FOR XML PATH in Postgres - postgresql

Hi everyone I'm trying convert this code so it works in postgres. I figured I will use to_char(dateinquar:: date, 'mm/dd/yyyy') instead of convert(varchar,dateinquar,101). But I'm not sure what can be used instead of FOR XML PATH? I don't need to generate any XML document. How would I get multiple dates in a single row separated by comma for the case below?
Case d.Closing WHEN 0 THEN NULL WHEN 1 THEN (
substring((SELECT convert(varchar,dateinquar,101) + ', ' FROM PDT_tblAReasons sub
WHERE sub.IDnumber = d.IDnumber and dateoutquar IS NULL
GROUP BY IDnumber,dateinquar FOR XML PATH('')),0,len((
SELECT convert(varchar,dateinquar,101) + ', ' FROM PDT_tblAReasons sub
WHERE sub.IDnumber = d.IDnumber and dateoutquar IS NULL
GROUP BY IDnumber,dateinquar FOR XML PATH('')))-0)) end As [Closing Date]
Thank you

Trying to extract text using CHARINDEX ()- 1 but getting an error

I have a column with Names, and I am trying to split the column into First and Last Name using Text functions such as LEFT/SUBSTRING/CHARINDEX.
Data in the column:
Name
Yang, Jon
Huang, Eugene
Torres, Ruben
Zhu, Christy
Johnson, Elizabeth
Everything works fine as long as I use this code:
SELECT
[Name]
--,LEFT([Name], CHARINDEX(' ', [Name])) AS FirstName
,SUBSTRING([Name], 1, CHARINDEX(' ', [Name] )) AS FirstName
FROM
DataModeling.Customer
But the problem arises when I try to subtract 1 from CHARINDEX to exclude the Comma from the result and it throws this error:
I have done this operation many times in Excel so trying to replicate it with TSQL. Any suggestion on what I am doing wrong is helpful.
You get that error when CHARINDEX(' ', [Name] ) return 0. So minus 1 will make it negative and it is invalid value for substring()
You can use CASE expression to check the return value from CHARINDEX() and return the correct value to substring()
Or, you can "cheat" by using
CHARINDEX( ' ', [Name] + ' ' )
So CHARINDEX() will always return a value that is more than 0

# in Caché between columns

I have a SQL query and I would like to insert a hashtag between one column and another to be able to reference in Excel, using an import option in fields delimited by #. Anyone have an idea how to do it? A query is as follows:
SELECT FC.folha, folha->folhames,folha->folhaano, folha->folhaseq, folha->folhadesc, folha->TipoCod as Tipo_Folha,
folha->FolhaFechFormatado as Folha_Fechada, folha->DataPagamentoFormatada as Data_Pgto,
Servidor->matricula, Servidor->nome, FC.rubrica,
FC.Rubrica->Codigo, FC.Rubrica->Descricao, FC.fator, FC.TipoRubricaFormatado as TipoRubrica,
FC.ValorFormatado,FC.ParcelaAtual, FC.ParcelaTotal
FROM RHFolCalculo FC WHERE folha -> FolhaFech = 1
AND folha->folhaano = 2018
and folha->folhames = 06
and folha->TipoCod->codigo in (1,2,3,4,6,9)
You are generating delimited output from the query, so the first row should be a header row, with all following rows the data rows. You will really only have one column due to concat. So remove the alias from the columns, output the first row like so (using the alias here) . . .
SELECT 'folha#folhames#folhaano#folhaseq#folhadesc#Tipo_Folha#
Folha_Fechada#Data_Pgto#
matricula#nome#rubrica#
Codigo#Descricao#fator#TipoRubrica#
ValorFormatado#ParcelaAtual#ParcelaTotal'
UNION
SELECT FC.folha || '#' || folha->folhames || '#' || folha->folhaano . . .
The UNION will give the remaining rows. Note some conversion may be necessary on the columns data if not all strings.

How to fetch a part of string upto a chracter?

