Hi Gurus,

I'm using SQL Server 2008 R2. I've gotten below SQL script from Internet which is used to monitor SQL log shipping, see below:

DROP Table #log_shipping_monitor

DROP TABLE #secondary_monitor
------------------------------

I've run this script on my secondary database and it works OK.

However, when I tried to run in on a another separated system which has a seconday database, it's giving some errors as shown below:
Msg 245, Level 16, State 1, Line 127Conversion failed when converting the nvarchar value 'DBCLUSTER' to data type bit.

Appreciate if you could help to fix the error.

Thank you.

It looks like your problem is as shown below in red. Your temp table has the "is_primary" column defined as a bit but you are attempting to set it to the "@primary_server" value which is defined as sysname.

--
-- we have a primary entry
--
insert into #log_shipping_monitor (
status
,is_primary
,server
,database_name
,is_backup_alert_enabled)
values (
1
,@primary_server
,@primary_database
,@backup_threshold
,@is_backup_alert_enabled)

Hi mandm,

Thank you for your reply and help.

Yes, I think you've spotted the problem.

The question is, how should it be fixed?

Appreciate for your help.

Well there are a lot of ways to fix it but without analyzing the whole script probably the quickest and safest would be as follows.

1) Declare new variable @is_primary bit
2) Before the insert statement set the new variable
 
SELECT @is_primary = CASE WHEN @primary_server IS NULL
THEN 0
ELSE 1
END

3) Replace the @primary_server in the values with the new @is_primary variable.

Hi mandm,

Thank you for your reply and help.

I've tried to follow you suggestion, but ended up with some errors.

I don't have much experiences in dealing with SQL queries.

Could you help to amend to codes that I've posted earlier?

Thanks so much.

Hi mandm,

Thank you for your reply and help.

Had tested and it's working OK. No errors anymore. Great work ... so happy :) Thanks so much.

However, when I checked my inbox, it's sending an empty email. It should have some information something like below.

Database:PET
Status:Good
Last Copied File:H:\BAK\PET_20150121020001.trn
Time since last Copy (min):12
Last Restored File:H:\BAK\PET_20150120230001.trn
Time since last Restore (min):12
Restore Latency (min):180
Restore Threshold (min):180

Appreciate for your help.

Thanks.

I'm glad the fix took care of the error.

Is the email empty from both servers or just the one? I'm assuming the empty email is something new right?

Hi mandm,

Thank you for your reply and help.

I've checked again and confirmed the issue is only coming from the "2nd" secondary server, the one with the data type error mentioned earlier. Email is sent and received, but empty.

I've used the same script modified as per your update and it's working OK on the other secondary db (the "1st" secondary db). Email is sent and received, but it's not empty.

Could you help?

Thanks.

Hi mandm,

For your info, here are the errors after execution.

Msg 110, Level 15, State 1, Line 142
There are fewer columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must

match the number of columns specified in the INSERT statement.

Thanks.

Can you post the current script now that we've made changes? That will make the line references match up to what you're seeing.

Hi mandm,

Thanks for your reply.

I've posted our entire script that I've tested, no more erros, but it does not produce any content when it's sent out.

Please ignore below error message which I've posted earlier.
Msg 110, Level 15, State 1, Line 142

I was experimenting with some codes and realized it's not related to our changes.

Hope you can help.

Thanks.


- Peter

Do a select out of the #log_shipping_monitor right before the email section (starting at or around line 518) as shown below in red. My guess is that one or more of the values used in the email body (@Body variable) are NULL in the temp table. Please post back the results of the SELECT.

Hi mandm,

Thanks for your reply.

I've tried below query, but it returned with some errors:
SELECT * FROM #log_shipping_monitor

Errors:
Msg 208, Level 16, State 0, Line 1
Invalid object name '#log_shipping_monitor'.

I've tried to comment out the last 3 lines of "DROP" commands, but it still does not work.

How to extract the result in a proper method?

Thanks.

And you put the command before the email section like I posted? If it's in the the right spot and spelled right the next code section does the same command with a TOP 1 so it should be a valid object.

Hi mandm,

Thanks for your reply.

Yep, got it now. The output is quite long, thus I've typed them manually below and break them into sections.

idx status is_primary server database_name
1 0 0 PET-Database PET

is_backup_alert_enabled time_since_last_copy last_copied_file
NULL 6 D:\bak\PET_20150122053000.trn

time_since_last_restore last_restored_file last_restored_latency
6 D:\bak\PET_20150122023000.trn 180

last_restored_latency restore_threshold
180 180

is_restore_alert_enabled ts
1 0x00000000000007F8

I've arranged them nicely in notepad, but it behaves differently when pasted here and preview.

Anyway, hope they can be used.

Was this run on the server that sends the blank email? In looking at your results it looks like it wasn't because your is_primary = 0 but the code we added should have made it 1.



idx status is_primary server database_name
1 0 0 PET-Database PET



If this was run on the server with the issue then we need to look at the @Body variable before the email is sent by selecting that as shown below in red.

SET @Body = RTRIM(@Body) + '</table>'

SELECT @Body

EXECUTE msdb.dbo.sp_send_dbmail @recipients = @Recipients
,@subject = @Subject
,@body = @Body
,@body_format = 'HTML'


The trick for maintaining formatting when you paste code or results is to add the keywords code before it and /code after it and wrap each of them in square brackets (i.e. [keyword] and [/keyword]).
