Here&#8217;s the syntax of the <code><code>RPAD<\/code>()<\/code> function:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"SQL (Structured Query Language)\" data-shcb-language-slug=\"sql\"><span><code class=\"hljs language-sql\">RPAD(string, length, pad_string)<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-1\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">SQL (Structured Query Language)<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">sql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this syntax:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>string<\/code>: The input string that you want to right-pad.<\/li>\n\n\n\n<li><code>length<\/code>: The total length of the resulting string after padding.<\/li>\n\n\n\n<li><code><code>pad_string<\/code><\/code>: The character or string that you use for padding.<\/li>\n<\/ul>\n\n\n\n<p>The <code>RPAD()<\/code> function returns the string, right-padded with the string <code>pad_string<\/code> to a length of <code>length<\/code> characters.<\/p>\n\n\n\n<p>If the string is longer than the length, the <code>RPAD()<\/code> function shortens the string to the length character.<\/p>\n\n\n\n<p>If any argument string, length, or <code>pad_string<\/code> is <code><code>NULL<\/code><\/code>, the <code>RPAD()<\/code> function returns <code><code><a href=\"https:\/\/www.mysqltutorial.org\/mysql-basics\/mysql-null\/\">NULL<\/a><\/code><\/code>.<\/p>\n\n\n\n<p class=\"note\">Note that <code>RPAD()<\/code> works with multibyte character encodings such as UTF-8 or UTF-16.<\/p>\n\n\n\n<p>The <code>RPAD<\/code> function is useful when you need to format strings with a consistent length, align text in columns, or prepare data for display.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">MySQL RPAD function examples<\/h2>\n\n\n\n<p>Let&#8217;s take some examples of using the MySQL <code>RPAD<\/code> function.<\/p>\n\n\n\n<h3
