Read a csv file from disk, auto infer options: select * from 'flights.csv'; use the read csv function with custom options: select * from read csv ('flights.csv', delim = '|', header = true, columns = { 'flightdate': 'date', 'uniquecarrier': 'varchar', 'origincityname': 'varchar', 'destcityname': 'varchar' }); read a csv from stdin, auto infer. Some csv files have issues with them. below is a code snippet to save the information in a csv file into a duckdb database, ignoring all the ‘broken’ rows. Running the following command in duckdb cli works in v0.10.1, but not in v0.10.3: select * from 'cad fi utf8.csv'; if the sample size is set to 1 or a number big enough, both work: select * from read csv ('cad fi utf8.csv', sample size= 1); 78864 rows, 41 columns.
