Like below query, is there any query which can return the execution status of a function in SQL server using sys.dm_exec_?
SELECT TOP 1
d.object_id,
d.database_id,
OBJECT_NAME(object_id,database_id) 'proc name',
d.cached_time,d.last_execution_time, d.total_elapsed_time,
(d.total_elapsed_time/d.execution_count)/1000 AS [avg_elapsed_time],
d.last_elapsed_time/1000 as last_elapsed_time,
d.execution_count,
*
FROM
sys.dm_exec_procedure_stats AS d
WHERE
OBJECT_NAME(object_id, database_id) = 'ssp_StoredProcedureName'
ORDER BY
d.Last_Execution_Time DESC
You can't get exact function execution stats in versions below SQL2016.But from SQLSERVER 2016,we have sys.dm_exec_function_stats.
Applies to: SQL Server (SQL Server 2016 Community Technology Preview
3.2 (CTP 3.2) through current version), Azure SQL Database, Azure SQL Data Warehouse Public Preview.

I set up a connection to a Hive server using the Hortonworks ODBC Driver for Apache Hive. Version info is below:
OS: Windows Server 2012 R2 Standard
Hive: 1.2.1000.2.6.5.4-1
Hadoop: 2.7.3.2.6.5.4-1

I can run the queries below using the connector that I configured in Teradata SQL Assistant with no issues. I set up my DSN as a linked server in SSMS. However, when I attempt to run the queries in SSMS using openquery, I have some issues. Info on my SQL Server is below:
Microsoft SQL Server 2016 (SP2-CU3) (KB4458871) - 13.0.5216.0 (X64) Sep 13 2018 22:16:01 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows Server 2012 R2 Standard 6.3 <X64> (Build 9600: ) (Hypervisor)
Here is some info on the table that I am querying:
Table Name: instrumentapps_event
Using OPENQUERY, I am capable of querying the Hive DB through SSMS with the following query:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event')
The above query returns the contents of the desired table. However, the query below produces an error:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event WHERE to_date(from_unixtime(UNIX_TIMESTAMP(load_ts,''yyyy/MM/dd''))) >= to_date(''2019-03-01'')')
The error is as follows:
Msg 7355, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "KMhivehttp" supplied inconsistent metadata for a column. The name was changed at execution time.
How can I fix this?
While I'm unsure how to fix the problem that I previously faced (I suspect it to be a bug with the Hortonworks ODBC driver), I did discover a workaround.
Instead of running:
SELECT * FROM OPENQUERY(KMhivehttp,
'SELECT *
FROM dmfwk_gold.instrumentapps_event
WHERE to_date(from_unixtime(UNIX_TIMESTAMP(load_ts,''yyyy/MM/dd''))) >=
to_date(''2019-03-01'')
')
I now use:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event')
WHERE load_ts >= CAST('2019-03-01' AS DATE);
This allows me to avoid any metadata errors.
when i connected to the hdp3.1 use other jdbc,I can't use the custom sql with this error:
An error occurred while communicating with the data source.
Bad Connection: Tableau could not connect to the data source.
com.tableausoftware.jdbc.TableauJDBCException: Error reading metadata for prepared query: SELECT *
FROM (
select boxid,boxserialno from "dw"."dim_boxinfo" limit 10
) Custom_SQL_Query
LIMIT 1
Method not supported
There was a Java error.
I have been experimenting using the code below and it seems it does not work.
DBCC TRACEON (460);
DECLARE #aa as TABLE (name varchar(5))
INSERT INTO #aa
SELECT '1234567890'
Error
String or binary data would be truncated
Expected error:
String or binary data would be truncated in table #aa, column name. Truncated value: '1234567890'
According to https://www.procuresql.com/blog/2018/09/26/string-or-binary-data-get-truncated/ SQL Sever 2019 will be able to identify the columns that have been truncated, but can be used in SQL Server 2016 using TRACEON 460.
In terms of roles, I have "public", "processadmin", and "sysadmin".
In the sys.messages I think the patch for this feature based on message_id=2628:
+------------+------------------------------------------------------------------------------------------------------+
| message_id | text |
+------------+------------------------------------------------------------------------------------------------------+
| 2628 | String or binary data would be truncated in table '%.*ls', column '%.*ls'. Truncated value: '%.*ls'. |
| 8152 | String or binary data would be truncated. |

