As shown above, we're telling the JDBC to return the value of id column after executing the given query. Similar to the previous example, we can fetch the id afterward: try ( ResultSet keys = statement.getGeneratedKeys()) {. assertThat(keys.next()).isTrue(); assertThat(keys.getLong( 1 )).isGreaterThanOrEqualTo( 1 );

Autogenerated keys
A constant indicating that auto-generated keys should be made available. The specific constant to use is Statement.RETURN_GENERATED_KEYS. An array of the names of the columns in the inserted row that should be made available.
How to Retrieve Auto-Generated Keys in Jdbc
As the first step, we have to pass the Statement.RETURN_GENERATED_KEYS to the prepareStatement() method: try (Connection con = DriverManager. getConnection(url, user, password); PreparedStatement pst = con. prepareStatement(sql, Statement. RETURN_GENERATED_KEYS)) Then we retrieve the generated key(s) with the getGeneratedKeys() method: ...
Retrieving auto-generated keys for an INSERT statement
Statement.executeUpdate(sql-statement, Statement.RETURN_GENERATED_KEYS);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.
Statement (Java Platform SE 8 )
The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1 ...
PreparedStatement (Java Platform SE 8 )
A SQL statement is precompiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times. Note: The setter methods ( setShort, setString , and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter.
Obtaining Auto-generated Keys in Spring JDBC
Therefore, we'll use the JDBCTemplate update() method which supports the retrieval of primary keys generated by the database. This method takes an instance of the PrepareStatementCreator interface as the first argument and the other argument is the KeyHolder. Since the PrepareStatementCreator interface is a FunctionalInterface where its method accepts an instance of java.sql.Connection and ...
Autogenerated Keys
There are three ways of using Autogenerated Keys for insert statements. You can: Pass the flag Statement.RETURN_GENERATED_KEYS to execute or executeUpdate method. Send an array of column names to execute or executeUpdate, so only those column's values are returned by getGeneratedKeys () resultset. Send an array of column indexes to execute or ...
3.6.4 Retrieving AUTO_INCREMENT Column Values through JDBC
Column Values through JDBC. getGeneratedKeys() is the preferred method to use if you need to retrieve AUTO_INCREMENT keys and through JDBC; this is illustrated in the first example below. The second example shows how you can retrieve the same value using a standard SELECT. LAST_INSERT_ID() query. The final example shows how updatable result ...
Using auto-generated keys
Using auto-generated keys. Download JDBC driver. The Microsoft JDBC Driver for SQL Server supports the optional JDBC 3.0 APIs to retrieve automatically generated row identifiers. The main value of this feature is to provide a way to make IDENTITY values available to an application that is updating a database table without a requiring a query ...
getGeneratedKeys with PostgreSQL
Though java.sql.PreparedStatement have getGeneratedKeys, it works pretty different for PostgreSQL than MySQL. The following code block shows the addition of Statement.RETURN_GENERATED_KEYS which is essential for PostgreSQL. String insertSql = "INSERT INTO table1 (c1, c2, c3) VALUES (?, ?, ?)"; PreparedStatement insertPs = conn.prepareStatement ...
Spring Boot GeneratedKeyHolder
GeneratedKeyHolder is a standard implementation of the KeyHolder interface, which is used for holding auto-generated keys. The auto-generated keys are potentially returned by JDBC insert statements. Spring Boot GeneratedKeyHolder example. In the following example we use the GeneratedKeyHolder to retrieve the Id of the created user. In a typical ...
/**Returns the key that was generated from the given statement, or <code>null</code> if no key * was generated or it could not be determined. * * @param stmt the statement that generated a key * @return the key that was generated from the given statement, or <code>null</code> if no key * was generated or it could not be determined. */ private String ...
getGeneratedKeys Method (SQLServerStatement)
Retrieves any auto-generated keys that are created as a result of running this SQLServerStatement object. Syntax public final java.sql.ResultSet getGeneratedKeys() Return Value. A ResultSet object. Exceptions. SQLServerException. Remarks. This getGeneratedKeys method is specified by the getGeneratedKeys method in the java.sql.Statement interface.
Return all generated keys for inserts #245
If multiple values are inserted with Statement.RETURN_GENERATED_KEYS set, driver returns only the last generated key/identity value on calling getGeneratedKeys. But according to JDBC spec, The ResultSet object returned by getGeneratedKeys will contain a row for each value that a statement generated. 👍 15.
Autogenerated keys
This method returns a ResultSet object with a column for the automatically generated key. The Derby implementation of Statement.getGeneratedKeys returns meaningful results only if the last statement was a single-row insert statement. If it was a multi-row insert, Statement.getGeneratedKeys will return a result set with only a single row, even ...

Hello GPT-4o
Prior to GPT-4o, you could use Voice Mode to talk to ChatGPT with latencies of 2.8 seconds (GPT-3.5) and 5.4 seconds (GPT-4) on average. To achieve this, Voice Mode is a pipeline of three separate models: one simple model transcribes audio to text, GPT-3.5 or GPT-4 takes in text and outputs text, and a third simple model converts that text back to audio.
SQLException
48. Your SQLException clearly states that: You need to specify Statement.RETURN_GENERATED_KEYS to the Statement.executeUpdate() or Connection.prepareStatement(). This can be achieved as follows (adding an additional value on Connection.prepareStatement() method): The Statement.RETURN_GENERATED_KEYS is key here. Hope this helps!
