Executing a stored procedure while in a cursor loop

I created a cursor to store script so that I could loop through all of the databases and list all of their tables. The looping script creation worked but I hit the 8,000 character limit barrier in SqlServer.

So rather than accumulate the entire script, I decided to execute a portion of the script while it was being generated. It did not work

Yet when I copy and paste the generated script and run it in a query panel, it works like a charm.

Attached is the code

CREATE TABLE #TableStructures(
	  [ApplicationCode] [varchar](50) NULL,
	  [RootFile] [varchar](255) NULL,
	  [DestinationTable] [varchar](255) NULL,
	  [Column Name] [varchar](128) NULL    
    )
    
    DECLARE @DBName VARCHAR(50)
    DECLARE @STRSQL VARCHAR(8000) 
    SET @strSQL =''
    DECLARE curDBName CURSOR  FOR SELECT name FROM sys.databases WHERE name NOT IN('CommonPrograms','ExtractorControl','master','model','msdb','tempdb')

    OPEN curDBName
    FETCH NEXT FROM curDBName INTO @DBName
    WHILE @@FETCH_STATUS=0
      BEGIN
	      SET @strSQL = @strSQL + 
        'INSERT INTO #TableStructures (ApplicationCode, RootFile, DestinationTable, [Column Name])
         SELECT ExtractorControl..FilesToProcess.ApplicationCode, ExtractorControl..FilesToProcess.RootFile, ExtractorControl..FilesToProcess.DestinationTable, '+ @DBName +'..syscolumns.name AS ''Column Name'' 
         FROM (ExtractorControl..FilesToProcess INNER JOIN '+ @DBName +'..sysobjects ON ExtractorControl..FilesToProcess.DestinationTable = '+ @DBName +'..sysobjects.name) INNER JOIN '+ @DBName +'..syscolumns ON '+ @DBName +'..sysobjects.id = '+ @DBName +'..syscolumns.id
         GROUP BY ExtractorControl..FilesToProcess.ApplicationCode, ExtractorControl..FilesToProcess.RootFile, ExtractorControl..FilesToProcess.DestinationTable, '+ @DBName +'..syscolumns.name, '+ @DBName +'..sysobjects.xtype
         HAVING ('+ @DBName +'..sysobjects.xtype)= ''U''' + CHAR(10)
        EXEC @STRSQL  
        PRINT @STRSQL    
        SET @strSQL =''    
        FETCH curDBName INTO @DBName
      END

    CLOSE curDBName
    DEALLOCATE curDBName   
    
    SELECT * FROM #TableStructures
