I am trying to connect to a MySQL database from a jsp page using jdbc in the backend.
I have the following code:
public static void insertIntoDatabase(String code,String name,String temp,String hum,String del) {
Connection con = null;
if (del.length() == 0) {
del="no data";
}
name = name.replaceAll("\\(.+?\\)", "");
name = name.replaceAll(" ", "_");
del = del.replaceAll(" ", "_");
System.out.println("del "+del);
String url = "jdbc:mysql://localhost:3306/test";
try {
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection(url,"root","");
con.createStatement().executeUpdate("CREATE TABLE IF NOT EXISTS aiportdetails(code VARCHAR(50) PRIMARY KEY, " +
"name VARCHAR(250), temp VARCHAR(50), hum VARCHAR(50), del VARCHAR(50))");
ResultSet rs = con.prepareStatement("SELECT * FROM airportdetails;").executeQuery();
} catch (SQLException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} finally {
try {
if (con != null) {
con.close();
}
} catch (SQLException ex) {
ex.printStackTrace();
}
}
}
I am getting the following error at
ResultSet rs = con.prepareStatement("SELECT * FROM airportdetails;").executeQuery();
error:
Table 'test.airportdetails' doesn't exist
But from my phpmyadmin I can see that the table is created and exists:
What is the reason I am getting this error?
Thank you.
Executes the SQL statement in this PreparedStatement object, which must be an SQL INSERT
, UPDATE
or DELETE
statement; or an SQL statement that returns nothing, such as a DDL statement.
Currently you are trying to use this for creating a table. That's the reason why you are getting that error.
Refer to the documentation Java 6 OR Java 1.4.2 for executeUpdate
You should create a table using Statement
Statement st = con.createStatement();
String table = "Create table .......";
st.executeUpdate(table);
