Can you tell me why this is throwing an error in Redshift?
WITH Testing_PADDING AS (SELECT '12345678' AS column1)
SELECT LPAD(column1, 9,'0') FROM Testing_PADDING;
Here is the error I receive:
"Invalid operation: failed to find conversion function from "unknown" to text;"
Redshift can't determine data type from the context, so you need to explicitly set it
WITH Testing_PADDING AS (SELECT '12345678'::text AS column1)
SELECT
LPAD(column1, 9, '0')
FROM Testing_PADDING;
I suspect that one of your strings isn't being seen as text - likely the column1 text. (Sorry don't have a cluster up not to test)
Try:
WITH Testing_PADDING AS (SELECT '12345678'::text AS column1)
SELECT LPAD(column1, 9,'0'::text) FROM Testing_PADDING;

I'm using this code to extract information from this database. However, it is showing me this error:
ERROR: Teradata prepare: Syntax error, expected something like ')' between a string or a Unicode character literal and the word

from klarmxpw_her.vmher101 as t1 inner join vmher102ult as t2 on t1.cod_cte=t2.cod_cte and
t1.fec_consulta=t2.max_fec_consulta.
The code I'm using for this pass through is the following:
proc sql;

create table vmher101_m as
select * from connection to tera (

inner join vmher102ult as t2
on t1.cod_cte=t2.cod_cte and t1.fec_consulta=t2.max_fec_consulta);

Does anybody know what can I do?
You need to use TERADATA code inside the () after from connection to tera.

I want to do a count(*) of the number of a rows fom a DB2 database.
The basic query is the following:
select
SUBSTR("Request_Detail",LOCATE('/',"Request_Detail")+1,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)-LOCATE('/',"Request_Detail"))
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
Now I'd like to do a count(*) of the resulting rows, but if I do a query like this:
select
count(*),
SUBSTR("Request_Detail",LOCATE('/',"Request_Detail")+1,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)-LOCATE('/',"Request_Detail"))
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
It gives the error:
18:51:58 FAILED [SELECT - 0 rows, 0.032 secs] 1) [Code: -119, SQL State: 42803] An expression starting with "Request_Detail" specified in a SELECT clause, HAVING clause, or ORDER BY clause is not specified in the GROUP BY clause or it is in a SELECT clause, HAVING clause, or ORDER BY clause with a column function and no GROUP BY clause is specified.. SQLCODE=-119, SQLSTATE=42803, DRIVER=4.22.29
2) [Code: -727, SQL State: 56098] An error occurred during implicit system action type "2". Information returned for the error includes SQLCODE "-119", SQLSTATE "42803" and message tokens "Request_Detail".. SQLCODE=-727, SQLSTATE=56098, DRIVER=4.22.29
How could I do to get the count of the rows?
Which Request_Detail line's substr would you think it shows after the count?
If you count the lines, the result set will be a single line, and using any columns in it makes no sense.
If you want multiple lines, with a count for each found substr, you need to GROUP BY this substr.
This may work...
select
count(
SUBSTR("Request_Detail"
,LOCATE('/',"Request_Detail")+1
,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)
-LOCATE('/',"Request_Detail")))
)
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
But if not this should..
with cte as (
select
SUBSTR("Request_Detail"
,LOCATE('/',"Request_Detail")+1
,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)
-LOCATE('/',"Request_Detail"))) as mydetail
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
)
select count(*) from cte
I suggest you use REGEXP_EXTRACT to pick what you want out of your "Request_Detail" column. This is more flexable than using SUBSTR and LOCATE, and will avoid the statement was not executed because a numeric argument of a scalar function is out of range.. error
e.g
select
REGEXP_EXTRACT("Request_Detail",'.*/(.+/)',1,1,'',1)
, SUBSTR("Request_Detail",LOCATE('/',"Request_Detail")+1,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)-LOCATE('/',"Request_Detail"))
FROM TABLE(VALUES('aaaa/bbbb/ccc')) AS T("Request_Detail")
returns
1 |2
------|-----
bbbb/ |bbbb/
so, you could then do this
SELECT
COUNT(*)
, REGEXP_EXTRACT("Request_Detail",'.*/(.+/)',1,1,'',1)
FROM
"Request_Analisys"
GROUP BY
REGEXP_EXTRACT("Request_Detail",'.*/(.+/)',1,1,'',1)
for example
The full error message is:

