Kirill Tkalenko updated IGNITE-28739:
-------------------------------------
Description:
By analogy with various DBMS systems such as
[oracle|https://docs.oracle.com/en/database/oracle/oracle-database/12.2/sqlrf/SELECT.html],
[postgresql|#SQL-LIMIT], and [H2|#select], it is proposed to add the ability
to use expressions to FETCH.
Currently, it's in
[calcite|https://calcite.incubator.apache.org/docs/reference.html]
{noformat}
[ FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY ]{noformat}
, but the proposal is to make it
{noformat}
[ FETCH { FIRST | NEXT } [ count | (expression) ] { ROW | ROWS } ONLY
]{noformat}
.
I didn't encounter any objections from the community on [dev
list|https://lists.apache.org/thread/2nq9y7l2pc2owv56nkd40gohvholbq87] (Add
expression for FETCH FIRST | NEXT rows only in Calcite SQL Engine).
