You cannot meaningfully load an SQL database into a MATLAB session. What you can do is make queries against a database to retrieve the information stored there. For information about that, see https://www.mathworks.com/help/database/import-data.html
... However, it is questionable as to why you bothered to store your license plate related information in an SQL server, unless you have a lot of license plate information. containers.Map() would probably be sufficient for your purposes.

Hello Rya,
Use this to load the database in your workspace:
1. Go to home
2. Click on Import Data
3. Select your file. (I'll suggest to keep data in excel sheet)
4. A window will appear
5. click on import selection and remember the names of variable(Use that variable name in code given below)
Now, use this code to check whether the particular number is present in database or not.
clc;
clear all
X = [1 323 2 44 3 66 77 88 2 1 2 3 34 56 78 5 7 4 44 28]; %Sample DataBase
%Remove above line and replace X by variable name of your database
b = input('enter the number you want to check:');
n = find(X==b);
A = isempty(X(n));
if A==1
disp('The number is not present in database');
else
disp('The number is present in database');
end
