Method Detail

getJdbcOperations

JdbcOperations getJdbcOperations()
Expose the classic Spring JdbcTemplate to allow invocation of less commonly used methods.


queryForInt

int queryForInt(String sql,
                Object... args)
                throws DataAccessException
Query for an int passing in a SQL query and a variable number of arguments.

Throws:
DataAccessException

queryForLong

long queryForLong(String sql,
                  Object... args)
                  throws DataAccessException
Query for an long passing in a SQL query and a variable number of arguments.

Throws:
DataAccessException

queryForObject

<T> T queryForObject(String sql,
                     Class<T> requiredType,
                     Object... args)
                 throws DataAccessException
Query for an object of type T identified by the supplied @Class.

Parameters:
sql - the SQL query to run.
requiredType - the required type of the return value.
args - the args for the query.
Throws:
DataAccessException
See Also:
JdbcOperations.queryForObject(String, Class), JdbcOperations.queryForObject(String, Object[], Class)

queryForObject

<T> T queryForObject(String sql,
                     ParameterizedRowMapper<T> rm,
                     Object... args)
                 throws DataAccessException
Query for an object of type T using the supplied ParameterizedRowMapper to the query results to the object.

Parameters:
sql - the SQL query to run.
rm - the @ParameterizedRowMapper to use for result mapping
args - the args for the query.
Throws:
DataAccessException
See Also:
JdbcOperations.queryForObject(String, org.springframework.jdbc.core.RowMapper), JdbcOperations.queryForObject(String, Object[], org.springframework.jdbc.core.RowMapper)

query

<T> List<T> query(String sql,
                  ParameterizedRowMapper<T> rm,
                  Object... args)
              throws DataAccessException
Query for a List of Objects of type T using the supplied ParameterizedRowMapper to the query results to the object.

Parameters:
sql - the SQL query to run.
rm - the @ParameterizedRowMapper to use for result mapping
args - the args for the query.
Throws:
DataAccessException
See Also:
JdbcOperations.queryForObject(String, org.springframework.jdbc.core.RowMapper), JdbcOperations.queryForObject(String, Object[], org.springframework.jdbc.core.RowMapper)

queryForMap

Map<String,Object> queryForMap(String sql,
                               Object... args)
                               throws DataAccessException
Execute the supplied query with the (optional) supplied arguments.

The query is expected to be a single row query; the result row will be mapped to a Map (one entry for each column, using the column name as the key).

Throws:
DataAccessException
See Also:
JdbcOperations.queryForMap(String), JdbcOperations.queryForMap(String, Object[])

queryForList

List<Map<String,Object>> queryForList(String sql,
                                      Object... args)
                                      throws DataAccessException
Execute the supplied query with the (optional) supplied arguments.

Each element in the returned List is constructed as a Map as described in queryForMap(java.lang.String, java.lang.Object...)

Throws:
DataAccessException
See Also:
JdbcOperations.queryForList(String), JdbcOperations.queryForList(String, Object[])

update

int update(String sql,
           Object... args)
