I have string data in one cell and column type text.
like example :
Q: {"newColumnName":"xxxx","filterList":[],"columnNames":"pqrs"}
columnNames,filterList,newColumnName are not in fixed position may be change.
i need to replace this above string data to
Need Result:{"columnNames":["pqrs"],"filterList":[],"parameters":{"newColumnName":"xxxx"}}
means i need to search and replace :-
1. "columnNames":"pqrs"------>"columnNames":["pqrs"].
2. "newColumnName":"xxxx" ------>"parameters":{"newColumnName":"xxxx"}.
pqrs and xxxx known to me. It can any string in there.
you can do it with a query like this:
It is ONLY a text replacement
to check
SELECT t.val
, REPLACE(
REPLACE(t.val,'"columnNames":"pqrs"','"columnNames":["pqrs"]')
, '"newColumnName":"xxxx"' , '"parameters":{"newColumnName":"xxxx"}') as result
FROM tt t;
to replace
UPDATE tt
set tt.val =
REPLACE(
REPLACE(tt.val,'"columnNames":"pqrs"','"columnNames":["pqrs"]')
, '"newColumnName":"xxxx"' , '"parameters":{"newColumnName":"xxxx"}');
I need to search and replace this html in a mysql database ( via phpMyAdmin ) :
<tr>
<td></td>
<td></td>
</tr>
But I don't know how to find it, as it has line breaks.
My current query is :
UPDATE `wp_posts`
SET `post_content` = replace(post_content, '<tr>
<td></td>
<td></td>
</tr>', '')
But obviously, it's not working.
How can I target it ?
you can use REGEXP_REPLACE. Please note that the provided regex both works for windows and linux style newlines. please also note that possible use of spaces are also considered in regex.
REGEXP_REPLACE(x, '<tr>(\s*\r*\n*\s*<td>\s*\r*\n*\s*</td>){2}\s*\r*\n*\s*</tr>', '<<replaced>>' )
\n is linux style newline
\r\n is windows style newline
\s is space character
create table t (x varchar(1000));
✓
insert into t values ('before <tr>\n<td></td>\n<td></td>\n</tr> after')
✓
select * from t
| x |
| :--------------------------------------------------- |
| before <tr><br><td></td><br><td></td><br></tr> after |
select REGEXP_REPLACE(x, '<tr>(\s*\r*\n*\s*<td>\s*\r*\n*\s*</td>){2}\s*\r*\n*\s*</tr>', '<<replaced>>' ) from t
| REGEXP_REPLACE(x, '<tr>(\s*\r*\n*\s*<td>\s*\r*\n*\s*</td>){2}\s*\r*\n*\s*</tr>', '<<replaced>>' ) |
| :------------------------------------------------------------------------------------------------ |
| before <<replaced>> after |
update t set x = REGEXP_REPLACE(x, '<tr>(\s*\r*\n*\s*<td>\s*\r*\n*\s*</td>){2}\s*\r*\n*\s*</tr>', '<<replaced>>' )
✓

If you are looking to replace a string made of 4 lines, one thing you need to be careful about is line breaks. For example in your query you have additional spaces at the beginning of lines 2, 3 and 4, that probably will not match.
Depending on your set up, line breaks could be \r\n or \n.
UPDATE `wp_posts`
SET `post_content` = REPLACE(
post_content,
'<tr>\n<td></td>\n<td></td>\n</tr>',
''
)
If you are looking to replace 4 different strings, then you could either run the updates one by one, or generate a 4-level deedp nested REPLACE(). Here are examples for two string parts :
UPDATE `wp_posts` SET `post_content` = REPLACE(post_content, '<tr>', '');
UPDATE `wp_posts` SET `post_content` = REPLACE(post_content, '<td></td>', '');
Or :
UPDATE `wp_posts`
SET `post_content` =
REPLACE(
REPLACE(
post_content,
'<td></td>',
''
),
'<tr>',
''
)
;
I am using html code in my SQL Script to output results from a table in an email, but I need to change the color of the text if any of the results come back as specific string. Here is a snippet of what I'm using to produce the table:
'<table border="2">' +
'<tr>
<th>No#</th>
<th>SERVER NAME</th>
<th>SERVER IP</th>
<th>STATUS </th>
</tr>' +
CAST (( SELECT DISTINCT
td = [NUMBER], '',
td = [SERVER NAME], '',
td = [SERVER IP], '',
td = [STATUS], ''
FROM SUMMARY
FOR XML PATH('tr'), TYPE
) AS VARCHAR(MAX) ) +
'</table>';
So I am concerned about the "STATUS" Field, if it comes back SUCCESS it could stay as regular text, if it says BAD then I want it to be Red.... I have tried putting in the <font color=""> tag but it only changes the Headers (between the TH tags)..
