Merge Data Tables

[Beere_Plays]

Hey!

I Have two Data Tables with the Columns:

DT1:
Event, Date

DT2:
Date

So now my Two Databases looks like this:

DT1:

Event,Date ← Column
Event1,
Event2,
Event3,

DT2:

Date ← Column
Date1,
Date2,
Date3,

So Now i want to Merge this Two Databases to look like this:

Event,Date
Event1,Date1
Event2,Date2
Event3,Date3

How do i do this???

it is a side by side merge case:

How to copy one column from DT A to another column DT B - LINQ query

@Hiba_B Assumptions: take A Col Values when Col is not present in B A and B DataTables have same row count So we can implement a dynamic conditional side by side merge Calculate the cols not present in B: [grafik] [grafik] [grafik] prepare dt 3 and add missing cols /transfer also other col settings e.g. datatype [grafik] [grafik] Merge rows: [grafik] (From i In Enumerable.Range(0,dt2.Rows.Count) Let raB = dt2.Rows(i).ItemArray Let raA = arrMissingCols.Select(Function (x) dt1.Rows(i…

How to merge the excel table properly

@Vi_ciel have a look on following flow, supporting different rows count e.g. on dt1, dt2 [grafik] With datatable merge details: [grafik] input / output: [grafik] Kindly note: in case of multiple datatables will have the same column name, it has to be handled in advance by making the col names unique find starter help here: SideBySideMerge_AlsoDifferentRCnts.xaml (10.8 KB)

For Each Row and create an index variable for the For Each loop. Change the Assign to:

CurrentRow("Date") = dt2(index)("Date").Tostring

Note: This only works if both dt1 and dt2 has the same number of rows.

(Pic is just help with different same scenario)

If the order and number of rows are same…then you can directly do a add data column on dt1 with column as dt2.Columns(“date”)
