CountColumn

Specify the name of the input table column that contains the number of times a path was traveled.

Delimiter

Specify the single Unicode character delimiter that separates symbols in the path string.

If delimiter is backslash (\) or single quotation mark ('), you must precede it with the escape character, backslash (\). For example:

Delimiter ('\\') -- Delimiter is backslash
Delimiter ('\'') -- Delimiter is single quotation mark

ParentColumn

Specify the name of the input table column that contains the parent nodes. The PARTITION BY clause in the function call must include this column.

PartitionNames

Specify the names of the columns that the PARTITION BY clause specifies. The function uses these names for output table columns.

This syntax element and the PARTITION BY clause must specify the same names in the same order. One partition_column must be parent_column.
