Using SQL, how can I select the value for "conversion_event" from the JSON below?
{"str":[1,1342886173,100000627571405,"offsite_conversion.lead",{"action.type":"offsite_conversion","conversion_event":387756207950188,"tag":"lead"},["conversion_event"],[],{"amount":12623486},"1:11:1:0:0:1:0"]}
There are some unusual things in here, for example JSON within JSON, and the square brackets. Assume that lengths of all values vary by row, so you cannot slice by a set number of character positions.
Based on comments:
declare #astr varchar(max);
declare #start int;
declare #end int;
set #astr = '{"str":[1,1342886173,100000627571405,"offsite_conversion.lead",{"action.type":"offsite_conversion","conversion_event":387756207950188,"tag":"lead"},["conversion_event"],[],{"amount":12623486},"1:11:1:0:0:1:0"]}';
select #start = charindex('"conversion_event":',#astr)
select #end = charindex(',"tag":',#astr)
select substring(#astr,#start,#end-#start);
returns
"conversion_event":387756207950188
add
set #start = #start + 19;
to get just the number.
SELECT substring('{"str":[1,1342886173,100000627571405,"offsite_conversion.lead",{"action.type":"offsite_conversion","conversion_event":387756207950188,"tag":"lead"},["conversion_event"],[],{"amount":12623486},"1:11:1:0:0:1:0"]}',
101,16);
or
select substring('{"str":[1,1342886173,100000627571405,"offsite_conversion.lead",{"action.type":"offsite_conversion","conversion_event":387756207950188,"tag":"lead"},["conversion_event"],[],{"amount":12623486},"1:11:1:0:0:1:0"]}',
151,16)
Ok this is the structure of the object:
{
"str":[1,
1173,
10005,
"offsite_conversion.lead",
{"action.type":"offsite_conversion",
"conversion_event":387756207950188,
"tag":"lead"},
["conversion_event"],
[],
{"amount":14486},
"1:11:1:0:0:1:0"
]}
An object with an atribute str which is an array.
The 5th element has a 2nd attribute conversion event
The 6th element is an array of one element which is conversion event.
So the question is... is this structure the same and which of these do you want?

Situation: I have a column where each cell can have up to 5 delimiters. However, it's possible that there are none.
Objective: How do i handle errors such as :
Invalid length parameter passed to the LEFT or SUBSTRING function.
in the case that it cannot find the specified delimiter.
Query:
declare #text VARCHAR(111) = 'abc-def-geeee-ifjf-zzz'
declare #start1 as int
declare #start2 as int
declare #start3 as int
declare #start4 as int
declare #start_index_reverse as int
set #start1 = CHARINDEX('-',#text,1)
set #start2 = CHARINDEX('-',#text,charindex('-',#text,1)+1)
set #start3 = CHARINDEX('-',#text,charindex('-',#text,CHARINDEX('-',#text,1)+1)+1)
set #start4 = CHARINDEX('-',#text,charindex('-',#text,CHARINDEX('-',#text,CHARINDEX('-',#text,1)+1)+1)+1)
set #start_index_reverse = CHARINDEX('-',REVERSE(#text),1)
select
LEFT(#text,#start1-1) AS Frst,
SUBSTRING(#text,#start1+1,#start2-#start1-1) AS Scnd,
SUBSTRING(#text,#start2+1,#start3-#start2-1) AS Third,
SUBSTRING(#text,#start3+1,#start4-#start3-1)AS Third,
RIGHT(#text,#start_index_reverse-1) AS Lst
In this case my variable includes 5 delimiters and so my query works but if i removed one '-' it would break.
XML support in SQL Server brings about some unintentional but useful tricks. Converting this string to XML allows for some parsing that is far less messy than native string handling, which is very far from awesome.
