I am trying to pass the each line of json file to the SQL Select statement.How I can pass the values using python in iterative way
Json File contains following lines :
{"row_id":"1","a":"600","b":"hello","date":"2017-07-01","enabled":"TRUE","id":"234"}
{"row_id":"2","a":"650","b":"world","date":"2018-08-02","enabled":"FALSE","id":"456"}
{"row_id":"3","a":"700","b":"world","date":"2019-02-10","enabled":"FALSE","id":"789"}
I am trying to pass each line values to the sql statement.
Eg :
when row_id = 1 then it should pass the values of the respective line
Select * from xyz where a='600' and b='hello' and date ='2017-07-01';
when row_id =2 then then it should pass the values of the respective line
Select * from xyz where a='650' and b='world' and date ='2018-08-02';
when row_id =2 then then it should pass the values of the respective line
Select * from xyz where a='700' and b='world' and date ='2019-02-10';
Thank you
Assuming you are passing one JSON object at a time
Example
Declare #JSON varchar(max) ='{"row_id":"1","a":"600","b":"hello","date":"2017-07-01","enabled":"TRUE","id":"234"}'
SELECT *
From xyz
Where a = JSON_VALUE(#JSON, '$.a')
and b = JSON_VALUE(#JSON, '$.b')
and date = JSON_VALUE(#JSON, '$.date')

In a stored procedure I have a for json node (boxes):
select
(
select
os.Name,
os.Address,
ss.carrierCode,
(
select
ob.envelopeCode,
ob.boxNumber,
ob.weight,
ob.width,
ob.length,
ob.height
from OrdersBoxes ob
...
where os.OID=ob.OID
...
for json path
) boxes,
....
for json path
) orderDetails
In this way I correctly get:
"boxes":[{
"envelopeCode":"E70345D2AB90A879D4F53506FB465086",
"boxNumber":1,
"weight":3000,
"width":300,
"length":300,
"height":100
}]
Now I need to get details from 2 tables, therefore I will use union command, wrap the 2 select in another select the query to avoid following error:
The FOR XML and FOR JSON clauses are invalid in views, inline functions, derived tables, and subqueries when they contain a set operator. To work around, wrap the SELECT containing a set operator using derived table or common table expression or view and apply FOR XML or FOR JSON on top of it.
And add JSON_QUERY to avoid to get escaped nested node:
select
(
select
*
from
(
select
os.Name,
os.Address,
ss.carrierCode,
JSON_QUERY((
select
ob.envelopeCode,
ob.boxNumber,
ob.weight,
ob.width,
ob.length,
ob.height
from OrdersBoxes ob
...
where os.OID=ob.OID
...
for json path
)) boxes,
....
from table1
where....
union
select
os.Name,
os.Address,
ss.carrierCode,
JSON_QUERY((
select
ob.envelopeCode,
ob.boxNumber,
ob.weight,
ob.width,
ob.length,
ob.height
from OrdersBoxes ob
...
where os.OID=ob.OID
...
for json path
)) boxes,
....
from table2
where....
) jj
for json path
) orderDetails
That works, but boxes node is returned escaped:
"boxes":"[{\"envelopeCode\":\"E70345D2AB90A879D4F53506FB465086\",\"boxNumber\":1,\"weight\":3000,\"width\":300,\"length\":300,\"height\":100}]"
I tried also this Solution but it works well only if returning data from 1 table:
since it returns objects {} to get an array need to change first line from
select STRING_AGG (order_details,',') ods from (
to
select concat('[',STRING_AGG (order_details,','),']') ods from (
and it seems me not very "elegant" although it works.
Can someone suggest a better way to get all data correctly formatted (thus unescaped boxes node)?
