Here is my query:
SELECT * FROM Auta WHERE SUBSTR(spz, 1, 2) =
(SELECT SUBSTR(spz, 1, 2) FROM Auta WHERE typ = 'BMW' AND specifikacia_typu = 'Z1' LIMIT 1);
And when I run it I get this error:
ORA-00907: missing right parenthesis
I'm getting a little desperate, I've already tried adding parentheses everywhere in the query and I still get the error? There are 3 left and 3 right parentheses in the query so everything should be all right.
The LIMIT clause doesn't exist in Oracle. Instead you would use rownum:
SELECT *
FROM Auta
WHERE SUBSTR(spz, 1, 2) = (SELECT SUBSTR(spz, 1, 2)
FROM Auta
WHERE typ = 'BMW'
AND specifikacia_typu = 'Z1'
AND ROWNUM = 1);
What's that "LIMIT 1" for? I don't believe that's correct Oracle syntax. If you're trying to limit the output to one row, use:
WHERE rownum = 1
LIMIT 1 is a MySQLism, as far as I know.
SELECT *
FROM Auta
WHERE SUBSTR(spz, 1, 2) =
(SELECT SUBSTR(spz, 1, 2)
FROM Auta
WHERE typ = 'BMW'
AND specifikacia_typu = 'Z1'
AND ROWNUM = 1);
...should give you the expected results

I FOUND MY MISTAKE!!! This is wrong CASE WHEN regexp_substr(artikel.abez1,'[^/]*$') AS download,
I just deleted 'Case when' and it works! Thank you everyone! :)
I have this data:
DE-Internet-LTE
AE-Internet-Ethernet-10M/30M
How can I get only the value "10M"? and if there's none, I want it to return to null.
I used this query:
regexp_substr(artikel.abez1,'[^-/]*$') AS upload
On the second row, it gives the result "10M" but on the first row it return to "LTE" instead of "null".
I'm using SQL Tool 1.8 b38.
UPDATE:
My full query:
`
SELECT DISTINCT artikel.artnr1, L1.lfnr1 AS lfnr, L1.name1 AS lf_name,
artikel.abez1, regexp_substr(artikel.abez1,'(.?){1}(.?)-', 1, 1, '',
2) AS land, regexp_substr(artikel.abez1,'(.?-){1}(.?)-', 1, 1, '',
2) AS Technologie, CASE WHEN
regexp_substr(artikel.abez1,'(.?-){2}(.?)-', 1, 1, '', 2) IS NULL
THEN regexp_substr(artikel.abez1,'[^-]$') ELSE
regexp_substr(artikel.abez1,'(.?-){2}(.?)-', 1, 1, '', 2) END AS
Topologie, regexp_substr(regexp_substr(artikel.abez1,
'([^-/]+)/[^-/]+$'), '^[^-/]+') AS upload, CASE WHEN

InStr(angaufgut.reserve1, '.') > 1 THEN Months_Between(
bestanfrage.anfragedatum, To_Date(angaufgut.reserve1)) ELSE
To_Number(angaufgut.reserve1) end AS Laufzeit FROM artikel inner join

LIKE 'ac%' AND Lower(abez1) NOT LIKE 'cust%' and artikel.mandant = 1
AND bestanfragepos.preis != 0 ORDER BY abez1 /
`
it gives error ora-00920 invalid relational operator.
It only worked on a single data when I used this:
SELECT regexp_substr(regexp_substr(artikelbez, '([^-/]+)/[^-/]+$'), '^[^-/]+') FROM nag_reporting_leitungspreise WHERE art = 'Vertrag' AND REF = 3791
Your code returns 30M. If you really want 10M, then this should do what you want:
select regexp_substr(regexp_substr(t.abez1, '([^-/]+)/[^-/]+$'), '^[^-/]+') AS upload
from t;
Here is a db<>fiddle.
with t(str) as (
select * from table(ku$_vcnt(
'DE-Internet-LTE',
'AE-Internet-Ethernet-10M/30M',
'AE-Internet-Ethernet-20m/40m',
'AE-Internet-Ethernet-300M/500M',
'AE-Internet-Ethernet-4000k/600k',
'AE-Internet-Ethernet-200M'
))
)
select
str,
regexp_substr(str, '(\d+(k|m))(/\d+(k|m))?',1,1,'i',1) upload,
regexp_substr(str, '/(\d+(k|m))',1,1,'i',1) download
from t;
Results:
STR UPLOAD DOWNLOAD
----------------------------------- ------- --------
DE-Internet-LTE
AE-Internet-Ethernet-10M/30M 10M 30M
AE-Internet-Ethernet-20m/40m 20m 40m

AE-Internet-Ethernet-4000k/600k 4000k 600k
AE-Internet-Ethernet-200M 200M
Just have a look at the below solution:
with t(str) as
(
select column_value
from table(sys.odcivarchar2list(
'DE-Internet-LTE',
'AE-Internet-Ethernet-10M/30M',
'AE-Internet-Ethernet-20m/40m',
'AE-Internet-Ethernet-300M/500M',
'AE-Internet-Ethernet-4000k/600k',
'AE-Internet-Ethernet-200M'
))
)
select str,
regexp_substr(str, '-(\d+.*?)(/|$)',1,1,null,1) as upload,
regexp_substr(str, '/(\d+.*?)$',1,1,null,1) as download,
regexp_substr(regexp_substr(str, '([^-/]+)/[^-/]+$'), '^[^-/]+') as Gordan_Linoff_upload
from t;

