How Can I Efficiently Retrieve a List of Column Names from an SQLite3 Table?

Efficiently Fetching Column Names from an SQLite3 Table

Database migrations often require verifying the existence of specific columns. This article explores the most efficient method for retrieving a complete list of column names from an SQLite3 table.

While querying sqlite_master is possible, extracting column names from the resulting sql string requires additional processing, making it less efficient.

A superior approach leverages SQLite3's built-in PRAGMA table_info() function:

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

This directly returns a table with a name column containing all column names for the specified table_name. This method is significantly more streamlined and avoids the overhead of parsing SQL strings.

The above is the detailed content of How Can I Efficiently Retrieve a List of Column Names from an SQLite3 Table?. For more information, please follow other related articles on the PHP Chinese website!
