Method Detail

createQuery

public static QueryRootNode createQuery(String statement,
                                        NameResolver resolver,
                                        QueryNodeFactory factory)
                                 throws InvalidQueryException

Creates a QueryNode tree from a SQL statement using the passed query node factory.

Parameters:

statement - the SQL statement.

resolver - the namespace resolver to use.

Returns:

the QueryNode tree.

Throws:

InvalidQueryException - if statement is malformed.

toString

public static String toString(QueryRootNode root,
                              NameResolver resolver)
                       throws InvalidQueryException

Creates a String representation of the query node tree in SQL syntax.

Parameters:

root - the root of the query node tree.

resolver - to resolve QNames.

Returns:

a String representation of the query node tree.

Throws:

InvalidQueryException - if the query node tree cannot be converted into a String representation due to restrictions in SQL.
