ERROR 1366 (HY000): Incorrect integer value: 'x' for column 'y' at row 1

Question

I'm trying to read a csv file and load the values to a mysql table.

My csv file looks like this:

"1026235","2172","Werdmühlestrasse","4","400","Werdmühlestrasse 4","3","real","BB","261AA01857","3169179","2683137.449","1247708.724","8001","0","Zürich","AA1750","","K","1","Lindenhof","13","1301","Zürichberg","Altstadt","St.Peter u Paul","St.Peter","1026238","562","Fortunagasse","15","1500","Fortunagasse 15","3","real","BB","261AA01852","140709","2683163.645","1247502.811","8001","0","Zürich","AA5297","","K","1","Lindenhof","13","1301","Zürichberg","Altstadt","St.Peter u Paul","St.Peter","1","3","3","29.0","8.539764579706915","47.373115180353350","POINT (2683163.8 1247502.8)"

This is the command I'm trying to run:

    LOAD DATA INFILE '/home/coder/project/geoz.adrstzh_adressen_stzh_p.csv'
INTO TABLE mainZuerichAddresses
FIELDS
    TERMINATED BY ','
    OPTIONALLY ENCLOSED BY '"'
    ESCAPED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS
(@col1,@dummy,@col3,@col4,@dummy,@col6,@col7,@dummy,@dummy,@col10,@dummy,@dummy,@dummy,@col14,@dummy,@col16,@dummy,@dummy,@dummy,@col20,@col21,@dummy,@col23,@col24,@col25,@col26,@col27,@col28,@col29,@dummy,@dummy,@dummy,@dummy,@col34) 
SET objid=@col29,gebaeudeeingangnummer=@col1,adresse=@col6,lokalisationsname=@col3,
    hausnummer=@col4,plz=@col14,plz_ortschaft=@col16,stadtkreis=@col20,
    gebaeudenummer=@col10,statistisches_quartier=@col21,status=@col7,statistische_zone=@col23,schulkreis=@col24,verwaltungsquartier=@col25,
    roem_kath_kirchgemeinde=@col26,ev_ref_kirchgemeinde=@col27,ev_ref_kirchenkreis=@col28,geometry=@col34;
   

Here I added all the 34 columns from the csv file:

(@col1,@dummy,@col3,@col4,@dummy,@col6,@col7,@dummy,@dummy,@col10,@dummy,@dummy,@dummy,@col14,@dummy,@col16,@dummy,@dummy,@dummy,@col20,@col21,@dummy,@col23,@col24,@col25,@col26,@col27,@col28,@col29,@dummy,@dummy,@dummy,@dummy,@col34) 

and here I'm trying to add the data to the table columns I have, which are in a different order than the csv and I don't need all of them, only 18. (Can I even do that, cherry-pick columns from the csv file and mix their order?)

SET objid=@col29,gebaeudeeingangnummer=@col1,adresse=@col6,lokalisationsname=@col3,hausnummer=@col4,plz=@col14,plz_ortschaft=@col16,stadtkreis=@col20,gebaeudenummer=@col10,statistisches_quartier=@col21,status=@col7,statistische_zone=@col23,schulkreis=@col24,verwaltungsquartier=@col25,roem_kath_kirchgemeinde=@col26,ev_ref_kirchgemeinde=@col27,ev_ref_kirchenkreis=@col28,geometry=@col34;

But I'm keep getting this error:

ERROR 1366 (HY000): Incorrect integer value: 'Werdmühlestrasse 4' for column 'plz' at row 1

I read the documentation, but it's not very clear how the mysql should be formatted.:

You must also specify a column list if the order of the fields in the input file differs from the order of the columns in the table. Otherwise, MySQL cannot tell how to match input fields with table columns.

I based my mysql command on this question, but it's quite old.

I also found this question which gave some advice about FIELDS and LINES termination so I played around a bit with that.

I'm not sure if the csv formatting is the problem or the order I'm trying to load the data from the csv into the table colums.

Someone has an idea?

Answer 1

look carefully on error message. There says value: 'Werdmühlestrasse 4' is not integer.

Answer 2

There are a number of questions in your question for this part 'it's not very clear how the mysql should be formatted'

What appears in brackets defines the order of columns in the csv file and should include all columns for example

given a csv file

name,junk,val
mike,1234,aaa
bob,4567,bbb
steve,8910,ccc

and a table

create table t(id int auto_increment primary key, 
name varchar(20),
junk varchar(20),
val varchar(20));

The following will fail because I have not provided a column list in the csv file and load data infile attempts to load the first field in input file to id and the datatype does not match the datatype for id in the table.

LOAD DATA INFILE 'C:\\Program Files\\MariaDB 10.1\\data\\sandbox\\data.txt'
INTO TABLE t
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'  ESCAPED BY '"'
LINES TERMINATED BY '\r\n' IGNORE 1 ROWS;

in fact I want to allow auto increment so I specify the target columns for all the input file columns.

LOAD DATA INFILE 'C:\\Program Files\\MariaDB 10.1\\data\\sandbox\\data.txt'
INTO TABLE t
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'  ESCAPED BY '"'
LINES TERMINATED BY '\r\n' IGNORE 1 ROWS
(name,junk,val);

+----+-------+------+------+
| id | name  | junk | val  |
+----+-------+------+------+
|  1 | mike  | 1234 | aaa  |
|  2 | bob   | 4567 | bbb  |
|  3 | steve | 8910 | ccc  |
+----+-------+------+------+
3 rows in set (0.001 sec)

and if I want col3 in the file for go to name in table and col1 in file to go to val in table

LOAD DATA INFILE 'C:\\Program Files\\MariaDB 10.1\\data\\sandbox\\data.txt'
INTO TABLE t
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'  ESCAPED BY '"'
LINES TERMINATED BY '\r\n' IGNORE 1 ROWS
(val,junk,name);

+----+-------+------+-------+
| id | name  | junk | val   |
+----+-------+------+-------+
|  1 | mike  | 1234 | aaa   |
|  2 | bob   | 4567 | bbb   |
|  3 | steve | 8910 | ccc   |
|  4 | aaa   | 1234 | mike  |
|  5 | bbb   | 4567 | bob   |
|  6 | ccc   | 8910 | steve |
+----+-------+------+-------+
6 rows in set (0.001 sec)

and if I want to load a column from the input file park it in a user defined variable and do nothing with it (as you have done)

LOAD DATA INFILE 'C:\\Program Files\\MariaDB 10.1\\data\\sandbox\\data.txt'
INTO TABLE t
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'  ESCAPED BY '"'
LINES TERMINATED BY '\r\n' IGNORE 1 ROWS
(val,@dummy,name);

+----+-------+------+-------+
| id | name  | junk | val   |
+----+-------+------+-------+
|  1 | mike  | 1234 | aaa   |
|  2 | bob   | 4567 | bbb   |
|  3 | steve | 8910 | ccc   |
|  4 | aaa   | 1234 | mike  |
|  5 | bbb   | 4567 | bob   |
|  6 | ccc   | 8910 | steve |
|  7 | aaa   | NULL | mike  |
|  8 | bbb   | NULL | bob   |
|  9 | ccc   | NULL | steve |
+----+-------+------+-------+
9 rows in set (0.001 sec)

Another use for the user defined variables is for input processing see the manual for examples of this https://dev.mysql.com/doc/refman/8.0/en/load-data.html

in your case you aren't doing any input transformations so all those set statements appear to be unnecessary, but will work.
