I am new to this. I am trying to change the column ID from float to varchar but get error message here. "The type name 'Programmer.dbo.'Diabetic Patient 12 years ove$'' contains more than the maximum number of prefixes. The maximum is 1.
" what is not correct here? 

SELECT \*
 FROM [Programmer].[dbo].['Diabetic Patient 12 years ove$']

```
  select convert ([Programmer].[dbo].['Diabetic Patient 12 years   ove$'].id as varchar(200))

```
