CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    -- Important: Do not use nvarchar(max).  See the warning about using nvarchar(max).
    DECLARE @sTmp0 nvarchar(4000)
    -- This example requires Chilkat v9.5.0.63 or greater.

    DECLARE @json int
    -- Use "Chilkat_9_5_0.JsonObject" for versions of Chilkat < 10.0.0
    EXEC @hr = sp_OACreate 'Chilkat.JsonObject', @json OUT

    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN

    EXEC sp_OASetProperty @json, 'EmitCompact', 0

    -- The UpdateString method updates or adds a string member.
    -- It also auto-creates the objects and/or arrays that
    -- are missing.  For example:
    DECLARE @success int
    EXEC sp_OAMethod @json, 'UpdateString', @success OUT, 'test.abc[0].xyz', 'Chicago Cubs'

    -- The JSON now contains:
    EXEC sp_OAMethod @json, 'Emit', @sTmp0 OUT
    PRINT @sTmp0

    -- {
    --   "test": {
    --     "abc": [
    --       {
    --         "xyz": "Chicago Cubs"
    --       }
    --     ]
    --   }

    EXEC sp_OAMethod @json, 'UpdateString', @success OUT, 'test.abc[0].xyz', 'Chicago Cubs are going to win the World Series!'
    EXEC sp_OAMethod @json, 'Emit', @sTmp0 OUT
    PRINT @sTmp0

    -- {
    --   "test": {
    --     "abc": [
    --       {
    --         "xyz": "Chicago Cubs are going to win the World Series!"