The documentation about JSON_QUERY() explains: ... JSON_QUERY returns a valid JSON fragment. As a result, FOR JSON doesn't escape special characters in the JSON_QUERY return value. If you're returning results with FOR JSON, and you're including data that's already in JSON format (in a column or as the result of an expression), wrap the JSON data with JSON_QUERY without the path parameter.. So, if I understand the schema correctly, you need to use JSON_QUERY() differently:
Tables:
SELECT *
INTO table1
FROM (VALUES
(1, 'Name1', 'Address1')
) v (oid, name, address)
SELECT *
INTO table2
FROM (VALUES
(2, 'Name2', 'Address2')
) v (oid, name, address)
SELECT *
INTO OrdersBoxes
FROM (VALUES
(1, 'E70345D2AB90A879D4F53506FB465086', 1, 3000, 300, 300, 100),
(2, 'e70345D2AB90A879D4F53506FB465086', 2, 3000, 300, 300, 100)
) v (oid, envelopeCode, boxNumber, weight, width, length, height)
Statement:
select Name, Address, JSON_QUERY(boxes) AS Boxes
from (
select
os.Name,
os.Address,
(
select ob.envelopeCode, ob.boxNumber, ob.weight, ob.width, ob.length, ob.height
from OrdersBoxes ob
where os.OID = ob.OID
for json path
) boxes
from table1 os
union all
select
os.Name,
os.Address,
(
select ob.envelopeCode, ob.boxNumber, ob.weight, ob.width, ob.length, ob.height
from OrdersBoxes ob
where os.OID = ob.OID
for json path
) boxes
from table2 os
) j
for json path
As an additional option, you may try to use FOR JSON AUTO (the format of the JSON output is automatically determined based on the order of columns in the SELECT list and their source tables):
SELECT
cte.Name, cte.Address,
boxes.envelopeCode, boxes.boxNumber, boxes.weight, boxes.width, boxes.length, boxes.height
FROM (
SELECT oid, name, address FROM table1
UNION ALL
SELECT oid, name, address FROM table2
) cte
JOIN OrdersBoxes boxes ON cte.oid = boxes.oid
FOR JSON AUTO
Result:
[
{
"Name":"Name1",
"Address":"Address1",
"boxes":[{"envelopeCode":"E70345D2AB90A879D4F53506FB465086","boxNumber":1,"weight":3000,"width":300,"length":300,"height":100}]
},
{
"Name":"Name2",
"Address":"Address2",
"boxes":[{"envelopeCode":"e70345D2AB90A879D4F53506FB465086","boxNumber":2,"weight":3000,"width":300,"length":300,"height":100}]
}
]
I have following query in ORACLE:
SELECT *
FROM "Supplier" s
OUTER APPLY(
SELECT JSON_ARRAYAGG(JSON_OBJECT(p."Id", p."Description", p."Price")) as "Products"
FROM "Products" p
WHERE p."SupplierId" = s."Id"
) sp
In OUTER APPLY subquery I am creating json from columns I need and then aggregating those objects into json array. I need those two functions because sometimes I use only one of them. The same operation I would like to do in SqlServer. This is solution I managed so far:
SELECT *
FROM "Supplier" as s
OUTER APPLY(
SELECT p."Id", p."Description", p."Price"
FROM "Products" as p
WHERE p."SupplierId" = s."Id"
FOR JSON PATH
) as sp("Products")
The problem is that SqlServer executing those two functions at once (this is purpose for FOR JSON PATH statement). So here are my questions:
1) Is there possible to create json object without wrapping it into array (oracle-like syntax)?
2) Is there possible to aggregate json objects into an array?
UPDATE
I am using SqlServer version 2019 15.0.2000.5
Expected result (single record of products in json format)
"Products":{
"Id":"FEB0646B709B45B5A306E10599716F28",
"Description":"Database Manager",
"Price":149.99
}
If I understand the question correctly, the following statements are possible soltion (of course, they are based on the example data and statements in the question):
How to create a single JSON object:
If you want to generate one single JSON object, you need to use FOR JSON PATh for each row in the OUTER APPLY statement with the appropriate path expression. JSON_QUERY() is needed, because it returns a valid JSON and FOR JSON doesn't escape special characters.
Tables:
CREATE TABLE Supplier (
Id int,
Description varchar(50),
DateStart date
)
CREATE TABLE Products (
Id varchar(5),
SupplierId int,
Description varchar(100),
Price numeric(10, 2)
)
INSERT INTO Supplier (Id, Description, DateStart)
VALUES (1, 'Oracle', '19900505')
INSERT INTO Products (Id, SupplierId, Description, Price)
VALUES ('11111', 1, 'Database Manager', 149.99)
INSERT INTO Products (Id, SupplierId, Description, Price)
VALUES ('22222', 1, 'Chassi', 249.99)
Statement:
SELECT *
FROM "Supplier" s
OUTER APPLY(
SELECT Products = JSON_QUERY((
SELECT
p."Id" AS 'Product.Id',
p."Description" AS 'Product.Description',
p."Price" AS 'Product.Price'
FOR JSON PATH, WITHOUT_ARRAY_WRAPPER
))
FROM "Products" as p
WHERE p."SupplierId" = s."Id"
) sp ("Products")
Result:
Id Description DateStart Products
1 Oracle 1990-05-05 {"Product":{"Id":"11111","Description":"Database Manager","Price":149.99}}
1 Oracle 1990-05-05 {"Product":{"Id":"22222","Description":"Chassi","Price":249.99}}
How to aggregate JSON objects into an array:
By default FOR JSON creates a JSON array with one JSON object for each row. You only need to set a root key:
Statement:
SELECT *
FROM "Supplier" s
OUTER APPLY(
SELECT p."Id", p."Description", p."Price"
FROM "Products" p
WHERE p."SupplierId" = s."Id"
FOR JSON PATH
) sp("Products")
Result:
Id Description DateStart Products
1 Oracle 1990-05-05 [{"Id":"11111","Description":"Database Manager","Price":149.99},{"Id":"22222","Description":"Chassi","Price":249.99}]

I received a valid JSON string from client side, it contains an array of integer values:

How to select the market IDs correctly?
