No, name is not a reserved word in MySQL, you can use without backtick symbol. If you are working on a reserved word then use backtick symbol. Let us first create a table −mysql> create table name    (    name varchar(10)    ); Query OK, 0 rows affected (0.78 sec)Now you can insert some records in the table using insert command −mysql> insert into name values('John'); Query OK, 1 row affected (0.13 sec) mysql> insert into name values('Carol'); Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −mysql> select *from name;Output+-------+ | name ...

To get the date between dates, you need to use. Here, we are getting the dates between today and today-7 days −select *from yourTableName where DATE(yourColumnName) > (NOW() - INTERVAL 7 DAY);Note : Let’s say the current date is '2019-06-02’ Let us first create a table.mysql> create table DemoTable    (    LoginDate date    ); Query OK, 0 rows affected (0.57 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values('2018-03-21'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable values('2019-05-22'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values('2019-05-27'); ...

For this, use the $all operator. Let us first create a collection with documents −>db.findDocumentExactlySameInArrayDemo.insertOne({"TechnicalSubjects":["C++", "Java", "MongoDB"]}); {    "acknowledged" : true,    "insertedId" : ObjectId("5cd69a5f57806ebf1256f12e") } >db.findDocumentExactlySameInArrayDemo.insertOne({"TechnicalSubjects":["MySQL", "Java", "MongoDB"]}); {    "acknowledged" : true,    "insertedId" : ObjectId("5cd69ac057806ebf1256f12f") } >db.findDocumentExactlySameInArrayDemo.insertOne({"TechnicalSubjects":["C#", "Python", "MongoDB"]}); {    "acknowledged" : true,    "insertedId" : ObjectId("5cd69ad457806ebf1256f130") } >db.findDocumentExactlySameInArrayDemo.insertOne({"TechnicalSubjects":["MySQL", "C", "MongoDB"]}); {    "acknowledged" : true,    "insertedId" : ObjectId("5cd69adf57806ebf1256f131") }Following is the query to display all documents from a collection with the help of find() method −> db.findDocumentExactlySameInArrayDemo.find().pretty();This will produce the following output −{    "_id" : ObjectId("5cd69a5f57806ebf1256f12e"),    "TechnicalSubjects" : [     ...
