Extract Numeric and Special Characters Separately

I have column in a table with values stored as

Cost

499.00
£ 7.75
£ 7.75
250.00
£ 5.99
$ 6.05

Now, I need to store these values to another table like

Currency     Cost
RS           499.00
£            7.75
£            7.75 
RS           250.00 
£            5.99 
$            6.0开发者_高级运维5   

Plz let me the Query how to do this....

insert DestinationTable(Cost, Currency)
select
    case when delimiterIndex > 0 then left(Cost, delimiterIndex) else 'RS' end as Currency,
    right(Cost, len(Cost) - delimiterIndex) as Cost
from
(
    select charindex(' ', Cost) delimiterIndex, *
    from SourceTable
) tt

I'd use Perl for this...

#!/usr/bin/perl
use strict;
use warnings;

open(FH,"<data.txt");

my @lines=<FH>;

print "Currency"."\t"."Cost\n";

foreach my $line (@lines){
    $line=~s/\n//g;
    if($line ne ""){
        my @split1=split(/\s+/,$line);
        if($split1[0]=~m/[0-9.]/){
            print "\t".$split1[0]."\n";
        }else{
            print $split1[0]."\t".$split1[1]."\n";
        }
    }
}

You can use SQL-Server string functions:

# Currency
SELECT SUBSTRING(<value>, 1, CHARINDEX(' ', <value>))

# Amount
SELECT SUBSTRING(<value>, CHARINDEX(' ', <value>), LEN(<value>))

You could create a regex CLR assembly like this one and specify in your query what to match on.

Probably a bit more work than the other suggestions but you could re-use the assembly elsewhere should you need it.

SELECT
  Currency = COALESCE(NULLIF(LEFT(Cost, CostStart - 1), ''), 'RS'),
  Cost = SUBSTRING(Cost, CostStart, LEN(Cost) - CostStart + 1)
FROM (
  SELECT
    Cost,
    CostStart = PATINDEX('%[0-9]%', Cost)
  FROM atable
) s

This will work even when there's no space between the currency symbol and the sum.

StringBuffer alpha = new StringBuffer(), num = new StringBuffer(), special = new StringBuffer();

                    final String txt= txtview2.getText().toString();
                    alpha1.setText(txtview2.getText().toString());
                    num1.setText(txtview2.getText().toString());
                    special1.setText(txtview2.getText().toString());

                    for (int i=0; i<txt.length(); i++)
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   {
