The following example returns all rows in the HumanResources.Department table that have a value in DepartmentID that is greater than or equal to the value 13. Unlike the = (equality) comparison operator, the result of the >= comparison of two NULL values does not depend on the ANSI_NULLS setting. Operator Description & Bitwise AND Bitwise OR Bitwise exclusive OR Operator Description + Add equals - Subtract equals Multiply equals / Divide equals. When you compare nonnull expressions, the result is TRUE if the left operand has a greater or equal value than the right operand otherwise, the result is FALSE. The conversion depends on the rules of data type precedence. SELECT FROM vacationuser WHERE (ENDDATE < (SYSDATE + 2 DAY)) SELECT EMAIL from vacationusers WHERE ENDDATE < DATEADD (day, +2, CURRENTDATE) AND ENDDATE > CURRENTDATE. Compares two expressions to determine whether the left expression has a value less than or equal to the right.Both expressions must have implicitly convertible data types. SELECT FROM employees WHERE employeeid < 500 In this example, the SELECT statement would return all rows from the employees table where the employeeid is less than or equal to 500. If the left-hand operator is not greater than the right-hand operator then the condition becomes true and it will return the matched records.To view Transact-SQL syntax for SQL Server 2014 and earlier, see Previous versions documentation. In SQL Server, you can use the < operator to test for an expression less than or equal to. In SQL Server, The Not Greater Than (!>) operator is used to check whether the left-hand operator is not greater than the right-hand operator or not. For example, you can use the CASE expression in statements such as SELECT. You can use the CASE expression in a clause or statement that allows a valid expression. The CASE expression has two formats: simple CASE and searched CASE. SELECT * FROM Employee WHERE EmpId ) Operator in SQL The SQL CASE expression allows you to evaluate a list of conditions and returns one of the possible results. The following are examples of the above SQL comparison operators. The following are the list of different type of comparison operators available in SQL Server.Ĭonsider X is the variable and the value assigned to X = 5 SQL Operators Comparison operators- (equal), <> (not equal), > (greater than), < (less than), > (greater than or equal to), < (less than or equal to).SQL Comparison operators return true or false based on the comparison. For example, 34 < 35 will return a TRUE value. The SQL server comparison operators are useful to compare one expression with another expression using mathematical operators. When you compare two expressions using the less than or equal to operator(<), the operator returns a TRUE value if the expression on the left side of the operator is less than or equal to the right-side expression.
