Is SQL a coding?

What are three advantages to using SQL?
Some advantages of SQL are as follows:Faster Query Processing – Large amount of data is retrieved quickly and efficiently. … No Coding Skills – For data retrieval, large number of lines of code is not required. … Standardised Language – … Portable – … Interactive Language – … Multiple data views –
Is SQL better than Excel?
SQL is much faster than Excel. … Excel can technically handle one million rows, but that’s before the pivot tables, multiple tabs, and functions you’re probably using. SQL also separates analysis from data. When using SQL, your data is stored separately from your analysis.
