My application runs off my database that I created. I added migration, update-database and all that jazz so that it works perfectly fine.
Now that I have to convert my project to use the LIVE database, I'm getting this error message:
Microsoft.Data.SqlClient.SqlException (0x80131904): Invalid column name 'NormalizedEmail'.
Invalid column name 'ConcurrencyStamp'.
Invalid column name 'LockoutEnd'.
Invalid column name 'NormalizedEmail'.
Invalid column name 'NormalizedUserName'.
Invalid column name 'UserType'.
I'm not sure how to go about fixing this but when I use my old database it works, with this new one it just keeps giving me this error when I try to log in a user or anything to do with my database.
Help please!
ThANK YOU!
Remove this columns from code
I think it's mismatch with database
look at this
The problem is very simple to state and very difficult to solve. But there IS a solution.
Manual solution
If all automatic approaches fail and you do not have any extra information, then you can at least ensure that your schema is technically compatible with the application's expectations.
Depending on the RDBMS that you use and which was not specified in the question, you can get all the table names and column names. In MySQL and PostgreSQL you could query information_schema.columns, in SQL Server you can join sys.tables and sys.columns for that purpose. Make sure that you order the results by tablename, columnname and export it. Do it both for your old db and prod db. Find out what the differences are and implement alter statements to add the missing columns.
Automatic solution
If you have some scripts versioned somewhere that were doing the alters and possibly filling the new columns with data, then run those either by hand or a migration tool. Make sure that if such files exist, then you find them.
Removal
You can also remove the column references from code, as Cemil suggested in his/her answer, but you should avoid doing this, unless you are absolutely sure that it is feasible for your situation. The basic assumption is that the code references these for a reason and you are missing the columns from the database where they need to be created. Do not remove the column references from code until this basic assumption is proven wrong.
Can anybody tell me what does the error mean? Whenever I open the query builder it will prompt with an error indicating that SQL syntax errors were encountered.
https://msdn.microsoft.com/en-us/library/ms189012.aspx
I looked at the following page in MSDN but I don't understand what it means...
For instance, what do these bullet points from the MSDN article mean?
The SQL statement is incomplete or contains one or more syntax errors.
The SQL statement is valid but is not supported in the graphical panes (for example, a Union query).
The SQL statement is valid but contains syntax specific to the data connection you are using.
USER (which you've apparently decided is an appropriate table name) is a SQL Server reserved word.
The best solution is to rename your table, so you don't have to escape the table name every time you want to query it and to make it clear it's your user data (hey, there's a table name suggestion - userdata).
The other option is to escape the name by surrounding it with square brackets:
SELECT * FROM [users]
Note that it will get old fast having to do this with every query. Again, the best solution would be to rename the table to something that isn't a reserved word.
I am trying to set the default value for a new column I just added. In properties I am trying to set 'Default Value or Binding' to a simple XML along the lines of:
<root>
<title>Welcome</title>
<body>Thank you for your time.</body>
</root>
However, when I click away, I get an error:
SQL error validating the default for column
I set this value in other numerical columns and it worked fine. What gives?
Not sure, but the visual designers in SQL Server Management Studio often don't quite work properly...
Just use a simple T-SQL statement to achieve the same thing:
ALTER TABLE dbo.YourTableName
ADD CONSTRAINT DF_YourTable_YourXmlColumn
DEFAULT '<root><title>Welcome</title><body>Thank you for your time.</body></root>'
FOR YourXmlColumn
and you're done!
(You didn't specify your table and column names - so I just made up placeholders - do replace those with your actual table and column names! Also: for the default constraint, I'd always recommend specifying an explicit name - makes it easier to disable and/or drop the constraint later, if you ever need to; my default naming convention is shown - again: adapt to your needs / likes)
It is true that knowing what TSQL command to run is advantageous in many ways but just to add an answer for SQL Server Management Studio so it is not swept under "it doesn't quite work properly", the syntax is ('[xml here]').
('<root><title>Welcome</title><body>Thank you for your time.</body></root>')
I'm trying to run a report in Access that references a poorly named column: Vendor#. For those of you not familiar with Access: '#' is a reserved keyword with special meaning. I've been trying to run the report and every time I do a popup appears asking for a value for the column: in other words it keeps seeing it as a variable name. I've tried a number of variations on the name including: [Vendor#], 'Vendor#', ['Vendor#']. I tried an Alias but then I encountered the same issue in the where clause referencing the Alias. No I can't change the schema to rename the column to something more appropriate. Any help is appreciated.