No# SERVER NAME SERVER IP STATUS
1 SERVER1 10.10.10.1 BAD --this should be red
2 SERVER2 10.10.10.2 SUCCESS
3 SERVER3 10.10.10.3 BAD --this should be red
4 SERVER4 10.10.10.4 SUCCESS
Like the commenter noted, you should really not be doing this. If you really want to, you will need to do it outside the query, since SQL will treat all query data as text and escape the HTML characters in order to display them as text.
A simple (but "ugly-ish") solution is to simply do a replace like this:
REPLACE('<table border="2">' +
'<tr>
<th>No#</th>
<th>SERVER NAME</th>
<th>SERVER IP</th>
<th>STATUS </th>
</tr>' +
CAST (( SELECT DISTINCT
td = [NUMBER], '',
td = [SERVER NAME], '',
td = [SERVER IP], '',
td = [STATUS], ''
FROM SUMMARY
FOR XML PATH('tr'), TYPE
) AS VARCHAR(MAX) ) +
'</table>', '>BAD<', '><font color="red">BAD</font><')
I need to write SQL statement that will return an html table and specify font size to its content.
I've found some information here. Solusion of this tipic describes how to get XML with elements but without attributes:
<tr>
<th>Problem</th>
<th>Onset</th>
<th>Status</th>
</tr>
<tr>
<td>aaa</td>
<td>bbb</td>
<td>ccc</td>
</tr>
But I need to write SQL statement that would return something like this:
<tr>
<th><font size="1">Problem</font></th>
<th><font size="1">Onset</font></th>
<th><font size="1">Status</font></th>
</tr>
<tr>
<td><font size="1">aaa</font></td>
<td><font size="1">bbb</font></td>
<td><font size="1">ccc</font></td>
</tr>
A couple thoughts.
1) Convert your SQL data to XML in your application, not in the query. .NET / PHP / Java all have ways to get SQL data as XML.
2) Use XSL to transform the XML from the database to HTML
3) Consider using CSS instead of <font> tags.
table td {
FONT-SIZE: 12px;
}
declare #T table
(
ProblemType varchar(10),
Onset date,
DiagnosisStatus varchar(10)
)
insert into #T values
( 'Ulcer', '01/01/2008', 'Active'),
( 'Edema', '02/02/2005', 'Active')
select
(select 1 as 'th/#size', 'Problem' as th for xml path(''), type),
(select 1 as 'th/#size', 'Onset' as th for xml path(''), type),
(select 1 as 'th/#size', 'Status' as th for xml path(''), type)
union all
select
(select 1 as 'td/#size', p.ProblemType as 'td' for xml path(''), type),
(select 1 as 'td/#size', p.Onset as 'td' for xml path(''), type),
(select 1 as 'td/#size', p.DiagnosisStatus as 'td' for xml path(''), type)
from #T p
for xml path('tr')
Result:
<tr>
<th size="1">Problem</th>
<th size="1">Onset</th>
<th size="1">Status</th>
</tr>
<tr>
<td size="1">Ulcer</td>
<td size="1">2008-01-01</td>
<td size="1">Active</td>
</tr>
<tr>
<td size="1">Edema</td>
<td size="1">2005-02-02</td>
<td size="1">Active</td>
</tr>
I'm creating a HL7 Continuity of Care Document (CCD) using FOR XML statements in SQL Server 2008 R2.
I've done A LOT with this method, but this is the first time I have to represent part of the data in a HTML table, which is giving me trouble.
