Try:
Select flbss, max(flbtdt), flbhst
From flbhrep
Where flbhst in ('470','471','476','478')
And flbtdt >= '2008-02-01'
Group by flbss, flbhst
Order by flbss
For each account number and history code combination, select the one
with the most recent date.

Subject: My SQL Question
Fellow Midrangers,
I am attempting to find the most recent occurrance by date of one of
four history codes. I will use only the first one I get to update
another file. I have tried SELECT DISTINCT and Fetch First Row Only but
I get a 26501 SQLSTT error. I removed those and instead am reading all
records which qualify and handling the file update in another manner
(only updating those which have not been previously updated). This is a
one time program so strict efficiency is not required.
When I run this through debug, instead of getting one of my four codes,
I am getting blank codes. Where am I going wrong here? When I run it
interactively, I get records with codes.
// Get `470`, `471`, `476` And `478` Account Records From History;
// Assemble Select Statement
QQS = 'Select FLBSS, FLBTDT Desc, FLBHST From FLBHREP ';
// Set Where For Selected History Codes Since 02/01/2008
QQW = 'Where FLBHST In (?, ?, ?, ?) And FLBTDT >= ? '; // Codes Since
2/1/2008
// Set Order By Sort Method
QQO = 'Order By FLBSS '; // Order By Account
// Move SQL Statements To A Single Field
QQSQL = %Trim(QQS) + ' ' + %Trim(QQW) + ' ' + %Trim(QQO) + For_Read;
// Move Statements
// Declare, Then Open Cursor
Exec SQL Prepare SQL_Stmt2 From :QQSQL; // Prepare Executable
Statement
Exec SQL Declare @C2 Cursor For SQL_Stmt2; // Declare Cursor
Exec SQL Open @C2 // Open Cursor...
Using :History_Code_470, :History_Code_471,
:History_Code_476, :History_Code_478,
:Base_Date_7; // Using These Values
Any help appreciated. I must finish this by EOD. I don't want to
create a logical for this. SQL should do it.
