There is a SQL config 'spark.sql.parser.escapedStringLiterals' that can be used to fallback to the Spark 1.6 behavior regarding string literal parsing. To convert the string with specific format, to timestamp in the Databricks SQL, you can use the following code expression, it will return as Date: to_timestamp(string, format) Assume current timestamp string is '10-07-2021 13:25:35′ Example to convert string from dd-MM-yyyy HH:mm:ss format to Timestamp: Spark support all Java Data formatted patterns for conversion. coalesce gives the first non- null value among the given columns or null. Following in the table below are the Spark SQL date functions these can be used to manipulate the data frame columns that contain data type values. Reading this causes an exception: val sqlContext = new org.apache.spark.sql.SQLContext . Note: 1. So, the format string should be changed to Internally, unix_timestamp creates a Column with UnixTimestamp binary . Internally, to_timestamp creates a spark-sql-Column.md#creating-instance[Column] with spark-sql-Expression-ParseToTimestamp.md[ParseToTimestamp] expression (and Literal expression for fmt). The spark.sql accepts the to_timestamp function inside the spark function and converts the given column in the timestamp. As mentioned in #83 the issue is with datetime2(0) but datetime2(x) works. Specify formats according to datetime pattern . By default, the spark.sql.legacy.sizeOfNull parameter is set to true. C h a r s e t c =.
