I have copied the code somewhere in the internet and have created an html table using something like
''FOR XML RAW (''TR''), ELEMENTS, TYPE) AS ''TBODY''',
' FOR XML PATH (''''), ROOT (''TABLE'')'`
in SQL. The result is as expected which is an HTML table, below is the snippet.
Can someone point me on how to get the HTML string and save it into a column in my table. My thought was to get the result and save it as a string then insert it into a column in my table but after sometimes I failed.
The code example can be retrieve from https://www.mssqltips.com/sqlservertip/5025/stored-procedure-to-generate-html-tables-for-sql-server-query-output/
Cheers!! it's simple but I went around the globe. What I did was adding SET #Myvariable = in the dynamic query. Previously, I have tried so hard to assign the result into a variable outside the dynamic query which will never work for me.
Originally:
SET #DynTSQL = CONCAT (
'SELECT (SELECT '
, #columnslist
,' '
, #restOfQuery
,' FOR XML RAW (''TR''), ELEMENTS, TYPE) AS ''TBODY'''
,' FOR XML PATH (''''), ROOT (''TABLE'')'
)
What I did:
SET #DynTSQL = 'SET #SQLQuery1 =('+CONCAT (
'SELECT (SELECT '
, #columnslist
,' '
, #restOfQuery
,' FOR XML RAW (''TR''), ELEMENTS, TYPE) AS ''TBODY'''
,' FOR XML PATH (''''), ROOT (''TABLE'')'
)+')'
The result will be assigned into the #SQLQuery1.
Cheers!!!

I've been playing around with Substring, left, right, charindex and can't quite get this to work
If this is the value in column name 'Data' (this is all one line)
{"email":{"RecipientId":"usertest","RecipientEmail":"test#test.com","Subject":"This is a test subject heading","RecipientSubject":"A recipient subject"}}
How do I do a SELECT statement to find the 'Subject' heading and then get the data 'This is a test subject'? The Subject value is different for every record so I just can't look for 'This is a test subject'.
So the end result should be This is a test subject for that SELECT result
The following query should do what you want:
declare #string varchar(max);
set #string = '{"email":{"RecipientId":"usertest","RecipientEmail":"test#test.com","Subject":"This is a test subject heading","RecipientSubject":"A recipient subject"}}';
select substring(#string,charindex('"Subject":',#string)+11,charindex('"RecipientSubject"',#string)-charindex('"Subject"',#string)-13);
The plain and easy-cheesy approach is this:
SELECT SUBSTRING(
t.YourString
,A.StartPosition
,CHARINDEX('"'
,t.YourString
,A.StartPosition+1) - A.StartPosition
)
FROM #dummyTable t
CROSS APPLY(SELECT CHARINDEX('"Subject":"',t.YourString)+11) A(StartPosition)
I use APPLY to calculate a value and use it like you'd use a variable. The idea is: Find the starting point and look for the closing quote from there. But this will break, whenever the content includes an (escaped) quote like in
"Subject":"This is \"quoted\" internally"
A more generic approach
Starting with v2016 JSON-support was introduced. With this (or a higher) version this is really simple:
Use this mockup-table for testing
DECLARE #dummyTable TABLE (YourString VARCHAR(1000));
INSERT INTO #dummyTable VALUES('{"email":{"RecipientId":"usertest","RecipientEmail":"test#test.com","Subject":"This is a test subject heading","RecipientSubject":"A recipient subject"}}');
--The OPENJSON-method will read this for you:
SELECT JsonContent.*
FROM #dummyTable t
CROSS APPLY OPENJSON(t.YourString,'$.email')
WITH(RecipientId VARCHAR(100)
,RecipientEmail VARCHAR(100)
,[Subject] VARCHAR(100)
,RecipientSubject VARCHAR(100)) JsonContent;
But with a lower version you will need to trick this out. It is the easiest, to tranform JSON to attribute centered XML like here:
<email RecipientId="usertest" RecipientEmail="test#test.com" Subject="This is a test subject heading" RecipientSubject="A recipient subject" />
We can achieve this by some string methods and I must warn you, that there are several pit-falls with forbidden characters and other stuff... Just try it out:
SELECT Casted.ToXml.value('(/email/#RecipientId)[1]','varchar(1000)') AS RecipientId
,Casted.ToXml.value('(/email/#RecipientEmail)[1]','varchar(1000)') AS RecipientEmail
,Casted.ToXml.value('(/email/#Subject)[1]','varchar(1000)') AS [Subject]
,Casted.ToXml.value('(/email/#RecipientSubject)[1]','varchar(1000)') AS RecipientSubject
,Casted.ToXml.query('.') LookHowThisWasTransformed
FROM #dummyTable t
CROSS APPLY
(
SELECT CAST(CONCAT('<email '
,REPLACE(REPLACE(REPLACE(REPLACE(t.YourString,'{"email":{"',''),'}}',''),'","','" '),'":"',' ="')
,' />') AS XML)
) Casted(ToXml);
I need to gather data from two columns, concat them so that it's only the first six of the first column and the last six of the second column, separated by ' + '. Some have been input with weird spaces in front or in back, so we must also use the trim feature and get rid of all NULL. I haven't had any issues with the first part, but am struggling to use the trim feature in a way that gives the desired output.
