----------------------------------
Summary: Fix parameter case sensitive error for test
passing/rejecting filter API
Key: FLINK-6632
URL: https://issues.apache.org/jira/browse/FLINK-6632
Project: Flink
Issue Type: Sub-task
Reporter: sunjincheng
Assignee: sunjincheng
TableAPI {{testAllPassingFilter}}:
{code}
val t = util.addTable[(Int, Long, String)]('int, 'long, 'string)
val resScala = t.filter(Literal(true)).select('int as 'myInt, 'string)
val resJava = t.filter("TrUe").select("int as myInt, string")
{code}
We got error:
{code}
org.apache.flink.table.api.ValidationException: Cannot resolve [TrUe] given
input [int, long, string].
{code}
The error is caused by :
{code}
lazy val boolLiteral: PackratParser[Expression] = ("true" | "false") ^^ {
str => Literal(str.toBoolean)
}
{code}
I want import the method as follow:
{code}
lazy val boolLiteral: PackratParser[Expression] =
("(t|T)(r|R)(u|U)(e|E)".r | "(f|F)(a|A)(l|L)(s|S)(e|E)".r) ^^ { str =>
Literal(str.toBoolean)}
{code}
Is there any drawback to this improvement? Welcome anyone feedback ?