DECLARE #test varchar(111) = 'abc-def-ghi-jkl-mnop'; -- try also with 'abc-def'
;WITH n(x) AS
(
SELECT CONVERT(xml, '<x>' + REPLACE(#test, '-', '</x><x>') + '</x>')
)
SELECT
Frst = x.value('/x[1]','varchar(111)'),
Scnd = x.value('/x[2]','varchar(111)'),
Thrd = x.value('/x[3]','varchar(111)'),
Frth = x.value('/x[4]','varchar(111)'),
Ffth = x.value('/x[5]','varchar(111)')
FROM n;
For a table it's almost identical:
DECLARE #foo TABLE ( col varchar(111) );
INSERT #foo(col) VALUES('abc-def-ghi-jkl-mnop'),('abc'),('def-ghi');
;WITH n(x) AS
(
SELECT CONVERT(xml, '<x>' + REPLACE(col, '-', '</x><x>') + '</x>')
FROM #foo
)
SELECT
Frst = x.value('/x[1]','varchar(111)'),
Scnd = x.value('/x[2]','varchar(111)'),
Thrd = x.value('/x[3]','varchar(111)'),
Frth = x.value('/x[4]','varchar(111)'),
Ffth = x.value('/x[5]','varchar(111)')
FROM n;
Results (sorry about the massive size, seems this doesn't handle 144dpi well):
add a test before your last select
then you should decide how to handle the other case (when one of start is 0)
You can also refer to this link about splitting a string in sql server
which is uses a loop and can handle any number of delimiters
if #start1>0 and #start2>0 and #start3>0 and #start4>0
select LEFT(#text,#start1-1) AS Frst,
SUBSTRING(#text,#start1+1,#start2-#start1-1) AS Scnd,
SUBSTRING(#text,#start2+1,#start3-#start2-1) AS Third,
SUBSTRING(#text,#start3+1,#start4-#start3-1)AS Third,
RIGHT(#text,#start_index_reverse-1) AS Lst
I'm trying to get all this XML result in one line instead of 3 for each column
DECLARE #ii INT = 10;
DECLARE #String1 NVARCHAR(4000);
SET #String1 = '';
WHILE(#ii <= 18)
BEGIN
SET #String1 = (#String1 + 'SELECT LoanNumber = ''Complaint'+CONVERT(VARCHAR(2),#ii)+'-Call1'' , LoanStatus=''Compliants'' , LoanStatusDate = CAST(GETDATE() AS DATE)
UNION
SELECT LoanNumber = ''Complaint'+CONVERT(VARCHAR(2),#ii)+'-Call2'', LoanStatus=''Compliants'' , LoanStatusDate = CAST(GETDATE() AS DATE)
UNION
SELECT LoanNumber = ''Complaint'+CONVERT(VARCHAR(2),#ii)+'-Call3'', LoanStatus=''Compliants'' , LoanStatusDate = CAST(GETDATE() AS DATE)')
IF #ii != 18
SET #string1 = #string1 + ' UNION '
ELSE
SET #string1 = #string1 + 'FOR XML PATH (''Loan''),ROOT(''Loans'') '
SET #ii = #ii+1
END
EXEC sp_executesql #String1
I want something like this:
<Loans>
<LoanNumber>Complaint10-Call1<LoanStatus>Compliants<LoanStatusDate>2019-01-18
</Loan>
<Loan>
<LoanNumber>Complaint10-Call2 <LoanStatus>Compliants<LoanStatusDate>2019-01-18
</Loan>
<Loan>
<LoanNumber>Complaint10-Call3<LoanStatus>Compliants<LoanStatusDate>2019-01-18
</Loan>
Instead of the result that you get when you execute the code I provided. I appreciate your help.
This might be wild guessing, but I've got the feeling, that I understand, what this is about:
if you run the code you will see the result. no input data is needed .
I just want the structure of the xml outcome to all be on one line for
one set of each loop
Your provided code leads to this:
<Loans>
<Loan>
<LoanNumber>Complaint10-Call1</LoanNumber>
<LoanStatus>Compliants</LoanStatus>
<LoanStatusDate>2019-01-22</LoanStatusDate>
</Loan>
<Loan>
<LoanNumber>Complaint10-Call2</LoanNumber>
<LoanStatus>Compliants</LoanStatus>
<LoanStatusDate>2019-01-22</LoanStatusDate>
</Loan>
<!-- more of them-->
</Loans>
This is perfectly okay, valid XML.
