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 ' )

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