com.microsoft.sqlserver.jdbc.SQLServerException: 索引 2 超出范围:(

Question

I have following code in java

qry="insert into usr_auth(usrid,username,password,email) values(?,?,?,?)";
            ps=con.prepareStatement(qry);
            ps.setString(1,getUniqueID());
            ps.setString(2,newUp.getUsrName());
            ps.setString(3,newUp.getPwd());
            ps.setString(4,newUp.getEmail());
            ps.executeUpdate();

this code is giving me an IndexOutOfBoundsException as:

Database Exception Occured

In database I have 4 columns usrid, username, password, email

username is of nvarchar(MAX) type.

Everything seems fine but I am still getting this exception why?? [The line 55 in stacktrace is the line ps.setString(2,newUp.getUsrName());]

Answer 1

Not directly related to your issue but it is possible to get this error if you miss a single quote somewhere when using XQuery within SQL. I had this with the following SQL:

UPDATE TABLE SET CustomFields.modify('replace value of (/CustomFields/Field[@ID=1]/Value)[1] with "HELLO WORLD!") WHERE ID=?

It needed to be

UPDATE TABLE SET CustomFields.modify('replace value of (/CustomFields/Field[@ID=1]/Value)[1] with "HELLO WORLD!"') WHERE ID=?

(single quote missing after with "HELLO WORLD!")

So the exception in my case was the wrong exception thrown by the SQL driver.