The query I'm using is:

And the shared.sample function I'm using is:
CREATE OR REPLACE FUNCTION shared.sample(ids bigint[], size integer, seed integer DEFAULT 1, with_replacement boolean DEFAULT false, probabilities numeric[] DEFAULT NULL::numeric[])
RETURNS integer[] AS
$BODY$
set.seed(seed)

}
return(s)
$BODY$

COST 100;
ALTER FUNCTION shared.sample(bigint[], integer, integer, boolean, numeric[])
OWNER TO "server-superusers";
I'm pretty new to this stuff, so any help would be appreciated.
Not a problem of the function. Like the error messages says: The string '1e+06' cannot be cast to integer.
Obviously, the columns n_agents in your table results_20161109.initial_agent_count_by_tract_res_11 is not an integer column. Probably type text or varchar? (That info would help in your question.)
Either way, the assignment cast does not work for the target type integer. But it does for numeric:
Does not work:
SELECT '1e+06'::text::int; -- error as in question
Works:
SELECT '1e+06'::text::numeric::int;
If my assumptions hold, you can use this as stepping stone.
Replace b.n_agents in your query with b.n_agents::numeric::int.
It's your responsibility that numbers stay in integer range, or you get the next exception.
If that did not nail it, you need to look into function overloading:
Is there a way to disable function overloading in Postgres
And function type resolution:
PostgreSQL function call
The schema search path is relevant in many related cases, but you did schema-qualify all objects, so we can rule that out.
How does the search_path influence identifier resolution and the "current schema"
Your query generally looks good. I had a look and only found minor improvements:

, b.year
, s.pgid
FROM (
SELECT tract_id_alias

AND bldg_count_res > 0
ORDER BY pgid -- sort once in a subquery. cheaper.
) sub
GROUP BY 1

I am trying to run a hive query using COALESCE function to create a view. But it is throwing error like
cannot recognize input near '(' 'SELECT' 'realvalue' in expression specification
The query is given below. Please help and mention what is wrong in this.
CREATE VIEW IF NOT EXISTS exampledb.`ara_service` AS
SELECT T1.EntityId, T1.entityname AS EntityName,
T1.`xxx`,
T1.`yyy`,
COALESCE (T1.`aaa`, (SELECT `realvalue` FROM exampledb.`aba_service`
WHERE `id` = '333')) AS `CombinedValue`,
T1.`ddd`,
T1.`jjj`,
etc..
Please help. The error is in the usage of the select statement inside COALESCE .
NoViableAltException(231#[435:1: precedenceEqualExpression : ( ( LPAREN precedenceBitwiseOrExpression COMMA )=> precedenceEqualExpressionMutiple | precedenceEqualExpressionSingle );])
Thanks
if all you need is a default value, you could do
CREATE VIEW IF NOT EXISTS exampledb.`ara_service` AS
SELECT T1.EntityId, T1.entityname AS EntityName,
T1.`xxx`,
T1.`yyy`,
COALESCE (T1.`aaa`, def.`realvalue` ) AS `CombinedValue`,
T1.`ddd`,
T1.`jjj`,
FROM your_table T1
CROSS JOIN (
SELECT `realvalue`
FROM exampledb.`aba_service` WHERE `id` = '333') def
i am trying to get values from database by using following query

GROUP BY org.name,sto.ad_org_id,pro.name
ORDER BY org.name, pro.name;
after creating this i also created a class to call this query and get data but when i deploy my project i am getting following error
WARN - SQL Command failed with: ERROR: operator does not exist: character varying !
Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.
please help to solve this issue.
i finally found the mistake what i made.
the problem in the above query is i'm trying to make type cast of null value
now i changed the condition to check 'is not null' than "not like ''"
and even i don't need to add cast operation it's useless.
anyways thanks for you response. :)
