Matlab script :

conn=database('dcr','ODBC','') % Connect to database

Curs=exec(conn,’SELECT ALL start_time FROM sngl_burst WHERE ifo= …‘SEI _NBC_SEIS-X’ ORDER BY snr ASC; % execute SQL command

curs=fetch(curs,5);

Close(conn)___________________________________________________________

>>curs.Data = [6943333500] [6943556721]

[6945123456] [6946123456] [6948213456]
