------------------------------------
Summary: The parser rejects the example hints from the
documentation
Key: CALCITE-7498
URL: https://issues.apache.org/jira/browse/CALCITE-7498
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.41.0
Reporter: Mihai Budiu
Section [https://calcite.apache.org/docs/reference.html#sql-hints] in the
documentation gives the following example:
{code:java}
SELECT /*+ hint1, hint2(a=1, b=2) */
...
FROM
tableName /*+ hint3(5, 'x') */
JOIN
tableName /*+ hint4(c=id), hint5 */
... {code}
For assignments the grammar (as described in the next paragraph and in the
implementation) requires a string literal on the RHS, thus the parser rejecting
this example.
We can change either the example or the grammar. I suspect the actual intent is
for the grammar to accept other literals besides string in this position.
