APPEND ANOTHER TABLE
Category: Transform / Basic
Description
This action appends another table to the current dataset. This action can operate in 2 modes:
Append rows
The other table (dataset) is appended as new rows at the bottom of the current table. Columns with the same name in both tables appear as one column in the result table. Columns in the appended table that don't exist in the main table are appended on the right.
This mode has the useful feature of preserving the order of columns of the main dataset to which the other dataset is appended.
Append columns
The other table (dataset) is appended as new columns to the right of the current dataset. Columns from the appended table with the same name as in the main table are automatically renamed. The length of the resulting table is the longest length of the two tables.
Use cases (Append rows)
- Concatenation of similar datasets.
- Incremental loading.
To append multiple datasets, apply the "Append" action multiple times.
