Returning records that partially match a value

Question

I\'m trying to get a query working that takes the values (sometimes just the first part of a string) from a form control. The problem I have is that it only returns records

Answer 1

You have your LIKE expression backwards. I have rewritten the query to remove the unnecessary IIF commands and to fix your order of operands for the LIKE operator:

SELECT TabCustomers.*
FROM TabCustomers
WHERE (Forms!FrmSearchCustomer!SearchMember Is Null Or Forms!FrmSearchCustomer!SearchMember=[customerid]) 
And (Forms!FrmSearchCustomer.SearchFore Is Null Or [customerforname] Like Forms!FrmSearchCustomer!SearchFore & "*") 
And (Forms!FrmSearchCustomer!SearchLast Is Null Or [customersurname] Like Forms!FrmSearchCustomer!SearchLast & "*") 
And (Forms!FrmSearchCustomer!Searchdate Is Null Or [customerDOB] Like Forms!FrmSearchCustomer!Searchdate & "*");

I built that query by replicating the most likely circumstance: I created a dummy table with the fields mentioned and a form with the fields and a subform with the query listed above being refreshed when the search button was pushed. I can provide a download link to the example I created if you would like. The example works as expected. J only picks up both Jim and John, while John or Jo only pulls the John record.
