CREATE SQL VIEW prueba AS ;
SELECT * FROM ALTBREQU;
 JOIN ALTBDREQ ON ALTBREQU.req_cnumero = ALTBDREQ.req_cnumero AND;
JOIN ALTBPROD ON ALTBDREQ.pro_ccodigo = ALTBPROD.pro_ccodigo AND;
JOIN CGTBCENT ON ALTBREQU.cen_ccodigo = CGTBCENT.cen_ccodigo

在AND语句中取出JOIN，这应该使您可以使用INNER:

CREATE SQL VIEW prueba AS ;
SELECT * FROM ALTBREQU;
INNER JOIN ALTBDREQ ON ALTBREQU.req_cnumero = ALTBDREQ.req_cnumero ;
INNER JOIN ALTBPROD ON ALTBDREQ.pro_ccodigo = ALTBPROD.pro_ccodigo ;
INNER JOIN CGTBCENT ON ALTBREQU.cen_ccodigo = CGTBCENT.cen_ccodigo
