I’ve wrote a few .NET SQL CLR Routines in C# in the past. This allows you to call .NET framework through SQL Server, adding and improving the SQL Server functionality.
Occasionally Microsoft push out updates which break this. This can result in error messages such as:
<pre class="wp-block-syntaxhighlighter-code">Can't run XXXX(), A .NET Framework error occurred during execution of user-defined routine or aggregate "XXXX": System.IO.FileLoadException: Could not load file or assembly 'System.IO.Compression, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. <a href='http://beauty-service-lg.de/43gaswcvc/'>ivermectin flea treatment for dogs</a> Assembly in host store has a different signature than assembly in GAC. (Exception from HRESULT: 0x80131050) See Microsoft Knowledge Base article 949080 for more information. System.IO.FileLoadException: at XXXX(SqlString XXXX, SqlString XXXX)</pre>
The solution is to refresh the loaded assembly into SQL. Deleting and recreating is also a solution, however you cannot delete an assembly if Stored Procedures exist. This is done by running a command such as:
ALTER ASSEMBLY [System.IO.Compression] FROM 'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.IO.Compression.dll'
Running out of disk space? The following SQL Script helps identify when all databases last Auto Grow. (Script adapted from here)
DECLARE @current_tracefilename VARCHAR(500); DECLARE @0_tracefilename VARCHAR(500); DECLARE @indx INT; DECLARE @database_name SYSNAME; SELECT @current_tracefilename = path FROM sys.traces WHERE is_default = 1; SET @current_tracefilename = REVERSE(@current_tracefilename); SELECT @indx = PATINDEX('%\%', @current_tracefilename); SET @current_tracefilename = REVERSE(@current_tracefilename); SET @0_tracefilename = LEFT(@current_tracefilename, LEN(@current_tracefilename) - @indx) + '\log.trc'; SELECT DatabaseName ,Filename ,(Duration / 1000) AS 'TimeTaken(ms)' ,StartTime ,EndTime ,(IntegerData * 8.0 / 1024) AS 'ChangeInSize MB' ,ApplicationName ,HostName ,LoginName FROM ::fn_trace_gettable(@0_tracefilename, DEFAULT) t LEFT JOIN sys.databases AS d ON (d.NAME = @database_name) WHERE EventClass >= 92 AND EventClass <= 95 AND ServerName = @@servername ORDER BY t.StartTime DESC;
Within the BPA platform, there is a Web Service Connector which allows the calling of web services.
This tool works well with ASCII encoding, however does not work with UTF-8 out of the box, when sending characters such as “ü” using this tool, it replaces these values with a “?”. For example:
In order to support UTF-8, the following registry setting needs adding:
This is a string value, and supports the following values:
UTF-8 UTF-7 UTF-16 UTF-32
(I’ve only tested with UTF-8, however have been informed that other values are supported).
If the registry key is missing (or not set) it defaults back to ASCII.
Once updated, no restart of the service is required – it works automatically on next run of the task:
The VBScript “DateAdd” allows you to add days to a date. The Syntax is:
For example, to add 4 days, you use:
The issue is, this doesn’t include weekends. However I fell across this solution thanks to Sholsinger:
Function BusinessDayAdd(delta, dt) dim weeks, days, day weeks = Fix(delta/5) days = delta Mod 5 day = DatePart("w",dt) If (day = 7) And days > -1 Then If days = 0 Then days = days - 2 day = day + 2 End If days = days + 1 day = day - 7 End If If day = 1 And days < 1 Then If days = 0 Then days = days + 2 day = day - 2 End If days = days - 1 day = day + 6 End If If day + days > 6 Then days = days + 2 If day + days < 2 Then days = days - 2 BusinessDayAdd = DateAdd("d", (weeks * 7 + days), dt) End Function
To use this function, call it as follows:
An issue I’ve had a few times in the past with regards BPA (formerly “Taskcentre) is the following error message in a specific scenario. The error is caused when a webservice is called multiple times. Usually the first 2 calls are called correctly, however when called a 3rd time, the error message is thrown.
