JDBC SQL Server errors: ClassNotFound & Not Suitable Driver Found

I am very new to Java and am simply trying to connect to my MSSQL database and return a list of customers. When I try the JDBC connection, I get a "no suitable driver found" error. When I add a Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver") statement, I get a ClassNotFound error. This seems like it should be a lot easier than it's turning out to be. Please help me either find a suitable driver or how to get access through the Class.forName usage.

Connect Oracle Java stored procedure to Snowflake

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");
// build connection properties
Properties properties = new Properties();
properties.put("user", "XXX"); // replace "" with your username
properties.put("password", "XXXX"); // replace "" with your password
properties.put("account", "XXXX"); // replace "" with your account name
properties.put("db", "db1"); // replace "" with target database name
properties.put("schema", "MYSCHEMA"); // replace "" with target schema name
//properties.put("tracing", "on");
// create a new connection
String connectStr = null;//System.getenv("SF_JDBC_CONNECT_STRING");
// use the default connection string if it is not set in environment
if(connectStr == null)
{
connectStr = "jdbc:snowflake:XXXX"; // replace accountName with your account name
}
return DriverManager.getConnection(connectStr, properties);
}
}
How to import/integrate this driver for java stored procedure?

CData JDBC Couchbase Java app connection problem

I can't manage to get this right. I'm not sure of what is wrong. Apparently the connection is ok but can't get the result back of the query.
package probandoCouch;
import cdata.jdbc.couchbase.CouchbaseDriver;
import java.sql.Statement;
import java.util.Properties;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class App {
public static void main(String[] args) {
try {
Connection conn = DriverManager.getConnection(
"jdbc:couchbase:User=\"Administrator\";Password=\"Administrator\";Server=\"127.0.0.1\";");
Statement stat = conn.createStatement();
boolean ret = stat.execute("SELECT message FROM greeting WHERE author='foo';");
if (ret) {
ResultSet rs = stat.getResultSet();
while (rs.next()) {
for (int i = 1; i <= rs.getMetaData().getColumnCount(); i++) {
System.out.println(rs.getMetaData().getColumnName(i) + "=" + rs.getString(i));
}
}
}
} catch (SQLException e) {
}
}
}

Can you please remove semicolon(;) from query and try
SELECT message FROM greeting WHERE author='foo';
Updated Query:
SELECT message FROM greeting WHERE author='foo'
With semicolon jdbc will fail with error
java.sql.SQLException: ORA-00933: SQL command not properly ended
In your code you may print the exception to see if any exception is thrown.

Unable to get column name and column lable in sql server result set meta data

Can anybody help me to get actual column name and its alias using ResultSetMetaData by connecting to sqlserver database.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;
class MysqlCon {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=alcoa", "sa", "test");
Statement stmt = con.createStatement();
String query = "SELECT std_code as \"Student code\" from Student ";
ResultSet rs = stmt.executeQuery(query);
ResultSetMetaData rsm =rs.getMetaData();
for (int i = 1; i <= rsm.getColumnCount(); i++) {
System.out.println(rsm.getColumnLabel(i) + "--" + rsm.getColumnName(i));
}
} catch (Exception e) {
System.out.println(e);
} finally {
try {
con.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
output
Student code--Student code
Above code works as expected in other database like mysql and oracle.
I checked code for SQLServerResultSetMetaData. Both methods getColumnLabel and getColumnName are identical.
abzycdxw65, has raised same issue on their github account. it is closed.
Is there any way to get following output:
Student code--std_code

If I get your question you can try the followings to retrieve column names
select name from sys.columns

Statement st = conn.createStatement();
String str = "insert into trial values(1,'hello')";
st.execute(str);
System.out.println("Succes");
