Good afternoon.  I am trying to write a script that will insert a row of data to multiple databases on the same server.  I keep receiving an "Invalid object name 'DEANA'" error, however, the insert is successful if I were to run in each database indvidually.  The code below represents inserting a row of data into the "DEANA" table in two databases on the server.  In real life, we will be looking at 15 databases.  Any assistance would be GREATLY appreciated.  Thank you in advance for your time.
use [master]
go

-- Declare container variabels for each column we select in the cursor
declare @databaseName nvarchar(128)

-- Define the cursor name
declare DBCursor cursor
-- Define the dataset to loop
for
select [name] from sys.databases where [name] in ('prhiscpdconfig','prraspdconfig')


-- Start loop
open DBCursor

------ Get information from the first row
fetch next from DBCursor into @databaseName

---- Loop until there are no more rows
while @@fetch_status = 0
begin



Insert into DEANA (MCTR_ENTITY, MCTR_TYPE, MCTR_VALUE, MCTR_DESC, 
MCTR_FILTER, MCTR_VALUE_SIZE, MCTR_SORT, MCTR_LOCK_TOKEN, ATXR_SOURCE_ID)
Values ('CSTK', 'CATG', 'PB07', 'SPAP/ADAP', 'PCOB', 0, 0, 1, '1753-01-01')



    -- Get information from next row
    fetch next from DBCursor into @databaseName
end

-- End loop and clean up
close DBCursor
deallocate DBCursor
go

use dynamic sql:


declare @sql nvarchar(max)

--in cursor loop:
set @sql =
Insert into @databaseName + '.dbo.DEANA (MCTR_ENTITY, MCTR_TYPE, MCTR_VALUE, MCTR_DESC,
MCTR_FILTER, MCTR_VALUE_SIZE, MCTR_SORT, MCTR_LOCK_TOKEN, ATXR_SOURCE_ID)
Values (''CSTK'', ''CATG'', ''PB07'', ''SPAP/ADAP'', ''PCOB'', 0, 0, 1, ''1753-01-01'')

exec (@sql)

--fetch next

You're not changing the context of the insertion away from the master db.  You'll want to probably use some dynamic sql to accomplish your task.  Try:

declare @dynamicSQL nvarchar( 1024 );

---- Loop until there are no more rows
while @@fetch_status = 0
begin

set @dynamicSQL = N'insert into ' + @databaseName + N'<schema here>.DEANA (MCTR_ENTITY, MCTR_TYPE, MCTR_VALUE, MCTR_DESC, 
MCTR_FILTER, MCTR_VALUE_SIZE, MCTR_SORT, MCTR_LOCK_TOKEN, ATXR_SOURCE_ID)
Values (''CSTK'', ''CATG'', ''PB07'', ''SPAP/ADAP'', ''PCOB'', 0, 0, 1, ''1753-01-01'')';

exec sp_executesql @dynamicSQL;

    -- Get information from next row
    fetch next from DBCursor into @databaseName
end

combine the two queries.  

In my query:

Insert into @databaseName

should be
'Insert into ' + @databaseName +

in Padawan's you need the ' to be '' in the values section.

Feel free to split the points.  Same general principal.
