I tried to run the following command:

```
UPDATE EN190 
set Sys_DisplayTitle = (SELECT EP190_1 FROM EN190 WHERE Sys_ID = 4705)
WHERE Sys_ID = 4706

```

The value of (SELECT EP190\_1 FROM EN190 WHERE Sys\_ID = 4705) is a string: 

> 
> SomeValue
> 
> 
> 

and that what I expected to be in (SELECT EP190\_1 FROM EN190 WHERE Sys\_ID = 4706)  

but the value in this field is now the following string: 

> 
> [SomeValue]
> 
> 
> 

How can I solve this?
