PostgreSQL - 21 | Usage of PostgreSQL ALL_OPERATOR & SOME_OPERATOR
Hello Friends, In this Video we learn about "Usage of PostgreSQL ALL_OPERATOR & SOME_OPERATOR".
This video describes the usage of "ALL" and "SOME" operators that are used for set comparisons in SQL queries.
"ALL" Operator: Compares a value to every value returned by a subquery, returning true if the comparison holds true for all values.
"SOME" Operator: Compares a value to at least one value returned by a subquery, returning true if the comparison holds true for at least one value.
Both operators are handy when you need to compare a single value against multiple values from a subquery, offering flexibility and efficiency in SQL queries.
Also, it is important to note that the most crucial things are sorted when you start practicing on your end. So, keep learning :)
Thank you so much for watching our video, if you need any type of help then you can contact us.