I want to fetch the names of employees from a table upto the character ':' but couldn't as substr and ltrim is not working as expected. Below given are given some examples:
ABINERI:REBECCA C
CARRINGTON:JAMES M
But I want them in the way given below:
REBECCA C ABINERI
JAMES M CARRINGTON
I just used the query below in Toad for Oracle:
<pre>
<b>select name from employees</b>
</pre>
Please try below query:
select SUBSTR(name,(INSTR(name,':')+1)) || ' ' || SUBSTR(name,1,(INSTR(name,':'))-1) from employees;
hope above query will resolve your issue.

How to translate the PostgreSQL array_agg function to SQLite?

This query works in PostgreSQL:
Select ot.MCode,array_to_string(array_agg(tk1.TName || ',' || ot.TTime), ' - ') as oujyu_name_list
From TR_A ot
inner join MS_B tk1 on ot.Code = tk1.Code
Where ot.Code in (Select Code From TR_C )
Group byot.MCode
but it does not work in SQLite, because SQLite does not have the array_agg() function. How can this query be converted to SQLite?
For this query, you can use group_concat, which directly returns a string:
SELECT ..., group_concat(tk1.TName || ',' || ot.TTime, ' - ')
FROM ...
SQLite now has the JSON1 extension (which ships in the default distribution) that can group and create arrays of JSON objects. For example,
select
ot.MCode,
json_group_array(json_object('tname', tk1.TName, 'ttime', ot.TTime)) as oujyu_name_list
from TR_A as ot
inner join MS_B as tk1
on (ot.Code = tk1.Code)
where ot.Code in (select code from TR_C)
group by ot.MCode;
The second column will be formatted as a JSON array e.g. [{"tname":...,"ttime":...},...].

Dynamic pivot - how to obtain column titles parametrically?

I wish to write a Query for SAP B1 (t-sql) that will list all Income and Expenses Items by total and month by month.
I have successfully written a Query using PIVOT, but I do not want the column headings to be hardcoded like: Jan-11, Feb-11, Mar-11 ... Dec-11.
Rather I want the column headings to be parametrically generated, so that if I input:
--------------------------------------
Query - Selection Criteria
--------------------------------------
Posting Date greater or equal 01.09.10
Posting Date smaller or equal 31.08.11
[OK] [Cancel]
the Query will generate the following columns:
Sep-10, Oct-10, Nov-10, ..... Aug-11
I guess DYNAMIC PIVOT can do the trick.
So, I modified one SQL obtained from another forum to suit my purpose, but it does not work. The error message I get is Incorrect Syntax near 20100901.
Could anybody help me locate my error?
Note: In SAP B1, '[%1]' is an input variable
Here's my query:
/*Section 1*/
DECLARE #listCol VARCHAR(2000)
DECLARE #query VARCHAR(4000)
-------------------------------------
/*Section 2*/
SELECT #listCol =
STUFF(
( SELECT DISTINCT '],[' + CONVERT(VARCHAR, MONTH(T0.RefDate), 102)
FROM JDT1
FOR XML PATH(''))
, 1, 2, '') + ']'
------------------------------------
/*Section 3*/
SET #query = '
SELECT * FROM
(
SELECT
T0.Account,
T1.GroupMask,
T1.AcctName,
MONTH(T0.RefDate) as [Month],
(T0.Debit - T0.Credit) as [Amount]
FROM dbo.JDT1 T0
JOIN dbo.OACT T1 ON T0.Account = T1.AcctCode
WHERE
T1.GroupMask IN (4,5,6,7) AND
T0.[Refdate] >= '[%1]' AND
T0.[Refdate] <= '[%2]'
) S
PIVOT
(
Sum(Amount)
FOR [Month] IN ('+#listCol+')
) AS pvt
'
--------------------------------------------
/*Section 4*/
EXECUTE (#query)
I don't know SAP, but a couple of things spring to mind:
It looks like you want #listCol to contain a collection of numbers within square brackets, for example [07],[08],[09].... However, your code appears not to put a [ at the start of this string.
Try replacing the lines
T0.[Refdate] >= '[%1]' AND
T0.[Refdate] <= '[%2]'
with
T0.[Refdate] >= ''[%1]'' AND
T0.[Refdate] <= ''[%2]''
(I also added a space before the AND in the first of these two lines while I was editing your question.)
