# Logical Operators (Transact-SQL)
[!INCLUDE [SQL Server Azure SQL Managed Instance](../../includes/applies-to-version/sql-asdbmi.md)]

  Logical operators test for the truth of some condition. Logical operators, like comparison operators, return a **Boolean** data type with a value of TRUE, FALSE, or UNKNOWN.  
  
|Operator|Meaning|  
|--------------|-------------|  
|[ALL](../../t-sql/language-elements/all-transact-sql.md)|TRUE if all of a set of comparisons are TRUE.|  
|[AND](../../t-sql/language-elements/and-transact-sql.md)|TRUE if both Boolean expressions are TRUE.|  
|[ANY](../../t-sql/language-elements/any-transact-sql.md)|TRUE if any one of a set of comparisons are TRUE.|  
|[BETWEEN](../../t-sql/language-elements/between-transact-sql.md)|TRUE if the operand is within a range.|  
|[EXISTS](../../t-sql/language-elements/exists-transact-sql.md)|TRUE if a subquery contains any rows.|  
|[IN](../../t-sql/language-elements/in-transact-sql.md)|TRUE if the operand is equal to one of a list of expressions.|  
|[LIKE](../../t-sql/language-elements/like-transact-sql.md)|TRUE if the operand matches a pattern.|  
|[NOT](../../t-sql/language-elements/not-transact-sql.md)|Reverses the value of any other Boolean operator.|  
|[OR](../../t-sql/language-elements/or-transact-sql.md)|TRUE if either Boolean expression is TRUE.|  
|[SOME](../../t-sql/language-elements/some-any-transact-sql.md)|TRUE if some of a set of comparisons are TRUE.|
