Question

Delphi 2010 & Oracle Database

I need to write a select statement across two tables

Accounts & Master

From the Accounts table, I need to select the Account_Id, Account_Number, Bank_Id, and External_Code

From the Master table, i need to select the Account_String.

The Master’s Account_String field matches the Account’s Extenal_Code field

Answer 1

Sounds like a simple join, unless I’m missing something:

SELECT a.Account_Id, a.Account_Number, a.Bank_Id, a.External_Code, m.Account_String 
FROM Accounts a
INNER JOIN Master m ON m.Account_String = a.External_Code
