Prepared Statements in Application Programs. You can use server-side prepared statements through client programming interfaces, including the MySQL C API client library for C programs, MySQL Connector/J for Java programs, and MySQL Connector/NET for programs using.NET technologies. For example, the C API provides a set of function calls that make up its prepared statement API.
IN parameter placeholders autoGeneratedKeys - a flag indicating whether auto-generated keys should be returned; one of Statement.RETURNGENERATEDKEYS or Statement.NOGENERATEDKEYS Returns: a new PreparedStatement object, containing the pre-compiled SQL statement, that will have the capability of returning auto-generated keys Throws. When a new AUTOINCREMENT value has been generated, you can also obtain it by executing a SELECT LASTINSERTID statement with mysqlquery and retrieving the value from the result set returned by the statement. When inserting multiple values, the last automatically incremented value is returned. PreparedStatement with Statement.RETURNGENERATEDKEYS. Ask Question Asked 8 years. MySQL & Java - Get id of the last inserted value (JDBC) 12. Hibernate - Custom insert into database. SQLException - Generated keys not requested (MySQL) 3. Getting last auto increment value in. Connection.prepareStatement(sql-statement, Statement.RETURNGENERATEDKEYS);The following forms are valid only if the data source supports SELECT FROM INSERT statements. Sql-statement can be a single-row INSERT statement or a multiple-row INSERT statement. With the first form, you specify the names of the columns for which you want automatically generated keys.
What key combination generates a backspace character mean. This automatically sets up bash as the default shell.For historic reasons, all of the aliases and shortcuts I want to port from an old computer are in tcsh, and I don't really feel up to learning how to do the same in bash. Instead, I changed the login shell to tcsh, and I'm happy.The problem I have now is that backspace only deletes forward (like the del key), instead of backward (like ctrl+ h).

While creating a table, in certain scenarios, we need values to column such as ID, to be generated/incremented automatically. Various databases support this feature in different ways.
It is a decentralized digital currency without a central bank or single administrator that can be sent digitally from user-to-user on the peer-to-peer Bitcoin network without the need for intermediaries.A Bitcoin Address is an ID of 26-35 alphanumeric numbers, that represents a possible destination for an (incoming) Bitcoin payment for example to a Bitcoin Wallet. Generate private key and bitcoin address from xupb to computer.
In MySQL database you can declare a column auto increment using the following syntax.
While inserting records in a table there is no need to insert value under the auto-incremented column. These will be generated automatically.
For example, in a table if we have a column with name ID and data type INT, which is auto-incremented and, if we already have 6 records in that table. When you insert the next record using the INSERT statement the ID value of the new record will be 7 and the ID value of its next record will be 8.
(You can specify the initial value and interval for these auto-incremented columns).
Retrieving the auto-incremented values
If you insert records into a table which contains auto-incremented column, using a PreparedStatement object.
You can retrieve the values of that particular column, generated by the current PreparedStatement object using the getGeneratedKeys() method.
Example
Let us create a table with name sales in MySQL database, with one of the columns as auto-incremented, using CREATE statement as shown below −
Now, to insert records into this table using PreparedStatement object and, to retrieve the auto-incremented values generated by it −
- Register the Driver class of the desired database using the registerDriver() method of the DriverManager class or, the forName() method of the class named Class.
- Create a Connection object by passing the URL of the database, user-name and password of a user in the database (in string format) as parameters to the getConnection() method of the DriverManager class.
- Create a PreparedStatement object using the prepareStatement() method of the connection interface.
To this method pass the INSERT statement with bind variables in string format as one parameter and, Statement.RETURN_GENERATED_KEYS as other parameter as −

- Set values of each record to the bind variables using the setXXX() methods and, add it to batch.
After adding values of all the records to the batch, execute the batch using the executeBatch() method.
- Finally, get the auto-incremented keys generated by this PreparedStatement object using the getGeneratedKeys() method.
Following JDBC program inserts 5 records into the Sales table (created above) using PreparedStatement, retrieves and displays the auto-incremented values generated by it.
