What is SQL and how does it work?
SQL is used to communicate with a database. According to ANSI (American National Standards Institute), it is the standard language for relational database management systems. SQL statements are used to perform tasks such as update data on a database, or retrieve data from a database.
What is data in SQL with example?
In SQL, each column (in a table) has a data type. This restricts the type of data that can be stored in a column. For example, if the data type of a column is INTEGER, we can only store integer values such as 0, 1, -1 etc. in that column.
What is SQL and its data types?
SQL Data Type is an attribute that specifies the type of data of any object. Each column, variable and expression has a related data type in SQL. You can use these data types while creating your tables. You can choose a data type for a table column based on your requirement.
