AND is an Operator and we use, when both the conditions are to be true.
LIKE is a condition and we use to combine pattern matching characters. (% refers one or more characters and _ (underscore) refers one character) say, select eName, eId, eRole, eSal from the employees where eSal >= 1000 AND eRole like '%Engineer%' Output (e.g:)
{| |- | eName eId eRole eSal Steve Richard E123 Software Engineer 1060 Janet Mayor E069 Senior Software Engineer 4025 |}

What Is ANSI SQL?
ANSI SQL is the American National Standards Institute standardized Structured Query Language. ANSI SQL is the base for several different SQL languages such as T-SQL and PL/SQL. ANSI SQL is used to Create, Alter, and View data stored within a database. For more information about ANSI: http://www.ansi.org/ For more information about SQL: http://en.wikipedia.org/wiki/SQL

Is A condition statement uses à as its notation?
No, a condition statement does not use "à" as its notation. In programming and logic, condition statements typically use symbols such as "if," "then," or logical operators like "&&" (AND), "||" (OR), and "!" (NOT) to express conditions. The notation "à" is not standard in these contexts.

Where might one go to learn more about SQL IN operators?
One can learn more about the SQL IN operators from the W3Schools website which offers great information and tutorials on many topics related to web design and development. TigZag is quite similar website but offers more advanced knowledge (usually). There is also Beginner SQL Tutorial website and MSDN (the Microsoft Developer Network) website with some advice on these.

Operators are not typically capitalized in programming languages, unless they are part of a language construct or a predefined operator (e.g., "AND" in SQL). It's generally best practice to use operators in lowercase for consistency and readability.
Why do you use Linq over SQL Statements?
The extensibility of the query architecture is used in the LINQ project itself to provide implementations that work over both XML and SQL data. The query operators over XML (LINQ to XML) use an efficient, easy-to-use, in-memory XML facility to provide XPath/XQuery functionality in the host programming language. The query operators over relational data (LINQ to SQL) build on the integration of SQL-based schema definitions into the common language runtime (CLR) type system. This integration provides strong typing over relational data while retaining the expressive power of the relational model and the performance of query evaluation directly in the underlying store.
Can you explain how to use the SELECT statement in SQL to perform mathematical operations on data in a database table?
Yes, in SQL, you can use the SELECT statement along with mathematical operators like , -, , / to perform calculations on data in a database table. For example, you can add, subtract, multiply, or divide values from different columns or apply functions to calculate results. Just include the mathematical operation within the SELECT statement to perform the desired calculation.
How do you use SQL?
You use SQL by issuing commands to an SQL server, either directly by you or by a program you are using.
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 to define a user defined function in SQL?
