Using PostgreSQL I can have multiple rows of json objects.
select (select ROW_TO_JSON(_) from (select c.name, c.age) as _) as jsonresult from employee as c
This gives me this result:
{"age":65,"name":"NAME"}
{"age":21,"name":"SURNAME"}
But in SqlServer when I use the FOR JSON AUTO clause it gives me an array of json objects instead of multiple rows.
select c.name, c.age from customer c FOR JSON AUTO
[{"age":65,"name":"NAME"},{"age":21,"name":"SURNAME"}]
How to get the same result format in SqlServer ?
By constructing separate JSON in each individual row:
SELECT (SELECT [age], [name] FOR JSON PATH, WITHOUT_ARRAY_WRAPPER)
FROM customer
There is an alternative form that doesn't require you to know the table structure (but likely has worse performance because it may generate a large intermediate JSON):
SELECT [value] FROM OPENJSON(
(SELECT * FROM customer FOR JSON PATH)
)
no structure better performance
SELECT c.id, jdata.*
FROM customer c
cross apply
(SELECT * FROM customer jc where jc.id = c.id FOR JSON PATH , WITHOUT_ARRAY_WRAPPER) jdata (jdata)
Same as Barak Yellin but more lazy:
1-Create this proc
CREATE PROC PRC_SELECT_JSON(#TBL VARCHAR(100), #COLS VARCHAR(1000)='D.*') AS BEGIN
EXEC('
SELECT X.O FROM ' + #TBL + ' D
CROSS APPLY (
SELECT ' + #COLS + '
FOR JSON PATH, WITHOUT_ARRAY_WRAPPER
) X (O)
')
END
2-Can use either all columns or specific columns:
CREATE TABLE #TEST ( X INT, Y VARCHAR(10), Z DATE )
INSERT #TEST VALUES (123, 'TEST1', GETDATE())
INSERT #TEST VALUES (124, 'TEST2', GETDATE())
EXEC PRC_SELECT_JSON #TEST
EXEC PRC_SELECT_JSON #TEST, 'X, Y'
If you're using PHP add SET NOCOUNT ON; in the first row (why?).
Need your help. I am trying to convert below SQL query into RedShift, but getting error message "Invalid operation: This type of correlated subquery pattern is not supported yet"
SELECT
Comp_Key,
Comp_Reading_Key,
Row_Num,
Prev_Reading_Date,
( SELECT MAX(X) FROM (
SELECT CAST(dateadd(day, 1, Prev_Reading_Date) AS DATE) AS X
UNION ALL
SELECT dim_date.calendar_date
) a
) as start_dt
FROM stage5
JOIN dim_date ON calendar_date BETWEEN '2020-04-01' and '2020-04-15'
WHERE Comp_Key =50906055
The same query works fine in SQL Server. Could you please help me to run it in RedShift?

Kiru - you need to convert the correlated query into a join structure. Not knowing the data content of your tables and the exact expected out put I'm just guessing but here's a swag:
SELECT
Comp_Key,
Comp_Reading_Key,
Row_Num,
Prev_Reading_Date,
Max_X
FROM stage5
JOIN dim_date ON calendar_date BETWEEN '2020-04-01' and '2020-04-15'
JOIN ( SELECT MAX(X) as Max_X, MAX(calendar_date) as date FROM (
SELECT CAST(dateadd(day, 1, Prev_Reading_Date) AS DATE) AS X FROM stage5
cross join
SELECT dim_date.calendar_date from dim_date
) a
) as start_dt ON a.date = dim_date.calendar_date
WHERE Comp_Key =50906055
This is just a starting guess but might get you started.
However, you are likely better off rewriting this query to use window functions as they are the fastest way to perform these types of looping queries in Redshift.
Thanks Bill. It won't work in RedShift as it still has correalted sub-query.
However I have modified query in another method and it works fine.
I am closing ticket.
I am having a issue getting this Sub-query to run. I am using Toad Data Point -Oracle. I get syntax error. I have tried several different ways with no luck. I am knew to sub-query's

Your syntax is broken, you put subquery just at the end. Now it looks like:
select *
from dual as m
where a.dummy = m.dummy
(select dummy from dual)
It is in incorrect place, not joined, not aliased. What you should probably do is:
select *
from dual m
join (select dummy from dual) a on a.dummy = m.dummy
You also have some redundant, unnecessary brackets, but that's minor flaw. Full code (I cannot test it without data access):
select *
from FINC.VNDR_ITEM_M M
join (SELECT A.CLIENT_ID, A.SRC_SYS_ID, A.CO_CD, A.ACCT_NBR, A.CLR_DT, A.ASGN_NBR,

and B.SRC_SYS_ID ='15399' and B.FISCAL_YR ='2018')

