8 Powerful SQL Aggregate Functions You Must Master for Effective Data Analysis


SQL Aggregate Functions are powerful programming functions used to manipulate multiple pieces of data stored in a database

[{"selector":"#anim-b0bc5a17-6004-4bcf-99cd-bfc5846c5340 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

In other words, they allow users to calculate and analyze large data sets by generating a single quantity from a group of rows

[{"selector":"#anim-2e02c1a5-ee56-49f7-8d86-5eef1165f963 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

SQL Aggregate functions, are the primary source for report, data analysis, and discovering information from linked databases

[{"selector":"#anim-6f69fd74-0135-4195-8985-6c816cf574ac [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

The COUNT() function is used to count the number of rows in a table or non-NULL values in a specific column

[{"selector":"#anim-79113fed-b744-46e9-8eef-df063083f2e3 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

The SUM() function computes the grand total sum of a numeric column

[{"selector":"#anim-8dab8e9d-fe1a-485d-8d44-a03b28003ddb [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

The AVG() function is used for computing the average or mean value of the numeric data in a specific column

[{"selector":"#anim-cda46b3c-02ef-41c0-a497-8519bd0ab41e [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0, -8.928571179351586%, 0) translate(0%, -25%) scale(1.5)","translate3d(0, 0%, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]
