Hello,

Here is my problem, i try to do a query with two tables, MKTG_USER and MKTG_REQUERIMIENTOS.

my inner join is

MKTG_USER ON MKTG_REQUERIMIENTOS.ID_USER = MKTG_USER.ID_USUARIO AND MKTG_REQUERIMIENTOS.ID_CLIENTE = MKTG_USER.ID_USUARIO

and that dont get any data, in MKTG_USER.ID_USUARIO is PK,
MKTG_REQUERIMIENTOS.ID_USER is FK and MKTG_REQUERIMIENTOS.ID_CLIENTE is FK

the RS of Tables is here

The only way this will return anything is if MKTG_REQUERIMIENTOS.ID_USER = MKTG_REQUERIMIENTOS.ID_CLIENTE
If MKTG_USER is to be used for two different reasons then it would need to be linked twice

SELECT T2.NOM_USUARIO Vendedor, T3.NOM_USUARIO Cliente FROM MKTG_REQUERIMIENTOS T1
INNER JOIN MKTG_USER T2 ON T2.ID_USUARIO = T1.ID_USER
INNER JOIN MKTG_USER T3 ON T3.ID_USUARIO = T1.ID_CLIENTE

Here is the query result
