USMeta.Sets

Previous Next

At runtime, gets metadata information about sets from the model developed in USoft Definer. For each retrieved set, this information takes the form of name/value pairs. Each name/value pair expresses an attribute setting for the set. Information about set elements is also included.

Returns an XML document of the form demonstrated in the Example below.

Syntax

SELECT USMeta.Sets(
       set-name-pattern     Sets
,      interfaces-only      InterfacesOnly

,      module-pattern       Module
)

 

interfaces-only    ::=      { yes | no }

All parameters are optional. Parameter values that you pass are mapped to parameters by alias name. The '.*application.*' value in the following example is for set-name-pattern because of the "Sets" alias:

SELECT USMeta.Sets( '.*application.*' Sets )

Set-name-pattern is a regular expression that matches zero, one or more set names in the model. The result data is limited to sets matching the pattern. If set-name-pattern is omitted, the result data is not limited in this way.

If interfaces-only is set to 'yes', only sets that have Interface = Yes are included. If it is set to 'no' (the default), the result data is not limited in this way.

Module-pattern is a regular expression that matches zero, one or more module names in the model. The result data is limited to sets within modules that match the pattern. If module-pattern is omitted, the result data is not limited in this way.

Result data for sets from consumed modules that match module-pattern contain two additional attributes:

'INTERFACE_FROM_MODULE', which is set to 'Y',

''IMPLEMENTING_MODULE', which is set to the module name where the set originates from. The 'MODULE_NAME' attribute is set in this case to the name of the consumer module.

Depending on the set's EXPORT_TYPE attribute, for example, 'ASCII_EXPORT' or 'HTML_EXPORT', different other attributes are returned.

Example 1

This example returns set information about any sets in the model with a name containing the string 'application':

SELECT USMeta.Sets( '.*application.*' Sets )

The return value of this statement could be:

<?xml version="1.0" encoding="UTF-16"?>
<Meta>
   <Sets>
      <Set NAME="APPLICATION_RENAME" MODULE_NAME="USD" USABLE_AS_INTERFACE="N" EXPORT_TYPE="ASCII_EXPORT" SET_FORMAT_TYPE="FIX" 

          FILE_FORMAT_AS_STRING="Fixed" COLUMN_SEPERATOR="" ROW_SEPERATOR="" STRING_DELIMITER="" NUMBER_OF_ELEMENTS="4">
         <Elements>
            <Element NAME="OLDNAME" CHILD_SET="">
               <Column DATABASE_TYPE="NVARCHAR2" IO_FORMAT="" TOTAL_LENGTH="120"/>
            </Element>
            <Element NAME="NEWNAME" CHILD_SET="">
               <Column DATABASE_TYPE="NVARCHAR2" IO_FORMAT="" TOTAL_LENGTH="120"/>
            </Element>
            <Element NAME="WEB" CHILD_SET="">
               <Column DATABASE_TYPE="NCHAR" IO_FORMAT="" TOTAL_LENGTH="1"/>
            </Element>
            <Element NAME="NAMES" CHILD_SET="">
               <Column DATABASE_TYPE="NCLOB" IO_FORMAT="" TOTAL_LENGTH="2000"/>
            </Element>
         </Elements>
      </Set>
   </Sets>
</Meta>

 

Example 2

This example returns set information about a set called "CLASS_H', which turns out to be of type HTML_EXPORT:

SELECT USMeta.Sets( 'CLASS_H' Sets )

The return value of this statement could be:

<?xml version="1.0" encoding="UTF-16"?>
<Meta>
   <Sets>
      <Set NAME="CLASS_H" MODULE_NAME="USD" USABLE_AS_INTERFACE="N" EXPORT_TYPE="HTML_EXPORT" PAGE_TITLE="Class:" 
        FRAME_TEMPLATE_NAME="" HTML_LAYOUT_STYLE="TABLE" HTML_NAVIGATION_STYLE="EMBEDDED" NULL_VALUE_FILL_CHARACTER=" " 
        TEMPLATE_FILE_NAME="" STRING_DELIMITER="" NUMBER_OF_ELEMENTS="3">
         <Elements>
            <Element NAME="ID" CHILD_SET="">
               <Column DATABASE_TYPE="NUMBER" IO_FORMAT="" TOTAL_LENGTH="9"/>
            </Element>
            <Element NAME="TYPENAME" CHILD_SET="">
               <Column DATABASE_TYPE="NVARCHAR2" IO_FORMAT="" TOTAL_LENGTH="92"/>
            </Element>
            <Element NAME="CHANGED_ON" CHILD_SET="">
               <Column DATABASE_TYPE="DATETIME" IO_FORMAT="DAY, MONTH DD, YYYY HH:MI:SS AM" TOTAL_LENGTH="41"/>
            </Element>
            <Element NAME="ATTRIBUTES" CHILD_SET="ATTRIBUTE_H"/>
         </Elements>
      </Set>
   </Sets>
</Meta>
