SQL in Easy Steps (In Easy Steps Series) - Tapa blanda

Sinopsis

SQL (Structured Query Language) is one of the world's most popular languages that help database administrators create, manipulate, update and retrieve information in any major relational database management system. SQL is used both with large databases, such as those running with MySQL servers on a Unix-based platform, and with smaller Intranet databases, such as those running with Microsoft servers on a Windows platform - whatever the server and platform, SQL can communicate with the database. This text shows the reader how to build practical working databases step by step using SQL. It demonstrates each aspect of the SQL language to illustrate how to create tables to store data in a structured format. It also shows how to query the information stored within table records to retrieve data in a wide variety of ways. It covers all esesential features of the SQL language, such as creating databases, tables and records; inserting data; updating and deleting data; retrieving data; grouping and sorting data; calculating fields; data manipulation; joining tables; combining queries; and relational databases.