Output needs to look like this:
Input Data sample:
The following code returns results, but the output doesn't match so I know the trim is wrong:
SELECT CONCAT(SUBSTRING(baseball, 1, 6), ' + ',
SUBSTRING(football, -6)) AS MYSTRING
FROM datenumtest2
WHERE baseball IS NOT NULL AND football IS NOT NULL;
I also tried the following, but get an error message about the parameters being incorrect:
SELECT CONCAT(SUBSTRING(LTRIM(baseball, 1, 6)), ' + ',
SUBSTRING(RTRIM(football, -6))) AS MYSTRING
FROM datenumtest2
WHERE baseball IS NOT NULL AND
football IS NOT NULL;
I'm still new to this site and learning, but I have tried to include as much as I can! If there is other information that I can add to help, please let me know.
You just need to use Trim() on the column(s), before using Substring() function on them:
SELECT CONCAT(SUBSTRING(TRIM(baseball), 1, 6), ' + ',
SUBSTRING(TRIM(football), -6)) AS MYSTRING
FROM datenumtest2
WHERE baseball IS NOT NULL AND
football IS NOT NULL;
I want to upload the contents of a CSV file as new values in Exact Online data set using for instance the following SQL statement:
update exactonlinerest..ItemWarehouses
set maximumstock=0
where id='06071a98-7c74-4c26-9dbe-1d422f533246'
and maximumstock != 0
I can retrieve the contents of the file using:
select *
from files('C:\path\SQLScripts', '*.csv', true)#os fle
join read_file_text(fle.file_path)#os
But seem unable to change the multi-line text in the file_contents field to separate lines or records.
How can I split the file_contents's field into multi lines (for instance using 'update ...' || VALUE and then running it through ##mydump.sql or directly using insert into / update statement)?
For now I've been able to solve it using regular expressions and then loading generated SQL statement into the SQL engine as follows:
select regexp_replace(rft.file_contents, '^([^,]*),([^,]*)(|,.*)$', 'update exactonlinerest..ItemWarehouses set maximumstock = $1 where code = $2 and maximumstock != $1;' || chr(13), 1, 0, 'm') stmts
, 'dump2.sql' filename
from files('C:\path\SQLScripts', '*.csv', true)#os fle
join read_file_text(fle.file_path)#os rft
local export documents in stmts to "c:\path\sqlscripts" filename column filename
#c:\hantex\path\dump2.sql
However, it is error prone when I have a single quote in the article code.
I've looked for the past hour online to find an answer specific to my situation, but none have solved my question. I am trying to query a MySQL database (which I have done successfully) and then output the results to a text file.
I have read that using bcp and "queryout" are the best methods of achieving this goal. My code is below, but it continues to give me the following errors: "Incorrect Syntax Near 'L'.".
How do I fix this? Is there an easier way to export my results from Visual Studio to a text file?
set #logtext =
'"
SELECT category, occurTime, sourceKeyName, recipe, "value", formulaName, startTime, endTime , BatchID
FROM dbo.Batch
LEFT JOIN dbo.BatchHeader ON Batch.uniqueBatchID = BatchHeader.uniqueBatchID
LEFT JOIN dbo.RecipeHeader ON BatchHeader.uniqueBatchID = RecipeHeader.uniqueBatchID
LEFT JOIN dbo.BReportEvent ON RecipeHeader.uniqueBatchID = BReportEvent.uniqueBatchID
LEFT JOIN dbo.RecipeFormula ON BReportEvent.uniqueBatchID = RecipeFormula.uniqueBatchID
WHERE category = 'L-FAIL-MSG'
AND occurTime >= DATEADD(day, -1, GETDATE())
AND "value" != ' '
"'
DECLARE #logtext varchar(1000)
DECLARE #cmd varchar(2000)
SET #cmd = 'bcp ' + #logtext + ' queryout "C:\Users\anduaguibe\Documents\Visual Studio 2017\Projects\HelloWorld\HelloWorld\upstreamData.txt" -U uID -P uPass -c'
EXEC master...XP_CMDSHELL #cmd
bcp has always worked for me when pushing result sets out to a file, so that's good, as far as I can see.
The bigger problem here is how you're formatting the #logtext query string; You need to escape out the single quote by adding a second one before it. Here are a couple of problem spots for you:
WHERE category = 'L-FAIL-MSG'
and
AND ''value'' != ' '
In the first instance, you're giving it a string and then a literal and then another string, without any formatting.
You need to either add that second quote to escape it and treat L-FAIL-MSG as a string literal, or make L-FAIL-MESSAGE a variable push that into the string.
The second instance will give you an issue, because you've again not escaped the quote- it appears to be a string followed by another string without any operators to concatenate them or anything.
Here's how it might need to be formatted
WHERE category = ''L-FAIL-MSG''
and
AND ''value'' != '' ''
I need to take a postal code looking like:
S7Y 6H5
that's in a table and display it as
S7Y & 6H5
I can't find a command that splits the string in sql.
MySQL doesn't include a split function, but it does include a replace. You could use:
SELECT REPLACE('S7Y 6HS', ' ', ' & ')
The greater question for me, though, is why don't you do that in your application code?
Try this:
Select REPLACE ('S7Y 6H5', ' ', ' & ')
you can use INSERT INSERT(str,pos,len,newstr)
SELECT INSERT('S7Y 6H5', 4, 0, ' & ');
