Yes it can be done. &nbsp;They are called Triggers.<br />
<br />
Under They are called triggers and are specific to the Table. &nbsp;You can setup updates to respond to Updates Deletes and Updates (Updates are a combination of Inserts and Deletes). &nbsp;The syntax takes some getting used to but is slick when its done right as everything is managed by the SQL server issue, Multi-User issues cease to be issues and more.<br />
<br />
Take care to be aware of the fact that some triggers can fire other triggers and you don't want your triggers to loop back on themselves (that will cause problems). &nbsp;Even, careful and limited use of this feature can be very useful and powerful.<br />

<div>
create trigger tr_yourtriggername<br />
on file1<br />
for update<br />
as<br />
begin<br />
update f2<br />
date2 = i.date1, date3 = i.date1<br />
from file2 f2 join inserted i on f2.commonfield = i.commonfield<br />
<br />
end
</div>


<div>
I greatly appreciate both reponses. Feeling fairly green can you explain the<br />
f2<br />
i.date1 &nbsp;(specifically what the i is - )<br />
file2 f2 join inserted i (specifically the f2) <br />
<br />

</div>


<div>
To write the trigger we'd need to know...<br />
<br />
1) When you want the trigger fire.<br />
2) What you want it to do want it to do when it does.<br />
<br />
Include Table and field names involved including Sum and aggregates calculations, Primary Keys' and the like.
</div>


<div>
I have 2 files.<br />
FILE1 &nbsp;- &nbsp;Oeordfil_sql with fields ord_no, ship_date &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
FILE2 - Oeordlin.sql with fields ord_no, req_date, promise_date<br />
When the oeordfil_sql ship_date field is updated by the user <br />
I need the oeordlin_sql req_date &nbsp;and promise date to be updated <br />
With the oeordhdr_sql ship_date.<br />
<br />
Both files have the ord_no to match on<br />

</div>


<div>
Tabe: Oeordfil<br />
&nbsp; Field: ord_no<br />
&nbsp; Field: ship_date &nbsp; &nbsp; &nbsp;<br />
<br />
Table: Oeordinl <br />
&nbsp; Field: ord_no<br />
&nbsp; Field: req_date<br />
&nbsp; Field: promise_dat<br />
<br />
What is... oeordhdr_sql.ship_date &nbsp; &nbsp; ...a 3rd table &amp;&nbsp;field?<br />

</div>


<div>
no &nbsp;it was a mistype &nbsp;the date wold come from the oeordfil file field ship_date and update the 2 fields in the second table
</div>


<div>
The solution was pefect and worked well. I did have to insert the word set after the update command, other then that it works flawlessly - thanks for all the help.<br />
<br />
<br />
create trigger tr_yourtriggername<br />
on Oeordfil<br />
for update<br />
as<br />
begin<br />
update f2 SET date2 = i.ship_date, <br />
date3 = i.ship_date<br />
from Oeordinl f2 join inserted i on f2.ord_no= i.ord_no <br />
end<br />

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Microsoft SQL Server

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
