Name

WSDL_IMPORT_UDT — Returns a string containing a UDT definition

Synopsis

varchar WSDL_IMPORT_UDT ( in url varchar ,
  in f varchar ,
  in exec any );
 

Description

This function is used to create a user defined type (UDT) definition automatically based on a WSDL file. The source WSDL is supplied via a URL.

The returned definition can be saved to a file and/or executed automatically to provide instant access to the new UDT.

[Note] Note:

To save the file you must have an appropriate ACL defined.

Parameters

url

The URI of the target WSDL file to build a UDT definition of.

f

The name of the file if the definition is to be saved. This will produce a file on the file system under the server root directory.

The default value is NULL, which will not create a file.

exec

This flag indicates whether the definition should be immediately executed upon import. This takes the form of 0 or 1. The default value of 0 will not execute the definition.

Return Types

This function returns the text of the UDT definition as a varchar.

Examples

Example 24.451. Simple example of a WSDL driven UDT

Web Service proxy wrapper for Redcoal SMS SOAP interface: 

SQL> WSDL_IMPORT_UDT ('http://xml.redcoal.com/soapserver.dll/wsdl/ISoapServer', 'redcoal.sql');

This will create the following file on file system called redcoal.sql :

-- Automatically generated code
-- imported from WSDL URI: "http://xml.redcoal.com/soapserver.dll/wsdl/ISoapServer"
-- UDT class
drop type "ISOAPServerservice"
;

create type "ISOAPServerservice"
  as
    (
      debug int default 0,
      url varchar default 'http://xml.redcoal.com/soapserver.dll/soap/ISoapServer',
      request varchar,
      response varchar
    )
-- Binding: "http://tempuri.org/:ISOAPServerbinding"

method "SendTextSMS"
       (
        "strInSerialNo" any,
        "strInSMSKey" any,
        "strInRecipients" any,
        "strInMessageText" any,
        "strInReplyEmail" any,
        "strInOriginator" any,
        "iInType" any,
        "strOutMessageIDs" any,
        "return" any
       ) returns any,

.... more methods follows ; do not supplied for brevity

method "RedWebServiceVersion"
       (
        "return" any
       ) returns any,

method style () returns any

This script, executed via the ISQL tool, or automatically if the 'exec' flag is set to 'true', will define the desired UDT in database. Developing a simple application for checking the Redcoal SMS SOAP interface could be done as follows using a stored procedure: 

create procedure
redcoaltest ()
{
  declare svc "ISOAPServerservice";
  declare res nvarchar;
  svc := new "ISOAPServerservice" ();
  svc."RedWebServiceVersion" (res);
  result_names (res);
  result (res);
}
;

Which could have the following output:

SQL> redcoaltest();
res
NVARCHAR
