I need to examine the bigdata file with a database/DBMS and have used MS Office 365/Access successfully so to do, import and query. I have also tried, many times, to open a MMA 10.4 database link connection to examine the CSV file (and also the .accdb file resulting from success with Access) under Windows 7.
I never had any success using MMA and choosing either SQLite or HSQL engines. OpenSQLConnection gets me into and out of a multistep dialog OK. I seem to have achieved a connection, but it's never one that ever satisfies MMA. For example, SQLTableNames and SQLTableInformation (to list column headings) always fail to produce any correct answers.
Do I need to import then export the .CSV file in a format the MMA is happier with during the multi-step dialog? Some file format other than .csv or other than .accdb? Do I need to specify some properties or identify a "catalog" during the OpenSQLConnection dialog? TIA for a reply, Lew R
Per Bill, I scraped the header row and first five data rows of the database. See attached screen shot:
Since the way to upload 'live' small .csv and .xlsl files is not obvious to me (maybe any file uploading is not welcome on this site), I will instead ponder how best to provide them. Maybe uploading the files to my website is the best answer.
Edit: Here's the mini CSV example as plain text:
Site_Name,Parameter,DateTime_LST,Value,Unit Shangra-LA,AmbT,1/1/1990 0:00,4.7,degC Shangra-LA,AmbT,1/1/1990 1:00,4.8,degC Shangra-LA,AmbT,1/1/1990 2:00,4.9,degC Shangra-LA,AmbT,1/1/1990 3:00,4,degC Shangra-LA,AmbT,1/1/1990 4:00,3.3,degC
