Marco de testing metamórfico para consultas SQL con valores nulos [PDF]
, 2020 La falta de información dentro de las bases de datos relacionales expresada mediante valores nulos presenta un problema a la hora de garantizar la calidad de los datos y de las consultas SQL sobre esos datos. Esto ocurre debido a que existen múltiples interpretaciones de los valores nulos y en muchos casos las consultas no consideran que se puedan ...

arXiv, 2019 "PL/SQL functions are slow," is common developer wisdom that derives from the tension between set-oriented SQL evaluation and statement-by-statement PL/SQL interpretation. We pursue the radical approach of compiling PL/SQL away, turning interpreted functions into regular subqueries that can then be efficiently evaluated together with their embracing ...

Achieving Data Privacy through Secrecy Views and Null-Based Virtual Updates [PDF]
IEEE Transaction on Knowledge and Data Engineering, 2013,
25(5):987-1000, 2011 There may be sensitive information in a relational database, and we might want to keep it hidden from a user or group thereof. In this work, sensitive data is characterized as the contents of a set of secrecy views. For a user without permission to access that sensitive data, the database instance he queries is updated to make the contents of the views

Structure Guided Large Language Model for SQL Generation [PDF]
arXivGenerating accurate Structured Querying Language (SQL) is a long-standing problem, especially in matching users' semantic queries with structured databases and then generating structured SQL. Existing models typically input queries and database schemas into the LLM and rely on the LLM to perform semantic-structure matching and generate structured SQL ...

KeyInst: Keyword Instruction for Improving SQL Formulation in Text-to-SQL [PDF]
arXivText-to-SQL parsing involves the translation of natural language queries (NLQs) into their corresponding SQL commands. A principal challenge within this domain is the formulation of SQL queries that are not only syntactically correct but also semantically aligned with the natural language input.
