In this php crud tutorial
In this php crud tutorial we'll explain the php crud operation using mysqli.
A CRUD operation is a SQL query of one of the following types:
1. INSERT (C)
2. SELECT (R)
3. UPDATE (U)
4. DELETE (D)
Whenever one of those four SQL queries are run, we have a CRUD operation.
We provided a couple of sql interview questions for your next sql interview below:
Q: What is CRUD?
A: CRUD are four sql queries that are abbreviated.
CRUD:
Create SQL queries (INSERT SQL queries)
Read SQL queries (SELECT SQL queries)
UPDATE SQL queries
DELETE SQL queries
Q: What are some of the main database slowness reasons?
A: We've already made a video on this, but the main database slowness reasons are as follows:
1. Selecting too much data
2. Selecting unnecessary data
3. Scanning through many unnecessary rows
To reduce slow sql queries, make sure to use sql indexes.
