SQL DELETE Statement

The DELETE statement is used to delete records in a table.

The DELETE Statement

The DELETE statement is used to delete rows in a table.

SQL DELETE Syntax

Note: Notice the WHERE clause in the DELETE syntax. The WHERE clause specifies which record or records that should be deleted. If you omit the WHERE clause, all records will be deleted!

SQL DELETE Example

The "Persons" table:

Now we want to delete the person "Tjessem, Jakob" in the "Persons" table.

We use the following SQL statement:

imageThe "Persons" table will now look like this:

Delete All Rows

It is possible to delete all rows in a table without deleting the table. This means that the table structure, attributes, and indexes will be intact:

Note: Be very careful when deleting records. You cannot undo this statement!

XML Document Schema

XML Document Schema Databases have schemas, which are used to constrain what information can be stored in the database and to constrain the data types of the stored information. In contrast, by default, XML documents can be created without any associated schema: An el- ement may then have any subelement or attribute. While such freedom may occasionally be acceptable given the self-describing nature of the data format, it is not generally useful when XML documents must be processesed automatically as part of an application, or even when large amounts of related data are to be formatted in XML. Here, we describe the document-oriented schema mechanism included as part of the XML standard, the Document Type Definition , as well as the more recently defined XML S chema . Document Type Definition The document type definition ( D TD ) is an optional part of an XML document. The main purpose of a DTD is much like that of a schema: to constrain and type the information present in the docume

Extended Relational-Algebra Operations.

Extended Relational-Algebra Operations The basic relational-algebra operations have been extended in several ways. A simple extension is to allow arithmetic operations as part of projection. An important extension is to allow aggregate operations such as computing the sum of the elements of a set, or their average. Another important extension is the outer-join operation, which allows relational-algebra expressions to deal with null values, which model missing information. Generalized Projection The generalized-projectio n operation extends the projection operation by allowing arithmetic functions to be used in the projection list. The generalized projection operation has the form where E is any relational-algebra expression, and each of F 1 , F 2 ,.. . , F n is an arithmetic expression involving constants and attributes in the schema of E . As a special case, the arithmetic expression may be simply an attribute or a constant. For example, suppose we have a relation c r

Distributed Databases:Concurrency Control in Distributed Databases

Concurrency Control in Distributed Databases We show here how some of the concurrency-control schemes discussed in Chapter 16 can be modified so that they can be used in a distributed environment. We assume that each site participates in the execution of a commit protocol to ensure global trans- action atomicity. The protocols we describe in this section require updates to be done on all replicas of a data item. If any site containing a replica of a data item has failed, updates to the data item cannot be processed. In Section 19.6 we describe protocols that can continue transaction processing even if some sites or links have failed, thereby providing high availability. Locking Protocols The various locking protocols described in Chapter 16 can be used in a distributed environment. The only change that needs to be incorporated is in the way the lock manager deals with replicated data. We present several possible schemes that are applicable to an environment where data can be rep
