Note that it is important to set the 'mode' to 'csv' before. import ' command takes two arguments which are the name of the disk file from which CSV data is to be read and the name of the SQLite table into which the CSV data is to be inserted. import -csv C:/csv/source_file_crlf.csv myTable import ' command to import CSV (comma separated value) data into an SQLite table. Use ".open FILENAME" to reopen on a persistent database. The last record in the file may or may not have an ending lineĪfter i replaced the line separators \n with a line break (using SHIFT ENTER in vs code) the import under windows was possible using c:\Apps\SQLite\sqlite_3.40.1>sqlite3.exeĬonnected to a transient in-memory database. Alias, Name, Agency\nįrom Common Format and MIME Type for Comma-Separated Values (CSV) FilesĮach record is located on a separate line, delimited by a line separator ' ooga booga 'Īs for the rest, SQLite is telling you the problem: the separator isn't matching somehow.In my case i had a similar problem the lines in the csv file did contain a \n instead of an actual a CRLF (line break). import /tmp/deleteme.csv users' I don't get errors but I also don't end up with any data in the users table. lab-1:/etc/scripts sqlite3 test.db '.mode csv. separator also affects SQLite's output, not just its. lab-1:/etc/scripts sqlite3 test.db '.mode csv. mode selection, telling it to use semicolons as separators, and that the difference is due to restarting sqlite3, causing the separator and other modes to be reset to their defaults. I expect this is just a reflection of your earlier. Once again, one thing is happening on your local computer, but you then go to show us something different. and then you go on to show semicolons and double-quotes instead. Several other programs expecting CSV/TSV style input also want that header. Unless you depend on the column affinities being set up in a certain way, it's simpler to just add a header row to the input file. You can pre-define the schema, as you discovered, to get around this. To export an SQLite table (or part of a table) as CSV, simply set the 'mode' to 'csv' and then run a query to extract the desired rows of the table. It means the first row of your CSV file isn't a header, listing the names of the columns. I assume this isn't a literal copy-and-paste from a SQLite command session, else later parts of your explanation wouldn't be working, which then leads me to ask, why are you posting commands here that differ from what you're actually typing? Why make us second-guess your description in order to make any sense of it? Why are you putting a space between the "c:" bit and the rest of the path? That's two paths, the first meaning "the current working directory on the C drive". This article used CSV files to import data records to the SQLite database table using the import instruction at the shell. import c: /users/inspiron/desktop/people2012.csv Sqlite> select * from people2012 limit 10 To go from SCRATCH with SQLite DB to importing the CSV into a table: Get SQLite from the website. However, when specifying the base, there is no value in the columns. So, as the procedure didn't work, I tried to create the table first (with the columns separated by a comma):Ĭ: /users/inspiron/desktop/pessoas2012.csv:11: expected 120 columns but found 1 - filling the rest with NULL In new versions of SQLite, all the above commands can be executed in one go. Column names present in the first row of the CSV file will be used as column names for the created table. import c: /users/inspiron/desktop/people2012.csv people2012ĬREATE TABLE people2012 (.) failed: duplicate column name: import data.csv mytable command imports all the data in the data.csv file to a new table, mytable. I am using the following command to import this database: I have a base with 81,372,577 observations and whose columns are separated by semicolons.
