Subject Importing currency figures with currency indicator to Hive from CSV

Hi,

 

 

How to do convert a column stored as String in Hive into Decimal if possible.

 

The excel looks like this

 


Invoice Number

Payment date

Net

VAT

Total


360

10/02/2014

£10,000.00

£2000.00

£12,000.00

 

And the file (before bzip2) looks like this on imported directory in Linux

Invoice Number,Payment date,Net,VAT,Total

360,10/02/2014,"▒12,000.00",▒2000.00,"▒12,000.00"

 

Once the data inserted from the external table into Hive (as string), looks like below

+-------------------+-----------------+--------------+-------------+--------------+--+

| t2.invoicenumber  | t2.paymentdate  |    t2.net <http://t2.net>     |   t2.vat   
|   t2.total   |

+-------------------+-----------------+--------------+-------------+--------------+--+

| 360               | 10/02/2014      | ?10,000.00   | ?2000.00    | ?12,000.00   |

|

Is there any way to resolve this column to decimal format?

 

Thanks

 

 

Dr Mich Talebzadeh
