Description
psergei hi! Not sure if this is a bug, though it looks to be. If not, please close.
CREATE TABLE t (c INT);
|
INSERT INTO t VALUES (1); # Optional
|
SET @show_explain_probe_select_id=2;
|
SET debug_dbug='+d,show_explain_probe_join_exec_end';
|
SELECT c FROM t;
|
Will not fail/simply result in "1" output.
However,
CREATE TABLE t (c INT);
|
INSERT INTO t VALUES (1); # Optional
|
SET @show_explain_probe_select_id=2;
|
SET debug_dbug='+d,show_explain_probe_join_exec_end';
|
SET @hang=(SELECT c FROM t);
|
Will hang on 10.2, 10.3, 10.4, 10.5, 10.6 debug.
It may be a shortcoming in the debug parameter, or it may be a bug in SET handling.
