Don't ask why I needed this, but here is a SQL function that will abbreviate a string:
{style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; margin: 0em; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, 'Courier New', courier, monospace; border-right-style: none; border-left-style: none; background-color: white; border-bottom-style: none"}
create function dbo.fnAbbreviate(@source nvarchar(100))
{style="padding-right: 0px; padding-left: 0px; font-size: 8pt; padding-bottom: 0px; margin: 0em; overflow: visible; width: 100%; color: black; border-top-style: none; line-height: 12pt; padding-top: 0px; font-family: consolas, 'Courier New', courier, monospace; border-right-style: none; border-left-style: none; background-color: #f4f4f4; border-bottom-style: none"}
returns nvarchar(100)
