NAME
    App::SQLiteUtils - Utilities related to SQLite

VERSION
    This document describes version 0.005 of App::SQLiteUtils (from Perl
    distribution App-SQLiteUtils), released on 2021-09-13.

DESCRIPTION
    This distribution includes several utilities:

    *   import-csv-to-sqlite

    *   list-sqlite-columns

    *   list-sqlite-tables

FUNCTIONS
  import_csv_to_sqlite
    Usage:

     import_csv_to_sqlite(%args) -> [$status_code, $reason, $payload, \%result_meta]

    Import a CSV file into SQLite database.

    This tool utilizes the "sqlite3" command-line client to import a CSV
    file into SQLite database. It pipes the following commands to the
    "sqlite3" CLI:

     .mode csv
     .import CSVNAME TABLENAME

    where CSVNAME is the CSV filename and TABLENAME is the table name.

    If CSV filename is not specified, will be assumed to be "-" (stdin).

    If table name is not specified, it will be derived from the CSV filename
    (basename) with extension removed. "-" will become "stdin". All
    non-alphanumeric characters will be replaced with "_" (underscore). If
    filename starts with number, "t" prefix will be added. If table already
    exists, a suffix of "_2", "_3", and so on will be added. Some examples:

     CSV filename          Table name         Note
     ------------          ----------         ----
     -                     stdin
     -                     stdin_2            If 'stdinC<already exists
     /path/to/t1.csv       t1
     /path/to/t1.csv       t1_2               If 't1> already exists
     /path/to/t1.csv       t1_3               If 't1C<and>t1_2` already exist
     ./2.csv               t2
     report 2021.csv       report_2021
     report 2021.rev1.csv  report_2021

    Note that the sqlite3 CLI client can be used non-interactively as well.
    You can pipe the commands to its stdin, e.g.:

     % echo -e ".mode csv\n.import /PATH/TO/FILE.CSV TABLENAME" | sqlite3 DB_FILE

    But this utility gives you convenience of picking a table name
    automatically.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   csv_file => *filename* (default: "-")

    *   db_file* => *filename*

    *   table => *str*

    Returns an enveloped result (an array).

    First element ($status_code) is an integer containing HTTP-like status
    code (200 means OK, 4xx caller error, 5xx function error). Second
    element ($reason) is a string containing error message, or something
    like "OK" if status is 200. Third element ($payload) is the actual
    result, but usually not present when enveloped result is an error
    response ($status_code is not 2xx). Fourth element (%result_meta) is
    called result metadata and is optional, a hash that contains extra
    information, much like how HTTP response headers provide additional
    metadata.

    Return value: (any)

  list_sqlite_columns
    Usage:

     list_sqlite_columns(%args) -> any

    See also the ".schema" and ".fullschema" meta-command of the "sqlite3"
    CLI.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   db_file* => *filename*

    *   table* => *str*

    Return value: (any)

  list_sqlite_tables
    Usage:

     list_sqlite_tables(%args) -> any

    See also the ".tables" meta-command of the "sqlite3" CLI.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   db_file* => *filename*

    Return value: (any)

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional
    steps required beyond that are considered a bug and can be reported to
    me.
