replacing XML tag value within a large XML text value MSSQL.
Within MSSQL I have a column called form which is a text column with an extremely large XML. I need to find a certain tag and change the value of that sub tag within the tag from False to True.
This is what I currently have:
USE trainset;
UPDATE dbo.users
SET formxml = REPLACE(CAST(formxml as nvarchar(max)), '%<ttaycheckbox><name>cbTermsConditions</name><cargo>F</cargo></ttaycheckbox>%', '<ttaycheckbox><name>cbTermsConditions</name><cargo>T</cargo></ttaycheckbox>')
WHERE usersid = '0000GARX'
and formname ='ffOrderRpt'
and formxml LIKE ('%<ttaycheckbox><name>cbTermsConditions</name><cargo>F</cargo></ttaycheckbox>%')
It seems like it is doing the update;
However, after this when I do a select on this particular value the value of is still False rather than True.
What am I missing in there that is not causing it to update properly?
replace() doesn't support wildcards. So your where ... like finds the relevant records, but replace finds NOTHING, because it's looking for a literal %.
You can use XML modify and exist:
UPDATE users
SET formxml.modify('replace value of (/ttaycheckbox/cargo/text())[1] with "T"')
WHERE usersid = '0000GARX'
and formname ='ffOrderRpt'
and formxml.exist('/ttaycheckbox/name[text()[1] eq "cbTermsConditions"]') = 1
and formxml.exist('/ttaycheckbox/cargo[text()[1] eq "F"]') = 1

I have an nvarchar field in my database called CatCustom which contains comma-separated 5-character codes. It can contain as little as one code, or as many as 20 codes, separated by commas.
Right now, I use this query to add a new 5-character code to the field in given records (in this case the new code is LRR01):
UPDATE dbo.Sources
SET CatCustom = CONCAT_WS(', ', RTRIM(CatCustom), 'LRR01')
WHERE SourceID IN (1,2,3,4,5,8,9,44,63,45,101,102,222,344)
I need to add to this though: I need the record to be updated only if that 5-character code doesn't already exist somewhere in the CatCustom field, to ensure that code is not in there more than once.
How would I accomplish this?
EDIT: I really don't understand how this can be considered a duplicate of the suggested thread. This is a VERY specific case and has nothing to do with creating stored procedures and or variables. The alleged duplicated thread does not really help me - sorry.
Use STRING_SPLIT function to split the comma separated list and then add Not Exist condition in the WHERE clause like below
UPDATE dbo.Sources
SET CatCustom = CONCAT_WS(', ', RTRIM(CatCustom), 'LRR01')
WHERE SourceID IN (1,2,3,4,5,8,9,44,63,45,101,102,222,344)
AND NOT EXISTS (SELECT 1 FROM STRING_SPLIT(CatCustom, ',') where value = 'LRR01')
UPDATE dbo.Sources
SET
CatCustom = CONCAT_WS(', ', RTRIM(CatCustom), 'LRR01')
WHERE
SourceID IN (1,2,3,4,5,8,9,44,63,45,101,102,222,344)
AND CatCustom NOT LIKE '%LRR01%';
Context: I'm scraping some XML form descriptions from a Web Services table in hopes of using that name to identify what the user has inputted as response. Since this description changes for each step (row) of the process and each product I want something that can evaluate dynamically.
What I tried: The following was quite useful but it returns a dynamic attribute query result in it's own field ans using a coalesce to reduce the results as one field would lead to it's own complications: Get values from XML tags with dynamically specified data fields
Current Attempt:
I'm using the following code to generate the attribute name that I will use in the next step to query the attribute's value:
case when left([Return], 5) = '<?xml'
then lower(cast([Return] as xml).value('(/response/form/*/#name)[1]','varchar(30)'))
else ''
end as [FormRequest]
And as part of step 2 I have used the STUFF function to try and make the row-level query possible
case when len(FormRequest)>0
then stuff( ',' + 'cast([tmpFormResponse] as xml).value(''(/wrapper/#' + [FormRequest] + ')[1]'',''varchar(max)'')', 1, 1, '')
else ''
end as [FormResponse]
Instead of seeing 1 returned as my FormReponse feild value for the submit attribute (please see in yellow below) it's returning the query text -- cast([tmpFormResponse] as xml).value('(/wrapper/#submit)1','varchar(max)') -- instead (that which should be queried).
How should I action the value method so that I can dynamically strip out the response per row of XML data in tmpFormResponse based on the field value in the FormRequest field?
