VARCHAR Type"},"content":{"rendered":"\n<p><strong>Summary<\/strong>: in this tutorial, you&#8217;ll learn how to use PostgreSQL <code>VARCHAR<\/code> type to store variable-length strings in the database.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id='getting-started-with-postgresql-varchar-type'>Getting Started with PostgreSQL VARCHAR Type <a href=\"#getting-started-with-postgresql-varchar-type\" class=\"anchor\" id=\"getting-started-with-postgresql-varchar-type\" title=\"Anchor for Getting Started with PostgreSQL VARCHAR Type\">#<\/a><\/h2>\n\n\n\n<p>The <code>CHARACTER VARYING<\/code> type, or <code>VARCHAR<\/code>, allows you to store variable-length strings in the database.<\/p>\n\n\n\n<p>Here&#8217;s the syntax for defining a column with the <code>CHARACTER VARYING<\/code> type:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"PostgreSQL SQL dialect and PL\/pgSQL\" data-shcb-language-slug=\"pgsql\"><span><code class=\"hljs language-pgsql\"><span class=\"hljs-built_in\">column_name<\/span> <span class=\"hljs-type\">CHARACTER<\/span> <span class=\"hljs-type\">VARYING<\/span> (n)<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-1\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PostgreSQL SQL dialect and PL\/pgSQL<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">pgsql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In practice, you often use <code>VARCHAR<\/code> a synonym of the <code>CHARACTER VARYING<\/code> type:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-2\" data-shcb-language-name=\"PostgreSQL SQL dialect and PL\/pgSQL\" data-shcb-language-slug=\"pgsql\"><span><code class=\"hljs language-pgsql\"><span class=\"hljs-built_in\">column_name<\/span> <span class=\"hljs-type\">VARCHAR<\/span>(n)<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-2\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PostgreSQL SQL dialect and PL\/pgSQL<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">pgsql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this syntax, specify the length specifier (<code>n<\/code>) that is the maximum number of characters the <code>VARCHAR<\/code> column can store. <code>n<\/code> is a positive integer and cannot exceed <code>10,485,760<\/code>.<\/p>\n\n\n\n<p>If you attempt to <a href=\"https:\/\/www.pgtutorial.com\/postgresql-tutorial\/postgresql-insert\/\">insert<\/a> or <a href=\"https:\/\/www.pgtutorial.com\/postgresql-tutorial\/postgresql-update\/\">update<\/a> a string with more than <code>n<\/code> characters into the column, PostgreSQL will issue an error.<\/p>\n\n\n\n<p>There are two main reasons you want to limit the length of the strings stored in the database:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>First, you want to create a validation rule at the database level so that the string length cannot exceed a certain length.<\/li>\n\n\n\n<li>Second, you want the app&#8217;s user interface broken due to a very long string.<\/li>\n<\/ul>\n\n\n\n<p>Unlike the <a href=\"https:\/\/www.pgtutorial.com\/postgresql-tutorial\/postgresql-char\/\">CHAR<\/a> column, PostgreSQL does not pad spaces if the values stored in the <code>VARCHAR<\/code> column have a length of less than <code>n<\/code>.<\/p>\n\n\n\n<p>If you want to store a string with any length, you can omit the length specifier in the column definition:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-3\" data-shcb-language-name=\"PostgreSQL SQL dialect and PL\/pgSQL\" data-shcb-language-slug=\"pgsql\"><span><code class=\"hljs language-pgsql\"><span class=\"hljs-built_in\">column_name<\/span> <span class=\"hljs-type\">VARCHAR<\/span><\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-3\"><span class=\"shcb-language__label\">Code

class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this case, the <code>column_name<\/code> can store strings of any length.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id='postgresql-varchar-type-example'>PostgreSQL VARCHAR type example <a href=\"#postgresql-varchar-type-example\" class=\"anchor\" id=\"postgresql-varchar-type-example\" title=\"Anchor for PostgreSQL

class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>The <code>products<\/code> table has two <code>VARCHAR<\/code> columns:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <code>name<\/code> column can store up to 50 characters. If you attempt to insert or update strings with a length greater than 50, PostgreSQL will issue an error.<\/li>\n\n\n\n<li>The <code>description<\/code> column can store a string of any length.<\/li>\n<\/ul>\n\n\n\n<p>The <code>name<\/code> column has a length limit to ensure product names can be displayed clearly on receipts. Without this limit, product names may overlap with other information.<\/p>\n\n\n\n<p>Second, insert some rows into the <code>products<\/code> table:<\/p>\n\n\n<pre class=\"wp-block-code\"
