Prepared statement Parameter index out of range (0 < 1 )

Question

Am not expert on web application, recently am writing a small webapp for my mobile app using servlets. My agenda is to receive data from client, and to put it into db. everything is running fine except, my database insert statement,which am trying to achieve using PreparedStatement.

// This is how my insert statement looks like
private String INSERT_INTO_DEVICES = "INSERT INTO travlemate.devices (owner,"
        + "deviceid,gcmid) VALUES (?,?,?)"; 

// This is how am trying to insert
PreparedStatement preparedStmt = mConn.prepareStatement(INSERT_INTO_DEVICES);
preparedStmt.setString(0, data.getDeviceNumber());
preparedStmt.setString(1, data.getDeviceID());
preparedStmt.setString(2,data.getGcmId());
preparedStmt.execute();
mConn.close();

but while executing this task, am receiving following exception

java.sql.SQLException: Parameter index out of range (0 < 1 ).

I seriously tried all sorts of thing which am capable of, but this exception is not going away, any idea on same?

Thanks, Techfist

Answer 1

PreparedStatement parameter indices start at 1

preparedStmt.setString(1, data.getDeviceNumber());
...

Answer 2

PreparedStatement preparedStmt = mConn.prepareStatement(INSERT_INTO_DEVICES);
preparedStmt.setString(1, data.getDeviceNumber());
preparedStmt.setString(2, data.getDeviceID());
preparedStmt.setString(3,data.getGcmId());
preparedStmt.execute();
mConn.close();

Jdbc parameters are not zero-indexed. It starts with 1 , as all the indexes in database related statements start with 1.
