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)

Database-migration ms sql to postgresql

I am getting a syntax error when converting between SQL Server to PostgreSQL. Any thoughts?
IF (var_port_with_bmrk_total_mv != 0 AND var_bmrk_info IS NOT NULL) THEN
BEGIN
insert into t$tmp_diff
select #asof_dt asof_dt,#choiceID choiceID ,p.input_array_type ,p.group_order, CONVERT(DECIMAL(32,10),p.port_value/#var_port_total_mv) port_value,convert(decimal(32,10), isnull(bmrk_value/#port_with_bmrk_total_mv,0)) bmrk_value
from t$tmp_port_sum p, t$tmp_bmrk_sum b

END;
ELSE
Original before conversion
insert into #tmp_other_diff
select #asof_dt asof_dt,#choiceID choiceID , b.input_array_type,b.grouping,convert(decimal(32,10),0) port_value, (bmrk_value/#port_with_bmrk_total_mv) bmrk_value
from #tmp_bmrk_other_sum b

Error message:
Error occurred during SQL query execution
Reason:
SQL Error [42601]: ERROR: syntax error at or near ","
Position: 9030
the relevant comma being:
CONVERT(DECIMAL(32,10),p.port_value

There is no convert() function in Postgres. Use the SQL standard cast or the Postgres extension ::data type. In this case:
...., cast(0 as decimal(30,10)) port_value, ....
OR
...., 0::decimal(30,10) port_value, ...
Note: No comma after the expression. In the original port_value is the column alias. You need to keep it that way.

ERROR: Teradata prepare: Syntax error when usign date format 'ddmmyyy'd in SAS

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

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 (

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'

It can't calculate count(*) in a query onto DB2 database

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

PostgreSQL: Why does this join query throw a syntax error

I don't understand, why the following query produced an error. Whereas in other dbms (eg mysql) this sort of query is absolutely legal.
ERROR: Syntax error at the end of input
LINE 1: SELECT * FROM "addr_country" AS c JOIN "addr_state" AS s
^
SQL state: 42601
Character: 59
Adding an on-clause to the query makes it working:
SELECT * FROM "addr_country" AS c JOIN "addr_state" AS s
ON c."id" = s."country" AND s.id = 10

Due to this answer, MySQL makes a cross join out of a join w/o conditions

Hive FAILED: Parse Exception line 3:39 mismatched input

Im trying to make a query that will check if there is any row which has a salary that is 10000 higher than the salary for that department but when I try to run it I get this Error:
FAILED: ParseException line 3:39 mismatched input 'SELECT' expecting ) near '''' in expression specification
this is the query Im using
set AVERAGES ='SELECT ROLE, AVG(AnnualSalary) From Salaries GROUP BY ROLE';
SELECT ROLE, AVG(AnnualSalary) FROM Salaries
GROUP BY ROLE, AnnualSalary HAVING AnnualSalary > ('${hiveconf:AVERAGES}' + 10000);

Currently Hive does not support storing the query result into variable.
You can use window function to achieve this.
select * from
( select *,
avg(AnnualSalary) over(partition by ROLE) role_avg
from
Salaries
) a
where
AnnualSalary > role_avg+10000
