  Hi,

  I have a json files inside nvarchar(MAX) column, the structure is like below.

  I need a query which would show:

  SourceType, JournalID, SourceID, JournalLines.AccountType,  JournalLines.JournalLineID,  JournalLines.TaxName,  JournalLines.TrackingCategories

  The number of JournalLines in each journal can be diffrent, normally 5-10 of them.

  Any ideas?

  Thanks

  {
  "SourceType": 18,
  "JournalID": "sdfdsf-fdfs-dfdf-dfdfd-dfdsfsfdd",
  "SourceID": "sdfsdf-sdfds-sdf-dfd-sdfsdf",
  "JournalLines": [
  {
  "AccountType": 3,
  "JournalLineID": "sdfsdfsd-sdfsdf-sdfsd-sdfsdf-sdfsdf",

  "TrackingCategories": []
