Data Export with an SQL Query
The following query exports data into a file formatted in comma-separated values (CSV):
SELECT From_User_Name, Text INTO "csv://Tweets.txt" FROM "Tweets" WHERE From_User_Name = 'twitter'
You can specify other formats in the file URI. The possible delimiters are tab, semicolon, and comma with the default being comma. The following example exports tab-separated values:
SELECT From_User_Name, Text INTO "csv://Tweets.txt;delimiter=tab" FROM "Tweets" WHERE From_User_Name = 'twitter'
