printout the sql statement built from SQLiteQueryBuilder

To facilita开发者_StackOverflowte debugging, is there any way print out a sql statement before executing following query?

        c = qb.query(
                 epgDB, 
                 projection, 
                 selection, 
                 selectionArgs, 
                 null, 
                 null, 
                 sortOrder); 

If you already used specific SQLiteQueryBuilder methods, e.g. appendWhere(), you can generate the underlying SQL statement simply by calling buildQuery():

SQLiteQueryBuilder qb = new SQLiteQueryBuilder();

// call qb.appendWhere(), qb.appendColumns(), qb.setProjectionMap() etc.

String sql;
sql = qb.buildQuery(null,  null, null, null, null, null, null); // pre API 11
sql = qb.buildQuery(null,  null, null, null, null, null); // API 11 and later

Both methods combine the parameters previously set by individual methods with their own parameters before calling buildQueryString(). They do not change the state of the SQLiteQueryBuilder object and so are safe to use before executing the query.

A word of caution: I learnt this from the code itself, while the javadoc does not mention using this method to get the SQL string. Hence, I advise to be alert of changes that would alter the behavior of the method.
