Explains how to perform single and multiple calculations in SELECT, rename computed results with AS, and retrieve either whole tables or specific columns with correct clause precedence. Includes examples for limiting rows, adding single-line and block comments, and constructing joins using INNER, LEFT, RIGHT, and FULL OUTER join patterns. Also demonstrates ORDER BY sorting by position, subqueries with limits, combining columns via string concatenation, filtering with LIKE, and conditional logic using CASE and WITH common table expressions.",{"@graph":63,"@context":118},[64,80,101],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":11,"@type":70,"position":76},"https://docshare.wps.com/template/presentations/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/sql-cheat-sheet-fundamentals-quick-sql-syntax-guide/573231/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/sql-cheat-sheet-fundamentals-quick-sql-syntax-guide/573231.png","ImageObject",442,249,{"name":88,"@type":89},"Riley West","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-18","2026-10-13",true,{"@type":98,"interactionType":99,"userInteractionCount":79},"InteractionCounter",{"@type":100},"ViewAction",{"@type":102,"mainEntity":103},"FAQPage",[104,110,114],{"name":105,"@type":106,"acceptedAnswer":107},"How should SQL clauses be ordered when writing a query?","Question",{"text":108,"@type":109},"SQL requires clauses in a specific order of precedence, including FROM before SELECT and LIMIT being applied after.
