How Can I Efficiently Retrieve Column Names from an SQLite3 Database During Migration?

Accessing Column Names in SQLite3 Databases During Migration

Migrating an iPhone app to a newer database version often requires confirming the presence of specific columns, especially when prior database versions aren't available. While a SELECT query targeting sqlite_master can achieve this, it necessitates parsing the results – a less efficient and more complex approach.

A superior method leverages the PRAGMA table_info() statement:

<code class="language-sql">PRAGMA table_info(table_name);</code>

This directly returns a list of all columns in the designated table. Its simplicity and efficiency make it the ideal solution for retrieving column names during SQLite3 database migrations.
