The IMPORT Statement

The IMPORT statement allows you to import tables from external data sources, like CSV files or a MySQL database. The general syntax of the IMPORT statement is:

IMPORT TABLE <table> [, <table>]... FROM <source_url>;

The source url specifies the external source from which the tables should be imported. For example, to import the table mytable from a remote MySQL database:

IMPORT TABLE mytable FROM 'mysql://localhost:3306/mydatabase';
SELECT * FROM mytable;

Or to import a CSV file:

IMPORT TABLE measurements FROM 'csv://measurements.csv?headers=true';
SELECT * FROM measurements;

CSV Files

Use the csv:// source url prefix to import from csv files. The url format for csv files is:

quote_char the CSV row quote char (default is ")
col_sep the CSV column separator char (default is ,)
row_sep the CSV row separator char (default is \n)
escape_char the CSV row scape char (default is \)
