UnresolvedTableValuedFunction Logical Operator¶

UnresolvedTableValuedFunction is a unresolved leaf logical operator that represents a table-valued function.

UnresolvedTableValuedFunction is resolved into a concrete LogicalPlan by ResolveFunctions logical analysis rule.

Creating Instance¶

UnresolvedTableValuedFunction takes the following to be created:

• Name
• Function Arguments (Expressions)
• isStreaming flag (default:false)

UnresolvedTableValuedFunction is created when:

• UnresolvedTableValuedFunction is requested to apply
• AstBuilder is requested to parse a table-valued function in a SQL statement

Creating UnresolvedTableValuedFunction¶

apply(
  name: FunctionIdentifier,
  functionArgs: Seq[Expression]): UnresolvedTableValuedFunction
apply(
  name: String,
  functionArgs: Seq[Expression]): UnresolvedTableValuedFunction

apply creates a UnresolvedTableValuedFunction.
