These operators are compatible with various versions of SQL databases like Parallel Data Warehouse, Azure SQL database, Azure SQL data warehouse, SQL Server 2008, and later versions. Handling missing values is an important task in database management. Comparison operator like equality and inequality ...
Null: Predicates that use theIS NULLoperator test whether values in a given column are NullRange: Range predicates use theBETWEENoperator to test whether one value expression falls between two othersMembership: This type of predicate uses theINoperator to test whether a value is a member of a ...
There are some important rules when using these operators, though. If you're using an operator with values that are non-numeric, you need to put the value in single quotes:'value'. Note:SQL uses single quotes to reference column values. ...
OperatorDescription = (Equal To) For non-null arguments, returns TRUE if the left argument is equal to the right argument; otherwise, FALSE. If either or both arguments evaluate to a null value, the operator returns a null value, unless the comparison 0=null is made, in which case the ...
In Oracle/PLSQL, you can use the<>or!=operators to test for inequality in a query. For example, we could test for inequality using the<>operator, as follows: SELECT * FROM customers WHERE last_name <> 'Anderson'; In this example, the SELECT statement would return all rows from thecus...
Example - Greater Than Operator You can use the>operator in SQL Server to test for an expression greater than. SELECT * FROM employees WHERE employee_id > 3000; In this example, the SELECT statement would return all rows from theemployeestable where theemployee_idis greater than 3000. Anemplo...
Unlike other SQL Server data types, a Boolean data type cannot be specified as the data type of a table column or variable, and cannot be returned in a result set.When SET ANSI_NULLS is ON, an operator that has one or two NULL expressions returns UNKNOWN. When SET ANSI_NULLS is OFF...
TheBETWEENoperator tests if a value is within a specified range. The syntax is as follows: BETWEENminANDmax The presence ofNULLin aBETWEENorNOT BETWEENstatement will result in the statement evaluating toNULL. IS NULLandIS NOT NULLoperators test whether a value is null (undefined). UsingNULLwit...
