You can also use the setX methods where X is the type of the parameter. But at the end of the day I think you have to ask why you are having to tie yourself in knots this way. Hibernate is supposed to do this for you. What's wrong with mapping the name and id and using Hibernate to generate the inserts / updates? You can resolve this problem, if you are using batch processing with Hibernate. To use the batch processing feature, first set hibernate.jdbc.batch_size as batch size to a number either at 20 or 50 depending on object size. This will tell the hibernate container that every X rows to be inserted as batch.

This is the central class in the JDBC core package. It simplifies the use of JDBC and helps to avoid common errors. It executes core JDBC workflow, leaving application code to provide SQL and extract results. This class executes SQL queries or updates, initiating iteration over ResultSets and catching JDBC exceptions and translating them to the generic, more informative exception hierarchy defined in the org.springframework.dao package.

Code using this class need only implement callback interfaces, giving them a clearly defined contract. The callback interface creates a prepared statement given a Connection, providing SQL and any necessary parameters. The interface extracts values from a ResultSet. See also and for two popular alternative callback interfaces. Can be used within a service implementation via direct instantiation with a DataSource reference, or get prepared in an application context and given to services as bean reference. Note: The DataSource should always be configured as a bean in the application context, in the first case given to the service directly, in the second case to the prepared template.

Because this class is parameterizable by the callback interfaces and the interface, there should be no need to subclass it. All SQL operations performed by this class are logged at debug level, using 'org.springframework.jdbc.core.JdbcTemplate' as log category. NOTE: An instance of this class is thread-safe once configured.

Since: May 3, 2001 Author: Rod Johnson, Juergen Hoeller, Thomas Risberg See Also:,,,,,,. Set the fetch size for this JdbcTemplate. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.

Default is -1, indicating to use the JDBC driver's default configuration (i.e. To not pass a specific fetch size setting on to the driver). Note: As of 4.3, negative values other than -1 will get passed on to the driver, since e.g. MySQL supports special behavior for Integer.MIN_VALUE. See Also: Statement.setFetchSize(int) • getFetchSize public int getFetchSize(). Set the maximum number of rows for this JdbcTemplate.

This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the JDBC driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches). Default is -1, indicating to use the JDBC driver's default configuration (i.e.

To not pass a specific max rows setting on to the driver). Note: As of 4.3, negative values other than -1 will get passed on to the driver, in sync with 's support for special MySQL values. See Also: Statement.setMaxRows(int) • getMaxRows public int getMaxRows(). Execute a JDBC data access operation, implemented as callback action working on a JDBC Connection. This allows for implementing arbitrary data access operations, within Spring's managed JDBC environment: that is, participating in Spring-managed transactions and converting JDBC SQLExceptions into Spring's DataAccessException hierarchy. The callback action can return a result object, for example a domain object or a collection of domain objects.

Specified by: in interface Parameters: action - the callback object that specifies the action Returns: a result object returned by the action, or null Throws: - if there is any problem • createConnectionProxy protected java.sql.Connection createConnectionProxy(java.sql.Connection con). Execute a JDBC data access operation, implemented as callback action working on a JDBC Statement.