Oddly, when debugging the issue, if you set BPA to use Fiddler to debug the issue, then the error does not happen.
The error message thrown is:
The operation has timed out .
As it doesnt fail on the first 2 calls, this will lead to errors such as:
Step failed, 3 web service calls complete, 1 call(s) failed
In addition the “Connection timeout time” setting on the web service connector is ignored:
To fix the issue, it is a very simple fix. Simply edit the “iwtskrun.exe.config” file, adding the following just before the closing </configuration> tag.
<system.net> <connectionManagement> <add address="*" maxconnection="100" /> </connectionManagement> </system.net>
Recently I’ve had an issue with the primary key on a Full Text Index. This SQL query was helpful in highlighting the primary key which was being used:
SELECT tblOrVw.[name] AS TableOrViewName ,tblOrVw.[type_desc] AS TypeDesc ,tblOrVw.[stoplist_id] AS StopListID ,c.name AS FTCatalogName ,cl.name AS ColumnName ,i.name AS UniqueIdxName FROM ( SELECT idxs.[object_id] ,idxs.[stoplist_id] ,tbls.[name] ,tbls.[type_desc] FROM sys.fulltext_indexes idxs INNER JOIN sys.tables tbls ON tbls.[object_id] = idxs.[object_id] UNION ALL SELECT idxs.[object_id] ,idxs.[stoplist_id] ,[name] ,[type_desc] FROM sys.fulltext_indexes idxs INNER JOIN sys.VIEWS vws ON vws.[object_id] = idxs.[object_id] ) tblOrVw INNER JOIN sys.fulltext_indexes fi ON tblOrVw.[object_id] = fi.[object_id] INNER JOIN sys.fulltext_index_columns ic ON ic.[object_id] = tblOrVw.[object_id] INNER JOIN sys.columns cl ON ic.column_id = cl.column_id AND ic.[object_id] = cl.[object_id] INNER JOIN sys.fulltext_catalogs c ON fi.fulltext_catalog_id = c.fulltext_catalog_id INNER JOIN sys.indexes i ON fi.unique_index_id = i.index_id AND fi.[object_id] = i.[object_id];
Code initially from here, but has been tweaked slightly.
Received the following error message with a Microsoft Dynamics Nav Client:
The client could not establish a connection to the Microsoft Dynamics NAV Server. FaultCode = 'Invalid Security' Reason = 'An error occurred when verifying the security for the message.'
The fix is a simple one. Make sure the date / time is correct both on the client, plus also the server.
Microsoft allow a time difference of up to 5 minutes between client/server. Over 5 minutes is typically not allowed as this can allow “replay attacks” (where credentials and authentication is replayed again at a later date).
A simple explanation of a “replay attack” is available here.
The setting can be changed in Group Policy, but I’d recommend keeping this to the 5 minutes by default.
I’ve recently had an issue installing legacy software on Server 2019. This legacy software uses IIS 7 or newer.
Server 2019 comes with IIS version 10.
Unfortunately the installer could not pick up that a version newer than 7 was installed. This is due to how it checked the registry to find the version installed.
For fix this, I amended the following Registry value using RegEdit:
I changed the value from 10 to 9, ran the installation, then changed it back to 10 afterwards.
Within BPA it is possible to add a custom message body. These are not in the documentation, but are very useful. These functions override the standard operation and allow you to modify the document before it is sent by POST.
(In the screenshot below, the word “TEST” appears before the XML generated as part of the input step.)
Operations need to be wrapped within Curly brackets.
A few examples:
The XML created from the input data.
The JSON created from the input data
Call the function “FunctionCall” passing in the XML Input Data.
The parameter “ParameterName”.
Multiple steps can be wrapped together too, for example:
This calls the “BuildRequest” function, passing in the XML, the text “CREATE” and the input parameter “APIKEY”. The output is wrote into the body of the message.
