st_multi
Preview
Support for GEOGRAPHY values is in Public Preview. Support for GEOMETRY values is generally available.
Returns the input Geography or Geometry value as an equivalent multi geospatial value, keeping the original SRID.
For the corresponding Databricks SQL function, see st_multi function.
Syntax
Python
from pyspark.databricks.sql import functions as dbf
dbf.st_multi(col=<col>)
Parameters
Notes
Multi geospatial values and geometry collections are returned as is, with the same SRID.
Examples
Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('POINT M (1 2 4)',)], ['wkt'])
df.select(dbf.st_asewkt(dbf.st_multi(dbf.st_geomfromtext('wkt', 4326))).alias('result')).collect()
Output
[Row(result='SRID=4326;MULTIPOINT M ((1 2 4))')]
Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('MULTIPOINT ZM ((1 2 3 4))',)], ['wkt'])
df.select(dbf.st_asewkt(dbf.st_multi(dbf.st_geogfromtext('wkt'))).alias('result')).collect()
Output
[Row(result='SRID=4326;MULTIPOINT ZM ((1 2 3 4))')]
