How can I get different values from a JSON array?

I have a SQL table containing 2 columns – first Column is the ID of the users and the second column holds the JSON Phone information. The phone information consist of Work, Home phones and whether it is a mobile or a landline. It is not always that a user have both – mobile and Landline.

I’m now trying to select the users work phones so I have separate columns for the User ID, the Work Mobile number and the Work Landline Number. So far I have managed to get on type of phone information – the Work/mobile. But I can’t figure out how to also get the Work/Landline information in the same select. And if a user on has the landline, then mobile should be NULL in the column and also the other way. I have tried to add an extra CROSS APPLY with the where clause = Landline. But it just makes things worse…

This is What I’m trying to achieve

Any help is appreciated

This is the JSON string from the table

This is the T-SQL query I’m using

SELECT [wd:Worker_ID] AS Worker_ID,
       [Work_Mobile_Number]   
     
FROM [Employee_Master_Data_Source] 

CROSS APPLY OPENJSON ([wd:Personal_Data])
WITH (Phone_Details NVARCHAR(MAX) '$."wd:Contact_Data"."wd:Phone_Data"' AS JSON)

CROSS APPLY OPENJSON (Phone_Details)
WITH (Work_Mobile_Number    NVARCHAR(50) '$."@wd:Phone_Number_Without_Area_Code"',
      Phone_Usage           NVARCHAR(50) '$."wd:Usage_Data"."wd:Type_Data"."wd:Type_Reference"."@wd:Descriptor"',
      Phone_Type            NVARCHAR(50) '$."wd:Phone_Device_Type_Reference"."@wd:Descriptor"')

WHERE Phone_Usage = 'Work'
AND   Phone_Type  = 'Mobile'

Answers

You can use some conditional aggregation as below (DB Fiddle)

SELECT [wd:Worker_ID] AS Worker_ID,
       ca.*
FROM [Employee_Master_Data_Source] 
CROSS APPLY
(
    SELECT 
        Work_Mobile_Number = MAX(CASE WHEN Phone_Usage = 'Work' AND   Phone_Type  = 'Mobile' THEN Phone_Number_Without_Area_Code END),
        Work_Landline_Number= MAX(CASE WHEN Phone_Usage = 'Work' AND   Phone_Type  = 'Landline' THEN Phone_Number_Without_Area_Code END)
    FROM 
      OPENJSON ([wd:Personal_Data])
      WITH (
        Phone_Details NVARCHAR(MAX) '$."wd:Contact_Data"."wd:Phone_Data"' AS JSON
      )
    CROSS APPLY OPENJSON (Phone_Details)
      WITH (
        Phone_Number_Without_Area_Code    NVARCHAR(50) '$."@wd:Phone_Number_Without_Area_Code"',
        Phone_Usage           NVARCHAR(50) '$."wd:Usage_Data"."wd:Type_Data"."wd:Type_Reference"."@wd:Descriptor"',
        Phone_Type            NVARCHAR(50) '$."wd:Phone_Device_Type_Reference"."@wd:Descriptor"'
      )
) ca

Please try the following solution.

SQL

-- DDL and sample data population, start
DECLARE @tbl TABLE (ID INT IDENTITY PRIMARY KEY, jdata NVARCHAR(MAX));
INSERT INTO @tbl (jdata) VALUES