But you want the result
outcome to all be on one line for one set of each loop
Something like this?
<Loans>
<Loan>
<LoanNumber>Complaint10-Call1</LoanNumber><LoanStatus>Compliants</LoanStatus><LoanStatusDate>2019-01-22</LoanStatusDate>
</Loan>
<!-- more of them-->
</Loans>
There is a big misconception I think... XML is not the thing you see. The same XML can look quite differently, without any semantic difference:
Check this out:
DECLARE #xmltable table(SomeXml XML)
INSERT INTO #xmltable VALUES
--the whole in one line
('<root><a>test</a><a>test2</a></root>')
--all <a>s in one line
,('<root>
<a>test</a><a>test2</a>
</root>')
--each element in one line
,('<root>
<a>test</a>
<a>test2</a>
</root>')
--white space going wild...
,('<root>
<a>test</a>
<a>test2</a>
</root>');
--now check the results
SELECT * FROM #xmltable;
This means: How the XML appears is a matter of the interpreter. The same XML opened with another tool might appear differently. Dealing with XML means dealing with data but not with format... The actual format has no meaning and should not matter at all...
Starting with SQL-Server 2016 you might have a look at JSON, if you need a tiny format:
DECLARE #somedata table(SomeValue VARCHAR(100),SomeStatus VARCHAR(100),SomeDate DATE);
INSERT INTO #somedata VALUES
('Complaint10-Call1','Complaints','2019-01-22')
,('Complaint10-Call2','Complaints','2019-01-22')
,('Complaint10-Call3','Complaints','2019-01-22');
SELECT * FROM #somedata FOR JSON PATH;
The result comes in one line:
[{"SomeValue":"Complaint10-Call1","SomeStatus":"Complaints","SomeDate":"2019-01-22"},{"SomeValue":"Complaint10-Call2","SomeStatus":"Complaints","SomeDate":"2019-01-22"},{"SomeValue":"Complaint10-Call3","SomeStatus":"Complaints","SomeDate":"2019-01-22"}]
I have an XML column in my Table and i wanted to replace particular text wherever it appear in that column with a new text. Here is the xml structure,
<Story>
<StoryNonText>
<NonText>
<ImageID>1</ImageID>
<Src>http://staging.xyz.com/FolderName/1.png</Src>
</NonText>
<NonText>
<ImageID>2</ImageID>
<Src>http://staging.xyz.com/FolderName/2.png</Src>
</NonText>
</StoryNonText>
</Story>
In the above XML I wanted to replace all the <Src> values having http://staging.xyz.com/ to http://production.xyz.com/. Please guide me how i can do this!
You can use Replace() function as below:
Update TableName
SET
ColumnName=replace(CAST(ColumnName AS VARCHAR(8000)),'<Src>http://staging.xyz.com/','<Src>http://production.xyz.com/')
With a little help from a couple of XML functions you can do this in a loop.
The loop is necessary since replace value of can only replace one value at a time. This code assumes the URL is located first in the node and not embedded in text anywhere.
declare #T table(X xml);
insert into #T(X) values('<Story>
<StoryNonText>
<NonText>
<ImageID>1</ImageID>
<Src>http://staging.xyz.com/FolderName/1.png</Src>
</NonText>
<NonText>
<ImageID>2</ImageID>
<Src>http://staging.xyz.com/FolderName/2.png</Src>
</NonText>
</StoryNonText>
</Story> ');
declare #FromURL nvarchar(100);
declare #ToURL nvarchar(100);
set #FromURL = 'http://staging.xyz.com/';
set #ToURL = 'http://production.xyz.com/';
while 1 = 1
begin
update #T
set X.modify('replace value of (//*/text()[contains(., sql:variable("#FromURL"))])[1]
with concat(sql:variable("#ToURL"), substring((//*/text()[contains(., sql:variable("#FromURL"))])[1], string-length(sql:variable("#FromURL"))+1))')
where X.exist('//*/text()[contains(., sql:variable("#FromURL"))]') = 1;
if ##rowcount = 0
break;
end;
select *
from #T
replace value of (XML DML)
concat Function (XQuery)
contains Function (XQuery)
string-length Function (XQuery)
sql:variable() Function (XQuery)
There are many ways to do that.
