Final answer:
In a no equijoin, the operators used are >=, <=, or BETWEEN ...AND, which are used to join tables based on criteria other than equality, such as ranges or inequalities.
Step-by-step explanation:
The operator typically used in a nonequijoin is A. >=, <=, or BETWEEN ...AND. A nonequijoin is a type of join where the join condition is based on something other than equality. Instead of finding rows with matching values, the condition that combines rows from different tables involves inequality operators such as greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), or a range using BETWEEN ... AND. These types of joins are useful when you need to combine records that fall within a certain range or satisfy a particular inequality condition rather than a specific matching value.
