Unable to install SQL Server 2022 Express (installer glitch + SSMS error)
Hi, I recently purchased a new Lenovo laptop, and I am trying to install Microsoft SQL Server 2022 Express along with SSMS. SSMS installed successfully, but SQL Server installation fails, and sometimes the installer UI glitches or does not load properly. Because of this, I am getting connection errors in SSMS like "server not found" and "error 40". I am not very familiar with technical troubleshooting. Can someone guide me step-by-step in a simple way to install SQL Server correctly? Thank you.
SSMS 22 - Not seeing the Database name information in the Status Bar and Title bar is gone.
I installed SSMS 22 yesterday and am trying to get used to the features. I am not a fan of the new layout. I might be in the future, but at the moment, not so much. Status Bar settings are all set to [True] But nothing is showing in the Status Bar. There is no Title Bar anymore. WHY Would they take away the Title Bar? That is insane. So, my question to the Forum is this. How do we get the Database Name information in the Status Bar? As stated, everything is set to TRUE in settings. Also, will the Status Bar show the title of the Editor file you are working on? (I miss the old design, to be honest. )
Synchronize SQL database between two servers
Questions (to make right the synchronize SQL database between two servers) 1. Is required to have SQL Enterprise in both servers, for to be able the synchronization? Or will be enough to have SQL Enterprise in server1. And in server2 with only SQL Express, please? 2. Which requirements are required to fulfil or prepare for to be able synchronize SQL database between two servers, please? 3. Which possibilities (when are more possible solutions) have existed for synchronize SQL database (totally awaiting between four servers), please? 4. Exist a manual for reading an synchronization of SQL server - settings and steps? Thanks in advance.
SQL Server AG Failover - Automatic Failover
Hello, I am looking for a straight and definitive answer that I was hoping someone could answer for me. I want to trust what Copilot says, but I really need to hear it from Microsoft and I can't find any documentation from Microsoft confirming my question. My Environment: 2 replicas in datacenter 1 1 replica in datacenter 2 All three (3) replicas are set to synchronous-commit mode with automatic failover. I tested the failover manually between all three (3) replicas without issue. When I test the automatic failover - I take down both replicas in datacenter 1 at the same time to simulate a datacenter outage. I look at the replica in datacenter 2 and it is just says (Resolving...) next to the replica name. The replica does not come online and the DB is not moved. When I was searching I couldn't find out why. So I turned to Copilot not solve the issue, but to see if it could point me in the right direction. I tell Copilot my setup and what happened. Copilot responded stating that by design from Microsoft you cannot have more than two (2) replicas set to synchronous-commit mode with automatic failover in a SQL Server AG instance. That if more than two (2) are set for automatic failover. The SQL Server AG will use the first two (2) replicas it sees in its metadata and ignore the rest. Copilot went into detail about why this is designed this way, but the amount of information would make this post longer than it already is. If this is true - then when I took down both replicas in datacenter 1, SQL Server AG only saw those two (2) replicas in datacenter 1 as the available replicas to use for an automatic failover and thus why the replica in datacenter 2 did not come online and the DB not being moved So let's do a test. I brought back up the two (2) replicas in datacenter 1. Then I made a change in the AG proprieties. I set the 2nd replica in datacenter 1 to manual. So 1 replica is set to automatic failover and 1 replica is set to manual failover in datacenter 1. The replica in datacenter 2 is set to automatic failover I then take down both replicas in datacenter 1 again to simulate the "outage" and the replica in datacenter 2 comes online and the DB is moved. So is Copilot right? Can there only be two (2) replicas allowed to have/use automatic failover? I cannot find a definitive answer confirming this. Or is my configuration wrong/missing something and if it is, could you please point me in the right direction on how to get this resolved?SQL Server 2005 (compatibility level 90)
