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.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.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)
