If else Condition in PostgreSql - postgresql

I have Query which need to be modified like if I pass zone=All then it should display all records else other condition. This query I have to use in SSRS Reports, it works in this condition.
select distinct zone, wardno,deptname,
cybertec_view_requests.statusname,
categoryname,opendate,probdesc
from cybertec_view_requests
left join cybertec_view_requests_comments on
cybertec_view_requests_comments.reqid = cybertec_view_requests.id_
where zone= ? and deptname=? and
opendate between ? and ? and categoryname=?
group by zone,wardno,deptname, cybertec_view_requests.statusname,
categoryname,opendate,probdesc
order by zone,wardno,deptname


try this
Hear #zone is your variable to pass in the Query
SELECT DISTINCT zone, wardno,deptname, cybertec_view_requests.statusname, categoryname,opendate,probdesc
FROM cybertec_view_requests
LEFT JOIN cybertec_view_requests_comments ON cybertec_view_requests_comments.reqid = cybertec_view_requests.id_
WHERE zone= CASE WHEN #zone = 'ALL' THEN zone ELSE #zone END and deptname=? and
opendate between ? and ? and categoryname=?
GROUP BY zone,wardno,deptname, cybertec_view_requests.statusname,
categoryname,opendate,probdesc
ORDER BY zone,wardno,deptname

find the first date after a given date in SQL

I have two tables related to vital signs like below:
enter image description here
and have the second table

I want to show the table below:

My problem is when I used with statement in SQL to join the tables, the date sometimes didn't show the first record after the date of admission, but it showed the second or third one like this:

Query returning different number of rows, results in crosstab error

When run seperately, I get 295 results which is correct. However putting it together in the whole query gets the error.

The manual:
The remaining output columns must have the type of the last column of the source_sql query's result, and there must be exactly as many of them as there are rows in the category_sql query's result.
crosstab(text, text) with a dynamic (!) SELECT query as 2nd parameter is very error prone, since the output column list is static. You should also generate the output column list dynamically. Example:
Dynamic alternative to pivot with CASE and GROUP BY
That aside, the different number of rows returned from the same query, may very well be due to a different timezone setting in the two different sessions.
You have the expression TO_CHAR(b.invoicedate, 'YYYY-MM-DD') in your predicates. If b.invoicedate is type timestamptz the result depends on the timezone setting. Consider:
SET timezone = '+10';
SELECT TO_CHAR(timestamptz '2018-04-07 23:30+0', 'YYYY-MM-DD');
to_char
----------
2018-04-08
SET timezone = '-10';
SELECT TO_CHAR(timestamptz '2018-04-07 23:30+0', 'YYYY-MM-DD');
to_char
----------
2018-04-07
Solution
To remove the dependency on the timezone setting, use absolute values.
to_char() is expensive complication in this place to begin with. Drop that and adjust the predicate.
Provide timestamptz values to match your column. This also allows indexes to be used (if applicable).

I suggest this as 2nd parameter:
$$
SELECT l.locationcode
FROM locationinfo l
JOIN invoiceinfo b ON b.location = l.locationid
WHERE b.status <> 2 AND l.locationtype = 1 AND l.status = 1
AND b.invoicedate >= timestamptz '2018-03-01 Europe/Vienna'
AND b.invoicedate < timestamptz '2018-03-04 Europe/Vienna'
GROUP BY 1
ORDER BY 1
$$
Replace Europe/Vienna in my example with the time zone name defining your dates.
Note 2018-03-04 to include all of 2018-03-03 like you intended.

GROUP BY tson.max_tarih
Group by error is : To use the aggregate function, you must add the column "b.tarih" to the GROUP BY list.
When I add it I get the same error for another column.I'm waiting for your help.

You are using a feature of MySQL that is not standard SQL and you can also deactivate.
You are grouping by tson.max_tarih in your query. That means that for all rows that share the same value in that field, you will get only one row as a result of that group.
If you have several different values in the rest of the fields (enlem, boylam, etc...) which one are you trying to get in as the result of the query? That's the question that PostgreSQL is asking you.
MySQL is just returning any value for those fields among the rows in the group. PostgreSQL requires you to actually specify it.
Two typical solutions would be grouping by the rest of the fields (b.tarih, b.enlem) or specifying the value those fields to something like MAX(b.tarih), etc.

How to match starting date to the closest ending date in order to get the time difference

SELECT
OUT.EMP_ID,
OUT.DT_TM "DateTimeOut",
IN.DT_TM "DateTimeIn",
cast(timestampdiff( 4, char(timestamp(IN.DT_TM) - timestamp(OUT.DT_TM))) as decimal(30,1))/60 "Duration Out"
FROM (
select
e1.EMP_ID,
e1.DT_TM
from
hr.timeout e1
WHERE
month(e1.DT_TM)=09
and year(e1.DT_TM)=2016
AND e1.CD='OUT'
) OUT
LEFT JOIN (
select
e2.EMP_ID,
e2.DT_TM
from
hr.timeout e2
WHERE
month(e2.dt_tm)=09
and year(e2.dt_tm)=2016
AND e2.CD='IN'
) IN
on out.EMP_ID=in.EMP_ID
Trying to get the closest DateTimeIn match with the DateTimeOut.
Currently it repeats the same DateTimeOut and DateTimeIn multiple times.

I think its normal because your table dont have constraint unique on emp_id, dt_tm and cd. But if you want unique result try this :
With Period as (
select e1.EMP_ID, e1.DT_TM from hr.timeout e1
WHERE month(e1.DT_TM)=09 and year(e1.DT_TM)=2016
)
Select distinct OUT.EMP_ID, IN.DT_TM as DateTimeIn, OUT.DT_TM as DateTimeOut,
TIMESTAMPDIFF(2 , CAST(timestamp(IN.DT_TM) - timestamp(ifnull(OUT.DT_TM, current date)) AS CHAR(22)) ) as DurationSecond
from Period in left outer join Period out
on out.EMP_ID=in.EMP_ID and out.CD='OUT' and in.CD='IN'
order by 1, 2, 3
Like you can see, i use timestampdiff with '2' like first parameter for second (you divided by 60), i use ifnull because you do a left outer join (out.DT_TM can be null) and i do a distinct for unique result
