DESCRIPTION

TSV/CSV is a friend of text processing. RDBMS/SQL is a friend of analyzing data. I quite often create a working table from a TSV/CSV file. This tiny script is created for the purpose. By this script, CSV/TSV contents are loaded into a database table via DBI.

OPTIONS

-h

Show POD help.

-t <separator>

Specify field separator. Defaults to ',' (a comma). This is passed to split. NOTE that field separation is currently done by just a split. Thus, quoting is not correctly handled.

-c

Clear the specified table before contents loading.

-u <username>

Specify username.

-p <password>

Specify password.

<connection>

Specify DBI connection string.

<table>

Specify table name.

<schema>

Specify table schema optionally. This is appended to 'CREATE TABLE <table>' SQL. Expected to be as \(.*\).

<files>...

Specify CSV/TSV files. If omitted or '-' is specified, STDIN is used.
