Refresh All Views on SQL Server

Whenever you make a change to a table - say, to modify a column - you need to update all the views that depend on that column.  This script will find and update all your views. 




-- Back Up All Databases
-- by Bryan Valencia

--create temp table
declare @temp table(commands varchar(500), completed bit)

--load it with backup commands
insert into @temp (commands, completed)
(
    SELECT DISTINCT 'EXEC sp_refreshview ''' + name + '''',0
    FROM sys.objects AS so
    INNER JOIN sys.sql_expression_dependencies AS sed
        ON so.object_id = sed.referencing_id
    WHERE so.type = 'V'
    and is_schema_bound_reference = 0
)

--variable for the current command
declare @thisCommand varchar(500);

--loop through the table
while (select count(1) from @temp where completed=0)>0
begin
    --find the first row that has not already been executed
    select top 1 @thisCommand = commands from @temp where completed=0

    --show the command in the "mesage" output window.
    print @thisCommand

    --execute the command
    EXEC (@thisCommand);

    --flag this row as completed.
    update @temp set completed=1 where commands=@thisCommand
end

--show the user the rows that have been found.
select * from @temp




Of course if a view is now no longer correct, you'll see on your messages tab in SQL Server Management Studio.
