命令包含无法识别的短语/关键字 VFP with SQL

Question

我在使用 visual fox pro SQL 命令时遇到问题，它不断给我诸如“INNER JOIN 不存在”之类的错误（当我放置内部联接时，如果没有它，当我执行选择

*!* SELECT * FROM ALTBREQU
*!* *--emp_ccodigo,req_cnumero,cen_ccodigo(codigo de centro de costo)
*!* SELECT * FROM ALTBDREQ
*!* *--emp_ccodigo, req_cnumero,pro_ccodigo,dre_ncantid,dre_ncosref
*!* SELECT * FROM ALTBPROD
*!* *--emp_ccodigo, pro_ccodigo, pro_cdescor
*!* SELECT * FROM COTBASOC
*!* *--emp_ccodigo,aso_ccodigo(unidad operativa),aso_cnombre
*!* SELECT * FROM CGTBCENT
*!* *--emp_ccodigo,cen_ccodigo,cen_cdescri

OPEN DATABASE dbalmacen
OPEN DATABASE dbcompras
OPEN DATABASE dbcontab

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

非常感谢您。

取出JOIN 语句中的ANDs - 这应该可以让您使用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
