CreateCriteria, joining associations

How can I write the following SQL using CreateCriteria:

SELECT  sa_bec_matricula.*
FROM    sa_bec_matricula
        INNER JOIN sa_matricula ON sa_bec_matricula.sa_mtc_num = sa_matricula.sa_mtc_num
        INNER JOIN sa_periodo ON sa_matricula.sa_per_cod = sa_periodo.sa_per_cod
        INNER JOIN sa_tpo_beca ON sa_bec_matricula.sa_tpo_bec_cod = sa_tpo_beca.sa_tpo_bec_cod
WHERE   sa_periodo.sa_per_abi = 1
        AND sa_t开发者_运维百科po_beca.sa_tpo_bec_gpr = 2

It depends on your models and how they are mapped to your tables as Criteria are in terms of properties on objects not tables in schemas.
