If you:

1) always, or

2) almost always, or

3) most critically

search these tables using RECORD_TYPE_CD, as in this query, then you should cluster those tables first on RECORD_TYPE_CD. That...

I still say don't explicitly code it unless the code requires it (some system procs require unicode strings specifically, for example), because it can cause performance...

Agreed... and the catch here is that if this happens, what else could happen? If you use the "N" prefix for the literals whenever NVARCHAR is used,...

Thank you! Are their any other good ways to stop a sql injection?...

As a quickie "solution", for now, something like this:

SET ANSI_NULLS ON;

SET QUOTED_IDENTIFIER ON;

GO

ALTER PROCEDURE <proc_name>

@ID int,

@State varchar(30),

@ColumnName varchar(100),

@NewValue datetime

AS

SET NOCOUNT ON;

IF @State LIKE '%[;]%' OR @ColumnName LIKE '%[;]%' OR @NewValue...

Or the object(s) could be in a schema that is not the default schema, since the q is written as:

DROP TABLE table1

rather than

DROP TABLE schema_name.table1

Almost certainly not the answer the...

Sorry if this overlaps already-posted code, was busy for a long while before I was able to get back to working on this:

T.CallQueue, T.ReportQueue, T.ServiceLevel,

What's really critical here is how the 680MrowsTable is clustered. Best for what you are doing here would be ( CustomerId, ACTdatetime ). If this is typical of...

If UAN is how you do lookups and, especially, joins, then you'd probably get better overall performance by clustering the table on UAN rather than on an identity column. ...

Or:

id bigint IDENTITY(12345000000000, 1) NOT NULL,

I'd be more concerned with log waits and/or dynamic log growth than with log flushes per second. If you're writing a lot of data, you will have a lot...
