I am trying to load data to ADLS gen2 from Azure SQL DB in json format.
Below is the query I am using to load it in JSON format
select k2.[mandt],k2.[kunnr],
'knb1' = (select [bukrs] as 'bukrs' , [pernr]
from [ods_cdc_sdr].[knb1] k1
where k2.mandt=k1.mandt AND K1.kunnr=K2.kunnr
FOR JSON PATH),
'knvp' =(select knvp.vkorg, vtweg from [ods_cdc_sdr].[knvp] knvp where k2.mandt=knvp.mandt AND knvp.kunnr=K2.kunnr FOR JSON PATH)
from [ods_cdc_sdr].[kna1] k2
group by k2.[mandt],k2.[kunnr]
FOR JSON PATH
For one or two records data looks fine but when I am trying to load 1000 and above records, json seems to be splitting also not in a proper format (below is the example)

Please help me how can I get entire message in a proper format```
If you just want to save query result in json format to ADLS. You'd better remove FOR JSON PATH. We can use Azure Data Factory to generate nested JSON.
I created a simple test with two tables. Table Entities and table EntitiesEmails are related through the Id and EntitiyId fields. Usually we can use following sql to return a nested json type array. But ADF will automatically add escape characters '\' to escape double quotes.
SELECT
ent.Id AS 'Id',
ent.Name AS 'Name',
ent.Age AS 'Age',
EMails = (
SELECT
Emails.EntitiyId AS 'Id',
Emails.Email AS 'Email'
FROM EntitiesEmails Emails WHERE Emails.EntitiyId = ent.Id
FOR JSON PATH
)
FROM Entities ent
FOR JSON PATH
I researched out the use of data flow to generate a nested json array. As follows show:
Set source1 to the SQL table Entities .
Set source2 to the SQL table EntitiesEmails .
At Aggregate1 activity, set Group By Aggregate1
Type in expression collect(Email) at Aggregates. It will collect all email addresses into an array.
Data preview is as follows:
Then we can join these two streams at Join1 activity.
Then we can filter out extra columns at Select1 activity.
Then we can sink the result to our json file in ADLS.
Debug output is as follows:
I'm working with a access database and vb6. My table has a field named "InvoiceDate" which is a text field. I'm not allowed to make database modifications. So I guess my only option is to change the text field into a date/time field in my query. I found several methods to do so. They are as follows.
Format(InvoiceDate, "yyyy/mm/dd")
(DateSerial(Left(InvoiceDate,4),Mid(InvoiceDate,5,2),Right(InvoiceDate,2))
Between #2015/01/01# And #2016/01/01#))
DateValue(InvoiceDate, "yyyy/mm/dd")
CDate(InvoiceDate, "yyyy/mm/dd")
But those 4 methods didn't work. I can't figure out this.
The query I'm using as follows
SELECT Invoice.InvoiceDate, InvoicedProduct.InvoiceType, Invoice.InvoiceStatus,
Invoice.RetailerID, Invoice.DailySalesID, Invoice.RepID,
InvoicedProduct.Quantity, InvoicedProduct.UnitRate,
InvoicedProduct.TotalItemValue
FROM Invoice
INNER JOIN InvoicedProduct
ON (Invoice.DailySalesID = InvoicedProduct.DailySalesID)
AND (Invoice.RepID = InvoicedProduct.RepID)
AND (Invoice.InvoiceID = InvoicedProduct.InvoiceID)
WHERE (((InvoicedProduct.ProductID)='9010001174130.4')
AND (DateValue(Invoice.InvoiceDate) Between #2015/01/01# And #2016/01/01#))
GROUP BY Invoice.InvoiceDate, InvoicedProduct.InvoiceType, Invoice.InvoiceStatus,
Invoice.RetailerID, Invoice.DailySalesID, Invoice.RepID,
InvoicedProduct.Quantity, InvoicedProduct.UnitRate,
InvoicedProduct.TotalItemValue
HAVING (((InvoicedProduct.InvoiceType)='Invoice' OR (InvoicedProduct.InvoiceType)='Sound')
AND ((Invoice.InvoiceStatus)='VALID'))
ORDER BY Invoice.InvoiceDate;
This gives me the error "Data Type mismatch in criteria expression"
Following two types are include in my InvoiceDate Field
2016/01/04 10:00: AM and 2016/01/20 08:25 PM
The only difference is the colon after the time
Please help.
Thank you.
Your criteria:
DateValue(Invoice.InvoiceDate) Between #2015/01/01# And #2016/01/01#
is correct, so the error message indicates, that one or more of your text dates in InvoiceDate don't represent a valid date, like 2015-06-31 or Null.
Run a query to check this:
Select *, IsDate(InvoiceDate) As ValidDate From Invoice
and see if any of the values of ValidDate are False.
To ignore the extra colon:
DateValue(Replace(Invoice.InvoiceDate, ": ", " ")) Between #2015/01/01# And #2016/01/01#
