Using NOT IN constraint with the update query The output of the execution of the above query statement is as follows, containing the records of the table educba_writers for which the column of rate does not have the value of 650 or 750 in it – SELECT * FROM `educba_writers` WHERE rate NOT IN (650,700) Our query statement will be as shown below. Let us consider one example using the above tables and retrieve the records of the table educba_writers not having rate 650 or 700 as the column value of rate column using the NOT IN clause in the SELECT query statement. Using NOT IN constraint with the select query We will see examples of each of the DML statements one by one.

Now, we are ready to use the NOT IN constraint on the above tables.

Let us retrieve the contents of both tables.Įxecuting the select query mentioned below for the educba_learning table gives the following output –Įxecuting the select query for educba_writers table gives the following output – INSERT INTO `educba_writers` (`id`, `firstName`, `rate`, `joining_date_time`) VALUESĪs you can see, we have inserted some records in both the tables. INSERT INTO `educba_learning` (`topic_id`, `subject`, `sessions`, `expert_name`, `charges`) VALUES Now, we will insert some records in both of the tables – The execution of the above query statement will give the following output – `joining_date_time` DATETIME DEFAULT NULL Let us create two tables named educba_learning and educba_writers using the following create table statements. We will study the working of NOT IN constraint by using it in different DML statements of SQL such as SELECT, INSERT, UPDATE and DELETE. We will learn how we can implement the NOT IN statement inside the queries operating on tables and involving fetching, updation, insertion, and removal of the records one by one using examples.

The expressions mentioned inside the parameters of the NOT IN clause can be the literal values, variables, names of the columns of other tables, or an all different subquery resulting in the records containing the values to be excluded for the column named column_name in the query. The column_name in the syntax is the name of the column of the table on which the query is being applied for which we have to specify the condition that the value of the column should not contain the expression values mentioned in the list containing comma-separated expression that evaluates to values that need to be excluded for column value. We can use the above syntax in the WHERE clause while using any of the DML statements of SQL such as SELECT, UPDATE, INSERT, and DELETE.
