Query Caching Development Tutorials, Guides & Insights

Efficient SELECT statements can greatly improve query performance.

Avoid using SELECT * as it retrieves all columns, consuming more resources than necessary. Specify only the columns you need.

• Primary Index: Created automatically with a primary key.
• Unique Index: Ensures indexed column values are unique.
• Composite Index: An index on multiple columns.
• Full-text Index: Supports full-text search in text-heavy fields.
• Clustered Index: Sorts and stores table rows based on the index.
• Non-clustered Index: A separate structure from the table.

CREATE INDEX index_name
ON table_name (column1, column2);
