large amounts of comma-separated value content.
The CSV virtual table is also useful as a template source file for
implementing other virtual tables.

<p>
The CVS virtual table is not built into the SQLite amalgamation.
It is available as a
[https://www.sqlite.org/src/artifact?ci=trunk&filename=ext/misc/csv.c|separate source file]
that can be compiled into a [loadable extension].
Typical usage of the CSV virtual table from the
[command-line shell] would be something like this:

<codeblock>
................................................................................

<li><p><b>data=</b><i>TEXT</i>
<p>The <b>data=</b> argument specifies that <i>TEXT</i> is the literal
content of the CSV file.

<li><p><b>schema=</b><i>SCHEMA</i>
<p> The <b>schema=</b> argument specifies a [CREATE TABLE] statement that
the CVS virtual table passes to the [sqlite3_declare_vtab()] interface in
order to define the number and names of the columns in the virtual table.
If both the <b>schema=</b> and the <b>columns=</b> arguments are omitted,
then the CVS virtual table reads the first row of the input content in order
to determine the number of columns and names the columns <b>cNNN</b> where
<b>NNN</b> values are consecutive integers.  It is not allowed to have
both <b>schema=</b> and <b>columns=</b> arguments.

<li><p><b>columns=</b><i>N</i>
<p>The <b>columns=</b><i>N</i> argument causes the virtual table to have
exactly <i>N</i> columns.  If the input data contains more columns than this,
then the excess columns are ignored.  If the input data contains fewer columns,
then extra columns are filled with NULL.
