Error: Failed to import - Leftover Data

Hi all: I am receiving an error "Failed to import table ... Leftover data ..." I am using a simple BASH script and the mclient tool to import my data from hundreds of CSV files. The fields are pipe | separated, text values are surrounded with double-quotes, and rows end with LF (\n). This is the command I am using to process the files - for csvfile in `ls | grep -i 2018.*\.csv$`; do mclient -d mydatabase -s "COPY INTO table FROM '/path/to/csv/files/$csvfile' USING DELIMITERS '|', '\n', '\"'"; done I have a .monetdb file setup in my home directory so as not to need the username and password. Thanks kindly, Adam Doherty
