> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.38.0

> Vertica does not support {{FETCH NEXT ? ROWS ONLY}} syntax:
> *SQL*
> {code:sql}
> SELECT * FROM dual LIMIT 1 {code}
> *actual*
> {code:sql}
> SELECT *
> FROM "dual"
> FETCH NEXT 1 ROWS ONLY
> {code}
> *expected*
> {code:sql}
> SELECT *
> FROM "dual"
> LIMIT 1
> {code}
> The fix seems to be adding this to
> [VerticaSqlDialect.java|https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/dialect/VerticaSqlDialect.java]:
> {code:java}
> @Override
> public void unparseOffsetFetch(SqlWriter writer, @Nullable SqlNode
> offset, @Nullable SqlNode fetch) {
> unparseFetchUsingLimit(writer, offset, fetch);
> }
> {code}
