Technique #1: How to find duplicate values in SQL table Identifyingduplicate valuesin a database is essential for maintaining data integrity and accuracy. To find duplicate values in an SQL table, you can utilize the “GROUP BY” and “HAVING” clauses along with aggregate functions. ...
SQL is a standardized language used to access and manipulate databases to build customizable data views for each user. SQL queries are used to execute commands, such as data retrieval, updates, and record removal. Different SQL elements implement these tasks, e.g., queries using the SELECT stat...
Prepared statements (parameterized queries) can be used to execute the same or similar SQL statements repeatedly, often with high efficiency. Instead of assembling a query string, preparestatement can be a good defence against SQL injection, because parameter values (transmitted later using a ...
Since many websites sanitize against direct user input, hackers will inject SQL that’s designed to execute only on subsequent visits. With basic input-sanitization countermeasures in place, the target website would block a normal SQLI attack — otherwise known as a “first-order” attack. But ...

Structured Query Language (SQL) is a standardized programming language that is used to managerelational databasesand perform various operations on the data in them. Initially created in the 1970s, SQL is regularly used not only by database administrators but also by developers writing data integratio...
Scalability.NoSQL databases usually execute horizontal scaling, also known as scaling out. Scaling out involves adding more hardware to a system, usually in the form of new commodity servers. Horizontal partitioning using sharding is frequently used in NoSQL systems to break large databases into smal...
In addition, scalability also increases. Parallel Execution Plans for DirectQuery This improvement enables the Analysis Services engine to analyze DAX queries against a DirectQuery data source and identify independent storage engine operations. The engine can then execute those operations against the data ...

Remember, databases will happily execute multiple SQL statements in a row if separated by a semicolon. Failure to sanitize the user input for the single quote “‘” character makes it possible for an attacker to delete the entire table. Hope you had good backups. Right? Right…?...
