Write a DS Function like ParseYourText(Arg1, Arg2) where Arg1 is the string and Arg2 is the position you need returned (in this case usage is 1 or 2).

Tryout some code like:

hey!

Column1 = myString[1,index(field1," ",1)-1]
Column2 = myString[index(field1," ",2)+1,len(field1)]


you might have to play around with the +1 and -1 in each. and might have to trim 'myString' before you start playing around with it.

Basically, you search for the first 'space' . that gives you the end of your first answer. Then you search for the second 'space', that gives you the start of your next answer

hope it helps

terribly sorry


it should read

Column1 = field1[1,index(field1," ",1)-1]
Column2 = field1[index(field1," ",2)+1,len(field1)]

Hi,

You can use BASIC Field function,

Field (string, delimiter, instance [ ,number] )

String is your input - 234455 * 82379 in your case

delimiter is the character that delimits the substring

instance specifies which instance of delimiter terminates the substring.

number specifies the number of delimited substrings to return.
Will Returns 234455
will returns 82379

Hope this helps.

-NB

The problem is we are not sure what would be the delimitter, the only thing we are sure is we will have non numeric characters as the delimitter, it could be a space or * or + or and or any charcater and of any length, we are not sure the length of the entire field as well.

Is there a way to do this in Datastage.

Thanks for all your thoghts so far,

Any further suggestion to get this resolved would be appreciated.

Thanks

Abhi

Probably the simplest means of accomplishing the extraction of one or the other values is to create a simply Datastage Transform that has three visible arguments: DataToParse (actual data value), Delimiter (such as space), and ValueToReturn (integer value 1,2,3, etc. to indicate which value you want returned). In the definition field of the transform insert the following command:

Field(Trim(%DataToParse%),%Delimiter%,%ValueToReturn%))

Once you've created this transform, you'll be able to use it in the derivation of your target column(s). Keep in mind that a transform has pros and cons: 1) pro: it is less expensive to use a transform then to call a routine because it is compiled as part data stage job's object. 2) con: if you change the transform you'll need to recompile any jobs that are using it.

Here is what the derivation column might look like if your data was "1234 + 5678" and the transform is named ParseData:

ParseData(linkname.column," ",1) returns 1234
ParseData(linkname.column," ",3) returns 5678
ParseData(linkname.column,"+",1) returns 1234b (b represents space)
ParseData(linkname.column,"+",2) returns b5678 (b represents space)

Hope this helps!

Is this possible to accomplish through datastage in server edition if yes can you throw some ides on this.

Hi Mark,

Thanks for your help on this, but my problem i dodnot know what could be my delimitter inorder to use field function. Delimitter varies for each record and it could be any value other than numeric as i mentioned, my problem is i cannot use any defined delimitter.

I should have a solution in which i should be abble to parse any NON Numeric characters of any length in between the numeric values as my delimitter.

Is this possible. If yes how can we accomplish this.


Thanks

Original post at 13:21 (my time). Solution posted by Ken at 14:16. Now 16:34. Seems like becoming a premium member so that you can see the solution would be a real bargain.

The MatchField() function will work in this case.
MatchField(InLink.TheString, "0N0X0N",1) for the first numeric field, MatchField(InLink.TheString, "0N0X0N",3) for the second numeric field.

Read about this function in online help or in the DataStage BASIC manual.

Thanks a lot Ray,

I hope this will work for me, i will try with MatchField function and if i still need any further help i will get back to you. I hope i will not.

Thanks everyone for all your thoughts, inputs and suggestions.

I really appreciate all your help and support.

Thanks
