dbcc on one or several databases
Posted on 2012-12-27
Hello,
How can I modify this script for executing dbcc on one or several databases?
{
if ($verbose) {$VerbosePreference = "Continue"}
if ($debug) {$DebugPreference = "Continue"}
dbcc_checkdb $I $D
}
function dbcc_checkdb ($I, $D)
{
$cn = new-object system.data.SqlClient.SqlC
"Data Source=$I;Integrated Security=SSPI;Initial Catalog=$D");
$ds = new-object System.Data.DataSet "dsCheckDB"
$query = "DBCC CHECKDB($D) WITH TABLERESULTS"
$da = new-object "System.Data.SqlClient.Sql
$da.Fill($ds)
$dtCheckDB = new-object "System.Data.DataTable" "dsCheckDB"
$dtCheckDB = $ds.Tables[0]
$dtCheckDB | Format-Table -autosize `
-property Error, Level, State, MessageText, `
RepairLevel, Status, DbId, ObjectId, `
IndexId, PartitionId, AllocUnitId, File, `
Page, Slot, RefFile, RefPage, RefSlot, Allocation
}
Thanks

If you run following logic on master database, it would run dbcc checkdb for all the databases
declare @table table (SNO int identity(1,1), [name] sysname)
declare @i int, @cnt int, @dbname sysname, @query nvarchar(100)
insert into @table ([name])
select [name] from sys.sysdatabases
set @i = 1
while @i <= @cnt
begin
select @dbname = [name] from @table where SNO = @i
set @query = ';
DBCC CHECKDB;'
set @query = 'use ' + CAST(@dbname as varchar(30)) + ' ' + @query
print @query
exec sp_executesql @query
set @i = @i + 1
end
declare @table table (SNO int identity(1,1), [name] sysname)
declare @i int, @cnt int, @dbname sysname, @query nvarchar(100)
insert into @table ([name])
select [name] from sys.sysdatabases
set @i = 1
while @i <= @cnt
begin
select @dbname = [name] from @table where SNO = @i
set @query = ';
DBCC CHECKDB;'
set @query = 'use ' + CAST(@dbname as varchar(30)) + ' ' + @query
print @query
exec sp_executesql @query
set @i = @i + 1
end

Well, the script appears to be OK with a single database - right ?
So, the question is how to make it loop around for multiple $D given the instance of $I
Ideally, create a procedure on your SQL Server and simply pass the $D as a parameter to the stored procedure and the parameter can have multiple database names seperated by a delimiter (like a comma).
Or, create an arrary of database names and then use that to loop around and build up your query. Or, if you need to process each database seperately (because of results) then you will also need to include keeping the results / processing before moving onto next.
Or, you could build up a query to go through each one and collect the results (and I have cheated a little by simply referring to column names as col1 col2 etc). Note that the #checkdb temp table MUST match the correct number of columns, so if doing a different checkdb then that table will be different....
And the above could be made into a SP on the server and pass a delimited list of DB names

if object_id('tempdb..#checkdb','U') is not null drop table #checkdb
create table #checkdb (id int identity,[error] varchar(100), [level] varchar(100), [state] varchar(100), [MessageText] varchar(555), [repairlevel] varchar(100), [status] varchar(100), col1 varchar(100), col2 varchar(100), col3 varchar(100), col4 varchar(100), col5 varchar(100), col6 varchar(100), col7 varchar(100), col8 varchar(100), col9 varchar(100), col10 varchar(100),col11 varchar(100), col12 varchar(100), col13 varchar(100), col14 varchar(100), col15 varchar(100), col16 varchar(100), col17 varchar(100))
insert #checkdb (MessageText) values ('dbcc checkdb(my_db) with tableresults')
insert #checkdb
exec ('dbcc checkdb(my_db) with tableresults')
insert #checkdb (MessageText) values ('dbcc checkdb(adventureworks2012) with tableresults')
insert #checkdb
exec ('dbcc checkdb(adventureworks2012) with tableresults')
select * from #checkdb

OK...
Then have a look at : http://cornasdf.blogspot.com.au/2012/06/powershell-to-run-dbcc-checkdb-loop-for.html
Thats doing a checkdb, with no info messages, and you want with tableresults, so, the output will be slightly different.
But the important part is it shows how to loop around (I wouldnt kill the connection each time either).
