Answer 1

Declare @YourTable table (Col1 varchar(50))
Insert Into @YourTable values
('5.78'),
('14.5'),
('14.67'),
('12'),
('10.10 VERIFIED'),
('15.3%'),
('10'),
('10.0'),
('6.89'),
('TNT')

Select Col1
      ,Value = Left(col1,patindex('%[0-9] %',replace(col1,'%',' ')+' '))
 From @YourTable 
 Where cast(Left(col1,patindex('%[0-9] %',replace(col1,'%',' ')+' ')) as money)>=10

返回

Col1            Value
14.5            14.5
14.67           14.67
12              12
10.10 VERIFIED  10.10
15.3%           15.3
10              10
10.0            10.0