You need to add an alias to the SubSelect (or Derived Table in Standard SQL):
select *
from
( select .......
) AS dt
join ....
I have been trying to pull up the data from Contract, ContractDetail, ContractItem and InventoryItem in Generic Inquiry. So, after adding up all 4 tables I created relationship as below.
The relationship between Contract and ContractDetail is fine. And now since ContractDetail uses ContractItemID, I have set the relationship as below. But it throws me error like this.
And, upon looking into the stack trace, I find the generated query looks this:
DECLARE #P0 SmallDateTime(4) SET #P0='9/27/2018 12:00:00 AM' DECLARE #P1 nvarchar(MAX) SET #P1='0' SELECT COUNT(*)
FROM (
[Contract] InnerQuery_Contract
INNER JOIN (
[ContractDetail] InnerQuery_ContractDetail_ContractDetail
INNER JOIN [Contract] InnerQuery_ContractDetail_Contract ON [InnerQuery_ContractDetail_Contract].CompanyID IN (1, 3) AND 32 = SUBSTRING([InnerQuery_ContractDetail_Contract].CompanyMask, 1, 1) & 32 AND [InnerQuery_ContractDetail_Contract].[DeletedDatabaseRecord] = 0 AND [InnerQuery_ContractDetail_ContractDetail].[ContractID] = [InnerQuery_ContractDetail_Contract].[ContractID] AND [InnerQuery_ContractDetail_ContractDetail].[RevID] = [InnerQuery_ContractDetail_Contract].[RevID]
LEFT JOIN
[ContractDetail] InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt
ON [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].[ContractID] = [InnerQuery_ContractDetail_ContractDetail].[ContractID] AND [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].[LineNbr] = [InnerQuery_ContractDetail_ContractDetail].[LineNbr] AND [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].[RevID] = [InnerQuery_ContractDetail_Contract].[LastActiveRevID] AND [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].CompanyID = 3
) ON [InnerQuery_Contract].[ContractID] = [InnerQuery_ContractDetail_ContractDetail].[ContractID] AND [InnerQuery_ContractItem].[ContractItemID] = [InnerQuery_ContractDetail_ContractDetail].[ContractItemID] AND [InnerQuery_ContractDetail_ContractDetail].CompanyID = 3
INNER JOIN [ContractItem] InnerQuery_ContractItem ON [InnerQuery_ContractItem].CompanyID = 3 AND [InventoryItem].[inventoryID] = [InnerQuery_ContractItem].[RecurringItemID]
)
WHERE [InnerQuery_Contract].CompanyID IN (1, 3) AND 32 = SUBSTRING([InnerQuery_Contract].CompanyMask, 1, 1) & 32 AND [InnerQuery_Contract].[DeletedDatabaseRecord] = 0 AND [InnerQuery_Contract].[UsrLockDate] < #P0 AND (CASE WHEN ([InnerQuery_Contract].[BaseType] = 'T' OR [InnerQuery_Contract].[BaseType] = 'R') THEN CONVERT (BIT, 1) ELSE CONVERT (BIT, 0) END) = #P1 OPTION(OPTIMIZE FOR UNKNOWN)
So, there is problem with Alias name for table in the query. So, how do I fix this issue?
Thank you.
Joins in Acumatica works exactly like in SQL. First build the query in SQL and get the result as to what you need and then try to construct the same in Generic Inquiry.
Apart from than, I do not see any relations between Contracts and Inventory. Please explain what you are trying to get.
Here is the way you should join your tables in Generic Inquiry
I use standard sql and want to extract third substring from the end.
Example Input: "Search-site-variable-brand-0-city-none-18053517"
Output: "city"
I just wanted to point out that if you plan to apply this transformation to multiple columns, it may be useful to pull the logic into a UDF. Here's an example of how to do that:
CREATE TEMP FUNCTION SecondSubstringFromEnd(s STRING) AS ((
SELECT arr[SAFE_OFFSET(ARRAY_LENGTH(arr) - 3)]
FROM (
SELECT SPLIT(s, '-') AS arr
)
));
WITH Input AS (
SELECT 'Search-site-variable-brand-0-city-none-18053517' AS str UNION ALL
SELECT 'a-b' UNION ALL
SELECT 'w-x-yyy-z'
)
SELECT
str,
SecondSubstringFromEnd(str) AS second_substring_from_end
FROM Input;
This might do the trick:
WITH data AS(
select "Search-site-variable-brand-0-city-none-18053517" as Input
)
SELECT
CASE WHEN ARRAY_LENGTH(SPLIT(Input, '-')) > 3 THEN SPLIT(Input, '-')[OFFSET(ARRAY_LENGTH(SPLIT(Input, '-')) - 3)] END word
FROM data
It returns NULL in case the string has no split, such as empty strings.
Few more variations for BigQuery Standard SQL:
#standardSQL
WITH YourTable AS(
SELECT 'Search-site-variable-brand-0-city-none-18053517' AS Input UNION ALL
SELECT 'Second-substring-from-the-end-in-Google-BigQuery' UNION ALL
SELECT 'bigQuery-assign-a-value-to-table-1-based-on-table-2' UNION ALL
SELECT 'Error-Message-Too-many-sources-provided-15285-Limit-is-10000' UNION ALL
SELECT 'Google-Bigquery-data-import-from-Google-Analytics-360' UNION ALL
SELECT 'Bigquery-Partitioning-data-past-2000-limit'
)
SELECT
Input,
REVERSE(SPLIT(REVERSE(Input), '-')[SAFE_ORDINAL(3)]) AS Output_1,
ARRAY_REVERSE(SPLIT(Input, '-'))[SAFE_ORDINAL(3)] AS Output_2
FROM YourTable
The "ARRAY_REVERSE" function works wonders in this scenario.
with input AS
(
SELECT "Search-site-variable-brand-0-city-none-18053517" AS to_reverse_string
)
SELECT ARRAY_REVERSE(SPLIT(to_reverse_string, "-"))[SAFE_OFFSET(2)]
FROM input
