Hi all, I've lost a significant time trying to get data from mysql database into monetdb. Since I have a lot of data, I wanted to make it as fast and automated as possible, but to no avail. There are several issues I encountered, and I'd appreciate any help on any of them. I'm running the latest monetDB on CentOS: % mclient --version mclient, the MonetDB interactive terminal (Jul2015-SP4) support for command-line editing compiled-in character encoding: UTF-8 1. I tried following the last example on https://www.monetdb.org/Documentation/SQLreference/Permissions in order to get another user to be able to perform COPY INTO, but it fails: % mclient -u monetdb -d some_db password: Welcome to mclient, the MonetDB/SQL interactive terminal (Jul2015-SP4) Database: MonetDB v11.21.19 (Jul2015-SP4), 'mapi:monetdb://internal:50000/some_db' Type \q to quit, \? for a list of available commands auto commit mode: on sql>GRANT COPY FROM TO copy_role; syntax error, unexpected COPY in: "grant copy" 2.

Hi all,

I've lost a significant time trying to get data from mysql database into monetdb. Since I have a lot of data, I wanted to make it as fast and automated as possible, but to no avail.

There are several issues I encountered, and I'd appreciate any help on any of them. I'm running the latest monetDB on CentOS: % mclient --version mclient, the MonetDB interactive terminal (Jul2015-SP4) support for command-line editing compiled-in character encoding: UTF-8

1. I tried following the last example on https://www.monetdb.org/Documentation/SQLreference/Permissions in order to get another user to be able to perform COPY INTO, but it fails:

% mclient -u monetdb -d some_db password: Welcome to mclient, the MonetDB/SQL interactive terminal (Jul2015-SP4) Database: MonetDB v11.21.19 (Jul2015-SP4), 'mapi:monetdb://internal:50000/some_db' Type \q to quit, \? for a list of available commands auto commit mode: on sql>GRANT COPY FROM TO copy_role; syntax error, unexpected COPY in: "grant copy"

2. Ok, since I can't run COPY INTO FROM FILE, I decided to go with FROM STDIN version. To do so, I dump the mysql database and import that in monetdb. That also fails:

% mysql -N -B -u reader -pxxx some_db -h some_host -e "SELECT * FROM errortable;"|mclient -d some_db -s "COPY 15 RECORDS INTO errortable FROM STDIN USING DELIMITERS '\t','\n','\'';" - Failed to import table Column value 1 missing syntax error, unexpected sqlINT in: "100"

% mclient -u writer -d some_db password: Welcome to mclient, the MonetDB/SQL interactive terminal (Jul2015-SP4) Database: MonetDB v11.21.19 (Jul2015-SP4), 'mapi:monetdb://internal:50000/some_db' Type \q to quit, \? for a list of available commands auto commit mode: on sql>\d errortable CREATE TABLE "some_db"."errortable" ( "rejectreason" INTEGER NOT NULL, "text" CHARACTER LARGE OBJECT );

Another try also fails (still using STDIN):

% mysql -N -B -u reader -pxxx some_db -h some_host -e "SELECT * FROM errortable;" >test.out % mclient -d some_db -s "COPY 15 RECORDS INTO errortable FROM STDIN USING DELIMITERS '\t','\n','\'';"
(note different error messages, and also note that 100 is a perfectly good sqlINT)

If I try the following, this succeeds. However, this is something I'm trying to avoid, as I'd had to create huge files (100+GB), which is an absolute waste of space and time.

% mysql -N -B -u reader -pxxx some_db -h some_host -e "SELECT * FROM errortable;" >test.out % mclient -d some_db -s "COPY 15 RECORDS INTO errortable FROM '/home/nikola/test.out' USING DELIMITERS '\t','\n','\'';" COPY INTO: insufficient privileges: COPY INTO from file(s) requires database administrator rights, use 'COPY INTO "errortable" FROM STDIN' instead # obviously, fails due to (1)

Hi

Did you try the 'best effort' approach, which should give you possible more insights in what is wrong with the file.

See sql test directory for hint:

create table t_int(i int);

-- If a numeric is enclosed as string we have to be careful -- It seems that convention is to check for it, turning -- the example below into one null value added to the table. copy 1 records into t_int from stdin USING DELIMITERS ',','\n','\"' NULL AS '' best effort; ""

select * from t_int; select * from sys.rejects; call sys.clearrejects(); delete from t_int;

-- A decimal value entered at a place where we expect an int -- should be recognized. It is the residu of dumping an int -- as decimal. copy 2 records into t_int from stdin USING DELIMITERS ',','\n','\"' NULL AS '' best effort; 3.00 -4.0000

% mclient -u monetdb -d some_db password: Welcome to mclient, the MonetDB/SQL interactive terminal (Jul2015-SP4) Database: MonetDB v11.21.19 (Jul2015-SP4), 'mapi:monetdb://internal:50000/some_db' Type \q to quit, \? for a list of available commands auto commit mode: on sql>GRANT COPY FROM TO copy_role; syntax error, unexpected COPY in: "grant copy"

