Execute SQL task insert error: Column name or number of supplied values does not match table definition

Okay, this is probably a simple one for someone other than me. :) So I built this elaborate query in SSMS to construct a restore command. It works very nicely in SSMS. However, when I put it into an execute SQL task in SSIS, it errors with:

insert error: Column name or number of supplied values does not match table definition

I've stripped the query down as much as I can, to eliminate any other confusion here. Here's the stripped down version, that if you copy/paste into SSMS, and edit for one of your .bak files (name and location) you will see works nicely. However, it does not work in execute SQL query task. Again, this query serves no useful purpose as it is. I have it doing much more, to output the entire restore command, complete with file extensions, etc. that I then want to output to a variable to then later execute. (backing up on one server, restoring on another). I'm guessing that rather than doing the exec and getting the results to insert, it is attempting to insert the "exec(...) into the table, but not sure how to fix that either. I only use the below, to understand why this portion (straightforward) does not work in the SQL task.

Please help. :(

DECLARE @RestoreCommandTable table
(
    LogicalName          nvarchar(128),
    PhysicalName         nvarchar(260),
    Type                 char(1),
    FileGroupName        nvarchar(128),
    Size                 numeric(20,0),
    MaxSize              numeric(20,0),
    FileID               bigint,
    CreateLSN            numeric(25,0),
    DropLSN              numeric(25,0),
    UniqueID             uniqueidentifier,
    ReadOnlyLSN          numeric(25,0),
    ReadWriteLSN         numeric(25,0),
    BackupSizeInBytes    bigint,
    SourceBlockSize      int,
    FileGroupID          int,
    LogGroupGUID         uniqueidentifier,
    DifferentialBaseLSN  numeric(25,0),
    DifferentialBaseGUID uniqueidentifier,
    IsReadOnl            bit,
    IsPresent            bit,
    TDEThumbprint        varbinary(32)
)
INSERT INTO @RestoreCommandTable exec(N'RESTORE filelistonly FROM  DISK = N''\\myserver\SQL2005\MSSQL.4\MSSQL\backup\mydatabase.bak''')

Thanks in advance!