Thanx
You can check this out:
DECLARE #xml XML=
N'<root>
<SomeAttributes a="a" b="b" c="c"/>
<SomeAttributes a="aa" b="bb" c="cc"/>
</root>';
DECLARE #localName NVARCHAR(100)='b';
SELECT sa.value(N'(./#*[local-name()=sql:variable("#localName")])[1]','nvarchar(max)')
FROM #xml.nodes(N'/root/SomeAttributes') AS A(sa)
Ended up hacking up a solution to the problem by using PATINDEX and CHARINDEX to look for the value in the [FormRequest] field in the he tmpFormResponse field.
Need help to get jsob_set working under PostgreSQL procedure,
Fetching records from child table and updating parent table's json fields value.
Assigning selected value to the variable and adding it to jsonb_set under value,
e.g
jsonb_set(jsonFieldOfDb,'{json_Column}',jsonVariable,true);
Where jsonVariable is my selected value from second table.
For more detail please look at screenshot attached.
You might need to cast the path & jsonVariable to text[] and jsonb
jsonb_set(jsonFieldOfDb,'{json_Column}'::text[],jsonVariable::jsonb,true)
if your jsonVariable is just a plain string, you might need to quote them as well
jsonb_set(jsonFieldOfDb,'{json_Column}'::text[],('"' || jsonVariable || '"')::jsonb, true)
Adding to Yurui's answer, if you want to set a dynamic value other than string, you can convert the dynamic variable to jsonb by using to_jsonb function like this:
UPDATE event AS e
SET source_json = jsonb_set(source_json, '{consumerId}'::text[], to_jsonb(p.promoter_id))
FROM promoter AS p
WHERE e.id = p.event_id and p.app_id in ('123');
i have a table on sql like this:
CD_MATERIAL | CD_IDENTIFICACAO
1 | 002323
2 | 00322234
... | ...
AND SO ON (5000+ lines)
I need to use that info to search and replace multiple external xml files on a folder (all the tags on those XML had numbers like the CD_IDENTIFICACAO from sql query, i need to replace with corresponding cd_material from sql query "ex.: 002323 becomes 1)
I used this query to extract all the cd_identificacao to use on Notepad++:
declare #result varchar(max)
select #result = COALESCE(#result + '', '') + CONCAT('(',CD_IDENTIFICACAO,')|') from TBL_MATERIAIS WHERE CD_IDENTIFICACAO <> '' ORDER BY CD_MATERIAL
select #result
That would bring me ex.:
(1TEC45D025)|(1TEC800039)|(999999999)|(542251)|(2TEC58426)|(234852)
and changed the parameters to get the replace ex.:
(? 2000)|(? 2001)|(? 2002)|(? 2003)|(? 2004)|(? 2005)
but i don't know how to add a number (increment) on front of "?" so notepad++ would understand it (search and replace would have 5000+ results, so it's not pratical to manually add the increment).
I was able to get a workaround for this. I've used this query to get all the the terms for find and replace i needed (1 per line)
select concat('<cProd>',cd_identificacao,'</cProd>'), concat('<cProd>',cd_material,'</cProd>') from tbl_materiais where cd_identificacao <> '' order by cd_material
That would result in:
<cProd>1TEC460054</cProd> <cProd>1</cProd>
<cProd>1TEC240035</cProd> <cProd>2</cProd>
(i added the tag too to make sure no other information could be replaced as there were many number combinations that could lead to incorrect replacement)
then pasted it on a txt and i used the notepad++ to replace the space between column 1 and 2 for /r/n wich would result in:
<cProd>1TEC460054</cProd>
<cProd>1</cProd>
<cProd>1TEC240035</cProd>
<cProd>2</cProd>
then i used "Ecobyte Replace Text" Tool, pasted my result file as new selection in bottom frame, loaded all my files on a new replace group on top frame (on properties of the group, u can change directory and options), then executed the replacement, it worked perfectly.
Thx.
I am working on a stored procedure which shreds an XML document. One of the child elements in the records being processed can sometimes be marked with the xsi:nil="true" attribute. Other times, it can contain a dateTime. I'm trying to insert a string into a column of my table which depends on whether or not this element has a value. For example:
[Status] = CASE WHEN (Rt.Item.value('(./Date)[1]', 'nvarchar(max)') = '') THEN N'SUBMITTED' ELSE N'PROCESSED' END
Unfortunately, this doesn't seem to be working. What's the correct to check if an element has a value in SQL Server?
Generally:
theElementName[not(#xsi:nil eq 'true')]/any/other/needed/location/steps
If the association of the "xsi" prefix to the appropriate namespace isn't registered (the way to do this is implementation-specific and you need to check how this is to be done in your situation), one still can use:
theElementName[not(#*[name() eq 'xsi:nil'] eq 'true')]
