Hello,
I have a HANA SQL statement question.
I have the following table defined:
CREATE COLUMN TABLE TEST_SCHEMA.TB_TEST_DATA
(ROW_ID INTEGER PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY,
FLD1 VARCHAR(255) NOT NULL,
FLD2 VARCHAR(255) NOT NULL,
FLD3 VARCHAR(255) NOT NULL,
FLD4 VARCHAR(255) NOT NULL,
FLD5 VARCHAR(255) NOT NULL,
FLD6 VARCHAR(255) NOT NULL,
FLD7 VARCHAR(255) NOT NULL,
FLD8 VARCHAR(255) NOT NULL,
FLD9 VARCHAR(255) NOT NULL,
FLD10 VARCHAR(255));
I have loaded the above table with the following data:
insert into TEST_SCHEMA.TB_TEST_DATA
(ROW_ID, FLD1, FLD2, FLD3, FLD4, FLD5, FLD6, FLD7, FLD8, FLD9, FLD10)
VALUES (1, 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1');
insert into TEST_SCHEMA.TB_TEST_DATA
(ROW_ID, FLD1, FLD2, FLD3, FLD4, FLD5, FLD6, FLD7, FLD8, FLD9, FLD10)
VALUES (2,'VAL 1', 'VAL 1', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2');
insert into TEST_SCHEMA.TB_TEST_DATA
(ROW_ID, FLD1, FLD2, FLD3, FLD4, FLD5, FLD6, FLD7, FLD8, FLD9, FLD10)
VALUES (3,'VAL 2', 'VAL 2', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1', 'VAL 1');
insert into TEST_SCHEMA.TB_TEST_DATA
(ROW_ID, FLD1, FLD2, FLD3, FLD4, FLD5, FLD6, FLD7, FLD8, FLD9, FLD10)
VALUES (4,'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2', 'VAL 2');
The following UNION ALL select executes successfully returning all 3 rows:
SELECT *
FROM TEST_SCHEMA.TB_TEST_DATA
WHERE (FLD1 = 'VAL 1' AND FLD2 = 'VAL 1' AND FLD3 = 'VAL 1')
UNION ALL
SELECT *
FROM TEST_SCHEMA.TB_TEST_DATA
WHERE (FLD1 = 'VAL 1' AND FLD2 = 'VAL 1' AND FLD3 = 'VAL 2')
UNION ALL
SELECT *
FROM TEST_SCHEMA.TB_TEST_DATA
WHERE (FLD1 = 'VAL 2' AND FLD2 = 'VAL 2' AND FLD3 = 'VAL 1')
When I combine the top 2 selects using OR in the WHERE clause and execute it all 2 rows are returned.
SELECT *
FROM TEST_SCHEMA.TB_TEST_DATA
WHERE (FLD1 = 'VAL 1' AND FLD2 = 'VAL 1' AND FLD3 = 'VAL 1')
OR (FLD1 = 'VAL 1' AND FLD2 = 'VAL 1' AND FLD3 = 'VAL 2')
Result
------
ROW_ID;FLD1;FLD2;FLD3;FLD4;FLD5;FLD6;FLD7;FLD8;FLD9;FLD10
1;VAL 1;VAL 1;VAL 1;VAL 1;VAL 1;VAL 1;VAL 1;VAL 1;VAL 1;VAL 1
2;VAL 1;VAL 1;VAL 2;VAL 2;VAL 2;VAL 2;VAL 2;VAL 2;VAL 2;VAL 2
When I combine the bottom 2 selects using OR in the WHERE clause and execute it the database returns an error and crashes.
SELECT *
FROM TEST_SCHEMA.TB_TEST_DATA
WHERE (FLD1 = 'VAL 1' AND FLD2 = 'VAL 1' AND FLD3 = 'VAL 2')
OR (FLD1 = 'VAL 2' AND FLD2 = 'VAL 2' AND FLD3 = 'VAL 1')
The following error is received error:
Could not execute 'SELECT * FROM TEST_SCHEMA.TB_TEST_DATA WHERE (FLD1 = 'VAL 1' AND FLD2 = 'VAL 1' AND FLD3 = 'VAL 2') OR ...' in 4:29.324 minutes .
Data receive failed.
Does anyone know what might be causing this issue?
Our current configuration is as follows:
SAP HANA studio
Version: 1.00.81.0
Internal Version: 1.81.2 (1812)
Thanks,
Victoria
