Syntax\n------\n\nexpr IN (value,...)\n\nDescription\n-----------\n\nReturns 1 if _expr_ is equal to any of the values in the IN list, else returns 0. If all values are constants, they are evaluated according to the type of _expr_ and sorted. The search for the item then is done\\\nusing a binary search. This means IN is very quick if the IN value list consists entirely of constants. Otherwise, type conversion takes place according to the rules described at Type Conversion, but\\\napplied to all the arguments.\n\nIf _expr_ is NULL, IN always returns NULL. If at least one of the values in the list is NULL, and one of the comparisons is true, the result is 1. If at least one of the values in the list is NULL and none of the comparisons is true, the result is NULL.\n\nExamples\n--------\n\nSELECT 2 IN (0,3,5,7);\n+----------------+\n| 2 IN (0,3,5,7) |\n+----------------+\n|              0 |\n+----------------+\n\nURL: https://mariadb.com/docs/server/reference/sql-structure/operators/comparison-operators/in
