try_to_timestamp

Parses the col with the format to a timestamp. The function always returns null on an invalid input with/without ANSI SQL mode enabled. The result data type is consistent with the value of configuration spark.sql.timestampType.

For the corresponding Databricks SQL function, see try_to_timestamp function.

Syntax

from pyspark.databricks.sql import functions as dbf

dbf.try_to_timestamp(col=<col>, format=<format>)

Parameters

Parameter	Type	Description
col	pyspark.sql.Column or str	column values to convert.
format	literal string, optional	format to use to convert timestamp values.

Examples

from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('1997-02-28 10:30:00',)], ['t'])
df.select(dbf.try_to_timestamp(df.t)).show()
df = spark.createDataFrame([('1997-02-28 10:30:00',)], ['t'])
df.select(dbf.try_to_timestamp(df.t, dbf.lit('yyyy-MM-dd HH:mm:ss'))).show()
origin = spark.conf.get("spark.sql.ansi.enabled")
spark.conf.set("spark.sql.ansi.enabled", "true")
try:
df = spark.createDataFrame([('malformed',)], ['t'])
df.select(dbf.try_to_timestamp(df.t)).show()
finally:
spark.conf.set("spark.sql.ansi.enabled", origin)
