SQL statements are case-insensitive, meaning they can be written using lowercase, uppercase or a combination. However, it is customary to write out SQL keywords -- commands or control operators -- in all-caps and table/column names in lowercase. Words in the statement can be treated as case...
The values that are used with the BETWEEN operator are included in the range, meaning that the lower bound includes the value of 10 and the upper bound includes the value of 200. The use of the BETWEEN operator should make your query more easy to read, especially if multiple query conditio...
You can change the meaning of the query by adding parentheses to force evaluation of the OR first. The following query finds only products under models 20 and 21 that are red.SQL Copy SELECT ProductID, ProductModelID FROM Production.Product WHERE (ProductModelID = 20 OR ProductModelID = ...

As media features describe the specific characteristics of a given user agent, output device, or environment, they are range features, meaning you can prefix them with ‘min-’ or ‘max-’ to express the minimum or the maximum condition constraints. ...
The meaning of the code in the expression is, return every customer in the Customers table in the database in the query results. Query expressions return a type that implements IQueryable<T> and IEnumerable<T>, and so they can be iterated using the Seq module as the example shows....
Meaning that the query took 4.5 seconds to execute (and this was only one continuation).To optimize this example query, avoid the use of UPPER in the filter. Instead, when documents are created or updated, the c.description values must be inserted in all uppercase characters. The query ...
We propose in this paper an approach toward a non-navigational query language for object-oriented database systems. This language would be closed under the notions of class and type. We strictly separate these notions and give a set-theoretical meaning to the notion of class. We then describe...
In subject area: Computer Science 'Query Rewriting' refers to the process of finding the maximally contained rewriting for a query given a set of views, where the rewritings are expressed as unions of conjunctive queries. AI generated definition based on: Principles of Data Integration, 2012 ...
