JSON UpdateNumber vs UpdateInt

Demonstrates UpdateNumber vs UpdateString. SQL Server

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    DECLARE @sTmp0 nvarchar(4000)
    DECLARE @json int
    EXEC @hr = sp_OACreate 'Chilkat.JsonObject', @json OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN
    END

    --  If a number is too large for a 32-bit signed integer, then call UpdateNumber instead of UpdateInt.
    --  The large integer is passed to UpdateNumber as a string, but in the JSON it will be an integer.

    --  For example:
    DECLARE @success int
    EXEC sp_OAMethod @json, 'UpdateNumber', @success OUT, 'largeNumber', '6884556842'

    --  If the integer is small enough for a 32-bit signed integer, then use UpdateInt:
    EXEC sp_OAMethod @json, 'UpdateInt', @success OUT, 'reasonableInt', 123456

    EXEC sp_OASetProperty @json, 'EmitCompact', 0
    EXEC sp_OAMethod @json, 'Emit', @sTmp0 OUT
    PRINT @sTmp0

    --  The output:
    --  Notice the large number passed as a string does not have quotes in the JSON

    --  {
    --    "largeNumber": 6884556842,
    --    "reasonableInt": 123456
    --  }
