The SQL From clause is the source of a rowset to be operated upon in a Data Manipulation Language Data Manipulation Language DML statement. From clauses are very common, and will provide the rowset to be exposed through a Select SQL Select statement, the source of values in an Update SQL Update statement, and the target rows to be deleted in a Delete SQL Delete statement. code FROM code is an SQL reserved word in the SQL 2003 SQL standard The code FROM code clause is used in conjunction with SQL statements, and takes the following general form SQL DML Statement FROM table name WHERE predicate The From clause can generally be anything that returns a rowset, a table, view, function, or system provided information like the Information Schema , which is typically running proprietary commands and returning the information in a table form. ref cite web url http www.sqlteam.com article the from clause title The FROM Clause author Bill Graziano date 24 June 2002 ref Examples The following query returns only those rows from table mytable where the value in column mycol is greater than 100. source lang sql SELECT FROM mytable WHERE mycol 100 source Requirement The From clause is technically required in relational algebra and in most scenarios to be useful.

XML for Analysis abbreviated as XMLA is an industry standard for data access in analytical systems, such as OLAP and data mining . XMLA is based on other industry standards such as XML , SOAP and HTTP . XMLA is maintained by XMLA Council with Microsoft , Hyperion Solutions Corporation Hyperion and SAS Institute SAS being the official XMLA Council founder members. ref cite web title What is XMLA? url http www.xmlforanalysis.com index.htm ref History The XMLA specification was first proposed by Microsoft as a successor for OLE DB for OLAP in April 2000. By January 2001 it was joined by Hyperion Solutions Corporation Hyperion endorsing XMLA. The 1.0 version of the standard was released in April 2001, and in September 2001 the XMLA Council was formed. In April 2002 SAS Institute SAS joined Microsoft and Hyperion as founding member of XMLA Council. ref cite web title XML for Analysis gathers steam url http www.olapreport.com Comment APIs.htm ref With time, more than 25 companies joined with their support for the standard. API XMLA consists of only two SOAP methods. ref cite web title XML for Analysis Specification url http msdn.microsoft.com en us library ms977626.aspx ref It was designed in such a way to preserve simplicity.

Properties XML list of command properties such as Timeout, Catalog name, etc. The result of Execute command could be Multidimensional Dataset or Tabular Rowset . Discover Discover method was designed to model all the discovery methods possible in OLEDB including various schema rowset, properties, keywords, etc. Discover method allows users to specify both what needs to be discovered and the possible restrictions or properties. The result of Discover method is a rowset. Query language XMLA specifies MDXML as the query language. In the XMLA 1.1 version, the only construct in MDXML i ... more details
Multiple issues unreferenced December 2009 cleanup March 2008 context October 2009 Meta SQL Use with reference to PeopleSoft Meta SQL expands to platform specific SQL substrings, causes another function to be called, or substitutes a value. Meta SQL constructs are used in functions that pass SQL strings, such as the following SQLExec. Scroll buffer functions ScrollSelect and its relatives . PeopleSoft Application Designer dynamic and SQL views. Some Rowset class methods Select, SelectNew, Fill, and so on. . The SQL class. PeopleSoft Application Engine programs. Some Record class methods Insert, Update, and so on. . COBOL functions. Meta SQL Element Types There are three types of meta SQL elements Constructs are a direct substitution of a value, and help to build or modify a SQL statement. Examples include Bind, InsertSelect, and List. Functions perform actions or cause another function to be called. Examples include ClearCursor, Execute, and ExecuteEdits. Meta variables enable substitution of text within SQL statements. Examples include AsOfDate, Comma, and JobInstance. Meta SQL Placement Considerations Not all meta SQL can be used by all programs. Some meta SQL can be used only in Application Engine programs. Other meta SQL can only be used as part of a SQL statement in a SQL or dynamic view. The following table lists available meta SQL elements and where each element can be used. If a meta SQL construct, function, or meta variable is supported in PeopleCode, it is supported in all types of PeopleCode programs that is, in Application Engine PeopleCode programs actions , component interface PeopleCode programs, and so on. Note Even if a meta SQL element is used in PeopleCode, you cannot use meta SQL like a built in function. You can use meta SQL in the SQLExec function, the Select method, the Fill method, and so on. Note Meta SQL is not available in SQR DEFAULTSORT Meta Sql Category SQL ... more details
