SELECT i.installid, i.customerid, i.username, iu.internetpassword, i.installdate, i.installmiti, i.billdate, i.billmiti, i.entrydate, i.entrymiti, i.billno, pk.packagesalesid AS freepackagerateid, i.purchasepackageid, si.salesid, i.installcharge, i.total, i.other, i.discount, i.netamount, i.remarks 
FROM tblinstallinfo AS i

JOIN tblsalesinfo AS si ON i.installid = si.installid 
JOIN tblpackagesales AS pk ON i.freepackageid = pk.packagerateid, i.installid = pk.installid 
WHERE pk.remarks = 'free'

推荐答案

这一行：

This line:

JOIN tblpackagesales AS pk ON i.freepackageid = pk.packagerateid, i.installid = pk.installid 

应该是：

Should be:

JOIN tblpackagesales AS pk ON i.freepackageid = pk.packagerateid and i.installid = pk.installid
