# TableFunction 

###

#### case class TableFunction(funcName: String) extends Product with Serializable

Looks up table functions by funcName and returns tableFunction object which can be used in DataFrame.join and Session.tableFunction methods.

It can reference both system-defined table function and user-defined table functions.

Example

    import com.snowflake.snowpark.functions._
    import com.snowflake.snowpark.TableFunction

    session.tableFunction(
      TableFunction("flatten"),
      Map("input" -> parse_json(lit("[1,2]")))
    )

    df.join(TableFunction("split_to_table"), df("a"), lit(","))

funcName

  table function name, can be a short name like func or a fully qualified name like database.schema.func
