sql server - Show row from block of string without cursors or while loops -

i have variable containig numerous of lines string looking that:

senteqweqence text sentence -1 text sendasdadadastence other text

my goal extract first line variable cointaining string -1 regardless of text above or below line, without using cursors or while loops.

expected result: sentence -1 text

what have tried far:

declare      @sql nvarchar(max),     @end int,     @start int  set @sql =  'senteqweqence text sentence -1 text sendasdadadastence other text'  set @end = charindex(char(10),@sql,charindex('-1',@sql))  set @start = charindex(char(10),reverse(@sql),1)  print substring(@sql,@start,@end-@start) 

something should going. might need add or subtract character @ either end of substring:

set @end = charindex(char(10),@sql,charindex('-1',@sql))   set @start = @end - charindex(char(10),reverse(left(@sql,@end)),charindex('1-',reverse(left(@sql,@end))))+2 print substring(@sql,@start,@end-@start)
