Answer 1

What about this:

Short explanation: Replacing . with xml-tags will "split" this string in as many "parts" as there are in your string. The XML-value method will take the first item's value which is the string up to the first .

Declare @Temp Table(Data VarChar(1000))

Insert Into @Temp Values('Lalallaa GOAL: This is the truthmeow. Meow.  ')
Insert Into @Temp Values('Lalallaa GOAL: This is the truth. Meowrwr. ')
Insert Into @Temp Values('lALALLA GOAL: This is the truth. Meowrwr. NOTINCLUDED: WAWAW')


Select CAST('<x>' + REPLACE(SubString(Data,PATINDEX ('%GOAL%',Data), 8000),'. ','</x><x>') + '</x>' AS XML).value('x[1]','varchar(max)')
From   @Temp