So, I have the following information in a table:
Problem | Onset | Status
---------------------------------
Ulcer | 01/01/2008 | Active
Edema | 02/02/2005 | Active
and I'm trying to render the following
<tr>
<th>Problem</th>
<th>Onset</th>
<th>Status</th>
</tr>
<tr>
<td>Ulcer</td>
<td>01/01/2008</td>
<td>Active</td>
</tr>
<tr>
<td>Edema</td>
<td>02/02/2005</td>
<td>Active</td>
</tr>
I'm using this query:
SELECT p.ProblemType AS "td"
, p.Onset AS "td"
, p.DiagnosisStatus AS "td"
FROM tblProblemList p
WHERE p.PatientUnitNumber = #PatientUnitNumber
FOR XML PATH('tr')
And I keep getting the following:
<tr>
<td>Ulcer2008-01-01Active</td>
</tr>
<tr>
<td>Edema2005-02-02Active</td>
</tr>
Anyone got any advice?
select
(select p.ProblemType as 'td' for xml path(''), type),
(select p.Onset as 'td' for xml path(''), type),
(select p.DiagnosisStatus as 'td' for xml path(''), type)
from tblProblemList p
where p.PatientUnitNumber = #PatientUnitNumber
for xml path('tr')
To add the header as well you can use union all.
select
(select 'Problem' as th for xml path(''), type),
(select 'Onset' as th for xml path(''), type),
(select 'Status' as th for xml path(''), type)
union all
select
(select p.ProblemType as 'td' for xml path(''), type),
(select p.Onset as 'td' for xml path(''), type),
(select p.DiagnosisStatus as 'td' for xml path(''), type)
from tblProblemList p
where p.PatientUnitNumber = #PatientUnitNumber
for xml path('tr')
Mikael's answer works but so will this:
Rather than using FOR XML PATH('tr'), use FOR XML RAW('tr'), ELEMENTS. This will prevent the values from being concatenated and give you very clean output. Your query would look like this:
SELECT p.ProblemType AS td,
p.Onset AS td,
p.DiagnosisStatus AS td
FROM tblProblemList p
WHERE p.PatientUnitNumber = #PatientUnitNumber
FOR XML RAW('tr'), ELEMENTS
I prefer to append the header row using pure markup so I can have a little better control over what is happening. The full code block would look something like this:
DECLARE #body NVARCHAR(MAX)
SET #body = N'<table>'
+ N'<tr><th>Problem</th><th>Onset</th><th>Status</th></tr>'
+ CAST((
SELECT p.ProblemType AS td,
p.Onset AS td,
p.DiagnosisStatus AS td
FROM tblProblemList p
WHERE p.PatientUnitNumber = #PatientUnitNumber
FOR XML RAW('tr'), ELEMENTS
) AS NVARCHAR(MAX))
+ N'</table>'
EDIT
I wanted to add some extra value that I came up based on the need to format the output table.
The "AS td" alias will produce <td>value</td> elements in the markup but not because it understands that a table cell is a td. This disconnect allows us to create fake HTML elements that can be later updated after the query has been executed. For instance, if I wanted to the ProblemType value to be center aligned I can tweak the element name to allow for this. I can't add a style or class to the element name because it breaks alias naming conventions in SQL, but I can create a new element name such as tdc. This will produce <tdc>value</tdc> elements. While this is not valid markup in any way, it is easy for a replace statement to handle.
DECLARE #body NVARCHAR(MAX)
SET #body = N'<table>'
+ N'<tr><th>Problem</th><th>Onset</th><th>Status</th></tr>'
+ CAST((
SELECT p.ProblemType AS tdc,
p.Onset AS td,
p.DiagnosisStatus AS td
FROM tblProblemList p
WHERE p.PatientUnitNumber = #PatientUnitNumber
FOR XML RAW('tr'), ELEMENTS
) AS NVARCHAR(MAX))
+ N'</table>'
SET #body = REPLACE(#body, '<tdc>', '<td class="center">')
SET #body = REPLACE(#body, '</tdc>', '</td>')
This will create cell elements with the format <td class="center">value</td>. A quick block at the top of the string and you'll have center aligned values with a simple tweak.
Another situation I needed to solve was inclusion of links in the markup. As long as the value in the cell is the value you need in the href this is pretty easy to solve. I'll expand the example to include an ID field that I want linked to a detail URL.
