insert multiple rows into DB2 database

Question

I want to insert multiple rows into a DB2 table. I have a query that looks like this

insert into tableName 
(col1, col2, col3, col4, col5) 
values 
(val1, va         


        

Answer 1

other method

INSERT INTO tableName (col1, col2, col3, col4, col5)
select * from table(                        
                    values                                      
                    (val1, val2, val3, val4, val5),   
                    (val1, val2, val3, val4, val5),   
                    (val1, val2, val3, val4, val5),   
                    (val1, val2, val3, val4, val5)    
                    ) tmp

Answer 2

UPDATE - Even less wordy version

INSERT INTO tableName (col1, col2, col3, col4, col5) 
VALUES ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5')

The following also works for DB2 and is slightly less wordy

INSERT INTO tableName (col1, col2, col3, col4, col5) 
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5')

Answer 3

I disagree on the comment posted by Hogan. Those instructions will work for IBM DB2 Mini, but it's not the case of DB2 Z/OS.

Here is an example:

Exception data: org.apache.ibatis.exceptions.PersistenceException:
The error occurred while setting parameters

SQL: INSERT INTO TABLENAME(ID_, F1_, F2_, F3_, F4_, F5_) VALUES
 (?,          1,          ?,          ?,          ?,          ?),          
 (?,          1,          ?,          ?,          ?,          ?)


Cause: com.ibm.db2.jcc.am.SqlSyntaxErrorException: 
ILLEGAL SYMBOL ",". SOME SYMBOLS THAT MIGHT BE LEGAL ARE: FOR <END-OF-STATEMENT> NOT ATOMIC. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.25.17

So I can confirm that inline comma separated bulk inserts are not working on DB2 Z/OS (maybe you could feed it some props to get it working...)

Answer 4

I'm assuming you're using DB2 for z/OS, which unfortunately (for whatever reason, I never really understood why) doesn't support using a values-list where a full-select would be appropriate.

You can use a select like below. It's a little unwieldy, but it works:

INSERT INTO tableName (col1, col2, col3, col4, col5) 
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1

Your statement would work on DB2 for Linux/Unix/Windows (LUW), at least when I tested it on my LUW 9.7.

Answer 5

None of the above worked for me, the only one working was

insert into tableName  
select 11, 'BALOO' from sysibm.sysdummy1 union all
select 22, nullif('','') AS nullColumn from sysibm.sysdummy1

The nullif is used since it is not possible to pass null in the select statement otherwise.
