What are the main function in sql?
SQL (Structured Query Language) is a language used in a SQL server to manage data (Query the data, insert, Update, Delete) as well as perform data manipulation (calculations, etc)
What is the difference between SQL and SQLPlus?
Structured Query Language, abbreviated as SQL, is a programming language. It is designed to manage data stored in relational databases. Various commands or operations like Select, Group by, Insert, Modify, etc, are implemented using SQL to fetch, retrieve or add data to the database. It can be used in correlation with other programming languages like Python or Java, to build applications. Any tool or application can communicate with the Oracle server using the command language SQL. Oracle SQL has numerous extensions. A SQL statement that you enter is saved in memory's "SQL buffer" and stays there until you write another SQL statement. An Oracle tool called SQLPlus identifies and sends SQL statements to the Oracle9i Server for execution. It has a built-in command language. It is a client program allowing users to enter SQL and PL/SQL commands and execute them. SQLPlus comes with the Oracle installation. It is commonly used to develop and run SQL and PL/SQL statements, scripts, and reports. SQL SQLPLus is a language used to access data from the Oracle server by talking with it. Recognizes SQL statements and sends them to the server Is based on American National Standards Institute (ANSI)-standard SQL Is Oracle's interface for running SQL statements proprietary? manipulates the database's data and table definitions. does not permit changing of database values employs a termination character to carry out directives right away. does not need termination characters and immediately carries out commands. Uses functions to perform some formatting Uses commands to format data
Compare the use of embedded SQL with the use in SQL of functions defined in a general-purpose of Programming language Under what circumstances would you use each of these features?
SQL functions are primarily a mechanism for extending the power of SQL to handle attributes of complex data types (like images), or to perform complex and non-standard operations. Embedded SQL is useful when imperative actions like displaying results and interacting with the user are needed. These cannot be done conveniently in an SQL only environment. Embedded SQL can be used instead of SQL functions by retrieving data and then performing the function's operations on the SQL result. However a drawback is that a lot of query-evaluation functionality may end up getting repeated in the host language code Regards, Jose Deleep. S
How many type of SQL?
There are three types of SQL: 1. Cognos SQL 2. Native SQL 3. Pass-through SQL Cognos SQL Framework Manager generates Cognos SQL in a more efficient manner in order to keep its functionality. It is common for Cognos SQL to be translated into Native SQL before being transmitted to the database for processing. Some actions or functions may not be supported by the database in some instances. Only a portion of the Cognos SQL is transmitted to the database in these situations. As a result, the database handles part of the query and the Cognos server handles the rest. Advantages: Has the ability to include metadata from many sources. Reduce the number of database constraints Interact more effectively with Cognos applications. Disadvantages: You cannot use non standard SQL. Native SQL Databases such as Oracle, SQL Server, and DB2 all support SQL. Using Native SQL in a model query subject with many data sources is not possible. Advantages: All relevant query subjects are optimized for performance. You can utilize SQL that is specific to the database you are using. Disadvantages: You cannot use SQL that the data source does not support for sub queries. The query subject may not be compatible with different database types. Pass-through SQL Allows the usage of Native SQL without regard to the limitations imposed on subqueries by the data source. Subqueries are not processed in Pass-Through SQL query subjects. It is instead supplied directly to the data source that generates query results for each subject. It is important to keep in mind that pass-through SQL is delivered straight to the data source rather than being optimized by the Framework Manager, therefore performance will be lower than with the other query options. Using curly brackets around your SQL statement in a Tabular SQL object causes that SQL statement to be passed through to the database. Cognos has not validated this SQL, so take that into consideration. Step1: Create a Tabular SQL object. Write a statement surrounded with { }. Actual: SELECT * FROM ORDER HEADER Pass-Through: {SELECT * FROM ORDER HEADER} Advantages: You can use any SQL supported by the database. Disadvantages: Framework manager does not have the ability to automatically optimize performance. In some cases, the SQL won't function with another data source.

Which SQL statement is used to update data in a database?
The SQL statement used to update data in a database is the "UPDATE" statement.
