<span style="color:blue; font-family:Consolas; font-size:9.5pt I have a SQL Express database that I use quite successfully to track my investments in several accounts.<span style="
I built it myself, itâs quite functional, and Iâm happy with it.<span style="
The problem is that there are multiple account tables and updating them can be tedious in SQL Server, if multiple purchases and sales in multiple accounts have occurred in a month.<span style="
Tedium can lead to errorsâ

<span style="color:blue; font-family:Consolas; font-size:9.5pt My skill level in VB is somewhere between nil and very little.<span style="
My skill level in SQL is modest, but I can get by.<span style="
I also have access to help in the SQL department.<span style=" So, the SQL end of things is actually OK.<span style="
I may have issues with SQL Server as its set up on my computer, however.<span style="
