Lets say I have this table
------- --------------------------------------------------------------------------
| id | json_text |
------- --------------------------------------------------------------------------
| aWoJl | {"color":"#1B3451","help_text":"color is here but dont replace me"} |
------- --------------------------------------------------------------------------
| r5Njc | {"color":"#1B3451","help_text":"color is also here but dont replace me"} |
------- --------------------------------------------------------------------------
Now I want to change color value from #1B3451
to #1e72d2
. How can I do that?
I have tried using replace()
, but no result as of now and when trying to use wildcards, it is throwing error.
Here is the SQL fiddle . http://sqlfiddle.com/#!18/6db3f9/1
CodePudding user response:
You have to convert first to VARCHAR or NVARCHAR then REPLACE
UPDATE temptable set [json_text] = REPLACE(CAST([json_text] AS NVARCHAR(MAX)),N'#1B3451',N'#1e72d2');
