I am trying to sort one column which have alphanumeric letters
see my query below
SELECT d.number
FROM table name d, table_name 2 a WHERE d.case_id ='11-41'
AND d.ExhibitTypeId = TypeId AND d.ComplianceNo = '0' and
active = 1 and number is not null order by case
when ISNUMERIC(d.number) = 1 then right('0000000000'+d.number+'0',10)
else right('0000000000'+d.number,10)
end
This is the output
1
2
3
11
12
2A1
I want this output instead
1
2
2A1
3
11
12
Any help regarding this is greatly appreciated.
If(ISNUMERIC(LEFT(case,2)
BEGIN
order by case
END
else
BEGIN
order by LEFT(case,1), LEFT(case,2)
END
Assuming SQL Server this may work with some tweaks
SELECT
d.number
FROM
table name d,
table_name 2 a
WHERE
d.case_id ='11-41'
AND
d.ExhibitTypeId = TypeId
AND
d.ComplianceNo = '0'
and
active = 1
and number is not null
order by
Convert(int, LEFT(number, Case
When PATINDEX('%[^0-9]%', number) > 0 Then PATINDEX('%[^0-9]%', number) - 1
Else LEN(number)
End)
),
LEN(Number)

I am pretty new to postgresql (or sql), and have not learned how to deal with such "within group" operation. My data is like this:
p_id number
97313 4
97315 10
97315 10
97325 0
97325 15
97326 4
97335 0
97338 0
97338 1
97338 2
97344 5
97345 14
97349 0
97349 5
p_id is not unique and can be viewed as a grouping variable. I would like to change the number within each p_id to achieve such operation:
if for a given p_id, one of the value is 0, but any of the other "number" for that pid is >2, then set the 0 value as NULL. Like the "p_id" 97325, there are "0" and "15" associated with it. I will replace the 0 by NULL, and keep the other 15 unchanged.
But for p_id 97338, the three rows associated with it have number "0" "1" "2", therefore I do not replace the 0 by NULL.
The final data should be like:
p_id number
97313 4
97315 10
97315 10
97325 NULL
97325 15
97326 4
97335 0
97338 0
97338 1
97338 2
97344 5
97345 14
97349 NULL
97349 5
Thank you very much for the help!
A CASE in a COUNT OVER in a CASE:
SELECT
p_id,
(CASE
WHEN number = 0 AND COUNT(CASE WHEN number > 2 THEN number END) OVER (PARTITION BY p_id) > 0
THEN NULL
ELSE number
END) AS number
FROM yourtable
Test it here on rextester.
Works for PostgreSQL 10:
SELECT p_id, CASE WHEN number = 0 AND maxnum > 2 AND counts >= 2 THEN NULL ELSE number END AS number
FROM
(
SELECT a.p_id AS p_id, a.number AS number, b.maxnum AS maxnum, b.counts AS counts
FROM trans a
LEFT JOIN
(
SELECT p_id, MAX(number) AS maxnum, COUNT(1) AS counts
FROM trans
GROUP BY p_id
) b
ON a.p_id = b.p_id
) a1
use case when
select p_id,
case when p_id>2 and number=0 then null else number end as number
from yourtable
http://sqlfiddle.com/#!17/898c3/1
I would express this as:
SELECT p_id,
(CASE WHEN number <> 0 OR MAX(number) OVER (PARTITION BY p_id) <= 2
THEN number
END) as number
FROM t;
If the fate of a record depends on the existence of other records within (the same or another) table, you could use EXISTS(...) :
UPDATE ztable zt
SET number = NULL
WHERE zt.number = 0
AND EXISTS ( SELECT *
FROM ztable x
WHERE x.p_id = zt.p_id
AND x.number > 2
);
Hey guys I have the below sample data which i want to query for.
MemberID AGEQ1 AGEQ2 AGEQ2
-----------------------------------------------------------------
1217 2 null null
58458 3 2 null
58459 null null null
58457 null 5 null
299576 6 5 7
What i need to do is to lookup the table and if any AGEx COLUMN contains any data then it counts the number of times there is data for that row in each column
Results example:
for memberID 1217 the count would be 1
for memberID 58458 the count would be 2
for memberID 58459 the count would be 0 or null
for memberID 58457 the count would be 1
for memberID 299576 the count would be 3
This is how it should look like in SQL if i query the entire table
1 Children - 2
2 Children - 1
3 Children - 1
0 Children - 1
So far i have been doing it using the following query which isnt very efficient and does give incorrect tallies as there are multiple combinations that people can answer the AGE question. Also i have to write multiple queries and change the is null to is not null depending on how many children i am looking to count a person has
select COUNT (*) as '1 Children' from Member
where AGEQ1 is not null
and AGEQ2 is null
and AGEQ3 is null
The above query only gives me an answer of 1 but i want to be able to count the other columns for data as well
Hope this is nice and clear and thank you in advance
If all of the columns are integers, you can take advantage of integer math - dividing the column by itself will yield 1, unless the value is NULL, in which case COALESCE can convert the resulting NULL to 0.
SELECT
MemberID,
COALESCE(AGEQ1 / AGEQ1, 0)
+ COALESCE(AGEQ2 / AGEQ2, 0)
+ COALESCE(AGEQ3 / AGEQ3, 0)
+ COALESCE(AGEQ4 / AGEQ4, 0)
+ COALESCE(AGEQ5 / AGEQ5, 0)
+ COALESCE(AGEQ6 / AGEQ6, 0)
FROM dbo.table_name;
To get the number of people with each count of children, then:
;WITH y(y) AS
(
SELECT TOP (7) rn = ROW_NUMBER() OVER
(ORDER BY [object_id]) - 1 FROM sys.objects
),
x AS
(
SELECT
MemberID,
x = COALESCE(AGEQ1 / AGEQ1, 0)
+ COALESCE(AGEQ2 / AGEQ2, 0)
+ COALESCE(AGEQ3 / AGEQ3, 0)
+ COALESCE(AGEQ4 / AGEQ4, 0)
+ COALESCE(AGEQ5 / AGEQ5, 0)
+ COALESCE(AGEQ6 / AGEQ6, 0)
FROM dbo.table_name
)
SELECT
NumberOfChildren = y.y,
NumberOfPeopleWithThatMany = COUNT(x.x)
FROM y LEFT OUTER JOIN x ON y.y = x.x
GROUP BY y.y ORDER BY y.y;
I'd look at using UNPIVOT. That will make your wide column into rows. Since you don't care about what value was in a column, just the presence/absence of value, this will generate a row per not-null column.
The trick then becomes mashing that into the desired output format. It could probably have been done cleaner but I'm a fan of "showing my work" so that others can conform it to their needs.

