using oracle Java stored procedure. But it's giving me error
ORA-29532: Java call terminated by uncaught Java exception: java.sql.SQLException: No suitable driver found
I have already downloaded snowflake-jdbc-3.6.19-javadoc.jar from related source.
Below is sample code of java class which will be called from oracle java procedure.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;
public class SnowflakeDriverExample
{
public static void testdata() throws Exception
// public static void main(String[] args) throws Exception
{
// get connection
System.out.println("Create JDBC connection");
Connection connection = getConnection();
System.out.println("Done creating JDBC connectionn");
// create statement
System.out.println("Create JDBC statement");
Statement statement = connection.createStatement();
System.out.println("Done creating JDBC statementn");
// query the data
System.out.println("Query demo");
ResultSet resultSet = statement.executeQuery("SELECT DATA_ID FROM TEMP_TABLE");
System.out.println("Metadata:");
System.out.println("================================");
// fetch metadata
ResultSetMetaData resultSetMetaData = resultSet.getMetaData();
System.out.println("Number of columns=" +
resultSetMetaData.getColumnCount());
statement.close();
}
private static Connection getConnection()
throws SQLException
{
try
{
Class.forName("net.snowflake.client.jdbc.SnowflakeDriver");
}
catch (ClassNotFoundException ex)
{
System.err.println("Driver not found");
}
// Class.forName("net.snowflake.client.jdbc.SnowflakeDriver");

properties.put("user", "XXX"); // replace "" with your username

How to import/integrate this driver for java stored procedure?
I am using Netbeans to make a POS system and I am trying to insert values into an H2 table.The database connection seems to function properly and the table exists but I keep getting the table not found error. Here is my code to make the connection
package h2finalproj;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import javax.swing.JOptionPane;
/**
*
* #author Connor Hicks
*/
public class HDBConnect {
public static Connection connDB()
{
try {
Class.forName("org.h2.Driver");
Connection conn=DriverManager.getConnection("jdbc:h2:~\\cghicks1 [ database];","cghicks1","");
return conn;
} catch (ClassNotFoundException | SQLException e) {
JOptionPane.showMessageDialog(null, e);
}
return null;
}
}
public class H2FinalProj extends javax.swing.JFrame {
Connection connect = null;
ResultSet rst=null;
PreparedStatement pst=null;
PreparedStatement crt = null;
public H2FinalProj() {
initComponents();
connect = HDBConnect.connDB();
}
Here is my code to insert values:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)
try {
String sql;
sql = "INSERT INTO \"PUBLIC\".INVENTORY (PRODNUM, PRODNAME, PRICE, STOCK) values(?,?,?,?)";
pst = connect.prepareStatement(sql);
pst.setString(1, prodNum2.getText());
pst.setString(2,prodName2.getText());
pst.setString(3, price2.getText());
pst.setString(4, numStock2.getText());
pst.execute();
JOptionPane.showMessageDialog(null, "Success !");
} catch (SQLException | HeadlessException e) {
JOptionPane.showMessageDialog(null, e);
}
}
And the error I am receiving looks something like this:
SQL Exception Table "Inventory not found" [42102-190]
I have found somewhat similar questions and solutions but nothing that seems to be close or clear enough to solve this problem.
This question has a problem description which is extremely similar to mine however both my application and console are already using 1.4, so the solution does not seem to help me.
Embedded h2 database: getting connection but table not found
How might I solve this?
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.Statement;
public class Create
{
public static void main( String [] args)throws Exception
{
Connection con=DriverManager.getConnection("jdbc:oracle:thin:#localhost:1522/orcl1","scott","sada");
System.out.println("connection is createad");
Statement stmt=con.createStatement();
System.out.println("statemnt of object is createad");
stmt.executeUpdate("create table iteam(iteamno number(3)primarykey,iteamname number(15),price number(4))");
System.out.println("table is created ");
con.close();
stmt.close();
System.out.println("conncetion closed");
}
}
Every thing executed successfully but after Statement object it will show this error when my program executes:
java.sql.SQLSyntaxErrorException: ORA-00907: missing right parenthesis
Error
A spacing error. Fixed below; you'd do well to try your statements in a fiddle before posting a question here, #sada:
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.Statement;
public class Create
{
public static void main( String [] args)throws Exception
{
Connection con=DriverManager.getConnection("jdbc:oracle:thin:#localhost:1522/orcl1","scott","sada");
System.out.println("connection is createad");
Statement stmt=con.createStatement();
System.out.println("statemnt of object is createad");
stmt.executeUpdate("create table iteam(iteamno number(3) primary key,iteamname number(15),price number(4))");
System.out.println("table is created ");
con.close();
stmt.close();
System.out.println("conncetion closed");
}

I use Netbeans, doing a java app. I created a class ConnectDB for db connetion using Java DB in netbeans. i started the server and ten conneted to db. when i run the file it produce
java.lang.ClassNotFoundException: org.apache.derby.jdbc.ClientDriver # 25 line
and
java.sql.SQLException: No suitable driver found for jdbc:derby://localhost:1527/Libraryprj;create=true
#30 th line of code
the code is below
package Lms;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;
/**
*
* #author JOJO

public class ConnectDB {
static Connection conn;
public static void main(String[] args) {
String driver = "org.apache.derby.jdbc.ClientDriver";
String connectionURL = "jdbc:derby://localhost:1527/Libraryprj;create=true";
String createString = "CREATE TABLE Employee (NAME VARCHAR(32) NOT NULL, ADDRESS VARCHAR(50) NOT NULL)";
try {
Class.forName(driver);
} catch (java.lang.ClassNotFoundException e) {
e.printStackTrace();
}
try {
conn = DriverManager.getConnection(connectionURL);
Statement stmt = (Statement) conn.createStatement();
stmt.executeUpdate(createString);
PreparedStatement psInsert = conn.prepareStatement("insert into Employee values (?,?)");
psInsert.setString(1, args[0]);
psInsert.setString(2, args[1]);
psInsert.executeUpdate();
Statement stmt2 = (Statement) conn.createStatement();
ResultSet rs = stmt2.executeQuery("select * from Employee");
int num = 0;
while (rs.next()) {
System.out.println(++num + ": Name: " + rs.getString(1) + "\n Address" + rs.getString(2));
}
rs.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
get this library
http://repo.maven.apache.org/maven2/org/apache/derby/derbyclient/10.9.1.0/derbyclient-10.9.1.0.jar
and copy it to Derby's libs folder.
If you use Tomcat download derbyclient.jar from here . And copy the jar file to Tomcat's lib folder.

Never tried it but seems like OpenOffice uses HSQLDB database underneath in file mode. Looks like you can connect to this HSQLDB database directly: Java: Creating a JDBC Connection to OpenOffice.Org Databases.
