archives. A table-valued function, which provides read-only access to existing archives, and a virtual table interface, which provides both read and write access. <h2>Table-Valued Function (read-only access)</h2> <p>For reading existing zip archives, the Zipfile module provides a [table-valued function] that accepts a single argument - the path to the zip archive to be read. For example, to inspect the contents of zip archive "test.zip" from the current directory: <codeblock> SELECT * FROM zipfile('test.zip'); </codeblock> <p>The table-valued function returns one row for each record (file, directory or symbolic link) in the zip archive. Each row has the following columns: <table striped=1> <tr><th>Column Name<th>Contents |

archives. A table-valued function, which provides read-only access to existing archives, and a virtual table interface, which provides both read and write access. <h2>Table-Valued Function (read-only access)</h2> <p>For reading existing zip archives, the Zipfile module provides a [table-valued function] that accepts a single argument. If the argument is a text value, then it is a path to a zip archive to read from the file-system. Or, if the argument is an SQL blob, then it is the zip archive data itself. <p>For example, to inspect the contents of zip archive "test.zip" from the current directory: <codeblock> SELECT * FROM zipfile('test.zip'); </codeblock> <p>Or, from the SQLite shell tool (the [file I/O functions|readfile()] function reads the contents of a file from the file-system and returns it as a blob): <codeblock> SELECT * FROM zipfile( readfile('test.zip') ); </codeblock> <p>The table-valued function returns one row for each record (file, directory or symbolic link) in the zip archive. Each row has the following columns: <table striped=1> <tr><th>Column Name<th>Contents |
