SQLite EXPLAIN Statement
SQLite EXPLAIN Statement
In this tutorial, we will learn about the SQLite EXPLAIN statement. The SQLite EXPLAIN statement provides information about the query execution plan. It reports the sequence of operations performed to retrieve the query results. EXPLAIN’s output is useful for analyzing and optimizing SQLite queries.
Syntax
The general syntax of the EXPLAIN command is as follows:
EXPLAIN <Query>
or
EXPLAIN QUERY PLAN <Query>
For example,
EXPLAIN [QUERY PLAN] SELECT column1, column2, … FROM table_name
WHERE <condition>;
Example
sqlite> EXPLAIN SELECT * FROM emp;
This statement is used to get insights into how the database engine intends to execute the query, and this information can help optimize queries, understand index usage, and identify performance bottlenecks.
