Inserting value into table in java - java

I am new to java and trying to learn to insert the username and password and a profile image path into a Mysql database. When I run the following code, it will insert into table but the path filed of the table 'table_profile' 3rd column like as follows
if path equals "C:/Users/Manohar/Documents/FileUplaodDemo/build/web/uploads/x.jpg"
then it is inseerted as path equals "C:UsersManoharDocumentsFileUplaodDemo uildwebuploads
stmt = connection.prepareStatement(
"insert into table_profile values('"+userId+"','"+userName+"','"+path+"')");

User parameter binding like this:
stmt = connection.prepareStatement("insert into table_profile values(?, ?, ?)");
stmt.setInt(1, userId);
stmt.setString(2, userName);
stmt.setString(3, path);
Let Java do all the hard work for you :)

Java MS SQL Select inside Insert

I want to insert 5 datas into one SQL table, the last four of which are already working and fine, but the first one should be from another table, a String, giving an Int to the table in which im inserting it. And this is my solution so far. However i'm still getting an error:
"The index 5 is out of range."
PreparedStatement stmt = connection.prepareStatement("INSERT INTO RECORDS (LocationId, RecId, RecValues, YearTime, HourTime) VALUES " +
"((SELECT LocationId from Locations where Location_name = 'Mic HR1'), ?, ?, ?, ?)");
stmt.setInt(1,1);
stmt.setInt(2, recid);
stmt.setInt(3, inputData);
stmt.setDate(4, sqlDate);
stmt.setTime(5, Time.valueOf(dtf.format(now)));
stmt.executeUpdate();
Actually you have only four parameters defined on your query, because LocationId is being calculated by the inner select you provided. That's why you are getting the error.
Try this:
PreparedStatement stmt = connection.prepareStatement("INSERT INTO RECORDS (LocationId, RecId, RecValues, YearTime, HourTime) VALUES " +
"((SELECT LocationId from Locations where Location_name = 'Mic HR1'), ?, ?, ?, ?)");
stmt.setInt(1, recid);
stmt.setInt(2, inputData);
stmt.setDate(3, sqlDate);
stmt.setTime(4, Time.valueOf(dtf.format(now)));
stmt.executeUpdate();

MySQL INSERT INTO doesn't work but gives no error

I'm having trouble inserting a row into a MySQL table with Java. I'm not sure what the problem is as it isn't giving an error. I'm trying to insert the row with the following:
String sql = "INSERT INTO users (uuid, authKey, code, scratches) VALUES (?, ?, ?, ?);";
PreparedStatement insertStmt = connection.prepareStatement(sql);
insertStmt.setString(1, uuid);
insertStmt.setString(2, key);
insertStmt.setInt(3, code);
insertStmt.setString(4, getScratchString());
insertStmt.executeUpdate();
The table 'users' is created successfully with no errors with the following:
Statement stmt = connection.createStatement();
stmt.executeUpdate("CREATE TABLE IF NOT EXISTS users (uuid VARCHAR(40), authKey VARCHAR(30), code INT(10), scratches VARCHAR(45));");
When trying to insert the row with the same update in phpmyadmin, it works fine. There is no error given by the update so I have no idea where to start debugging. Any help would be appreciated. Thanks.
You have to do commit transaction check the below code
String sql = "INSERT INTO users (uuid, authKey, code, scratches) VALUES (?, ?, ?, ?)";
PreparedStatement insertStmt = connection.prepareStatement(sql);
insertStmt.setString(1, uuid);
insertStmt.setString(2, key);
insertStmt.setInt(3, code);
insertStmt.setString(4, getScratchString());
insertStmt.executeUpdate();
connection.commit();

MySQL SQL Syntax error on GUI

Hello I want to put 2 values to 2 columns in my table. I get those values from txtField and textField_1 (which are 2 textboxes on an GUI).
The problem is that whenever I push the button to register those values I get an syntax error on my mysql.
String query = "INSERT INTO Registration (Username , Password ) VALUES (? ,?)";
java.sql.PreparedStatement pst = connection.prepareStatement(query);
pst.setString(1,textField.getText());
pst.setString(2,textField_1.getText());
int rs = pst.executeUpdate(query);
If I put static values instead of ?, is working.
String query = "INSERT INTO Registration (Username , Password ) VALUES (? ,?)";
java.sql.PreparedStatement pst = connection.prepareStatement(query);
pst.setString(1,textField.getText());
pst.setString(2,textField_1.getText());
int rs = pst.executeUpdate();
use executeUpdate()

Syntax error in Prepared statement while inserting into db

Hi I am trying insert data into the database using prepared statement but I am getting syntax error could u please help
public boolean SignUp(String last_name, String first_name,String email, String password,String confirm_password,String phone){
Connect connect = new Connect();
Connection conn = connect.Connection();
java.sql.PreparedStatement preparedStatement = null;
//NULL is the column for auto increment
String insertQuery = "INSERT INTO users VALUES (NULL, ?, ?, ?, ?, ?, ?)";
preparedStatement = conn.prepareStatement(insertQuery);
preparedStatement.setString(1, last_name);
preparedStatement.setString(2, first_name);
preparedStatement.setString(3, email);
preparedStatement.setString(4, password);
preparedStatement.setString(5, confirm_password);
preparedStatement.setString(6, phone);
int rs = preparedStatement.executeUpdate(insertQuery);
conn.close();
}
here is the error message
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?, ?, ?, ?, ?, ?)' at line 1
I found the answer :)
Use preparedStatement.execute() instead of executeUpdate(sql). You have already set the sql and params - the new setting in executeUpdate(sql) overrides the bind.
You should change the statement to list the columns explicitly, and drop NULL from the list of values.
String insertQuery = "INSERT INTO users"
+ " (last_name, first_name, email, password, confirm_password, phone)"
+ " VALUES(?,?,?,?,?,?)";
This way your insert statement is no longer dependent on the order of columns in your users table, and is also immune to addition of columns to the table.
Note that although this design is probably OK for a toy or an education system, but in a real production system storing password in a table is very dangerous. Storing confirm_password is rather unusual, too: normally your system checks that password is the same as confirm_password, and then inserts a salted password hash and a salt into the table.
Just a guess, not I'm not certain. But if one of the fields is autoincrement, then I don't think you need to insert it. Try taking out that NULL....

Error while inserting using JDBC prepared statement

I am trying to insert some values into Oracle DB from Java using the following JDBC statement:
String SQL_PREP_INSERT = "INSERT INTO ABC.TEST (LOG_ID, SESSION_ID,USER_ID) VALUES"
+ " (ABC.logid_seq.nextval, ?, ?)";
stmt = con.prepareStatement(SQL_PREP_INSERT);
stmt.setString(1, sessionId);
stmt.setString(2, userid);
stmt.execute();
stmt.close();
The sequence is created as follows:
create sequence ABC.logid_seq
minvalue 1 maxvalue 9999999999999999999999
increment by 10 start with 10 cache 20 noorder nocycle ;
I am getting the following error,
java.sql.SQLException: ORA-00942: table or view does not exist
But when I try to insert into the table manually, it's successful.
insert into ABC.test(LOG_ID,SESSION_ID,USER_ID) values
(VZPPTL.logid_seq.nextval,'test_session', '001');
What's the problem?
Possibly looking at the wrong table or database. Are you sure your looking at the right database from the code?
In prepare statement no need to give schema name(In this case ABC).
Try this, it might work.
String SQL_PREP_INSERT = "INSERT INTO TEST (LOG_ID, SESSION_ID,USER_ID) VALUES"
+ " (logid_seq.nextval, ?, ?)";
