Common parameters of mysqlimport:

-- user=user_name,-u user name that connects to the Mysql server

-- password [= password],-p password

-- host=hostname,-h the host where the connected MySQL server resides

-- port=port_num, the TCP/IP port number of the-P connection

-- socket=path,-S for connections to hosts, socket files used by Unix, named pipes used by Windows

-- default-character-set=charset_name default character set

-- delete,-D clear the table before importing the text file. This option should be carefully selected.

-- force,-f ignores errors. For example, if part of the import in the text file does not match the table to be imported, the import operation will continue with the import of other matching parts and will not be terminated; if this parameter is not available, mysqlimport will exit the import

-- ignore,-I if there are duplicate values during import, the duplicate values will be skipped

-- replace,-r if there are duplicate values in the import process, the duplicate values will be overwritten

-- local,-L reads the input file locally on the client

-- lock-tables,-l lock all tables to be written before importing the text file

-- silent,-s silent mode. The result will be output only if an error occurs

-- ignore-lines=N skips the first N lines in the text file

When use-threads=N imports a text file, it uses several parallel threads

-- Delimiter in fields-terminated-by imported text file

-- fields-enclosed-by specifies the symbol used to contain column values, which is useful for character columns, or for scenarios with column delimiters in the middle of characters
