Select query help


As here i am not updating for particular column, this wont help

Name. Value. Amount pending
Shilpa. 56886. 747
Liper. -241. -241
Hudd. -241. 786

Data will be like this, where multiple volumn can have value as -241
I want to change only value column


for your table try below query it will give you correct resut.

(From d In dtData.AsEnumerable
Let u = If(d(1).ToString.Trim.Equals(“-241”),“0”,d(1).ToString)
Select dtResult.Rows.Add(New Object(){d(0),u,d(2)})).CopyToDataTable

Instead of d(1) can i gv d("value)


yeah try like that will work i guess. relace d(1) with d(“value”)

Refer the attached updated work flow check and let me know is that what you are expecting.

I have 83 columns, any way to copy the columns directly

@Shilpa_Mohanty could you please tell us the complete requirement, so we can have a proper view on it.


I have 85 columns.
5 columns have values “-241”
I want to update “-241” to “0” in 3 columns out of 5
Thats the complete requirement

@prasath_S and @kirankumar.mahanthi1
can you please help me

@Shilpa_Mohanty Please try this,

1. Use invoke code activity,


2. In edit arguments pass datatable as below,

Code inside invoke code,

For Each dtRow As DataRow In dt.Rows
	For Each colName As String In {"value","AmtPending","Amttaken"}
		If (dtRow(colName).ToString = "-2.41") Then dtRow(colName) = 0
	Next colName
Next dtRow

May I know what is dt1

As I took readrange and stored the value in dt

Facing below error,

for general introduction

for a first analysis / selection approach we would recommend also, to check how many rows are affected. (Just use a count statement)

Then lets decide, which approach will fit the best

Yeah you should replace dt1 with your data table contains those 83 columns.


Tried invoke code and getting the error screenshot which is pasted in the thread
Tried linq but here manually I have to pass all the column names
Cant use for each as I have 40k records of data

NOTE: there are around 1000 rows in each column, which has -241 value, I have to change it to 0

How to overcome this
