> --------------------------------------------------------------

> Key: SPARK-55054
> URL: https://issues.apache.org/jira/browse/SPARK-55054
> Project: Spark
> Issue Type: Task
> Components: SQL, Structured Streaming
> Affects Versions: 4.2.0
> Reporter: Eric Marnadi
> Priority: Major
> Labels: pull-request-available

> Extend the IDENTIFIED BY syntax to support streaming table-valued functions (TVFs), complementing the existing support for streaming tables.
> The changes include:
> - Added grammar rules for streaming TVFs with IDENTIFIED BY clause
> - Split `functionTable` into `tableFunctionCall` + clauses for consistent syntax
> - Added validation that IDENTIFIED BY is only allowed for streaming sources
> - Streaming TVFs support two syntaxes:
> 1. `STREAM tvf() IDENTIFIED BY name` - clauses inside
> 2. `STREAM(tvf()) IDENTIFIED BY name` - clauses outside (consistent with table syntax)
> - Added comprehensive test coverage for both syntaxes
