It can be used with numeric, date, and even string columns (where it returns the lexicographically smallest value), but it&#8217;s most commonly applied to numeric columns to find the smallest number.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">How <code>MIN()<\/code> works:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When you apply <code>MIN()<\/code> to a column in a table, it scans all the rows in the result set and returns the smallest value found in that column.<\/li>\n\n\n\n<li>It ignores <code>NULL<\/code> values by default, meaning it only considers non-null values when calculating the minimum.<\/li>\n\n\n\n<li><code>MIN()<\/code> can be used alone on a table to get the smallest value overall, or it can be used with <code>GROUP BY<\/code> to get the smallest value per group.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Example usage:<\/h4>\n\n\n\n<p>Suppose you have a table called <code>Sales<\/code> with a column <code>Amount<\/code> that stores the sales amount for each transaction:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>SELECT MIN(Amount) AS SmallestSale\nFROM Sales;\n<\/code><\/pre>\n\n\n\n<p>This query returns the smallest sales amount in the <code>Sales<\/code> table.<\/p>\n\n\n\n<p>If you want the smallest sale amount per sales region, assuming there is a <code>Region<\/code> column, you can do:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>SELECT Region, MIN(Amount) AS SmallestSale\nFROM Sales\nGROUP BY Region;\n<\/code><\/pre>\n\n\n\n<p>This groups the sales by region and returns the smallest sale amount for each region.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Why is <code>MIN()<\/code> important?<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It helps in quickly finding the minimum value in a dataset without writing complex queries.<\/li>\n\n\n\n<li>Useful in data analysis, reporting, and decision-making, such as finding the lowest price, the earliest date, or the smallest quantity.<\/li>\n\n\n\n<li>Efficiently implemented in database engines to work on large datasets.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>MIN()<\/code> is the correct built-in SQL function to get the smallest value from a numeric column.<\/li>\n\n\n\n<li>It ignores NULLs and can work with or without grouping.<\/li>\n\n\n\n<li>It&#8217;s fundamental for data aggregation and analysis tasks in SQL queries.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>in an sql query which built in function is used to obtain the smallest vakue of number columns The correct answer and explanation is: The built-in SQL function used to obtain the smallest value of a numeric column is: Explanation: The MIN() function in SQL is an aggregate function that returns the smallest (minimum) value [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-18211","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/18211","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=18211"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/18211\/revisions"}],"predecessor-version":[{"id":18212,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/18211\/revisions\/18212"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=18211"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=18211"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=18211"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