The new error message hasn't yet been back-ported to SQL Server 2016. From this post (emphasis mine):
This new message is also backported ... (and in an upcoming SQL Server 2016 SP2 CU) ...
This CU has not been delivered yet. The most recent, CU5 (13.0.5264.1), was released in January and did not include it.
And just a small correction, you need to opt in to this behavior (via the trace flag) even in the SQL Server 2019 CTPs. The reason is that a different error number is produced, and this could break existing applications and unit tests that behave based on the error number raised. This will be documented as a breaking change when SQL Server 2019 is released, but I'm sure it will still bite some people when they upgrade.
Currently I'm trying to query the Windows Search Service from a SQL Server 2008 R2 instance (also tested on SQL Server 2012) . Windows Search is being exposed as an OLE DB datasource, giving me several options to query the search index. When configuring a new Linked Server in SQL Server, Management Studio gives me the option to select the Microsoft OLE DB Provider for Search, implying that I should be able to connect to it from SQL Server. It turns out to be a challenge to get this up and running however. Below you'll find the error message I stumbled upon.
OLE DB provider "Search.CollatorDSO" for linked server "TESTSERVER" returned message "Command was not prepared.".
Msg 7399, Level 16, State 1, Line 2
The OLE DB provider "Search.CollatorDSO" for linked server "TESTSERVER" reported an error. Command was not prepared.
Msg 7350, Level 16, State 2, Line 2
Cannot get the column information from OLE DB provider "Search.CollatorDSO" for linked server "TESTSERVER".
Things get even more interesting. Although the Linked Server solution isn't working, I'm able to wrap code that queries Windows Search in a CLR Function (using MSDN: Querying the Index Programmatically) and use if successfully within SQL Server. This is however less desirable, because of the steps needed to set it up (deploying the library, configuring permissions, etc.). I've tried several parameter settings, without any luck. I've also tried enabling some of the Search.CollatorDSO provider options, like allowing the provider to be instantiated as an in-process server. I'm currently using the settings below. For security I'm using the login's current security context.
Provider: Microsoft OLE DB Provider for Search
Data source: (local)
Provider string: Provider=Search.CollatorDSO.1;EXTENDED?PROPERTIES="Application=Windows"
Location: -
Additionally I need to search network drives, can this be done using shared Windows libraries?
I'm aware more people have been struggling with this problem over the last few years. I'm wondering if someone has been able to get this up and running, or could point me in the right direction.
OLEDB Works
Normal ADO/OLEDB components can query the Windows Search service with the connection string:
provider=Search.CollatorDSO.1;EXTENDED PROPERTIES="Application=Windows"
And an example query:
SELECT TOP 100000 "System.ItemName",
"System.ItemNameDisplay",
"System.ItemType",
"System.ItemTypeText",
"System.Search.EntryID",
"System.Search.GatherTime",
"System.Search.HitCount",
"System.Search.Store",
"System.ItemUrl",
"System.Filename",
"System.FileExtension",
"System.ItemFolderPathDisplay",
"System.ItemPathDisplay",
"System.DateModified",
"System.ContentType",
"System.ApplicationName",
"System.KindText",
"System.ParsingName",
"System.SFGAOFlags",
"System.Size",
"System.ThumbnailCacheId"
FROM "SystemIndex"
WHERE CONTAINS(*,'"Contoso*"',1033)
You can try the query directly on SQL Server in SQL Server Management Studio by attempting to run:
SELECT *
FROM OPENROWSET(
'Search.CollatorDSO',
'Application=Windows',
'SELECT TOP 100 "System.ItemName", "System.FileName" FROM SystemIndex');
Which gives the errors:
OLE DB provider "Search.CollatorDSO" for linked server "(null)" returned message "Command was not prepared.".
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "Search.CollatorDSO" for linked server "(null)" reported an error. Command was not prepared.
Msg 7350, Level 16, State 2, Line 1
Cannot get the column information from OLE DB provider "Search.CollatorDSO" for linked server "(null)".
