Hi Guys,
trying to figure out how to replace random text between 2 words.
For example: this is the text that is random but two words are set
What I need is to create a SQL to replace the text between the words text and two with say a word new.
Any hints are very welcomed ! :) Thank you. |

This works on the example you provided.
declare @str varchar(100) = 'this is the text that is random but two words are set'
SELECT
STUFF(@str
,PATINDEX('%text %',@str) +5
,PATINDEX('% two%',@str)-PATINDEX('% text%',@str)-6
,'New'
)

Thank you for the example. Now this works on a given row.
Though how do you make it loop throught say a field 'fldA' in a table 'TBL_TABLE' in every row available in the table?
Thanks ! |

SELECT
STUFF(YourColumn
,PATINDEX('%text %',YourColumn) +5
,PATINDEX('% two%',YourColumn)-PATINDEX('% text%',YourColumn)-6
,'New'
)
from YourTable

This was too easy to be true :)
When I execute this I get:
Argument data type text is invalid for argument 1 of stuff function.
Done some searching and realized that it doesn like TEXT datatype, so I've casted to varchar(8000) and now it seems to just erase everything rather than just the part in between the 2 strings:
UPDATE TBL_ISSUE SET fldA = STUFF(Cast(fldA as varchar(8000)),PATINDEX('display:none',fldA) +5 ,PATINDEX('</SPAN>',fldA)-PATINDEX('display:none',fldA)-6 ,'New text inserted') WHERE ID = 1001
Any ideas why? Thank you !

If you provide some sample data then I'm sure someone will be able to help! |

Good point, here goes sample data:

</SPAN><br />some mroe text here
Basically the text between and including the red tags was injected into 100's of rows as part of some text. And I need to get rid of it, or rather only the part with the links that always starts with <span style='display:none'> and end with </span> .
The easiest way for me to get rid of this was to replace anything in between the start SPAN and end SPAN tags. The field is TEXT type in MS-SQL.
Ideas?