2. Ok, since I can't run COPY INTO FROM FILE, I decided to go with FROM STDIN version. To do so, I dump the mysql database and import that in monetdb. That also fails:

% mysql -N -B -u reader -pxxx some_db -h some_host -e "SELECT * FROM errortable;"|mclient -d some_db -s "COPY 15 RECORDS INTO errortable FROM STDIN USING DELIMITERS '\t','\n','\'';" - Failed to import table Column value 1 missing syntax error, unexpected sqlINT in: "100"

Another try also fails (still using STDIN):

(note different error messages, and also note that 100 is a perfectly good sqlINT)

If I try the following, this succeeds. However, this is something I'm trying to avoid, as I'd had to create huge files (100+GB), which is an absolute waste of space and time.

% mysql -N -B -u reader -pxxx some_db -h some_host -e "SELECT * FROM errortable;" >test.out % mclient -d some_db -s "COPY 15 RECORDS INTO errortable FROM '/home/nikola/test.out' USING DELIMITERS '\t','\n','\'';" COPY INTO: insufficient privileges: COPY INTO from file(s) requires database administrator rights, use 'COPY INTO "errortable" FROM STDIN' instead # obviously, fails due to (1)

Hi Niels, thanks for the pointer. I'm pretty sure I installed the latest thing from yum, so I went to repeat the process. Also, is Jun2016 some next release? (as we're still in April). If so, it would be great if documentation would mention which version it applies to (it now says "In the feature release following Jul2015", which for me is Jul2015-SP4). BTW, if I follow the steps from: http://dev.monetdb.org/downloads/epel/ it fails after % yum install http://dev.monetdb.org/downloads/epel/MonetDB-release-epel-1.1-1.monetdb.noa... % yum update http://dev.monetdb.org/downloads/epel/7.2/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found because monetdb.repo has $releasever , which is 7.2 on my system, and server only exposes /7/.

Hi, one question I have is why you specify that your string delimiter is a single quote, while your data does not seem to have any string delimiters? As for the granting of premissions, you might want to file a bug report; either the documentation of the implementation is wrong, or at least they do not match or are misleading. (well, I assume you you replaced "copy_role" by the actual role's name that you want to grant the permission to, right?)

Hi Stefan, thanks for your help, removing ';' helped. I'm now struggling to load 100+ million of rows via COPY INTO FROM STDIN, but it just fails (no error printed, apart from "0 affected rows"). 10-20 mil rows is ok to load via this method, and I'll see if I can make something that could split up the input into chunks and feed it into mclient. Cheers, Nikola

Hi,

one question I have is why you specify that your string delimiter is a single quote, while your data does not seem to have any string delimiters?

As for the granting of premissions, you might want to file a bug report; either the documentation of the implementation is wrong, or at least they do not match or are misleading. (well, I assume you you replaced "copy_role" by the actual role's name that you want to grant the permission to, right?)

Best, Stefan

Hi all,

I've lost a significant time trying to get data from mysql database into monetdb. Since I have a lot of data, I wanted to make it as fast and automated as possible, but to no avail.

There are several issues I encountered, and I'd appreciate any help on any of them. I'm running the latest monetDB on CentOS: % mclient --version mclient, the MonetDB interactive terminal (Jul2015-SP4) support for command-line editing compiled-in character encoding: UTF-8

1. I tried following the last example on https://www.monetdb.org/Documentation/SQLreference/Permissions in order to get another user to be able to perform COPY INTO, but it fails:

% mclient -u monetdb -d some_db password: Welcome to mclient, the MonetDB/SQL interactive terminal (Jul2015-SP4) Database: MonetDB v11.21.19 (Jul2015-SP4), 'mapi:monetdb://internal:50000/some_db' Type \q to quit, \? for a list of available commands auto commit mode: on sql>GRANT COPY FROM TO copy_role; syntax error, unexpected COPY in: "grant copy"

2. Ok, since I can't run COPY INTO FROM FILE, I decided to go with FROM STDIN version. To do so, I dump the mysql database and import that in monetdb. That also fails:

% mysql -N -B -u reader -pxxx some_db -h some_host -e "SELECT * FROM errortable;"|mclient -d some_db -s "COPY 15 RECORDS INTO errortable FROM STDIN USING DELIMITERS '\t','\n','\'';" - Failed to import table Column value 1 missing syntax error, unexpected sqlINT in: "100"

Nikola, You might want to look at Pentaho Data Integration, I've had good success using it to bulk load MonetDB. You can also "loop" within it so you could chunk the dataset. Bryan On Fri, Apr 15, 2016 at 11:36 AM, Knezevic Nikola wrote:
