14-6 Oracle Fusion Middleware Integrators Guide for Oracle Business Intelligence Enterprise Edition The physical table tag includes the following child elements: CacheExpiry How long table entries should persist in the query cache. A value of 0 indicates that cache entries do not expire. isCacheEventTable If set to true, indicates that this table has been registered as an Oracle BI Server event polling table. isOverrideCacheProp For alias tables only. If set to true, indicates that the alias table has its own cache properties that override the cache properties of the source table. pollFreq The polling frequency, in seconds. Only applies if this table is an Oracle BI Server event polling table. The default value is 3600 seconds. x The x coordinate of the table when it is shown in the physical diagram. y The y coordinate of the table when it is shown in the physical diagram. rowCount The latest number of rows retrieved for this physical table. lastUpdated The time at which row counts were last updated for this physical table. uri For XML data sources only. The resource identifier for the XML data source. xslPath For XML data sources only. An XSLT file contains formatting rules written according to the XSLT standard. It defines how an XML file may be transformed. maxConn For XML data sources only. The maximum number of connections allowed to the same URL from different users. xmlRefreshInterval For XML data sources only. The time interval after which the XML data source is queried again directly, rather than using results in cache. scriptPath For XML data sources only. The extended gateway script path. hints For Oracle Databases only. Lists any database hints, such as index hints or leading hints, that were specified for this physical table. isExtGatewayInProcess For XML data sources only. Indicates that this physical table is the extended gateway part of the process. extGatewayDelimiter For XML data sources only. The row delimiter used in the metadata import process, typically the second level element in the XML document. isSysGen If set to true, indicates that an internal utility has generated this physical table. isDDLAggr Indicates whether this physical table is an aggregate table. isDeployedView For relational databases only. If set to true, indicates that this physical table is a deployed opaque view. An opaque view is a Physical layer table that consists of a SELECT statement. Table 14–6 Cont.

References the physical table that is being used as the source for this alias table. The physical table is contained in a sub-element called RefPhysicalTable. DBMap Stores the value of database-specific strings. The DBMap element contains an Item tag, which in turn contains a Value tag, as follows: Item name= Value Item AggrConnPool If this physical table is an aggregate table, this element references the connection pool used for the aggregate. The connection pool is contained in a sub-element called RefConnectionPool. RefVariable If a session variable is being used to specify the name of this physical table, this element references that session variable. MemberKey Applies to parent-child relationship tables that support parent-child hierarchies on relational sources. The name of the column that uniquely identifies members of the parent-child relationship table. ParentKey The name of the column that contains the key of the parent or ancestor member. Applies to parent-child relationship tables that support parent-child hierarchies on relational sources. DistanceColumn The name of the column that records the number of levels between the member and the ancestor. Applies to parent-child relationship tables that support parent-child hierarchies on relational sources. LeafColumn The name of the column that indicates whether the member has no child members 1 if the member is a leaf and has no children, 0 if the member is not a leaf and has children. Applies to parent-child relationship tables that support parent-child hierarchies on relational sources. XSLT This child element is reserved for a future release. XSDSchema This child element is reserved for a future release. 14-8 Oracle Fusion Middleware Integrators Guide for Oracle Business Intelligence Enterprise Edition hints= isExtGatewayInProcess= extGatewayDelimiter= isSysGen= isDDLAggr= isDeployedView= SourceTable RefPhysicalTable … SourceTable DBMap Item name= Value … Item DBMap AggrConnPool RefConnectionPool … AggrConnPool RefVariable … PhysicalTable Example PhysicalTable name=Product parentName=quot;Paintquot;..quot;quot; parentId=3023:205 id=3001:601 uid=656 type=none x=191 y=436 rowCount=91.0 lastUpdated=2000-08-14 09:12:14 uri=VALUEOFBI_EE_HOMEserverSamplepaintProduct.xml maxConn=0 extName=Product Description PhysicalTable

14.6 Physical Column

The physical column element corresponds to the physical column object in the Physical layer. The physical column tag includes the following attributes: Table 14–8 Physical Column Tag Attributes Attribute Name Description extName The external name for the physical column. This attribute is required if the same name such as STATE is used in multiple hierarchies. This attribute is optional for XML documents. For XML, the extName attribute stores the fully qualified name of a column. dataType The data type of the physical column, such as VARCHAR. This option is called Type in the Physical Column dialog in the Administration Tool. nullable If set to true, indicates that null values are allowed for the column. This allows null values to be returned to the user, which is expected with certain functions and with outer joins.
