Simple Type and Complex Type Parameters

A simple type parameter can contain only a basic type, and can be compared with a variable in a programming language. It cannot contain other elements, and it cannot have attributes. Examples of simple types are string and integer.

When checking a web service method in USoft and generating parameters, data types are filled in with simple types as follows:

USoft Data Type	XML Data Type
DOUBLE PRECISION, FLOAT, REAL	xsd:double
BIT	xsd:Boolean
CHAR	xsd:string
VARCHAR, VARCHAR2	xsd:string
LONG, LONG VARCHAR, TEXT, CLOB	xsd:string
MONEY, SMALLMONEY	xsd:string
DATE, DATETIME, SMALLDATETIME	xsd:dateTime (*)
TIME, TIMESTAMP	xsd:dateTime
INT, INTEGER, SMALLINT, TINYINT	xsd:int
NUMBER, NUMERIC, DECIMAL with decimals	xsd:double
NUMBER, NUMERIC, DECIMAL without decimals	xsd:int

(*) The dateTime XML data type has format: YYYY-MM-DDTHH24:MI:SS. In the Definer, for a simple type parameter, use a domain with IO format: YYYY-MM-DD"T"HH24:MI:SS

A complex type parameter is an XML element that can include attribute values or a content model that contains other elements (structures, objects, and arrays). Complex type parameters are specified in USoft using namespaces.

When creating an XML schema definition, each element and attribute has simple or complex content and is of simple or complex type. A complexType element is used to define a user type, which can contain multiple elements and attributes.

TIP:

When retrieving values from a complex type input parameter, use the apply or value method of the USXSL component, and specify the correct namespace. For example, if the value of an InputParameter parameter is:

</person>

You can use the USXSL component as follows:

USXSL.value(

:InputParameter

,'/ns:person/ns:FirstName'

,'xmlns:ns="urn:myNameSpace"'

)
