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
'd'. SQL statement was: WITH vmher102ult as ( select cod_cte, max(fec_consulta) as max_fec_consulta from
klarmxpw_her.vmher102 where cod_cte not in ('','0','00000000') and fec_consulta>='01MAR2021'd group by cod_cte) select t1.*
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;
connect to teradata as tera (user=&tuser. password=&tpass. server='TDMX03');
create table vmher101_m as
select * from connection to tera (
WITH vmher102ult as (

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);
disconnect from ter;
Does anybody know what can I do?
You need to use TERADATA code inside the () after from connection to tera.
Try
and fec_consulta>= DATE '2021-03-01'

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 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)

Problem: to_char() returns text and it sorts by text and not by date. So the output is jumbled rather than sorted by Mon-YY.
Do the aggregation in a derived table (aka "sub-query") that preserves the data type, then do the sorting in the outer query:
select to_char(ap_month, 'Mon-YY') as appl_month
appl_count,
fa_count
from (
select date_trunc('month', application_date) as ap_month,
count(distinct application_id) as appl_count,
sum(final_approval_ind) as fa_count,
from my_schema.my_table
group by ap_month
) t
order by ap_month;
date_trunc('month', application_date) will normalize the application_date to the start of the month, but will retain the date data type, so that the sorting in the outer query works correctly.
I have no idea what the dynamic SQL in your question is supposed to do, but if you need to use that query for whatever reasons as dynamic SQL, you need to escape the single quotes by doubling them.
execute '
select to_char(ap_month, ''Mon-YY'') as appl_month
appl_count,
fa_count
from (
select date_trunc(''month'', application_date) as ap_month,
count(distinct application_id) as appl_count,
sum(final_approval_ind) as fa_count,
from my_schema.my_table
group by ap_month
) t
order by ap_month;
'; -- end of dynamic SQL
But using Postgres' dollar quoting would be easier:
execute $dyn$
select to_char(ap_month, 'Mon-YY') as appl_month
appl_count,
fa_count
from (
select date_trunc('month', application_date) as ap_month,
count(distinct application_id) as appl_count,
sum(final_approval_ind) as fa_count,
from my_schema.my_table
group by ap_month
) t
order by ap_month;
$dyn$; -- end of dynamic SQL
Note that you can nest dollar quoted strings, so if that query is used inside a function, just use a different delimiter than you use for the function body (see the example in the manual)
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 have a database in postgreSQL. I want to read some data from there, but I get an error (column anganridref does not exist) when I execute my command.
Here is my NpgsqlCommand:
cmd.CommandText = "select * from angebot,angebotstatus,anrede where anrid=anganridref and anstaid=anganstaidref";
and my 3 tables
the names of my columns are rights. So I don't understand why that error comes. Someone can explain me why it does crash? Its not the problem of large and lowercase.
You are not prefixing your column names in the where clause:
select *
from angebot,
angebotstatus,
anrede
where anrid = anganridref <-- missing tablenames for the columns
and anstaid = anganstaidre
It's also recommended to use an explicit JOIN instead of the old SQL 89 implicit join syntax:
select *
from angebot
join angebotstatus on angebot.aaaa = angebotstatus.bbbb
join anrede on angebot.aaaa = anrede.bbbb
