how to use the SQL Server ALL operator to compare a value with a list of single column set of values.
Shathana. S.R. Answered question May 27, 2023
The SQL Server ALL operator is a logical operator that compares a scalar value with a single-column list of values returned by a subquery.
- The
subquerywithin the parentheses is a Selectstatement that returns a result of a single column. - Also, the data type of the returned column must be the same data type as the data type of the scalar expression.
The ALL operator returns TRUE if all the pairs (scalar_expression, v) evaluates to TRUE; v is a value in the single-column result.
If one of the pairs (scalar_expression, v) returns FALSE, then the ALL operator returns FALSE.
