> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API

> Labels: pull-request-available
> Fix For: 2.4.0

>
> {{ShowCreateUtil.buildShowCreateMaterializedTableRow}} always emits the
> {{FRESHNESS}} and {{REFRESH_MODE}} clauses when rendering {{SHOW CREATE
> MATERIALIZED TABLE}} output. For instance, if the FRESHNESS is globally
> configured to a fix value. Including these clauses in the output is
> misleading.
> h3. Proposal
> Add an overload of {{buildShowCreateMaterializedTableRow}} that accepts two
> flags:
> * {{boolean includeFreshness}}
> * {{boolean includeRefreshMode}}
> The existing public overload delegates to the new one with {{{}true,
> true{}}}, preserving current behavior for all OSS callers. Callers that need
> to suppress either clause can opt in via the new overload.
> h3. Scope
> * *File:*
> {{flink-table/flink-table-api-java/src/main/java/org/apache/flink/table/api/internal/ShowCreateUtil.java}}
> * No behavior change for existing callers.
> * Purely additive API.
> h3. Test plan
> Existing {{ShowCreateUtilTest}} covers the default-path overload (delegates
> with {{{}true, true{}}}) and continues to pass. A new test exercises the flag
> combinations to verify the clauses are suppressed/included as requested.
