thisform.grid1.recordsource="sele * from 外汇账户 where 钞汇标志 ='"+iif(thisform.myoption.value=1,"现汇","现钞")"'into cursor 1sb"

解释下这句VFP thisform.grid1.recordsource="sele * from 外汇账户 where 钞汇标志 ='"+iif(thisform.myoption.value=1,"现汇","现钞")"'into cursor 1sb"
sele * from 外汇账户="从外汇账户上选择 * "
'*'号为外汇账户中的某一个(些)账户
而取得'*'号的条件为 :where 钞汇标志 ='"+iif(thisform.myoption.value=1,"现汇","现钞")"
把符合以上条件的账户放入到 cursor 1 sb
