Here, in this blog, we are going to learn about various types of SQL operators and how they work.&nbsp;<\/p>\n\n\n\n<p>When a WHERE clause is used in a SQL query, the reserved words and characters are known as operators. An operator in SQL can either be a binary operator or a unary operator. When performing a unary operation, the unary operator only needs one operand, whereas when doing a binary operation, the binary operator needs two operands.&nbsp;<\/p>\n\n\n\n<p>An essential part of defining a condition in a SQL query is connecting two or more conditions, which is done with the help of operators. The role of operators in SQL is to manipulate the data and generate a result set on the basis of the used SQL operator\u2019s functionality. There are different types of SQL operators depending upon the operation they perform.&nbsp;<\/p>\n\n\n\n    <div class=\"courses-cta-container\">\n        <div class=\"courses-cta-card\">\n            <div class=\"courses-cta-header\">\n                <div class=\"courses-learn-icon\"><\/div>\n                <span class=\"courses-learn-text\">Academy Pro<\/span>\n            <\/div>\n            <p class=\"courses-cta-title\">\n                <a href=\"https:\/\/www.mygreatlearning.com\/academy\/premium\/practical-sql-training\" class=\"courses-cta-title-link\">SQL Course<\/a>\n            <\/p>\n            <p class=\"courses-cta-description\">Master SQL and Database management with this SQL course: Practical training with guided projects, AI support, and expert instructors.<\/p>\n            <div class=\"courses-cta-stats\">\n                <div class=\"courses-stat-item\">\n                    <div class=\"courses-stat-icon courses-user-icon\"><\/div>\n                    <span>7 Hrs<\/span>\n                <\/div>\n                <div class=\"courses-stat-item\">\n                    <div class=\"courses-stat-icon courses-star-icon\"><\/div>\n                    <span>2 Projects<\/span>\n                <\/div>\n            <\/div>\n            <a href=\"https:\/\/www.mygreatlearning.com\/academy\/premium\/practical-sql-training\" class=\"courses-cta-button\">\n                Take SQL Course Now\n                <div class=\"courses-arrow-icon\"><\/div>\n            <\/a>\n        <\/div>\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"types-of-sql-operators\"><strong>Types of SQL Operators<\/strong><\/h2>\n\n\n\n<p>Operators in SQL are categorized on the basis of the operation they are responsible to perform.

In SQL, the equality of two expressions is verified using comparison operators. It determines whether two expressions are equivalent to one another. In the WHERE clause of a SQL query, comparison operators are typically made use of. A comparison operation can produce the results TRUE, FALSE, or UNKNOWN. If any one of the expressions or both of them are NULL, the operation returns UNKNOWN. All expression kinds, with the exception of those containing text, ntext, or images, could employ these operators.<\/p>\n\n\n\n<p>Look at the table below to know what all comparison operators are allowed in SQL.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><tbody><tr><td><strong>Operator<\/strong><\/td><td><strong>Operation&nbsp;<\/strong><\/td><td><strong>Explanation<\/strong><\/td><\/tr><tr><td>&gt;<\/td><td>Greater than<\/td><td>This operator checks if the left operand is greater than the right operand.<\/td><\/tr><tr><td>&lt;<\/td><td>Less than<\/td><td>This operator checks if the left operand is less than the right operand.<\/td><\/tr><tr><td>=<\/td><td>Equal to&nbsp;<\/td><td>This operator checks if the values of the operands on both sides of the operator are the same.<\/td><\/tr><tr><td>&gt;=<\/td><td>Greater than or equal to<\/td><td>It checks for the value of the left operand to be greater than or equal to the value of the right-hand operand.<\/td><\/tr><tr><td>&lt;=<\/td><td>Less than or equal to<\/td><td>It checks for the value of the left-hand operand to be less than or equal to the value of the right-hand operand.<\/td><\/tr><tr><td>&lt; &gt; or!=<\/td><td>Not equal to<\/td><td>This operator checks for inequality and returns TRUE if the left and right operands are not equal to each other.<\/td><\/tr><tr><td>!&gt;<\/td><td>Not greater than<\/td><td>This operator returns TRUE if the left-hand operand is not greater than the right-hand operand.

We can combine multiple SQL operators together in a single SQL query to make the retrieval of data more specific, but in such cases, it is significant to put the operators in the query while keeping the precedence of operators in mind. Precedence of operators tells the sequence in which different operators will operate in a query in accordance with their priority level in SQL. The arithmetic and compound operators are always given the highest precedence, followed by comparison and logical operators.&nbsp;<\/p>\n\n\n\n<p>The precedence for some of the commonly used SQL operators has been given below:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted has-cyan-bluish-gray-background-color has-background\">= \ud83e\udc7a &lt; \ud83e\udc7a &gt; \ud83e\udc7a &lt;= \ud83e\udc7a &gt;= \ud83e\udc7a &lt;&gt; \ud83e\udc7a!= \ud83e\udc7a ~= \ud83e\udc7a ^= \ud83e\udc7a IS NULL \ud83e\udc7a LIKE \ud83e\udc7a BETWEEN \ud83e\udc7a IN<\/pre>\n\n\n\n<p>As you might have observed from the examples cited above, SQL operators make it convenient and time-saving for us to filter out data based on certain conditions. Now that you know how each type of operator works in SQL, you\u2019ll be able to identify which operator meets the demand of the query perfectly in a particular situation. You will also be capable of putting using the operators in the right sequence on the basis of their precedence order. So, go ahead and try your hands on all sorts of queries in SQL and polish your knowledge of SQL operators you have gained so far.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"frequently-asked-questions-faqs\"><strong>Frequently Asked Questions (FAQs)<\/strong><\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1659846169061\"><strong class=\"schema-faq-question\"><strong>How many SQL operators are there?<\/strong><\/strong> <p class=\"schema-faq-answer\">SQL operators are broadly divided into 4 categories; each has numerous operators that can be used for different purposes in SQL that add up to more than 30 operators in total, for example, addition, greater than, negation, and so on.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1659846193484\"><strong class=\"schema-faq-question\"><strong>What are the different types of operations in SQL?<\/strong><\/strong> <p class=\"schema-faq-answer\">The different types of operations in SQL are precise as follows \u2013 arithmetic operations, logical operations, compound operations, comparison, operators, and bitwise operations.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1659846205917\"><strong class=\"schema-faq-question\"><strong>What are SQL operators and how do they work?<\/strong><\/strong> <p class=\"schema-faq-answer\">There are some reserved keywords in SQL that are used in combination with the WHERE clause in a SQL query.
