Changeset: 71f3eba34a1b for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB/rev/71f3eba34a1b
Added Files:
sql/test/file_loader/Tests/cars.csv
sql/test/file_loader/Tests/cars.psv
sql/test/file_loader/Tests/cars.tsv
sql/test/file_loader/Tests/cars_semicolon.csv
sql/test/file_loader/Tests/file_loader_field_separator.test.in
Modified Files:
sql/test/file_loader/Tests/All
Branch: default
Log Message:
Adding data files with different field separators and extensions, and test to
read those data files.
Currently the file_loader fails to recognise the field separator correctly.
Also it does not recognise .tsv or .psv extensions.
