Support "Returning" part of DELETE statement. #1527
Description
Hello!
Our user expecting some problem with DELETE statement with returning clause.
dbeaver/dbeaver#15946
Because delete from t returning *; statement can't be parsed
Please, add support of RETURNING clause in DELETE statement.
Encountered unexpected token: "returning" "RETURNING" at line 1, column 15. Was expecting one of: ";" "ACTION" "ACTIVE" "ALGORITHM" "ARCHIVE" "ARRAY" "AS" "AT" "BYTE" "CASCADE" "CASE" "CAST" "CHANGE" "CHAR" "CHARACTER" "CHECKPOINT" "COLUMN" "COLUMNS" "COMMENT" "COMMIT" "COSTS" "CYCLE" "DBA_RECYCLEBIN" "DESC" "DESCRIBE" "DISABLE" "DISCONNECT" "DIV" "DO" "DUMP" "DUPLICATE" "ENABLE" "END" "EXCLUDE" "EXTRACT" "FALSE" "FILTER" "FIRST" "FLUSH" "FN" "FOLLOWING" "FORMAT" "FULLTEXT" "HISTORY" "INDEX" "INSERT" "INTERVAL" "ISNULL" "JSON" "KEY" "LAST" "LEADING" "LIMIT" "LINK" "LOCAL" "LOG" "MATERIALIZED" "NO" "NOLOCK" "NULLS" "OF" "OPEN" "ORDER" "OVER" "PARALLEL" "PARTITION" "PATH" "PERCENT" "PRECISION" "PRIMARY" "PRIOR" "QUERY" "QUIESCE" "RANGE" "READ" "RECYCLEBIN" "REGISTER" "REPLACE" "RESTRICTED" "RESUME" "ROW" "ROWS" "SCHEMA" "SEPARATOR" "SEQUENCE" "SESSION" "SHUTDOWN" "SIBLINGS" "SIGNED" "SIZE" "SKIP" "SUSPEND" "SWITCH" "SYNONYM" "SYSTEM" "TABLE" "TABLESPACE" "TEMP" "TEMPORARY" "TIMEOUT" "TO" "TOP" "TRUE" "TRUNCATE" "TRY_CAST" "TYPE" "UNQIESCE" "UNSIGNED" "USER" "USING" "VALIDATE" "VALUE" "VALUES" "VIEW" "WHERE" "XML" "ZONE" <EOF> <K_DATETIMELITERAL> <K_DATE_LITERAL> <K_NEXTVAL> <K_STRING_FUNCTION_NAME> <S_CHAR_LITERAL> <S_IDENTIFIER> <S_QUOTED_IDENTIFIER> SQL Example
This statement doesn't work.
delete from t returning *;
And Update statement already support returning statement:
update t set a = 1 returning *;
I see that UPDATE supports returning clause, and DELETE statement - don't.
