Returns a linestring geometry whose points are the non-empty points of the geometries in the input array of geometries, which are expected to be points, linestrings, or multipoints.

For the corresponding Databricks SQL function, see st_makeline function.

Syntax

Python

from pyspark.databricks.sql import functions as dbf

dbf.st_makeline(col=<col>)

Parameters

Parameter	Type	Description
col	pyspark.sql.Column or str	An array of Geometry values.

Parameter	Type	Description
col	pyspark.sql.Column or str	An array of Geometry values.

Examples

Python

from pyspark.databricks.sql import functions as dbf
from pyspark.sql.functions import array, expr
df = spark.createDataFrame([(['POINT(1 2)','POINT(3 4)'],)], ['wkt_array'])
df.select(dbf.st_astext(dbf.st_makeline(expr("transform(wkt_array, wkt -> st_geomfromtext(wkt))"))).alias('result')).collect()

Output

[Row(result='LINESTRING(1 2,3 4)')]
