Alex Daniels updated DERBY-6777:
--------------------------------
Description:
To reproduce: merge 2 tables where the recipient has a generated pk and the
source table has at least 6 rows of data.
Example:
{code:sql}
CREATE TABLE COLTEST.TEMPDATA1 (id BIGINT not null primary key GENERATED BY
DEFAULT AS IDENTITY (START WITH 1, INCREMENT BY 1), DATA1 VARCHAR(1024) not
null, DATA2 VARCHAR(50));
CREATE TABLE COLTEST.TEMPDATA2 (DATA1 VARCHAR(50) not null, DATA2 VARCHAR(50));
INSERT INTO COLTEST.TEMPDATA2 (DATA1, DATA2) VALUES ('rowA', 'Ad2'),('rowB',
'Bd2'),('rowC', 'Cd2'),('rowD', 'Dd2'),('rowE', 'Ed2'),('rowF', 'Fd2');
MERGE INTO COLTEST.TEMPDATA1 M USING COLTEST.TEMPDATA2 AS U ON M.DATA1 =
U.DATA1
WHEN NOT MATCHED THEN INSERT (DATA1, DATA2) VALUES (U.DATA1, U.DATA2);
{code}
