## PyAgg Helper Function
|
||
|
|
|
||
|
|
### CDB_pyAgg (columns Numeric[])
|
||
|
|
|
||
|
|
Currently it's not possible to pass a multidiemensional array between plpsql and plpythonu. This function aims to
|
||
|
|
help fix that by aggergating the columns provided in the argument across rows in to a rows * columns + 1 length 1D array. The first element of the array is the array\_length of the columns argument so that python can reconstruct
|
||
|
|
the 2D array.
|
||
|
|
|
||
|
