Customer Question

HiI have 10 tables that have all the same fields in. These are :LeadID|customernumber|salevalue|MarketingcodeEach table is named: custom_1 up to custom_10I then have a master_table that has the below fields in:LeadID|Eventdate|Status|ListIDThe leadID is the key that will link the custom_ tables to the master table.The listID in the master table is the number of the custom table (i.e customer_2 etc )I am just learning PHP and cannot work out how to take the leadid and pull back all data linked to that leadid in all of the custom tables to then perform the calculations I need.I want to end up with an output that gives me by date or date range:Date| Marketingcode| Count of sales | sum of salevalueI could just do a union all on the custom tables but my understanding is in php that’s isn’t needed as you can create a query that will loop through all the different tables instead.Would be extremely grateful for any help you can give.

May I know if you are trying to build an SQL Query?

Expert:  Su-ada M replied 1 year ago.

You can use 1 custom table and incorporate all customer details rather than 10.and If you need that can refer to a customer master also. Database normalization suggests to minimize the redundancy.

In that case, simple join in SQL query would do the job.
