19、otechni- cal Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of techn

20、ical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. International Standards are drafted in accordance with the rules given in the ISOLE

21、C Directives, Part 3. In the field of information technology, IS0 and IEC have established a joint technical committee, ISOIEC JTC 1. Draft International Standards adopted by the joint technical committee are circu- lated to national bodies for voting. Publication as an International Standard requir

22、es approval by at least 75% of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this Amendment may be the subject of patent rights. IS0 and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 1 to parts 1, 2

23、 and 5 of ISOIEC 9075:1999 was prepared by Joint Technical Committee ISOIEC JTC 1, Information technology, Subcommittee SC 32, Data management and interchange.

24、endment is as follows: Clause 1, “Scope”, specifies the scope of this Amendment. Clause 2, “Normative references”, identifies additional standards that, through reference in this Amendment, constitute provisions of this Amendment. Clause 3, “Definitions, notations, and conventions”, defines the nota

25、tions and conventions used in this Amendment. Clause 4, “Concepts”, presents concepts used in the definition of On-Line Analytical Processing facilities. Clause 5, “Lexical elements”, defines a number of lexical elements used in the definition of On-Line Analytical Processing facilities. Clause 6, “

26、Scalar expressions”, defines a number of scalar expressions used in the definition of On-Line Analytical Processing facilities. Clause 7, “Query expressions”, defines the elements of the language that produce rows and tables of data as used in On-Line Analytical Processing facilities. Clause 8, “Add

27、itional common elements”, defines additional common elements used in the definition of On-Line Analytical Processing facilities. Clause 9, “Schema definition and manipulation”, defines the schema definition and manipulation statements associated with the definition of On-Line Analytical Processing f

28、acilities. Clause 10, “SQL-client modules”, defines SQL-client modules and externally-invoked procedures. Clause 11, “Data manipulation”, defines data manipulation operations associated with On-Line Analytical Processing facilities. Clause 12, “Dynamic SQL”, defines the SQL dynamic statements. Claus

29、e 13, “Information Schema”, defines viewed tables that contain schema information related to On-Line Analytical Processing facilities. Clause 14, “Status codes”, defines SQLSTATE values related to On-Line Analytical Processing facilities. Clause 15, “Conformance”, defines the criteria for conformanc

30、e to this Amendment. Annex A, “SQL conformance summary”, is an informative Annex. It summarizes the confor- mance requirements of the SQL language. Annex B, “Implementation-defined elements”, is an informative Annex. It lists those features for which the body of this Amendment states that the syntax

31、, the meaning, the returned results, the effect on SQL-data andor Schemas, or any other behavior is partly or wholly implementation-defined. viii On-Line Analytical Processing (SQUOLAP) O ISOAEC 2001 - All rights reserved ISO/IEC 9075 (parts 1, 2 and 5):1999/Amd.l:2001 (E) Annex C, “Implementation-d

32、ependent elements”, is an informative Annex. It lists those features for which the body of this Amendment states that the syntax, the meaning, the returned results, the effect on SQL-data andor Schemas, or any other behavior is partly or wholly implementation-dependent. Annex D, “SQL feature and pac

33、kage taxonomy”, is an informative Annex. It identifies features of the SQL language specified in this Amendment by a numeric identifier and a short descriptive name. This taxonomy is used to specify conformance to Core SQL and may be used to develop other profiles involving the SQL language. Annex E

34、, “SQL Packages”, is an informative Annex. It specifies a package of SQL language features. In the text of this Amendment, Clauses begin a new odd-numbered page, and in Clause 5, “Lexical elements”, through Clause 15, “Conformance”, Subclauses begin a new page.
