Welcome to Mindmajix - The leading global online training platform. There are a lot of opportunities from many reputed companies in the world. This course will help you to achieve excellence in this domain. SQL is a language used to communicate with the server to access, manipulate, and control data. Ans: Alias is a user-defined alternative name given to the column or table. By default column, alias headings appear in upper case.
These statements are mainly used to perform the manipulation activity. It deals with the below operations. This command will take the table name, table column and column values as the input and insert the value in the base table. The table name and values are a mandatory fields, whereas column names are not mandatory if the insert statements have values for all the column of the table. Data Update Data update simply means an update of the value of any column in the table. This statement takes the table name, column name and value as the input and updates the data. If this clause is not given, then the value of the mentioned column in the entire table will be updated.
This does not apply to a BULK or multirow operation. Oracle is transaction oriented; that is, Oracle uses transactions to ensure data integrity. A transaction is a series of SQL data manipulation statements that does a logical unit of work.
I have been told these types of operations are what SQL Server is designed to process and it should be quicker than serial processing. I know cursors exist, but I am not sure how to use them. Can you provide some cursor examples?
