If you want to get the desc (description) of a table using Java JDBC, you can do that by running a Statment query,
Query:desc students;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
public class JDBCTableDescExample {
public static void main(String[] args) throws ClassNotFoundException, SQLException {
String url ="jdbc:mysql://localhost:3306/my_uat";
String userName="root";
String password ="root123";
String insertQuery ="desc students";
Connection connection = DriverManager.getConnection(url,userName,password);
PreparedStatement preparedStatement = connection.prepareStatement(insertQuery);
ResultSet rs = preparedStatement.executeQuery();
ResultSetMetaData resultSetMetaData = rs.getMetaData();
int colCount = resultSetMetaData.getColumnCount();
for(int i=1;i<=colCount;i++) {
System.out.print(resultSetMetaData.getColumnName(i)+"\t |");
}
System.out.println("");
while(rs.next()) {
for(int i=1;i<=colCount;i++) {
System.out.print(rs.getString(i)+"\t |");
}
System.out.println("");
}
}
}
Output:
Field |Type |Null |Key |Default |Extra |
student_id |int |NO |PRI |null |auto_increment |
student_name |varchar(45) |NO | |null | |
student_dob |datetime |NO |PRI |null | |
student_address |varchar(45) |NO | |null | |
