Problem in inserting data into Oracle database using JDBC
I am trying to insert data using prepared statement in oracle 10g database but I am getting "SQL Exception:General Error" while executing the code given below. I think the problem is either with the DATE field or PASSWORD field data retrieval. Please Help me through this. Thanks.
Student Table:-
Sid VARCHAR2(200) PRIMARY KEY CHECK(Sid>0),
Pass_word VARCHAR2(10) NOT NULL,
S_name VARCHAR2(20) NOT NULL,
G_name VARCHAR2(20) ,
Branch VARCHAR2(10) NOT NULL,
D_company VARCHAR2(20) ,
B_Percent INT NOT NULL CHECK(B_Percent<100),
twelth_percent INT NOT NULL CHECK(twelth_percent<100),
tenth_percent INT NOT NULL CHECK(tenth_percent<100),
Certify VARCHAR2(30),
Semester INT NOT NULL CHECK(Semester<9),
D_Birth DATE NOT NULL,
Sex VARCHAR2(6) NOT NULL
Code:-
int bpercent ;
int twelthpercent;
int tenthpercent;
int semester;
String studentID = null;
String studentpassword = null;
String studentname = null;
String Gname = null;
String branch = null;
String dcompany = null;
String certify = null;
String sex = null;
Date date = new Date(00-00-0000);
Connection connection = null;
try {
// Load the JDBC driver
String driverName = "sun.jdbc.odbc.JdbcOdbcDriver";
Class.forName(driverName);
connection = DriverManager.getConnection("jdbc:odbc:placement","siddharth","sid");
studentID = StudentID.getText();
spassword = PasswordField.getPassword();
studentname = NameField.getText();
Gname = GuardianField.getText();
branch = BranchField.getText();
dcompany = DcompanyField.getText();
bpercent = Integer.parseInt(BtechField1.getText());
twelthpercent = Integer.parseInt(TwelthField.getText());
tenthpercent = Integer.parseInt(TenthField.getText());
semester =Integer.parseInt(SemesterField.getText());
certify = CertificationField.getText();
date = (Date) DateTextField.getValue();
sex = SexCombo.getActionCommand();
PreparedStatement state = connection.prepareStatement("insert into student " +"(sid,pass_word,s_name,g_name,branch,d_company,b_percent,twelth_percent,tenth_percent,certify,semester,d_birth,sex)"+
"values(?,?,?,?,?,?,?,?,?,?,?,?,?)");
state.setString(1, studentID);
state.setString(2, spassword.toString());
state.setString(3,studentname);
state.setString(4,Gname);
state.setString(5,branch);
state.setString(6,dcompany);
state.setInt(7,bpercent);
state.setInt(8,twelthpercent);
state.setInt(9,tenthpercent);
state.setInt(10,semester);
state.setString(11,certify);
state.setDate(1, new java.sql.Date(date.getTime()));
state.setString(12,sex);
state.executeUpdate();
state.close();
JOptionPane.showMessageD开发者_Go百科ialog(null,"Data Inserted","Information Messgage",JOptionPane.INFORMATION_MESSAGE);
connection.close();
}
catch (ClassNotFoundException e) {
// Could not find the database driver
JOptionPane.showMessageDialog(null,e);
}
catch (SQLException e) {
// Could not connect to the database
JOptionPane.showMessageDialog(null,e);
}
}
I believe you have a typo, you have:
state.setDate(1, new java.sql.Date(date.getTime()));
state.setString(12,sex);
And I think you want:
state.setDate(12, new java.sql.Date(date.getTime()));
state.setString(13,sex);
You've got certify and semester the wrong way round
In your insert sql string:
insert into (... tenth_percent,certify,semester,d_birth, ...)
in your
state.setInt(9,tenthpercent);
state.setInt(10,semester);
state.setString(11,certify);
state.setDate(12, new java.sql.Date(date.getTime()));
so it tries to set the semester column to a string, which is invalid.
Instead of using the lines:
`String driverName = "sun.jdbc.odbc.JdbcOdbcDriver";
Class.forName(driverName);`
Use the line:
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver);
Sometimes, the class cannot be read by the drivermanager, so you need to register the driver with the drivermanager.
Best of Luck!
Well! there was a mistake in the code... Instead:
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver);
Use:
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