DECLARE #body NVARCHAR(MAX)
SET #body = N'<table>'
+ N'<tr><th>Problem</th><th>Onset</th><th>Status</th></tr>'
+ CAST((
SELECT p.ID as tda
p.ProblemType AS td,
p.Onset AS td,
p.DiagnosisStatus AS td
FROM tblProblemList p
WHERE p.PatientUnitNumber = #PatientUnitNumber
FOR XML RAW('tr'), ELEMENTS
) AS NVARCHAR(MAX))
+ N'</table>'
SET #body = REPLACE(#body, '<tda>', '<td><a href="http://mylinkgoeshere.com/id/')
SET #body = REPLACE(#body, '</tda>', '">click-me</a></td>')
This example doesn't account for using the value in the cell inside of the link text but that is a solvable problem with some CHARINDEX work.
My final implementation of this system was for sending HTML emails based on SQL queries. I had a repeated need for cell alignment and common link types so I moved the replace functions into a shared scalar function in SQL so I didn't have to have them in all my stored procedures that sent email.
I hope this adds some value.
This is a generic solution with a FUNCTION on XML-base using FLWOR
It will transform any SELECT into a XHTML table.
It works (tested) with 2008R2+, but I'm pretty sure this would work on 2008, might be even on 2005, too. If someone wants to verify this, please leave a comment. Thx
The following function replaces all the various functions I provided before (see the previous version if needed)
CREATE FUNCTION dbo.CreateHTMLTable
(
#SelectForXmlPathRowElementsXsinil XML
,#tblClass VARCHAR(100) --NULL to omit this class
,#thClass VARCHAR(100) --same
,#tbClass VARCHAR(100) --same
)
RETURNS XML
AS
BEGIN
RETURN
(
SELECT #tblClass AS [#class]
,#thClass AS [thead/#class]
,#SelectForXmlPathRowElementsXsinil.query(
N'let $first:=/row[1]
return
<tr>
{
for $th in $first/*
return <th>{if(not(empty($th/#caption))) then xs:string($th/#caption) else local-name($th)}</th>
}
</tr>') AS thead
,#tbClass AS [tbody/#class]
,#SelectForXmlPathRowElementsXsinil.query(
N'for $tr in /row
return

if(empty($td/#link))
then <td>{$td/#class}{string($td)}</td>
else <td>{$td/#class}{string($td)}</td>
}
</tr>') AS tbody
FOR XML PATH('table'),TYPE
)
END
GO
The easiest call
A mock-up table with some values
DECLARE #tbl TABLE(ID INT, [Message] VARCHAR(100));
INSERT INTO #tbl VALUES
(1,'Value 1')
,(2,'Value 2');
--The call must enclose the SELECT ... FOR XML in paranthesis!
--click run snippet to see the result!
SELECT dbo.CreateHTMLTable
(
(SELECT * FROM #tbl FOR XML PATH('row'),ELEMENTS XSINIL)
,NULL,NULL,NULL
);
<table>
<thead>
<tr>
<th>ID</th>
<th>Message</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Value 1</td>
</tr>
<tr>
<td>2</td>
<td>Value 2</td>
</tr>
</tbody>
</table>
If you need headers with blanks
If your table contains a column with a blank in its name, or if you want to set a column's caption manually (multi langugage support!), or if you want to replace a CamelCaseName with an out-written caption, you can pass this as attribute:
DECLARE #tbl2 TABLE(ID INT, [With Blank] VARCHAR(100));
INSERT INTO #tbl2 VALUES
(1,'Value 1')
,(2,'Value 2');
SELECT dbo.CreateHTMLTable
(
(
SELECT ID
,'The new name' AS [SomeOtherName/#caption] --set a caption
,[With Blank] AS [SomeOtherName]
FROM #tbl2 FOR XML PATH('row'),ELEMENTS XSINIL
)
,NULL,NULL,NULL
);
<table>
<thead>
<tr>
<th>ID</th>
<th>The new name</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Value 1</td>
</tr>
<tr>
<td>2</td>
<td>Value 2</td>
</tr>
</tbody>
</table>
Full CSS-support and hyper-links
You can use attributes to pass over a link or a row-based and even a value-based class to mark columns and even cells for CSS styling.
