Extract string from a text after a keyword in sql?

Question

I have the necessity to extract content from a text in a SQL field after a keyword. For example if i have a field called description in a table, and the table content for that field is:

Description

asdasf keyword dog

aeee keyword cat

ffffaa keyword wolf

I want to extract and save the text after "keyword " (in this case dog,cat and wolf) and save it in a view or simply show it with a select. Thank you.

Answer 1

Here is an example using SUBSTRING():

SELECT SUBSTRING(YourField, CHARINDEX(Keyword,YourField) + LEN(Keyword), LEN(YourField))

Another example:

declare @YourField varchar(200) = 'Mary had a little lamb'
declare @Keyword varchar(200) = 'had'
select SUBSTRING(@YourField,charindex(@Keyword,@YourField) + LEN(@Keyword), LEN(@YourField) )

Result:

 a little lamb

Please note that there is a space before the 'a' in this string.
