Generate insert statements with column names for any or all tables

,

Call the stored procedure to generate insert statement for any given table.  Or generate inserts for all tables using something like:

exec sp_MSforeachtable @command1="exec [spd_Build_Insert_Into_Stmt_With_Identity] '?','?','[LINKEDSERVERNAME].DATABASENAME.'"

--Example: For every table in the current database, generate a truncate/insert
exec sp_MSforeachtable @command1="exec [spd_Build_Insert_Into_Stmt_With_Identity] '?','?','[LINKEDSERVERNAME].DATABASENAME.'"