If I use a query like this: select * from openjson(#JSON) j, it returns
The type of Markets is 4, which means an object,
but the query below returns null value:
select j.Markets from openjson(#JSON) with(Markets nvarchar(max)) j
My goal is to update Market table based on these IDs, eg:
update Market set Active = 1 where MarketID in (3, 151)
Is there a way to do this?
Any built-in function compatible with SQL server 2016 can be used.
Note:
Thanks to #johnlbevan
SELECT VALUE FROM OPENJSON(#JSON, '$.Markets') works perfectly for this problem.
Just for the completeness, here is how I created the JSON integer array ("Markets": [3, 151]) from SQL server.
Since there is no array_agg function out of the box in 2016, I did this:
SELECT (
JSON_QUERY('[' + STUFF(( SELECT ',' + CAST(MarketID AS VARCHAR)
FROM Market
FOR XML PATH('')),1,1,'') + ']' ) AS Markets)
To expand the Markets array alongside other columns you can do this:
SELECT Comments, Market
FROM OPENJSON('{"Comments": "test", "Markets": [3, 151]}')
WITH (Comments nvarchar(32), Markets NVARCHAR(MAX) AS JSON) AS a
CROSS APPLY OPENJSON (a.Markets) WITH (Market INT '$') AS b
Convert the string to json
Map the first field returned to the Comments column with type nvarchar(32)
Map the second field to Markets column with type nvarchar(max), then use as json to say that the contents is json (see https://learn.microsoft.com/en-us/sql/t-sql/functions/openjson-transact-sql#arguments for a more detailed description - search the page for as json; the key paragraph starts at the 4th occurrence)
Use a cross apply to apply the OPENJSON function to the Markets column so we can fetch values from that property.
Finally use the WITH statement to map the name Market to the returned value, and assign it a data type of INT.
However, to just get the list of values needed to do the update, you can do this:
UPDATE Market
SET Active = 1
WHERE MarketID IN
(
SELECT value
FROM OPENJSON('{"Comments": "test", "Markets": [3, 151]}','$.Markets')
);
Again OPENJSON lets us query the string as JSON
However this time we specify a path to point at the Markets value directly (see https://learn.microsoft.com/en-us/sql/t-sql/functions/openjson-transact-sql)
We now return the values returned and filter our UPDATE on those, as we would were we dealing with any other subquery.
In my table, the value column contains json data. I am using parsejson to parse these values. I am using older version of SQL Server. So I am using parsejson:
id fieldid value
--------------------------------------------------------------------
1 70297 {"value":"Billable ","text":"Billable"}
2 70297 [{"value":"billable","text":"Billable"}]
3 70297 [{"value":"billable","text":"Billable"},
{"value":"nonbillable","text":"NonBillable"}]
4 70297 [{"value":" nonbillable","text":" NonBillable"}]
I need this output:
count stringvalue
--------------------
3 Billable
2 nonbillable
I am using this query to parse above json values from the table:
DECLARE #Names VARCHAR(8000)
SELECT #Names = COALESCE(#Names + ', ', '') + Value
FROM ValueBindings
WHERE fieldid = 70297
SELECT COUNT(*), StringValue
FROM parseJSON(#Names)
WHERE NAME IN ('value', 'text')
GROUP BY StringValue
SELECT #Names
It is not returning the expected values correctly
Modify your query like below to get the desired result
SELECT COUNT(*), RTRIM(LTRIM(StringValue))
FROM parseJSON(#Names)
WHERE NAME IN ('value')
GROUP BY RTRIM(LTRIM(StringValue))
try the following:
SELECT COUNT([NAME])/2 [COUNT], LTRIM(RTRIM(StringValue)) StringValue
FROM parseJSON(#Names)
WHERE NAME IN ('value', 'text') AND [NAME] IS NOT NULL
GROUP BY LTRIM(RTRIM(StringValue))
Thanks.
SQL statement:
(select top 1 [egrp_name] from [Enotify Group] where [egrp_id] in (a.grp_id) )
e value of a.grp_id is '0,1145' and i am getting error
Conversion failed when converting the varchar value '0,1145' to data type int.
Can anybody tell me how can i change '0,1145' to 0,1145 in above case, so my query does work and also if their is any other way to do this
You can use a split-string function to change your comma delimited string into a table.
select top(1) [egrp_name]
from [Enotify Group]
where [egrp_id] in (
select Value
from dbo.SplitInts(a.grp_id)
);
One version of a split-string function that you can use if you like:
create function dbo.SplitInts(#Values nvarchar(max)) returns table with schemabinding
as
return
(
select T2.X.value(N'.', N'int') as Value
from (select cast(N'<?X '+replace(#Values, N',', N'?><?X ') + N'?>' as xml).query(N'.')) as T1(X)
cross apply T1.X.nodes(N'/processing-instruction("X")') as T2(X)
);
Or you can use like.
select top(1) [egrp_name]
from [Enotify Group]
where ','+a.grp_id +',' like '%,'+cast(egrp_id as varchar(11))+',%' ;
