How to use cDataSet.bigCommit() to create a copy of the values in a sheet, and filter the results

In Make a copy of a worksheet we looked at how to use the .bigCommit() method of  cDataSet  to copy a table from one worksheet to another.  This method is also capable of filtering – meaning only copying rows where a particular column value equals some value. Here’s  how to copy only rows where the city is  London.

VBA

Public Sub straightCopyFilter()
    Dim ds As New cDataSet
    ds.populateData(wholeSheet("geoCoding")).bigCommit _
        wholeSheet("messAround"), True, , "city", "London"
End Sub

Google Apps Script

In this example, I am going to assume now that you are using cDataSet from an external library rather than from a local copy. You will see that we are using the functions from the Mcpher namespace.

function ds() {
  new Mcpher
      .cDataSet() 
      .populateData(Mcpher.wholeSheet("Test"))
      .bigCommit(Mcpher.wholeSheet("messAround"),true,undefined,"city","London");
}