The first way is to add a WHILE loop. Inside a loop, you search (CHARINDEX) for a position of first tag and first tag. Then, knowing the start and end positions, replace the value. Then on the next iteration you search again, but change starting position in CHARINDEX() function
The second way is to use SELECT ... FROM OPENXML + EXEC sp_xml_preparedocument
I'm looking to parse a sql column result into separate columns. Here is an example of the column...
Detail - Column name
'TaxID changed from "111" to "333". Address1 changed from "542 Test St." to "333 Test St". State changed from "FL" to "DF". Zip changed from "11111" to "22222". Country changed from "US" to "MX". CurrencyCode changed from "usd" to "mxn". RFC Number changed from "" to "test". WarehouseID changed from "6" to "1". '
I need to take the old TAXID, new TAXID, old country, and new country and put them in separate columns.
The Detail column will always have TAXID and Country, however the challenging part is that they don't always have the rest of data that I listed above. Sometimes it will contain city and other times it won't. This means the order is always different.
I would create a tsql proc, use a case statement.
Do a count of the double quotes. If there are 8 oairs, you know that you old and new values, only 4 pairs you only have new values.
Then using the double quotes as indexes for your substring, you can put the vales into the table.
Good luck!
I was able to come up with something that worked.
In case anyone else gets a situation like this again perhaps posting my code will help.
DECLARE #document varchar(350);
set #document = 'TaxID changed from "111" to "222"'
declare #FIRSTQUOTE int
declare #SECONDQUOTE int
declare #OLDTAXID nvarchar(40)
declare #firstlength int
declare #ThirdQuote int
declare #FourthQuote int
declare #secondlength int
declare #NewTAXID nvarchar(40)
declare #oneplussecondquote int
declare #oneplusthirdquote int
select #FirstQuote = CHARINDEX('"',#document)
set #FIRSTQUOTE = #FIRSTQUOTE + 1
select #SECONDQUOTE = CHARINDEX('"',#document,#FIRSTQUOTE)
set #firstlength = #SECONDQUOTE - #FIRSTQUOTE
select #OLDTAXID = SUBSTRING(#document,#FIRSTQUOTE,#firstlength)
set #oneplussecondquote = #SECONDQUOTE + 1
select #ThirdQuote = CHARINDEX('"',#document,#oneplussecondquote)
set #oneplusthirdquote = #ThirdQuote + 1
select #FourthQuote = CHARINDEX('"',#document,#oneplusthirdquote)
select #secondlength = #FourthQuote - #oneplusthirdquote
select #NewTAXID = SUBSTRING(#document,#oneplusthirdquote,#secondlength)
You can switch out the string for this: 'Country changed from "US" to "MX"'
And it would grab the old country and new country
I am writing a stored proc that calculates a WHOLE bunch of different things, but I have a bit in it, that is repeated about 9 times.
eg:
if #argA = 1 (true)
select Count(samples) from dbo.X where type = #argAType
if #argB = 1 (true)
select Count(samples) from dbo.X where type = #argBType
if #argC = 1
select Count(samples) from dbo.X where type = #argCType
and so on...
how can I write a function (or something similar) that I can pass in a bit (true or false), and other argument, and only return the result set if true???
Is this what you're looking for? This is the best I can deduce based on the question as it's currently posted.
SELECT COUNT(samples)
FROM dbo.X
WHERE
(type=#argAType AND #argA=1)
OR
(type=#argBType AND #argB=1)
OR
(type=#argCType AND #argC=1)
In function form, I think this is right:
CREATE FUNCTION GetCount(#n AS BIGINT) RETURNS BIGINT
AS
BEGIN
DECLARE #count BIGINT
SELECT #count = COUNT(samples)
FROM dbo.X
WHERE
(type=#argAType AND #argA=1)
OR
(type=#argBType AND #argB=1)
OR
(type=#argCType AND #argC=1)
RETURN #count
END
