You're looking for the "left outer join" symbol "⟕". The question has already been asked before: Symbols for Outer Joins –  diabonas Sep 18 '11 at 10:40

To use unicode characters in LaTeX, you can load \usepackage[utf8]{inputenc} in your preamble. Then you can either just type the symbol if it's on your keyboard, or you can hold Alt and enter the unicode number on your number pad if you use Windows, or press Shift+Ctrl+u and then enter the unicode number if you're using Ubuntu.

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{document}
\end{document}


This will only work if the font you're using supports the character, which most likely isn't the case for Unicode 10197 (my system can't display it, and compilation with this character fails for me).

You might be looking for a different symbol: Using Detexify to look up your symbol yields $\forall$, which looks like this

which is similar, but not identical, to Unicode 10197, which, according to fileformat.info looks like this:

But... The character I want to input is &#10197; I found here.coolshell.cn/wp-content/uploads/2009/08/Unicode-table.htm Is your character in hex? –  Times N. Roman Sep 18 '11 at 8:02
@Times: Sorry, yeah, I assumed the symbol to be in hex. The problem with the character missing from the font is the same with this symbol, though. Maybe you should post a new question, "How can I insert a Left Outer Join Symbol in LaTeX". –  Jake Sep 18 '11 at 8:12
Is there a tool like Detexify that recognizes unicode? –  Times N. Roman Sep 18 '11 at 8:32