Here is the query:
SELECT * FROM dbo_Vendors
WHERE ((dbo_Vendors.[Vendor#]) = [Forms]![frm_Report_Vendor]![VendorNumber])
I have just tested with a linked sql server table having a column called Vendor#. I can create a report and it runs correctly.
Can you save the query and test that the query runs? I suspect that you may have a misspelled form reference, because I have tested the whole scenario and it works for me. I do not think the report has anything to do with it.
I've hit a bit of an impasse. I have a query that is generated by some C# code. The query works fine in Microsoft SQL Server Management Studio when run against the same database.
However when my code tries to run the same query I get the same error about an invalid column and an exception is thrown. All queries that reference this column are failing.
The column in question was recently added to the database. It is a date column called Incident_Begin_Time_ts .
An example that fails is:
select * from PerfDiag
where Incident_Begin_Time_ts > '2010-01-01 00:00:00';
Other queries like Select MAX(Incident_Being_Time_ts); also fail when run in code because it thinks the column is missing.
Any ideas?
Just press Ctrl + Shift + R and see...
In SQL Server Management Studio, Ctrl+Shift+R refreshes the local cache.
I suspect that you have two tables with the same name. One is owned by the schema 'dbo' (dbo.PerfDiag), and the other is owned by the default schema of the account used to connect to SQL Server (something like userid.PerfDiag).
When you have an unqualified reference to a schema object (such as a table) — one not qualified by schema name — the object reference must be resolved. Name resolution occurs by searching in the following sequence for an object of the appropriate type (table) with the specified name. The name resolves to the first match:
Under the default schema of the user.
Under the schema 'dbo'.
The unqualified reference is bound to the first match in the above sequence.
As a general recommended practice, one should always qualify references to schema objects, for performance reasons:
An unqualified reference may invalidate a cached execution plan for the stored procedure or query, since the schema to which the reference was bound may change depending on the credentials executing the stored procedure or query. This results in recompilation of the query/stored procedure, a performance hit. Recompilations cause compile locks to be taken out, blocking others from accessing the needed resource(s).
Name resolution slows down query execution as two probes must be made to resolve to the likely version of the object (that owned by 'dbo'). This is the usual case. The only time a single probe will resolve the name is if the current user owns an object of the specified name and type.
[Edited to further note]
The other possibilities are (in no particular order):
You aren't connected to the database you think you are.
You aren't connected to the SQL Server instance you think you are.
Double check your connect strings and ensure that they explicitly specify the SQL Server instance name and the database name.
In my case I restart Microsoft SQL Sever Management Studio and this works well for me.
If you are running this inside a transaction and a SQL statement before this drops/alters the table you can also get this message.
I eventually shut-down and restarted Microsoft SQL Server Management Studio; and that fixed it for me. But at other times, just starting a new query window was enough.
If you are using variables with the same name as your column, it could be that you forgot the '#' variable marker. In an INSERT statement it will be detected as a column.
Just had the exact same problem. I renamed some aliased columns in a temporary table which is further used by another part of the same code. For some reason, this was not captured by SQL Server Management Studio and it complained about invalid column names.
What I simply did is create a new query, copy paste the SQL code from the old query to this new query and run it again. This seemed to refresh the environment correctly.
In my case I was trying to get the value from wrong ResultSet when querying multiple SQL statements.
In my case it seems the problem was a weird caching problem. The solutions above didn't work.
If your code was working fine and you added a column to one of your tables and it gives the 'invalid column name' error, and the solutions above doesn't work, try this: First run only the section of code for creating that modified table and then run the whole code.
Including this answer because this was the top result for "invalid column name sql" on google and I didn't see this answer here. In my case, I was getting Invalid Column Name, Id1 because I had used the wrong id in my .HasForeignKey statement in my Entity Framework C# code. Once I changed it to match the .HasOne() object's id, the error was gone.
I've gotten this error when running a scalar function using a table value, but the Select statement in my scalar function RETURN clause was missing the "FROM table" portion. :facepalms:
Also happens when you forget to change the ConnectionString and ask a table that has no idea about the changes you're making locally.
I had this problem with a View, but the exact same SQL code worked perfectly as a query. In fact SSMS actually threw up a couple of other problems with the View, that it did not have with the query. I tried refreshing, closing the connection to the server and going back in, and renaming columns - nothing worked. Instead I created the query as a stored procedure, and connected Excel to that rather than the View, and this solved the problem.
