I think our SQL parser support both syntaxes. I write a test case for test it ```scala test("test") { val t = "testcat.ns1.ns2.tbl" withTable(t) { sql( s""" |CREATE TABLE $t ( | a bigint NOT NULL, | b bigint |) |USING foo |OPTIONS ( | `from` '0', | `to` '1', | `via` '2') """.stripMargin) val showDDL = getShowCreateDDL(s"SHOW CREATE TABLE $t") showDDL.foreach { i => println(i) } } } ``` -- This is an automated message from the Apache Git Service.