Hello, I’m testing the behavior described in the SQL Server documentation for **compatibility level 90** regarding the special attributes `xsi:nil` and `xsi:type`: > “The special attributes `xsi:nil` and `xsi:type` can't be queried or modified by data manipulation language statements. This means that `/e/@xsi:nil` fails while `/e/@*` ignores the `xsi:nil` and `xsi:type` attributes. However, `/e` returns the `xsi:nil` and `xsi:type` attributes for consistency with `SELECT xmlCol`, even if `xsi:nil = "false"`. ” But on **SQL Server 2005**, I can successfully query `@xsi:nil` and it returns the expected value. I’m trying to reproduce the documented “`/e/@xsi:nil` fails” behavior, but I can’t. ### Environment - Product: **Microsoft SQL Server 2005** - Database compatibility level: **90** --- ## ✅ Repro script ```sql IF EXISTS (SELECT * FROM sys.xml_schema_collections WHERE name = 'MyTestSchema') DROP XML SCHEMA COLLECTION MyTestSchema; GO CREATE XML SCHEMA COLLECTION MyTestSchema AS N' <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="root"> <xsd:complexType> <xsd:sequence> <xsd:element name="element" nillable="true" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema>'; GO DECLARE @xmlData XML(MyTestSchema) = N' <root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <element xsi:nil="true" /> </root>'; ;WITH XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema-instance' as xsi) SELECT @xmlData.query('<result> { /root/element/@xsi:nil } </result>') AS Typed_Result; ``` ### Actual result `Typed_Result` contains `xsi:nil="true"` under `<result>...`. ### Expected result (based on docs) I expected `/root/element/@xsi:nil` to fail, or not return `xsi:nil`. --- ## Questions 1. In the documentation, does “data manipulation language statements” mean only **XML DML** (i.e., `.modify()`), not XQuery used in `SELECT` with `.query()` / `.value()`? 2. Does the “`/e/@xsi:nil` fails” behavior apply only when the XML is stored in a **table column**, not when using an **XML variable**? 3. Is the behavior different between **typed XML** (with an XML schema collection) vs **untyped XML**? 4. Can someone provide a minimal reproduction in SQL Server 2005 where `/e/@xsi:nil` fails as described? Thank you. ---Compat level 90: XML string-to-datetime UDF
Hello, I’m testing a behavior described in SQL Server documentation for **database compatibility level 90**. The docs state that a user-defined function that converts an XML constant string value to a SQL Server date/time type is marked as **deterministic**. On **SQL Server 2005**, I’m seeing the opposite: the function is marked as **non-deterministic** (`IsDeterministic = 0`). I’m trying to understand whether I’m missing a requirement/constraint or whether this is a doc mismatch / version-specific behavior. ### Environment - Product: **Microsoft SQL Server 2005** - Database compatibility level: **90** --- ## ✅ Repro script ```sql IF OBJECT_ID('dbo.fn_ParamXmlToDatetime', 'FN') IS NOT NULL DROP FUNCTION dbo.fn_ParamXmlToDatetime; GO CREATE FUNCTION dbo.fn_ParamXmlToDatetime (@xml XML) RETURNS DATETIME WITH SCHEMABINDING AS BEGIN DECLARE @y DATETIME; -- Convert an XML value to DATETIME SET @y = CONVERT(DATETIME, @xml.value('(/r)[1]', 'datetime')); RETURN @y; END GO SELECT OBJECTPROPERTY(OBJECT_ID('dbo.fn_ParamXmlToDatetime'), 'IsDeterministic') AS IsDeterministic, OBJECTPROPERTY(OBJECT_ID('dbo.fn_ParamXmlToDatetime'), 'IsPrecise') AS IsPrecise; GO ``` ### Actual result `IsDeterministic = 0` (non-deterministic) ### Expected result (based on docs) `IsDeterministic = 1` (deterministic) for this pattern under compat level 90. --- ## Questions 1. Are there additional conditions required for SQL Server to mark this UDF as deterministic (for example, specific XQuery usage, avoiding `CONVERT`, using `CAST`, using `datetime2` doesn’t exist in 2005, etc.)? 2. Does the determinism rule apply only when converting from an **XML literal constant** inside the function, rather than an XML parameter value? 3. Is this behavior different for **typed XML** (XML schema collections) vs **untyped XML**? 4. Is this a known difference/bug in SQL Server 2005 where the UDF is functionally deterministic but still reported as non-deterministic by `OBJECTPROPERTY`? Thank you for any clarification. ---Assess and upgrade to SQL Server 2025 with SSMS Migration Component

