Hello Joep,
As per my understanding, you want to get the maximum length of a cell when importing SQLdatabase.
Please know that in this case, you can use the “options.MaxVarCharLength” which is a property that can be set when using the “fetch” or “sqlread” functions to specify the maximum length of character data that should be retrieved from a SQL-based database.
In some cases, the default behavior of these functions is to limit the length of fetched data to a certain number of characters, which can result in truncation of longer strings or arrays. By setting “options.MaxVarCharLength” to a higher value, you can increase the maximum length of the fetched data.
To set the maximum length for importing data from a Databricks SQL-based database, you can modify the “fetch” or “sqlread” functions to specify the desired maximum length. By default, these functions may limit the length of fetched data to a certain number of characters, such as 255 characters.
Here's a sample code to demonstrate how you can modify your code to set a higher maximum length:
conn = odbc('DSN=Database');
vars = [];
query = 'SELECT * FROM anonymizedDatabase';
tablename = 'anonymizedDatabase.table';
% Set the maximum length for data retrieval
options = fetchOptions();
options.MaxVarCharLength = 10000; % Set a high value for maximum length
%% Execute query and fetch results
data = fetch(conn, query, options);
%% Alternative
data = sqlread(conn, tablename, 'MaxRows', 100, 'MaxVarCharLength', 10000);
%% Close connection to the database
close(conn)
In the above code, “options.MaxVarCharLength” is set to a higher value i.e. 10000 to allow for longer data to be fetched. You can adjust this value as per your requirements.
I hope this helps!
