-----------------------------------
Assignee: Jiajun Xie
> Invalid unparse for TIMESTAMP with SparkSqlDialect
> --------------------------------------------------
>
> Key: CALCITE-6121
> URL: https://issues.apache.org/jira/browse/CALCITE-6121
> Project: Calcite
> Issue Type: Bug
> Reporter: Guillaume Massé
> Assignee: Jiajun Xie
> Priority: Minor
>
> In Apache Spark Timestamps does not have precision:
> [https://spark.apache.org/docs/latest/sql-ref-datatypes.html]
>
> When parsing
> {code:java}
> SELECT CAST("2023-11-10" AS TIMESTAMP) {code}
> The unparsed query gives:
> {code:java}
> SELECT CAST("2023-11-10" AS TIMESTAMP(0)) {code}
> In spark-shell:
> {code:java}
> scala> spark.sql("""SELECT CAST("2023-11-10" AS TIMESTAMP)""").show()
> +-----------------------------+
> |CAST(2023-11-10 AS TIMESTAMP)|
> +-----------------------------+
> | 2023-11-10 00:00:00|
> +-----------------------------+
> scala> spark.sql("""SELECT CAST("2023-11-10" AS TIMESTAMP(0))""").show()
> org.apache.spark.sql.catalyst.parser.ParseException:
> [UNSUPPORTED_DATATYPE] Unsupported data type "TIMESTAMP(0)".(line 1, pos
> 28)== SQL ==
> SELECT CAST("2023-11-10" AS TIMESTAMP(0))
