CPAN::SQLite::Populate \- create and populate database tables
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is responsible for creating the tables
(if \f(CW\*(C`setup\*(C'\fR is passed as an option) and then for 
inserting, updating, or deleting (as appropriate) the
relevant information from the indices of
\&\fICPAN::SQLite::Info\fR and the
state information from \fICPAN::SQLite::State\fR. It does
this through the \f(CW\*(C`insert\*(C'\fR, \f(CW\*(C`update\*(C'\fR, and \f(CW\*(C`delete\*(C'\fR
methods associated with each table.
.PP
Note that the tables are created with the \f(CW\*(C`setup\*(C'\fR argument
passed into the \f(CW\*(C`new\*(C'\fR method when creating the
\&\f(CW\*(C`CPAN::SQLite::Index\*(C'\fR object; existing tables will be
dropped.
.SH "TABLES"
.IX Header "TABLES"
The tables used are described below \- the data types correspond
to mysql tables, with the corresponding adjustments made if
the SQLite database is used.

.IX Subsection "mods"
This table contains module information, and is created as

\&  chapterid INTEGER
.Ve
.IP "\(bu" 3
mod_id
.Sp
This is the primary (unique) key of the table.
.IP "\(bu" 3
dist_id
.Sp
This key corresponds to the id of the associated distribution
in the \f(CW\*(C`dists\*(C'\fR table.
.IP "\(bu" 3
mod_name
.Sp
This is the module's name.
.IP "\(bu" 3
mod_abs
.Sp
This is a description, if available, of the module.
.IP "\(bu" 3
mod_vers
.Sp
This value, if present, gives the version of the module.
.IP "\(bu" 3
dslip
.Sp
This is a 5 character string expressing the dslip
(development, support, language, interface, public
license) information.
.IP "\(bu" 3
chapterid
.Sp
This number corresponds to the chapter id of the module,
if present.
.SS "dists"
.IX Subsection "dists"
This table contains distribution information, and is created as
.PP

\&  dist_id INTEGER NOT NULL PRIMARY KEY
\&  dist_name VARCHAR(90) NOT NULL
\&  auth_id INTEGER NOT NULL
\&  dist_file VARCHAR(110) NOT NULL

\&  dist_abs TEXT
\&  dist_dslip VARCHAR(5)
.Ve
.IP "\(bu" 3
dist_id
.Sp
This is the primary (unique) key of the table.
.IP "\(bu" 3
auth_id
.Sp
This corresponds to the \s-1CPAN\s0 author id of the distribution
in the \f(CW\*(C`auths\*(C'\fR table.
.IP "\(bu" 3
dist_name
.Sp
This corresponds to the distribution name (eg, for
\&\fIMy\-Distname\-0.22.tar.gz\fR, \f(CW\*(C`dist_name\*(C'\fR will be \f(CW\*(C`My\-Distname\*(C'\fR).
.IP "\(bu" 3
dist_file
.Sp
This corresponds to the \s-1CPAN\s0 file name.
.IP "\(bu" 3
dist_vers
.Sp
This is the version of the \s-1CPAN\s0 file (eg, for
\&\fIMy\-Distname\-0.22.tar.gz\fR, \f(CW\*(C`dist_vers\*(C'\fR will be \f(CW0.22\fR).
.IP "\(bu" 3
dist_abs
.Sp
This is a description of the distribtion. If not directly
supplied, the description for, eg, \f(CW\*(C`Foo::Bar\*(C'\fR, if present, will 
be used for the \f(CW\*(C`Foo\-Bar\*(C'\fR distribution.
.IP "\(bu" 3
dist_dslip
.Sp
This is a 5 character string expressing the dslip
(development, support, language, interface, public
license) information. Normally this comes from the
module name; this value for the distribution name
comes in simple cases where the module name
matches the distribution name by a substitution of
\&\f(CW\*(C`::\*(C'\fR by \f(CW\*(C`\-\*(C'\fR.
.SS "auths"
.IX Subsection "auths"
This table contains \s-1CPAN\s0 author information, and is created as
.PP
.Vb 4
\&  auth_id INTEGER NOT NULL PRIMARY KEY
\&  cpanid VARCHAR(20) NOT NULL
\&  fullname VARCHAR(40) NOT NULL
\&  email TEXT
.Ve
.IP "\(bu" 3
auth_id
.Sp
This is the primary (unique) key of the table.
.IP "\(bu" 3
cpanid
.Sp
This gives the \s-1CPAN\s0 author id.
.IP "\(bu" 3
fullname
.Sp
This is the full name of the author.
.IP "\(bu" 3
email
.Sp
This is the supplied email address of the author.
.SS "chaps"
.IX Subsection "chaps"
This table contains chapter information associated with
distributions. \s-1PAUSE\s0 allows one, when registering modules,
to associate a chapter id with each module (see the \f(CW\*(C`mods\*(C'\fR
table). This information is used here to associate chapters
(and subchapters) with distributions in the following manner.
Suppose a distribution \f(CW\*(C`Quantum\-Theory\*(C'\fR contains a module
\&\f(CW\*(C`Beta::Decay\*(C'\fR with chapter id \f(CW55\fR, and
another module \f(CW\*(C`Laser\*(C'\fR with chapter id \f(CW87\fR. The
\&\f(CW\*(C`Quantum\-Theory\*(C'\fR distribution will then have two
entries in this table \- \f(CW\*(C`chapterid\*(C'\fR of \fI55\fR and
\&\f(CW\*(C`subchapter\*(C'\fR of \fIBeta\fR, and \f(CW\*(C`chapterid\*(C'\fR of \fI87\fR and
\&\f(CW\*(C`subchapter\*(C'\fR of \fILaser\fR.
.PP
The table is created as follows.
.PP
.Vb 4
\&  chap_id INTEGER NOT NULL PRIMARY KEY
\&  chapterid INTEGER
\&  dist_id INTEGER NOT NULL

.IP "\(bu" 3
chapterid
.Sp
This number corresponds to the chapter id.
.IP "\(bu" 3
dist_id
.Sp
This is the id corresponding to the distribution in the
\&\f(CW\*(C`dists\*(C'\fR table.
.IP "\(bu" 3
subchapter
.Sp
This is the subchapter.
