DESCRIPTION

This makes a report in HTML format, of a single table from an SQLite database. One can also create a non-HTML report if one gives a certain combination of options, but this is more oriented towards HTML reports.

OPTIONS

--all_pages

Make a multi-page report, generating all pages, by page-number. The --limit and --outfile options are required for this.

--database

The name of the database file to use. (required)

--distinct

If columns are given to show (see show), then this will ensure that rows with exactly the same values will not be repeated.

--groups

Group template(s) (or filenames of files containing group templates). A group template is a template for values which are ``grouped'' under a corresponding header. The first group in the array is placed just after the first header in the report, and so on.

This argument can be repeated.

See headers for more information.

--headers

An array of header templates (or filenames of files containing header templates). A header template lays out what values should be put into headers rather than the body of the report. The first header template is given a H1 header, the second a H2 header, and so on. Headers are shown only when the value(s) they depend on change, but they get their values from each row in the report. Therefore the columns used in the headers should match the columns used in the sort_by array.

The column names are the variable names in this template. This has a different format to the report_template; it is more sophisticated.

The format is as follows:

{$colname}

A variable; will display the value of the column, or nothing if that value is empty.

{?colname stuff [$colname] more stuff}

A conditional. If the value of 'colname' is not empty, this will display ``stuff value-of-column more stuff''; otherwise it displays nothing.

     {?col1 stuff [$col1] thing [$col2]}
 
 

This would use both the values of col1 and col2 if col1 is not empty.

{?colname stuff [$colname] more stuff!!other stuff}

A conditional with ``else''. If the value of 'colname' is not empty, this will display ``stuff value-of-column more stuff''; otherwise it displays ``other stuff''.

This version can likewise use multiple columns in its display parts.

     {?col1 stuff [$col1] thing [$col2]!![$col3]}
 
 

The same format is used for groups and row_template.

--help

Print help message and exit.

--index_template

Similar to the report_template, but this is used for the index-pages in multi-page and split reports. It has the same format, but it can be useful to have them as two separate templates as one may wish to change the way the title is treated for indexes versus actual reports.

--layout

The layout of the report. This determines both how rows are grouped, and what is in the generated row_template if no row_template is given.

table

The report is a (group of) tables, each row of the report is a row in the table; a new table occurs after the heading(s).

para

The report is in paragraphs, each row of the report is one paragraph.

list

The report is a (group of) lists, each row of the report is an item in the list; a new list occurs after the heading(s).

fieldval

The rows are not HTML-formatted. The generated row_template is made up of Field:Value pairs, one on each line.

none

The rows are not HTML-formatted. The generated row_template is made up of values, one on each line.

--limit

The maximum number of rows to display per page. If this is zero, then all rows are displayed in one page.

--link_suffix string

The 'link_suffix' argument, if given, overrides the suffix given in links to the other pages in a multi-page report; this is useful if you're post-processing the files (and thus changing their extensions) or are using something like Apache MultiViews to eliminate the need for extensions in links.

     --link_suffix '.shtml'
 
 

     --link_suffix ''
 
 

--manpage

Print the full help documentation (manual page) and exit.

--not_where

A hash containing the column names where the selection criteria in where should be negated.

--outfile

The name of the output file. If this is not given, or the name is '-' then the output goes to STDOUT.

--page

Select which page to generate, if limit is not zero.

--report_style

The style of the report, especially as regards table layout.

full

medium

compact

bare

--report_template

Either a string containing a template, or string containing the name of a template file. The template variables are in the following format:

<!--sqlr_title-->

The following variables are set for the report:

sqlr_title

Title (generally the table name).

sqlr_contents

The report itself.

--row_ids

The default column-name which identifies rows in SQLite is 'rowid', but for tables which have a primary integer key, this doesn't work (even though the documentation says it ought to). Therefore it is necessary to identify, for the given database, which tables need to use a different column-name for this. (This can be repeated)

--row_template

The template for each row. This uses the same format as for headers. If none is given, then a default row_template will be generated, depending on what layout and which columns are going to be shown (see show).

Therefore it is important that if one provides a row_template, that it matches the current layout.

Also note that if a column is given in a header, it will not be displayed in a row, even if it is put into the row_template.

--show

An array of columns to select; also the order in which they should be shown when a row_template has not been given. If this option is not used, all columns in the table will be shown.

--sort_by

An array of column names by which the result should be sorted. (Repeat the argument for each new value)

--sort_reversed

A hash of column names where the sorting given in sort_by should be reversed.

--split_col

Generate a multi-page report where pages are split by the value of the given column (as well as by page-number if a limit is given)

--split_alpha

If one is generating a split_col report, giving the 'split_alpha' option splits the report not by the distinct values of that column, but by truncated values of the column; giving a split_alpha value of 1 takes only the first letter, and so on.

--table

The table to report on. (required)

--table_border

For fine-tuning the report_style; if the layout is 'table', then this overrides the default border-size of the table.

--table_header

When the report layout is 'table' and the report_style is not 'bare', then this argument can be used to customize the table-header of the report table. This must either contain the contents of the table-header, or the name of a file which contains the contents of the table-header.

If this argument is not given, the table-header will be constructed from the column names of the columns to be shown.

--title

The title of the report; if this is empty, a title will be generated.

--total

Just print the total matching rows, then exit.

--truncate_colnames

For fine-tuning the report_style; this affects the length of column names given in layouts which use them, that is, 'table' (for all styles except 'bare') and 'para'. If the value is zero, the column names are not truncated at all; otherwise they are truncated to that number of characters.

--verbose

Print informational messages.

--version

Print version information and exit.

--where

A hash containing selection criteria. The keys are the column names and the values are strings suitable for using in a LIKE condition; that is, '%' is a multi-character wildcard, and '_' is a single-character wildcard. All the conditions will be ANDed together.

Yes, this is limited and doesn't use the full power of SQL, but it's useful enough for most purposes.

--use_package

An array of package names of packages to ``use''. This is mainly so that the {&funcname())} construct of the templates (see SQLite::Work::Template) can call functions within these packages (using their fully-qualified names).

REQUIRES

     Getopt::Long
     Pod::Usage
     Getopt::ArgvFile
     SQLite::Work;
