Class NamedParameterJdbcTemplate

java.lang.Object

org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate

All Implemented Interfaces:

NamedParameterJdbcOperations

public class NamedParameterJdbcTemplate
extends Object
implements NamedParameterJdbcOperations

Template class with a basic set of JDBC operations, allowing the use of named parameters rather than traditional '?' placeholders.

This class delegates to a wrapped JdbcTemplate once the substitution from named parameters to JDBC style '?' placeholders is done at execution time. It also allows for expanding a List of values to the appropriate number of placeholders.

The underlying JdbcTemplate is exposed to allow for convenient access to the traditional JdbcTemplate methods.

NOTE: An instance of this class is thread-safe once configured.

Since:

2.0

The callback action can return a result object, for example a domain object or a collection of domain objects.

Specified by:

execute in interface NamedParameterJdbcOperations

Parameters:

sql - the SQL to execute

paramSource - container of arguments to bind to the query

action - callback object that specifies the action

Returns:

a result object returned by the action, or null

Throws:

DataAccessException - if there is any problem

Description copied from interface: NamedParameterJdbcOperations

Query given SQL to create a prepared statement from SQL and a list of arguments to bind to the query, expecting an SqlRowSet.

The results will be mapped to an SqlRowSet which holds the data in a disconnected fashion. This wrapper will translate any SQLExceptions thrown.

Note that, for the default implementation, JDBC RowSet support needs to be available at runtime: by default, Sun's com.sun.rowset.CachedRowSetImpl class is used, which is part of JDK 1.5+ and also available separately as part of Sun's JDBC RowSet Implementations download (rowset.jar).

Specified by:

queryForRowSet in interface NamedParameterJdbcOperations

Parameters:

sql - the SQL query to execute

paramSource - container of arguments to bind to the query

Returns:

an SqlRowSet representation (possibly a wrapper around a javax.sql.rowset.CachedRowSet)

Throws:

DataAccessException - if there is any problem executing the query

getPreparedStatementCreator

protected PreparedStatementCreator getPreparedStatementCreator(String sql,
 SqlParameterSource paramSource)

Build a PreparedStatementCreator based on the given SQL and named parameters.

Note: Directly called from all query variants. Delegates to the common getPreparedStatementCreator(String, SqlParameterSource, Consumer) method.

Parameters:

sql - the SQL statement to execute

paramSource - container of arguments to bind

Returns:

the corresponding PreparedStatementCreator

See Also:

• getPreparedStatementCreator(String, SqlParameterSource, Consumer)

getPreparedStatementCreator

protected PreparedStatementCreator getPreparedStatementCreator(String sql,
 SqlParameterSource paramSource,
 @Nullable
 Consumer<PreparedStatementCreatorFactory> customizer)

Build a PreparedStatementCreator based on the given SQL and named parameters.

Parameters:

sql - the SQL statement to execute

paramSource - container of arguments to bind

customizer - callback for setting further properties on the PreparedStatementCreatorFactory in use), applied before the actual newPreparedStatementCreator call

Returns:
