Column Name Extractor

Creates a new table with a single row or column containing the column names. The node has two output tables: The first table contains the column headers (all columns are of type string), either as a single row containing all headers or as one row per header. The second table contains the input data, whereby the column names are changed to a default pattern (given that the corresponding option is set.)

Options

Generate new column names

If selected, the column names of both output tables will be replaced with automatically generated names by combining the prefix provided below with the corresponding column number (e.g. "Column 1", "Column 2", and so on). Otherwise, the original column names will be used.

Column: The column names are output as a single column with a row per name.

Restrain column types

All: All columns are processed.
String: Only string-compatible columns are processed, this includes e.g. XML columns.
Integer: Only integer-compatible columns are processed.
Double: Only double-compatible columns are processed. This includes integer and long columns.
