Difference between = and IN Operator
= Operator | IN Operator |
---|---|
It allows comparison of attributes with single value. | It allows comparison of attributes with multiple value. For single value comparison behaves same as = . |
For multiple comparison we have to use appropriate Operator in addition.(i.e JOIN, OR, AND, etc.) | No additional use of Operator required. |
Useful in scenarios when sub-query returns single value as result. | Useful in scenarios when sub-query returns multiple values as result. |
It will generate an error if you have more than one result on the subquery. | It will not generate an error if you have multiple results on the subquery. |
It is faster as compared to IN Operator. | The IN clause is slower compared to = as it compares with multiple values until the condition satisfies. |