Some days ago, I worked on a support case where a customer reported application slowness affecting multiple users. Instead of jumping into traces or manually writing diagnostic queries, we used SSMS Copilot to investigate the issue. I would like to share with you how we diagnosed and understood the root cause. To illustrate the case, let’s walk through a simplified example: we create a new table, and right after that, we add a new column to it. CREATE TABLE Ejemplo2 (ID INT) BEGIN TRANSACTION ALTER TABLE dbo.eJEMPLO2 ADD NuevoCampo INT NULL Using SQL Server Management Studio and Copilot we executed the following prompt: Please, provide all currently running or suspended sessions. Include session ID, status, command, wait type (if any), application_name, wait time, and current SQL text. We got the following results: I executed multiple times the same prompt and always the session ID 67 is in suspended mode and Wait_type LCK_M_SCH_S, for this reason, I run a new prompt: Please, provide all sessions that are currently blocked by another session. Include session ID, the blocking session ID, wait type, and the blocked SQL text . At the end, I found that the session 51 is blocking the session ID 67 and for this reason, I run a new prompt: do we any have active transaction pending for commit for the session ID 51. So, I understand that the Session ID 51 has a transaction open, so, let's ask the details of the session 51, with a new prompt: Please, show the most recent SQL statement executed by session ID 51, even if the session is currently sleeping or not running any active request. Include the session status and login name as well. Use sys.dm_exec_connections and most_recent_sql_handle to retrieve the query text if necessary. Well, we identified the problem, the session ID 67 is running a SELECT * FROM sys.Ejemplo2 but it's beging blocked by the session 51. Session ID 51 hasn’t finished its transaction, and now we either need to commit, rollback, or kill that session, especially if we don’t have access to the application that owns it. Before resolving the issue, I asked Copilot an additional prompt: Please, explain why session ID 67 is currently waiting. Include the wait type, and explanation of that, the resource being waited on, how long it has been waiting (seconds), and the SQL text. Also identify if another session is blocking it. The name of the object and schema Please, provide recommendations to prevent or reduce this kind of blocking situation in the future, based on the current wait type and blocking scenario observed with session ID 67. Please, summarize all current blocking chains in the system. Include blocking session IDs, blocked session IDs, wait types, wait durations, login names, and SQL statements involved.Lesson Learned #530: Comparing Execution Plans to Expose a Hidden Performance Anti-Pattern
One of the most powerful features of SSMS Copilot is how it lets you compare execution plans and immediately show you performance issues. In this case, I would like to share with you my lesson learned comparing two queries and how they behave very differently inside the engine. We have the following queries, these are using a table _x_y_z_MS_HighCPU that contains 4 millon of rows. The column TextToSearch is a varchar(200) datatype. -- Query 1 SELECT COUNT(*) FROM [MSxyzTest].[_x_y_z_MS_HighCPU] WHERE TextToSearch = N'Value: 9'; -- Query 2 SELECT COUNT(*) FROM [MSxyzTest].[_x_y_z_MS_HighCPU] WHERE TextToSearch = 'Value: 9'; Since the query texts are different, each will have a different query ID in Query Store. By running the following T-SQL, for example, I can identify the query IDs. SELECT qsqt.query_sql_text, qsq.query_id, qsp.plan_id, qsp.query_plan_hash, qsp.last_execution_time FROM sys.query_store_query_text qsqt JOIN sys.query_store_query qsq ON qsqt.query_text_id = qsq.query_text_id JOIN sys.query_store_plan qsp ON qsq.query_id = qsp.query_id WHERE qsqt.query_sql_text LIKE '%SELECT COUNT(*)%' -- FROM [[MSxyzTest]].[[_x_y_z_MS_HighCPU]]%' ORDER BY qsp.last_execution_time DESC; Queries 1 and 2 can be compared directly. Using Copilot, I ran the following prompt: Compare the execution plans for the two queries (query id 1 and query id 2 using Query Store. Highlight any differences in operators, estimated vs actual row counts, or implicit conversions. Running the following prompt : CPU Usage: Please, show the top resource-consuming queries in the current database using Query Store data. Include query text, execution count, duration, CPU time, and logical reads. We could see the impact of using an antipattern:
