To get the BIGINT data as INT64 into MATLAB you can retrieve the number as string and then use the attached MEX-file below to convert to INT64.
To retrieve the data as text you could consider changing the actual data format in your database or you could simply include a CAST in your query:
>> setdbprefs('DataReturnFormat','cellarray');
>> conn = database('myDatabase','myUser','myPassword');
>> res = exec(conn,'SELECT CAST(col1 AS VARCHAR) FROM myTable');
>> res = fetch(res);
>> data = res.data;
>> longlong = atoi64(data(:,1))
longlong =
12345678901234567
98765432104567895
Compile it using:
>> mex atoi64.c
Before using it.
