QueryMapper

public QueryMapper(QueryProcessorIF processor,
                   DeclarationContextIF context)

Method Detail

isTrue

public boolean isTrue(String query)

EXPERIMENTAL: Returns true if the query produces a row and false if the query produces no rows.

isTrue

public boolean isTrue(String query,
                      Map<String,?> params)

EXPERIMENTAL: Returns true if the query produces a row and false if the query produces no rows.

queryForObject

public T queryForObject(String query)

EXPERIMENTAL: Returns the value in the first column in the first row of the query result. If the query produces no results null is returned.

queryForObject

public T queryForObject(String query,
                        Map<String,?> params)

EXPERIMENTAL: Returns the value in the first column in the first row of the query result. If the query produces no results null is returned.

queryForObject

public T queryForObject(String query,
                        RowMapperIF<T> mapper)

EXPERIMENTAL: Returns the value in the first column in the first row of the query result. If the query produces no results null is returned.

queryForObject

public T queryForObject(String query,
                        RowMapperIF<T> mapper,
                        Map<String,?> params)

EXPERIMENTAL: Returns the mapping of the value in the first column in the first row of the query result. If the query produces no results null is returned.

queryForList

public List<T> queryForList(String query)

EXPERIMENTAL: Runs the query, and returns a the single value in each row.

queryForList

public List<T> queryForList(String query,
                            RowMapperIF<T> mapper)

EXPERIMENTAL: Runs the query, and calls the mapper for each row in the query result. Returns a list of all the objects produced by the mapper in query result order.

queryForList

public List<T> queryForList(String query,
                            Map<String,?> params)

EXPERIMENTAL: Runs the query, and returns a the single value in each row.

queryForList

public List<T> queryForList(String query,
                            RowMapperIF<T> mapper,
                            Map<String,?> params)

EXPERIMENTAL: Runs the query with the given parameters, and calls the mapper for each row in the query result. Returns a list of all the objects produced by the mapper in query result order.

queryForMap

public Map<String,T> queryForMap(String query)

EXPERIMENTAL: Returns a map of the first row of the query results, with each variable name (without $) as a key and each variable value as the value of the key. If the query produces no rows the method returns null; if it produces more than one an exception is thrown.

queryForMap

public Map<String,T> queryForMap(String query,
                                       Map<String,?> params)

EXPERIMENTAL: Returns a map of the first row of the query results, with each variable name (without $) as a key and each variable value as the value of the key. If the query produces no rows the method returns null.

wrapValue

protected T wrapValue(Object value)

execute

protected QueryResultIF execute(String query,
                                Map<String,?> params)
                         throws InvalidQueryException
