Query by Example (QBE) is a database query language for relational databases. A QBE parser parses the search query and looks for the keywords. A more formal query string, in languages such as SQL, is then generated, which is finally executed. However, when compared with a formal query, the results in the QBE system will be more variable.
SQL (Structured Query Language) SQL is a set-based, declarative query language, not an imperative language such as C or BASIC. However, there are extensions to Standard SQL which add procedural programming language functionality, such as control-of-flow constructs
A data Sublanguage is a computer language used to define or manipulate the structure of a relational database management system(DBMS) e.g QBE, SQL.

Connect to a SQL Server, query with Transact-SQL (T-SQL), and view the results with the mssql plugin for Visual Studio Code. The SQL Database projects extension for VS Code comes with the mssql extension, which supports SQL projects on Windows, macOS, and Linux. To learn more about data science please visit- Learnbay.co
Script is a term used to describe programs that aren't compiled (that is, turned into 1's and 0's) first. A scripting engine reads the code exactly how you wrote it, and turns it into a computer program on the fly. Query is just a fancy word for question, but on the web it generally means "SQL Query." An SQL query is a way of asking a database for information, that follows the Structured Query Language syntax. All SQLs are a bit off of the actual SQL standard, and you have to work with whatever version your relational database (RD) supports.
gand maro...is the answer
QBE is an advantage over SQL as it is a visual technique allowing non-experts to do searches, as it is simple to understand.
It is harder to set up than SQL
QBE (or query-by-example) is often a quick method of creating simple SQL queries, especially by users who are not particularly SQL-savvy. Instead of having to remember specific SQL syntax, the user builds the query by selecting tables and fields from a display and entering WHERE and GROUP BY clause specifics in a fill-in-the-box manner.
T-SQL is Microsoft's version of the generic SQL langauge to be used with, for example, Microsoft SQL Server.
one of the difference is HQL does not support distinct but SQL supports the distinct in the query

sql exception which provides information on database access errors where as sql warning provides inforamation on database access warnings.
Pervasive SQL is a relational database management system designed for embedded applications, while MS SQL, or Microsoft SQL Server, is a full-fledged RDBMS with advanced features for enterprise applications. MS SQL provides more robust scalability, security, and integration options compared to Pervasive SQL. Additionally, MS SQL is commonly used in larger organizations, while Pervasive SQL is often utilized in smaller businesses and embedded systems.
