I have written code like this in PostgreSQL. But I'm getting error for ROWNUM
EXECUTE 'SELECT BENMASTDTL_BEN_CODE FROM BENMASTDTL WHERE BENMASTDTL_ENTITY_CODE =$1 AND BENMASTDTL_CUSTOMER_CODE =$2 AND
BENMASTDTL_ACCOUNT_NUMBER =$3 AND BENMASTDTL_IFSC=$4 AND ROWNUM=1'
INTO STRICT W_BENMASTDTL_BEN_CODE
USING P_ENTITY_CODE, P_CUST_CODE, P_BEN_AC_NUM, P_BEN_IFSC;
error is like column "rownum" does not exist
please help me to solve this error
I have this query :
INSERT INTO lytnobjects.devices (id,idedge,uniqueref,constructeur,ipaddress,macaddress,
hostname,devicetype,isfirewall,isvisible,iscorporate,
ishub,osname,osversion,datecreation,lasttrafic,
hourtrafic,daytrafic,monthtrafic)
VALUES ('e1e455e98b6ed0037a58d0c1f5dc245a',3183,'TODO','TODO','192.168.143.49',
'b0:0c:d1:bb:36:1c','HPBB361C','Other',False,False,False,False,'','',
'2021-10-29T00:58:53.709','2021-01-01T00:00:00','0/0','0/0','0/0')
When I execute the query using python 3.9 and psycopg2_binary (PostgreSQL), I get an error :
unterminated quoted string at or near "'HPBB361C"
conn is the opened connection to the database (AWS RDS PostgreSQL)
sql is a string with the query above
def SQLExec(conn,sql):
try: cur = conn.cursor()
cur.execute(sql)
except (Exception, psycopg2.DatabaseError) as error:
print("***** ERROR:",error)
cur.close()
If I execute the same request from pgAdmin, I get no error !
There is no missing quote as you can see in the query, and no reason to point an error at this place!
So, I have a string (sql) with the query ("INSERT ...")
I call execute from psycopg2, and get an error: unterminated quoted string at or near "'HPBB361C"
I copy/paste the same string into pgAdmin, and the query is executed with no error
The same string (query)
Any idea why I get an error from my python app?
I am looking for an answer since many hours, but find no explanation, and I don't know how to fix the problem (which doesn't exist for me)
Your help is very appreciated
Thank you
I finaly found the answer!
I build the sql query (string) using some variables coming from various sources, like Amazon S3 for instance.
I assumed that the variable was really a string, with nothing "bizarre" in it... But in fact, sometimes, the "string" was ended with a "\x00" char, that is not displayed, so the string looks just normal :-/
When I execute my query (string) with psycopg2, it receives the extra \x00 char, which ends the string at this place! This is why it says there is a missing quote
I put a trace in the code to display the .encode() version of my string, and it revealed the \x00 at the end. So now I "clean" all string variables used in my queries, just with myvariable.replace("\x00","")
And it works now. There is probably a more conventional way to fix this...
I hope it may help somebody sometime! ;-)
I get this error when trying out this command in the BIRT Classic Models sample database in Data Studio
select xmlelement(name "custno", customers.customernumber) from customers
Syntax error: Encountered "\"custno\"" at line 1, column 24.
I do not know how to correct it.
Thanks.
I'm not familiar with db2, but according to this your statement looks quite alrigth (although I'd place an alias to name this field...)
But this
Syntax error: Encountered "\"custno\"" at line 1, column 24.
seems to be a quite clear hint, that your error is connected to the NAME of the element.
I'm pretty sure, that this statement was created on string level.
Did you try to escape the "-characters with \"?
The SQL reaching the engine might look like
select xmlelement(name \"custno\", customers.customernumber) from customers
or
select xmlelement(name "\"custno"\", customers.customernumber) from customers
... which is wrong of course...
But to be honest: just guessing...
I am trying to save the result of a query into a variable. I am using IBM DB2, but I can only store the result if I am declaring the variable inside a procedure.
My code is:
DECLARE #myvar INTEGER;
SET #myvar = (SELECT MAX(ID) FROM S0SCSQMS.S0SRPTCNAME);
and I receive the following errors:
For the first line:"SQL0104N An unexpected token "INTEGER" was found following "DECLARE #myvar ". Expected tokens may include: "END-OF-STATEMENT". LINE NUMBER=1. SQLSTATE=42601"
The error code does not tell me much. I looked for it on the IBM documentation.
Looking forward for an answer.
Thank you.
try this (work on iseries db2 v7r1)
CREATE OR REPLACE VARIABLE myvar INTEGER ;
SET myvar = (SELECT max( id_xp_dossier) FROM cilgprod.xp_dossier);
DROP VARIABLE myvar;
I've been having trouble with eloquent that keeps returning error. Below is the query that i tried to run in laravel.
$actives = ProjectVersion::join('version_employees as ve', 've.report_id' ,'=', 'project_versions.id')
->join('employees as e', 've.employee_id', '=', 'e.id')
->whereBetween(\DB::raw("'1985-05-27'::date"),[
\DB::raw("to_date(timeline->>'start_time', 'YYYY-MM-DD')"),
\DB::raw("to_date(timeline->>'release_time', 'YYYY-MM-DD')")])
->groupBy('e.name')
->select(\DB::raw('count(e.id), e.name'))
->get();
Now this returns an error of
Invalid datetime format: 7 ERROR: invalid input syntax for type date: "to_date(timeline->>'start_time', 'YYYY-MM-DD')"
The full query returned by the error message is
SELECT count(e.id), e.name
FROM "project_versions" inner join "version_employees" as "ve" on "ve"."report_id" = "project_versions"."id" inner join "employees" as "e" on "ve"."employee_id" = "e"."id"
WHERE '1985-05-27'::date
BETWEEN to_date(timeline->>'start_time', 'YYYY-MM-DD')
AND to_date(timeline->>'release_time', 'YYYY-MM-DD')
GROUP BY "e"."name"
The thing is that when i run this query in pgadmin, it runs fine and returns the result that i wants.
I've been stuck for hours debugging this. Any idea on where the problem is ?
Well first off, it's not really eloquent in the way you're using it with all those Raw statements ;-)
Try using the Carbon class: Carbon::now()->toDateString() will return a date in the Y-m-d format.
For the where clause, if I'm understanding your query correctly, you can use 2 where clauses instead of the whereBetween with Raw SQL: ->where('start_time', '>', $start_time_preprocessed_by_carbon)->where('release_time', '<', $release_time_preprocessed_by_carbon)
And you seem to want the count which means you can end with a ->count() instead of a ->get()
I'd love to give you the full query but couldn't decipher it completely. However these implementations should give you a nudge in the right direction! They will help you abstract your query further to the point that Laravel's internal query generator will translate the code into the correct syntax for your database!
