Dynamic SQL concatenate strings

Question

Please see the SQL below:

declare @TableName VarChar(100)
declare @field1 varchar(100)
declare @field2 varchar(100)
set @TableName = 'Person.Person'
set @field1  = 'LastName'
set @field2  = 'FirstName'
Declare @SQL VarChar(1000) SELECT @SQL = 'SELECT ' + @field1 + ',' + @field2 + ' FROM '
 SELECT @SQL = @SQL + @TableName 
 Exec ( @SQL) 

The result set appears in two columns ie firstname and surname. Is it possible to concatenate the columns so the output appears like this?

I have found a quote on this website: http://technet.microsoft.com/en-us/library/ms188001.aspx , which states: "concatenating two strings with the + operator, are not allowed". Therefore I suspect it is not possible. Is there a workaround.

Answer 1

declare @TableName VarChar(100)
declare @field1 varchar(100)
declare @field2 varchar(100)
set @TableName = 'dbo.Person'
set @field1  = 'LastName'
set @field2  = 'FirstName'
Declare @SQL VarChar(1000) SELECT @SQL = 'SELECT ' + @field1 + '+'',''+' + @field2 + ' FROM '
 SELECT @SQL = @SQL + @TableName 
 print @sql
 Exec ( @SQL)
