可能的原因是在最后一列的语句中，多了一个逗号，应该将其删除。正确的语句应该为：

create view table_dgd0622 as select ROW_NUMBER() OVER (ORDER BY a.id) AS dgd_id, a.*, b.id as mxid, b.mainid, b.wlbh, b.pm, b.ggcz, b.dw, b.sl, b.dj, b.sl1, b.je, b.bz, b.dj2, b.dw1, b.qgdh, b.bjjg, b.prdh, b.cgjsqgdsj, b.prbhfz from formtable_main_43 a LEFT join formtable_main_43_dt1 b on a.Id=b.mainid