from ( select id,
case when age1 is null then 0 else 1 end a,
case when age2 is null then 0 else 1 end b,

case when age5 is null then 0 else 1 end e,
case when age6 is null then 0 else 1 end f
from ages
) as t
See here in fiddle http://sqlfiddle.com/#!3/88020/1
To get the quantity of persons with childs
select childs, count(*) as ct
from (
select id, a+b+c+d+e+f childs
from

I am currently not able to sort the column to show up null values in the end
SELECT firstPart,secondPart FROM Exhibit_table d, ExhibitType a WHERE d.case_id ='13-05'
AND d.ExhibitTypeId = TypeId AND d.ComplianceNo = '0' and active = 1 order by CONVERT(INT, firstPart), secondPart
I have 2 columns firstpart and secondpart I need to sort it such a way that it shows in the following order
10
11
12 A
12 B
12 C
null null
null null
Any help is greatly appreciated
You can add a third sorting condition:
SELECT firstPart,secondPart
FROM Exhibit_table d, ExhibitType a
WHERE d.case_id ='13-05' AND d.ExhibitTypeId = TypeId AND d.ComplianceNo = '0' and active = 1
ORDER BY CASE WHEN firstPart IS NULL AND secondPart IS NULL THEN 0 ELSE 1 END,
CONVERT(INT, firstPart), secondPart
This will introduce a calculated field with value of 0 when both fields are NULL and value of 1 otherwise - and sort by that field. You can adjust that condition as needed.
It is really hard to find a good title for this.
Here is the question: I have a SELECT query GROUP BY a field which returns me up to three values (1,2,3). These values are representing the positions of '1' in a binary number.
In other words:
Query Output | Reult
0,1,2 | 7 (111)
1,2 | 6 (110)
3 | 1 (001)
- | 0 (000)
Ok, I know it is easy. But there are two constraints. First, I want a query not a function/store procedure. Second, the result should be a string (like '010') not the number.
I found the solution for integer value, but not the string (varchar)
SELECT COALESCE(sum(power(2, field)), 0) AS test FROM (
SELECT field FROM myTable GROUP BY field) a
I am using SQL server 2008, just in case.
I also have this solution, but this one cannot be extended to bigger number of outputs:
SELECT output =
CASE TEST
WHEN 0 THEN '000'
WHEN 1 THEN '001'
WHEN 2 THEN '010'
WHEN 3 THEN '011'
WHEN 4 THEN '100'
WHEN 5 THEN '101'
WHEN 6 THEN '110'
WHEN 7 THEN '111'
END
FROM(
select COALESCE(sum(power(2, 3 - field)), 0) as test from (
select field from myTable group by field) a) b
You can use binary and and string concatenation:
select (case when test&4 > 0 then '1' else '0' end) +
(case when test&2 > 0 then '1' else '0' end) +
(case when test&1 > 0 then '1' else '0' end)
from (select 6 as test) t;
If you are allergic to case statements, you could do this:
select CHAR(ascii(0) + (test&4)/4) +
CHAR(ascii(0) + (test&2)/2) +
CHAR(ascii(0) + (test&1)/1)
from (select 6 as test) t
I have three columns in the table MYTABLE (ID, NUM, NAMES). There is a column NAMES. I need to check on NAMES column to see if the first name is JACK or BRUCE and the corresponding NUM column = 0. If the match is found, return 1 else 0.
ID NUM NAMES
1 1 'TOM'
2 1 'MIKE'
3 0 'JACK'
4 1 'MICKY'
5 0 'BRUCE'
I've came up with the following query:
select *
case NAMES in ('JACK', 'BRUCE') and NUM=0 then 1 else 0 end as MYNAMES
from MYTABLE;
That does not work unfortunately.
This works (SQLFiddle demo):
SELECT id, num,
CASE WHEN names IN ('JACK', 'BRUCE') AND num=0
THEN 1 ELSE 0 END AS mynames
FROM mytable
select case
when exists
(
select *
from YourTable
where name in ('JACK', 'BRUCE')
and NUM = 0
)
then 1
else 0
end
from dual
Live example at SQL Fiddle.
select case when NAMES in ('JACK','BRUCE') AND NUM = 0
then 1
else 0
end
from your_table
