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.
