SAVEASXML Function

Saves the resulting dataset of a query as an .xml file.

The following code shows the syntax of the SAVEASXML function. The first line of code is the syntax for an instance function call. The second line of code is the syntax for a static function call.

Syntax

[Ok :=] QueryVariable.SAVEASXML(FileName)  

[Ok :=] QUERY.SAVEASXML(Number, FileName)  

Parameters

QueryVariable
Type: Query

A variable that specifies the query object to save as an .xml file.

Number
Type: Integer

The ID of the query object that you want to save as an .xml file. On the View menu, choose C/AL Symbol Menu to select the query from a list. If the query that you specify does not exist, then a run-time error occurs.

FileName
Type: Text

The path and name of the file that you want to save the query to.

Return Value

Type: Boolean

true if the query dataset was saved; otherwise, false.

If you omit this optional return value and if the query cannot be saved as an .xml file, then a run-time error occurs that states that the query cannot be saved. If you include a return value, then it is assumed that you will handle any errors and no run-time error occurs, even though the query is not saved as an .xml file.

Remarks

When the SAVEASXML function is called, the dataset is generated and then saved in XML format in the file and location that is designated by the FileName parameter.

The SAVEASXML function can be called at any place in the code and does not require that the CLOSE, OPEN, or READ functions are called before it. When the SAVEASXML function is called, a new instance of the query is created. The query is implicitly opened, read, and closed. If there is currently a dataset in the opened state when the SAVEASXML function is called, then that instance is closed. This means that the following code is unauthorized because the query is not open on the second READ call.

Query.OPEN;  
Query.READ;  
Query.SAVEASXML('c:\test.xml');  
Query.READ;   

The correct code for this example is as follows.

Query.OPEN;  
Query.READ;  
Query.SAVEASXML('c:\test.xml');  
Query.OPEN;  
Query.READ;   

Example

The following example shows how to save a query with the name My Customer Query as an .xml file. The file is given the name myquery.xml and is saved on the c: drive of the computer running Microsoft Dynamics NAV Server.

This example requires that you create the following variables and text constant.

Variable name	DataType	Subtype
OK	Boolean	Not applicable
MyCustomerQuery	Query	My Customer Query

Text constant name	ENU Value
Text000	Query was not saved.

OK := MyCustomerQuery.SAVEASXML('c:\myquery.xml');  
IF NOT OK THEN  
  ERROR(Text000);  

If the file cannot be saved, then the follow message appears:

Query not saved.
