Insert Column Header

KNIME Base Nodes version 4.2.3.v202011031328 by KNIME AG, Zurich, Switzerland

Updates column names of a table according to the mapping in second dictionary table. The dictionary table needs to contain two columns, one of which contains the lookup (i.e. the column names of the table to be renamed), the other column containing the new column names. The lookup column may be the RowID column.

If the assigned new value in the value column is missing, the original column name will be retained. If the lookup column contains duplicates of the original column names, the node will fail.

Options

Lookup column: The column in the 2nd input containing the "old" names of the columns.
Value column: The column in the 2nd input containing the "new" names of the columns.
Fail if no assignment in dictionary table: If selected, the node fails if there is no matching entry of a column name in the dictionary table. Otherwise it will keep the original column name

Input Ports

: Table whose columns are to be renamed.
: Table containing two columns: lookup and new value.

Output Ports

: Input table, whereby the columns are renamed according to the dictionary.
