Just agree with the prompts until it’s saved in the user’s home directory. This is a hidden file, so you might get various prompts asking you to confirm, etc depending on your system. sqliterc to the user’s home directory, and SQLite will use it each time it connects.įor example, if the user’s home directory is /Users/bart, then you would place it inside that directory, so that it’s located at /Users/bart/.sqliterc. sqliterc file.įor example, open a blank text file and enter the following. To save yourself from having to re-enter the above commands every time you connect to SQLite, you can enter them into a. Persist the Column SettingsĪs mentioned, every time you open a new terminal window to connect to SQLite, queries will revert to SQLite’s default format (pipe-separated list). separator ", " to output the results as a comma separated list. In case you’re wondering, yes, you can use. separator dot command, just in case you’d previously changed the separator. '.header on' command You may have noticed the we have use '.header on' and '.mode column' commands before the SELECT Statement '.header on' command is used to display the output table header '.mode column' command '. Or if you want to reset the current terminal window to use the default settings, you can always just use the following. SQLite will use its default settings in this case. a pipe-separated list with no column headers), you can simply open a new terminal window and run your commands from there. If you need to briefly reset the output to use the SQLite default (i.e. Therefore, I set that column to 16 (which is how many characters the third product uses). In my case, this works fine for the first and third columns, but not for the second column. Specifying 0 sets the column to the greater of three numbers 10, the width of the header, and the width of the first row of data. Using a value of 0 actually makes the column self-adjusting (to a certain point). You may be wondering why I set the first and third columns to zero? Here’s how we can fix the previous example so that the third product isn’t truncated.width 0 16 0 width dot command to set the columns to a specific width. Data that is too wide to fit in a column is truncated. This is because it’s wider than the column’s width.īy default, each column is between 1 and 10 characters wide, depending on the column header name and the width of the first column of data. You might notice that in the previous example, one of the product names has been truncated. If you need to return it to the default format, you can use. mode column to format the results as a column.mode column To add the column names to each column use. So there’s not column headers and it’s displayed as a pipe-separated list. The Default OutputĪs an example, here’s how the SQLite command line interface outputs query results by default: SELECT * FROM Products You might have noticed that the results don’t include the column names, which can make your results confusing if you’re trying to read them, especially if the query returned many columns.įortunately, there’s an easy way to format the output so that it’s displayed as a column with column headers. By default, when you connect to the SQLite command line shell and run a query, the result is returned as a pipe separated list.