--a mock-up table with a row based condition and hyper-links
DECLARE #tbl3 TABLE(ID INT, [With blank] VARCHAR(100),Link VARCHAR(MAX),ShouldNotBeNull INT);
INSERT INTO #tbl3 VALUES
(1,'NoWarning',NULL,1)
,(2,'No Warning too','http://www.Link2.com',2)
,(3,'Warning','http://www.Link3.com',3)
,(4,NULL,NULL,NULL)
,(5,'Warning',NULL,5)
,(6,'One more warning','http://www.Link6.com',6);
--The query adds an attribute Link to an element (NULL if not defined)
SELECT dbo.CreateHTMLTable
(
(
SELECT
CASE WHEN LEFT([With blank],2) != 'No' THEN 'warning' ELSE NULL END AS [#class] --The first #class is the <tr>-class
,ID
,'center' AS [Dummy/#class] --a class within TestText (appeary always)
,Link AS [Dummy/#link] --a mark to pop up as link
,'New caption' AS [Dummy/#caption] --a different caption
,[With blank] AS [Dummy] --blanks in the column's name must be tricked away...
,CASE WHEN ShouldNotBeNull IS NULL THEN 'MarkRed' END AS [ShouldNotBeNull/#class] --a class within ShouldNotBeNull (appears only if needed)
,'Should not be null' AS [ShouldNotBeNull/#caption] --a caption for a CamelCase-ColumnName
,ShouldNotBeNull
FROM #tbl3 FOR XML PATH('row'),ELEMENTS XSINIL),'testTbl','testTh','testTb'

As a possible enhancement one might pass in a one-row-footer with aggregated values as additional parameter and append it as <tfoot>
All these answers work fine but I ran into a problem recently where I wanted to have conditional formatting on the html ie. I wanted the style property of the td to vary based on data. The basic format is similar with the addition of setting td = :
declare #body nvarchar(max)
set #body =
cast
(select
'color:red' as 'td/#style', td = p.ProblemType, '',
td = p.Onset, '',
td = p.DiagnosisStatus, ''
from tblProblemList p
where p.PatientUnitNumber = #PatientUnitNumber
for xml path('tr'), type)
as nvarchar(max)
To add in conditional formatting to this you simply need to add a case statement:
declare #body nvarchar(max)
set #body =
cast
select
cast (case
when p.ProblemType = 1 then 'color:#ff0000;'
else 'color:#000;'
end as nvarchar(30)) as 'td/#style',
td = p.ProblemType, '',
td = p.Onset, '',
td = p.DiagnosisStatus, ''
from tblProblemList p
where p.PatientUnitNumber = #PatientUnitNumber
for xml path('tr'), type)
as nvarchar(max)
I ran into this problem awhile ago. Here is how I solved it:
SELECT
p.ProblemType AS "td"
, '' AS "text()"
, p.Onset AS "td"
, '' AS "text()"
, p.DiagnosisStatus AS "td"
FROM tblProblemList p
WHERE p.PatientUnitNumber = #PatientUnitNumber
FOR XML PATH('tr')
Try this:
FOR XML raw, elements, root('tr')
There are a tremendous answers already. I just wanted to add that you can also use styles within your query which might be a good in terms of design.
BEGIN
SET NOCOUNT ON;
DECLARE #htmlOpenTable VARCHAR(200) =
'<table style="border-collapse: collapse; border: 1px solid #2c3e50; background-color: #f9fbfc;">'
DECLARE #htmlCloseTable VARCHAR(200) =
'</table>'
DECLARE #htmlTdTr VARCHAR(max) = (
SELECT
'border-top: 1px solid #2c3e50' as [td/#style], someColumn as td, '',
'border-top: 1px solid #2c3e50' as [td/#style], someColumn as td, ''
FROM someTable
WHERE someCondition
FOR XML PATH('tr')
)
SELECT #htmlOpenTable + #htmlTdTr + #htmlCloseTable
END
Where someColumn is your attribute from your table
And someTable is your table name
And someCondition is optional if you are using WHERE claus
Please note that the query is only selecting two attributes, you can add as many as you want and also you can change on the styles.
Of course you can use styles in other ways. In fact, it is always better to use external CSS, but it is a good practice to know how to put inline styles because you might need them
i prefer do this:
select
convert(xml,
(
select 'column1' as th,
'column2' as th
for xml raw('tr'),elements
)),
convert(xml,
(
select t1.column1 as td,
t1.column2 as td
from #t t1
for xml raw('tr'),elements
))
for xml raw('table'),elements
