问题
I'm new to JDBC. I want to insert data into Access from Java, but I can't get it. It shows the following error:
Connection Established Successfully
java.sql.SQLException: General error
Could Not Connect to Database
at sun.jdbc.odbc.JdbcOdbc.createSQLException(Unknown Source)
at sun.jdbc.odbc.JdbcOdbc.standardError(Unknown Source)
at sun.jdbc.odbc.JdbcOdbc.SQLExecDirect(Unknown Source)
at sun.jdbc.odbc.JdbcOdbcStatement.execute(Unknown Source)
at sun.jdbc.odbc.JdbcOdbcStatement.executeUpdate(Unknown Source)
at DBConnect.<init>(DBConnect.java:22)
at DBConnect.main(DBConnect.java:32)
code:
public DBConnect() {
File f = new File("DB.accdb");
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("DriverLoaded");
String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" + f.getAbsolutePath();
Connection con = DriverManager.getConnection(url);
System.out.println("Connection Established Successfully");
Statement st=con.createStatement();
String productId="1";
String desc="Jambu";
int quantity=10;
double price = 2.0, disc=1.0;
st.executeUpdate("INSERT into Product(productID,description,quantity,price,discount) VALUES('"+productId+"','"+desc+"','"+quantity+"','"+price+"','"+disc+"')");
System.out.println("Row is added");
}catch(Exception e) {
e.printStackTrace();
System.out.println("Could Not Connect to Database");
}
回答1:
you have not installed driver for MSAccess properly..
For example try like this..
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); // set this to a MS Access DB you have on your machine
String filename = "d:/DB.accdb";
String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=";
database+= filename.trim() + ";DriverID=22;}"; // add on to the end
// now we can get the connection from the DriverManager
Connection con = DriverManager.getConnection( database ,"","");
And also make sure that you have import jar file of ODBC driver in your path..
Update :
Insert data like this..
PreparedStatement pstmt = (PreparedStatement) con.prepareStatement("insert into product(productID,description,quantity,price,discount) values(?,?,?,?,?)");
pstmt.setString(1, productId);
pstmt.setString(1, desc);
//same for all statement
pstmt.executeUpdate();
pstmt.close();
