SELECT  DataSourceDatasetRecordID, Data.query('//Investment') as InvesValue from sct_DataSourceDatasetRecord where (DataSourceDatasetID = '117'or DataSourceDatasetID = '118') 

-- Get the XML node value using data function. See output #3
SELECT  DataSourceDatasetRecordID, Data.query('data(//Investment)') as InvesValue from sct_DataSourceDatasetRecord where (DataSourceDatasetID = '117'or DataSourceDatasetID = '118')
