EDIT: create a column list to avoid binary columns...

columns, which are not directly convertible into XML RAW are added with "invalid data":

DECLARE @Commands TABLE(ID INT IDENTITY,cmd NVARCHAR(MAX));

INSERT INTO @Commands(cmd)
SELECT '(SELECT TOP 3 ' 
                        + STUFF(
                            (
                                SELECT ',' + QUOTENAME(COLUMN_NAME)
                                FROM INFORMATION_SCHEMA.COLUMNS AS c 
                                WHERE c.TABLE_CATALOG=t.TABLE_CATALOG AND c.TABLE_SCHEMA=t.TABLE_SCHEMA AND c.TABLE_NAME=t.TABLE_NAME
                                  AND c.DATA_TYPE NOT IN('image','text') AND c.DATA_TYPE NOT LIKE '%BINARY%'
                                FOR XML PATH('')
                            ),1,1,''
                          )
                        + 
                            (
                                SELECT ',''invalid data'' AS ' + QUOTENAME(COLUMN_NAME)
                                FROM INFORMATION_SCHEMA.COLUMNS AS c 
                                WHERE c.TABLE_CATALOG=t.TABLE_CATALOG AND c.TABLE_SCHEMA=t.TABLE_SCHEMA AND c.TABLE_NAME=t.TABLE_NAME
                                  AND (c.DATA_TYPE IN('image','text') OR c.DATA_TYPE LIKE '%BINARY%')
                                FOR XML PATH('')
                            )

                        + ' FROM '  + QUOTENAME(t.TABLE_CATALOG) + '.' + QUOTENAME(t.TABLE_SCHEMA) + '.'
       + QUOTENAME(t.TABLE_NAME) + ' FOR XML RAW,TYPE) AS ' + QUOTENAME(t.TABLE_CATALOG + '_' + t.TABLE_SCHEMA + '_' + t.TABLE_NAME)  
FROM INFORMATION_SCHEMA.TABLES AS t WHERE t.TABLE_TYPE='BASE TABLE';

DECLARE @finalCommand NVARCHAR(MAX)=
