SQL Inner join more than two tables

Question

I can currently query the join of two tables on the equality of a foreign/primary key in the following way.

 $result = mysql_query(\"SELECT * FROM `table1` 
         


        

Answer 1

Try this Here the syntax is

SELECT table1 .columnName, table3 .columnName 
   FROM table1 
     inner join table2 
          ON table1.primarykey = table2.foreignkey 
     inner join table3 
          ON table2.primarykey = table3.foreignkey

for example: Select SalesHeader.invoiceDate,ActualSales,DeptName,tblInvDepartment.DeptCode ,LocationCode from SalesDetail Inner Join SalesHeader on SalesDetail.InvoiceNo = SalesHeader.InvoiceNo inner join tblInvDepartment on tblInvDepartment.DeptCode = SalesDetail.DeptCode