Use proper table aliases and IN clause instead of = for sub-queries.
SELECT DISTINCT (t1.FISCAL_QUARTER_START_DATE)
FROM TEST_STAGE.TEST_TABLE t1
WHERE t1.FISCAL_YEAR_ID IN (
SELECT t2.FISCAL_YEAR_ID
FROM TEST_STAGE.TEST_TABLE t2
WHERE t2.CALENDAR_DATE = FROM_UNIXTIME(UNIX_TIMESTAMP())
)
AND SUBSTR(t1.FISCAL_QUARTER_NAME, 0, 2) IN (
SELECT SUBSTR(t3.FISCAL_QUARTER_NAME, 0, 2)
FROM TEST_STAGE.TEST_TABLE t3
WHERE t3.CALENDAR_DATE = FROM_UNIXTIME(UNIX_TIMESTAMP())
);
I think your query is equivalent and could be converted to a single sub-query with EXISTS.
SELECT DISTINCT t1.FISCAL_QUARTER_START_DATE
FROM TEST_STAGE.TEST_TABLE t1
WHERE EXISTS (
SELECT 1
FROM TEST_STAGE.TEST_TABLE t2
WHERE SUBSTR(t1.FISCAL_QUARTER_NAME, 0, 2) = SUBSTR(t2.FISCAL_QUARTER_NAME, 0, 2)
AND t1.FISCAL_YEAR_ID = t2.FISCAL_YEAR_ID
AND t1.CALENDAR_DATE = FROM_UNIXTIME(UNIX_TIMESTAMP())

END;
When I convert this query to postgres having some changes like Ref_Cur to refcursor and NVL to Coalesce function. I am still unable to resolve the connect by syntax. Some people suggested to use CTE's but I am unable to get it. Any help guys?
Edit
For random googlers below is the answer to my above problem. Special thanks to MTO.
WHERE Ed.Site_Id = Es.Site_Id
AND Es.Subregion_Id = Esr.Subregion_Id
AND Esr.Region_Id = Er.Region_Id
AND Ed.Billing_Month_f = p_Billing_Month) data
Right Outer Join (Select 1 as Id union All
Select 2 as Id union All
Select 3 as Id union All
Select 4 as Id) all_value
On data.Amount_Sort = all_value.Id
GROUP BY all_value.Id
ORDER BY AVG(all_value.Id);
The "generation" of IDs can be simplified in Postgres.
either use a values() clause:
Right Outer Join ( values (1,2,3,4) ) as all_value(id) On data.Amount_Sort = all_value.Id
or, if those are always a consecutive numbers, use generate_series():
Right Outer Join generate_series(1,4) as all_value(id) On data.Amount_Sort = all_value.Id
Since your hierarchical query appears to be using static strings, you can convert this:
SELECT Regexp_Substr('1,2,3,4,', '[^,]+', 1, Rownum) Id
FROM Dual
CONNECT BY Rownum <= Length('1,2,3,4,') - Length(REPLACE('1,2,3,4,', ',')
To:
SELECT 1 AS id FROM DUAL UNION ALL
SELECT 2 FROM DUAL UNION ALL
SELECT 3 FROM DUAL UNION ALL
SELECT 4 FROM DUAL
Which should then be simpler to convert to PostgreSQL.

You can use the ROWNUM. Oracle applies rownum to the result after it has been returned.
You need to filter the result after it has been returned, so a subquery is required. You can also use RANK() function to get Top-N results.
SELECT
*
FROM
(
SELECT
ts.tablespace_name AS TBNAME,
round((ts.tablespace_size/1024/1024),2) AS SIZE_MB,
round((ts.tablespace_used_size/1024/1024),2) AS USED_MB,
round(((ts.tablespace_size - ts.tablespace_used_size)/1024/1024),2) AS FREE_MB
FROM
mgmt$db_tablespaces ts,
(SELECT d.target_guid, d.tablespace_name, count(d.file_name) df_count,
sum(decode(d.autoextensible, 'YES', 1, 0)) auto_extend
FROM mgmt$db_datafiles d, mgmt$target t
WHERE t.target_guid = '<id>' AND

I have a sql statement like below. How can I add a single row(code = 0, desc = 1) to result of this sql statement without using union keyword? thanks.
select code, desc
from material
where material.ExpireDate ='2010/07/23'
You can always create a view for your table which itself uses UNION keyword
CREATE VIEW material_view AS SELECT code, desc, ExpireDate FROM material UNION SELECT '0', '1', NULL;
SELECT code, desc FROM material_view WHERE ExpireDate = '2010/07/23' OR code = '0';
WITH material AS
(
SELECT *
FROM
(VALUES (2, 'x', '2010/07/23'),
(3, 'y', '2009/01/01'),
(4, 'z', '2010/07/23')) vals (code, [desc], ExpireDate)
)
SELECT
COALESCE(m.code,x.code) AS code,
COALESCE(m.[desc],x.[desc]) AS [desc]
FROM material m
FULL OUTER JOIN (SELECT 0 AS code, '1' AS [desc] ) x ON 1=0
WHERE m.code IS NULL OR m.ExpireDate ='2010/07/23'
Gives
code desc
----------- ----
2 x
4 z
0 1
Since you don't want to use either a union or a view, I'd suggest adding a dummy row to the material table (with code = 0, desc = 1, and ExpireDate something that would never normally be selected - eg. 01 January 1900) - then use a query like the following:
select code, desc
from material
where material.ExpireDate ='2010/07/23' or
material.ExpireDate ='1900/01/01'
Normally, a Union would be my preferred option.
