SQL-ACT : content-based and history-aware input prediction for non-trivial SQL queries
This thesis presents SqlAct, a SQL auto-completion system that uses content-based and history-aware input prediction to assist in the process of composing non-trivial queries. By offering the most relevant suggestions to complete the partially typed query first at the word-level and then at the …

Structured query language (SQL) related tools
… and secure fashion. Structured Query Language (SQL) is designed to query data contained in a relational database. SQL is important as it is the only way for a user to interact with a relational database. But little focus has been put on SQL because people consider SQL as a simple language. But …

SQL injection detection and exploitation framework for penetration testing
SQL injection is one of the complex and threatening attack used against SQL database servers and web applications. Attackers use SQL injection to get unauthorized access and perform unauthorized data modification. To mitigate the devastating problem of SQL injection attack, there are many existing …

nD-SQL : extending schemaSQL towards multidimensional databases and OLAP
… An n-dimensional query language called nD-SQL is also proposed. This language makes use of the Federation Model and is capable of: (a) resolving schematic discrepancies among a collection of relational databases or data marts with heterogeneous schemas, and (b) supporting a whole range of …

MINCE: Dialect-Aware SQL Decomposition for Federated Query Execution
… enables opportunities for workload optimization, SQL dialect incompatibility makes workload migration difficult. To address this challenge, we develop MINCE (Multi-dialect INtegration and Crossengine Execution), a technique that decomposes SQL queries into parts to enable federated execution …

An Interactive Approach to Generating SQL Queries from Natural Language
… natural-language based interactive interface for SQL query generation. Motivated by a lack of usability of existing systems, nalini was built with the intention of using it for complex query generation. The interface allows users to use a natural language and mathematical operations with a minimal …

Injection of Domain-Specific Knowledge for Enterprise Text-to-SQL
… large language models (LLMs) to solve Text-to-SQL tasks on databases in an enterprise setting. Benchmarks on publicly available datasets do not fully capture the difficulty and complexity of this task in a real-world, enterprise setting. This study examines the critical steps needed to work …

ORM alapú lekérdezés-generálási stratégiák hatása az SQL Server erőforrás-gazdálkodására
… hogy a kliensoldali szűréseket automatikusan SQL-kódra fordítja, arra voltam kíváncsi, hogy milyen rejtett „kényelmi adót” ró a rendszerre nagy adatmennyiség esetén. Ennek feltárására egy több millió rekordos telemetriai adatbázison hasonlítottam össze a paraméterezett LINQ lekérdezéseket a …

Designing a SQL query rewriter to enforce database Row Level Security
This thesis presents the design and implementation of Row Level Security, a fine-grained access control mechanism built on top of a database-agnostic data sharing platform called DataHub. Existing access control mechanisms for database systems are typically coarse-grained, in the sense that users …

Towards A Sufficient Set of Mutation Operators for Structured Query Language (SQL)
… data coverage for database queries written in SQL. An automated tool is also available that mimics real-world faults by mutating SQL, however tests have revealed that these simulated faults do not completely represent real-world faults. This paper demonstrates how half of the mutation operators …
