“SELECT” command: The “SELECT” command is used to retrieve data in a database . Syntax for selecting values from the table is as follows: SELECT STUDENT_ID FROM STUDENT; The given query is used to display each student ID from “STUDENT” table. “IN” Clause: The “IN” clause consists of an “IN” operator followed by a set of values. Using an “IN” clause, user can determine whether a column contains one of a particular group of values. Example: The example for “IN” clause is given below: SELECT STUDENT_ID, STUDENT_NAME, STUDENT_CREDIT FROM STUDENT WHERE STUDENT_CREDIT IN(50, 70, 100); The above query is used to list student ID, name, and credit for each student with a credit limit of “50”, “70” or “100”. From the given query, user can determine whether a student credit limit is “50”, “70” or “100” using an “IN” operator.

“SELECT” command:

The “SELECT” command is used to retrieve data in a database.

Syntax for selecting values from the table is as follows:
