Using Oracle XML DB1. This chapter provides an overview of how to use Oracle XML DB. The examples here illustrate techniques for accessing and managing XML content in purchase orders. The format and data of XML purchase orders are well suited for Oracle XML DB storage and processing techniques because purchase orders are highly structured XML documents. However, the majority of techniques introduced here can also be used to manage other types of XML documents, such as those containing unstructured or semi structured data. This chapter also further explains Oracle XML DB concepts introduced in Chapter 1, Introduction to Oracle XML DB. This chapter contains these topics Storing XML as XMLType. Before the introduction of Oracle XML DB, there were two ways to store XML content in Oracle Database Use Oracle XML Developers Kit XDK to parse the XML document outside Oracle Database, and store the extracted XML data as rows in one or more tables in the database. Store the XML document in Oracle Database using a Character Large Object CLOB, Binary Large Object BLOB, Binary File BFILE, or VARCHAR column. In both cases, Oracle Database is unaware that it is managing XML content. The introduction of Oracle XML DB and the XMLType data type provides new techniques that facilitate the persistence of XML content in the database.

Connect with us for savings, support satisfactionThese techniques include the ability to store XML documents in an XMLType column or table, or in Oracle XML DB Repository. Storing XML as an XMLType column or table makes Oracle Database aware that the content is XML. This lets the database Perform XML specific validations, operations, and optimizations on the XML content.

Facilitate highly efficient processing of XML content by Oracle XML DBWhat is XMLType Oracle. XMLType, to facilitate native handling of XML data in the database XMLType can represent an XML document in the database, so it is accessible in SQL. XMLType has built in methods that operate on XML content. For example, you can use XMLType methods to create, extract, and index XML data stored in Oracle Database. XMLType functionality is also available through a set of Application Program Interfaces APIs provided in PLSQL and Java. XMLType can be used in PLSQL stored procedures for parameters, return values, and variables. With XMLType, SQL developers can leverage the power of the relational database while working in the context of XML. XML developers can leverage the power of XML standards while working in the context of a relational database. XMLType can be used as the data type of columns in tables and views. XMLType variables can be used in PLSQL stored procedures as parameters and return values. You can also use XMLType in SQL, PLSQL, C, Java through JDBC, and Oracle Data Provider for. NET ODP. NET. The XMLType API provides a number of useful methods that operate on XML content. For example, method extract extracts one or more nodes from an XMLType instance.

A. Oracle Technology Network provides services and resources to help developers, DBAs, and architects build, deploy, manage, and optimize applications using Oracle. Many of these XMLType methods are also provided as SQL functions. For example, SQL function extract corresponds to XMLType method extract. Oracle XML DB functionality is based on the Oracle XML Developers Kit C implementations of the relevant XML standards such as XML Parser, XML DOM, and XML Schema Validator. Benefits of XMLType Data Type and APIThe XMLType data type and application programming interface API enable SQL operations on XML content and XML operations on SQL content Versatile API XMLType has a versatile API for application development that includes built in functions, indexing, and navigation support. XMLType and SQL You can use XMLType in SQL statements, combined with other data types. For example, you can query XMLType columns and join the result of the extraction with a relational column. Oracle Database determines an optimal way to run such queries. Indexing You can created several kinds of indexes to improve the performance of queries on XML data. For structured storage of XMLType data, you can create B tree indexes on the object relational tables that underlie XMLType tables and columns. For unstructured and binary XML storage of XMLType data, you can create an XMLIndex index, which specifically targets the XML structure of a document.

This applies to all XMLType storage models. You can index the textual content of XML data with an Oracle Text CONTEXT index, for use in full text search. This applies to all XMLType storage models. When to Use XMLType. Use XMLType whenever you want to use the database as a persistent storage of XML data. XMLType features include the following SQL queries on part of or the whole XML document SQL functions exists. Node and extract provide the necessary SQL query functions over XML documents. XPath access using SQL functionsexists. NodeandextractXMLType uses the built in C XML parser and processor and hence provides better performance and scalability when used inside the server. Strong typing inside SQL statements and PLSQL functions The strong typing offered by XMLType ensures that the values passed in are XML values and not any arbitrary text string. Indexing on XPath document queries XMLType has methods that you can use to create function based indexes that optimize searches. Cash Receipt Format Free Download. Separation of applications from storage models Using XMLType instead of directly using CLOB, object relational, or binary XML storage lets applications gracefully move to various storage alternatives later without affecting any of the query or DML statements in the application. Support for future optimizations New XML functionality will support XMLType. Because Oracle Database is natively aware that XMLType can store XML data, better optimizations and indexing techniques can be done. By writing applications to use XMLType, these optimizations and enhancements can be easily achieved and preserved in future releases without your needing to rewrite applications. Creating XMLType Tables and Columns. The following examples create XMLType columns and tables for managing XML content in Oracle Database. Example 3 1 Creating a Table with an XMLType Column. CREATE TABLE mytable. VARCHAR21. 0 PRIMARY KEY, xmlcolumn XMLType. Example 3 2 Creating a Table of XMLType. CREATE TABLE mytable. OF XMLType. Using Virtual Columns to Constrain Data Stored as Binary XMLXML data has its own structure, which, except for object relational storage of XMLType, is not reflected directly in database structure. That is, individual XML elements and attributes are not mapped to individual database columns or tables. This means that, to constrain XML data according to the values of individual elements or attributes, the standard approach for relational data does not apply. Instead, you must create virtual columns that represent the XML data of interest, and then use those virtual columns to define the constraints that you need. This approach applies only to XML data that is stored as binary XML. For XML data that uses unstructured storage, the database has no knowledge of the XML structure the data is treated as flat text, but for binary XML storage that structure is known. You exploit this structural knowledge to create virtual columns, which the database can then use with constraints. The technique is as follows Define virtual columns that correspond to the XML data that you are interested in. Use those columns to constrain the XMLType data as a whole.
