get the columne name of a table in matlab

To get the column names of a table in MATLAB, you can use the fetch function with the 'FieldName' option set to true. Here is an example:

main.m
% First, connect to a database
conn = database('mydatabase', 'username', 'password');

% Next, fetch the data from the table and specify that you want the field names
results = fetch(conn, 'SELECT * FROM mytable WHERE 1=0', 'FieldName', true);

% Finally, extract the field names from the results structure
column_names = fieldnames(results);

% Display the column names
disp(column_names)
390 chars
12 lines

In this example, we first connect to a database using the database function, specifying the database name, username, and password. Then, we use the fetch function to retrieve an empty result set from the table mytable, with the 'FieldName' option set to true. This causes the output structure results to contain the field names as its top-level field names. Finally, we extract these field names using the fieldnames function and display them using disp.
