getFullConnectString

public String getFullConnectString()

parseStatement

public QueryPart parseStatement(String query)

Description copied from interface: Connection

Parses a statement.

Specified by:

parseStatement in interface Connection

Parameters:

query - MDX string

Returns:

A Query if it is a SELECT statement, a DrillThrough if it is a DRILLTHROUGH statement

createDummyStatement

public Statement createDummyStatement()

parseQuery

public Query parseQuery(String query)

Description copied from interface: Connection

Parses a query.

Specified by:

parseQuery in interface Connection

parseQuery

public Query parseQuery(String query,
                        boolean load)

parseStatement

public QueryPart parseStatement(Statement statement,
                                String query,
                                FunTable funTable,

Parses a query, with specified function table and the mode for strict validation(if true then invalid members are not ignored).

This method is only used in testing and by clients that need to support customized parser behavior. That is why this method is not part of the Connection interface.

See test case mondrian.olap.CustomizedParserTest.

Parameters:

statement - Evaluation context

query - MDX query that requires special parsing

funTable - Customized function table to use in parsing

strictValidation - If true, do not ignore invalid members

Returns:

Query the corresponding Query object if parsing is successful

Throws:

MondrianException - if parsing fails

parseExpression

public Exp parseExpression(String expr)

Description copied from interface: Connection

Parses an expresion.

Specified by:
