Class JdbcPreparedStatement

java.lang.Object

org.h2.message.TraceObject

org.h2.jdbc.JdbcStatement

org.h2.jdbc.JdbcPreparedStatement

All Implemented Interfaces:

java.lang.AutoCloseable, java.sql.PreparedStatement, java.sql.Statement, java.sql.Wrapper, JdbcStatementBackwardsCompat

Direct Known Subclasses:

JdbcCallableStatement

public class JdbcPreparedStatement
extends JdbcStatement
implements java.sql.PreparedStatement

Represents a prepared statement.

Thread safety: the prepared statement is not thread-safe. If the same prepared statement is used by multiple threads access to it must be synchronized. The single synchronized block must include assignment of parameters, execution of the command and all operations with its result.

 synchronized (prep) {
     prep.setInt(1, 10);
     try (ResultSet rs = prep.executeQuery()) {
         while (rs.next) {
             // Do something
         }
     }
 }
 synchronized (prep) {
     prep.setInt(1, 15);
     updateCount = prep.executeUpdate();
 }

If SQL command inserts or updates multiple rows with generated keys each such inserted or updated row is returned. Batch methods are also supported.

When Statement.RETURN_GENERATED_KEYS is used H2 chooses columns to return automatically. The following columns are chosen:

• Columns with sequences including IDENTITY columns and columns with AUTO_INCREMENT.
• Columns with other default values that are not evaluated into constant expressions (like DEFAULT RANDOM_UUID()).
• Columns that are included into the PRIMARY KEY constraint.

Exact required columns for the returning result set may be specified on execution of command with names or indexes of columns.
