We're using two schemas in our project (dbo + kal).
When we are trying to create a view with the following SQL statement, Visual Studio shows as an error in the error list.
CREATE VIEW [dbo].[RechenketteFuerAbkommenOderLieferantenView]
AS
SELECT
r.Id as RechenkettenId,
r.AbkommenId,
r.LieferantId,
rTerm.GueltigVon,
rTerm.GueltigBis,
rs.Bezeichnung,
rs.As400Name
FROM
[kal].[Rechenkette] r
JOIN
[kal].[RechenketteTerm] rTerm ON rTerm.RechenketteId = r.Id
JOIN
[kal].[Basisrechenkette] br ON rTerm.BasisrechenketteId = br.Id
JOIN
[kal].[Rechenkettenschema] rs ON rs.Id = br.Id
WHERE
r.RechenkettenTyp = 0
The error message looks like this:
SQL71501: Computed Column: [dbo].[RechenketteFuerAbkommenOderLieferantenView].[AbkommenId] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects:
[kal].[Basisrechenkette].[r]::[AbkommenId], [kal].[Rechenkette].[AbkommenId], [kal].[Rechenkette].[r]::[AbkommenId], [kal].[Rechenkettenschema].[r]::[AbkommenId] or [kal].[RechenketteTerm].[r]::[AbkommenId].
Publishing the view and working is just fine, but its quite annoying to see the error message all the time when building our project having all the serious errors get lost in the shuffle of those sql errors.
Do you have any idea, what the problem might be?
I just found the solution. Although I can't read your (what appears to be German) enough to know if you're referring to system views, if so, a database reference to master must be provided. Otherwise, adding any other required database references should solve the problem.
This is described here for system views: Resolve reference to object information schema tables
and for other database references.

For me I was seeing SQL71501 on a user defined table type. It turned out that the table type's sql file in my solution wasn't set as build. As soon as I changed the build action from None to Build, the error dissapeared.
I know this is an old question but it was the first one that popped up when searching for the error.
In my case the errors were preventing me from executing the SqlSchemaCompare in Visual Studio 2017. The error however was for a table/index of a table that was not part of the solution any more. A simple clean/rebuild did not help.
A reload of the visual studio solution did the trick.
We have a project that contains a view that references a table valued function in another database. After adding the database reference that is required to resolve the fields used from the remote database, we were still getting this error. I found that the table valued function was defined by using "SELECT * FROM ..." which was old code created by someone not familiar with good coding practices. I replaced the "*" portion with the enumerated fields needed and compiled that function, then re-created the dacpac for that database to capture the resulting schema, and incorporated the new dacpac as the database reference. Woo Hoo! the ambiguous references went away! Seems that SSDT engine cannot (or does not) always have the ability to reach down into the bowels of the referenced dacpac to come back with all the fields. For sure, the projects I work on are normally quite large, so I think it makes sense to give the tools all the help you can when asking them to validate your code.
Although this is an old topic, it is highly ranked on search engines, so I will share the solution that worked for me.
I faced the same error code with a CREATE TYPE statement, which was in a script file in my Visual Studio 2017 SQL Server project, because I couldn't find how to add a user-defined type specifically from the interface.
The solution is that, in Visual Studio, there are many programmability file types, other than the ones you can see through a right-click > Add. Just select New Element and use the search field to find the element you are trying to create.
From the last paragraph of the blog post Resolving ambiguous references in SSDT project for SQL Server, which was linked in the answer https://stackoverflow.com/a/33225020/15405769 :
In my case, when I double clicked the file and opened it I found that
one of the references to ColumnX was not using the two part name and
thus SSDT was unable to determine which table it belonged to and
furthermore whether the column existed in the table. Once I added the
two part name. Bingo! I was down to no errors!
In my case, I got this error when I was trying to export the datatier application. The error was related to the link on a database user. To solve the problem, you need to log in to the server with read rights on system users.
In my case I just double click on the error and it will take me to the exact error on procedure and I noticed that table column is deleted or renamed but in SP its still using the old column name.
If you build an SSDT project you can get an error which says:
“SQL71502: Function: [XXX].[XXX] has an unresolved reference to object [XXX].[XXX].”
If the code that is failing is trying to use something in the “sys” schema or the “INFORMATION_SCHEMA” schema then you need to add a database reference to the master dacpac:
Add a database reference to master:
Under the project, right-click References.
Select Add database reference….
Select System database.
Ensure master is selected.
Press OK.
Note that it might take a while for VS to update.
(Note this was copied verbatim from the stack overflow question with my screenshots added: https://stackoverflow.com/questions/18096029/unresolved-reference-to-obj… - I will explain more if you get past the tldr but it is quite exciting! )
NOT TLDR:
I like this question on stack overflow as it has a common issue that anyone who has a database project that they import into SSDT has faced. It might not affect everyone, but a high percentage of databases will have some piece of code that references something that doesn't exist.
The question has a few little gems in it that I would like to explore in a little more detail because I don't feel that a comment on stack overflow really does them justice.
If we look at the question it starts like this:
If you're doing this from within Visual Studio, make sure that the file is set to "Build" within the properties.
I've had this numerous times and it really gets me everytime. SQL Build is case sensitive even though your collation isn't. Check the case is correct in agreement with the object and schema names that are referenced!

I have a very strange 'reload.sql' file that I need to use to build a database.
It references about 200 XXX.dat files with straight-up readable data (although useless without explanations regarding the meaning of the fields).
I have tried msssql server, mysql workbench (on a server local-hosted on wamp), and directly accessing it through DBeaver and IBConsole, but I cannot manage to execute/build it.
It uses a weird syntax. There are elements like
begin
...
end
go
that hinted me towards T-SQL, but using sqlcmd on it gave me thousands upon thousands of errors regarding keywords.
Specifically, the very first batch of executable lines says
SET OPTION date_order = 'YMD'
go
SET OPTION PUBLIC.preserve_source_format = 'OFF'
go
SET TEMPORARY OPTION tsql_outer_joins = 'ON'
go
SET TEMPORARY OPTION st_geometry_describe_type = 'binary'
go
SET TEMPORARY OPTION st_geometry_on_invalid = 'Ignore'
go
SET TEMPORARY OPTION non_keywords = 'attach,compressed,detach,kerberos,nchar,nvarchar,refresh,varbit'
go
which generates about 150 errors 'Incorrect syntax near OPTION keyword' on its own, and according to google is part of a 'rexx' procedure but 'date_order' should then be 'DATFMT', right?
Another track is that of SyBase, but I cannot for the life of me get it to work (through my trials I did manage to build a .db file, that, well, is useless to me since I can't build it either..).
I've tried accessing it through ODBC pilots as well but none worked (the paradox ODBC did not crash, but said there was an error with a FROM clause, which are generated automatically...).
I need to know a way to build a database from this file or directly access the data it references, which I can't really post since it contains private medical data.
Also what madman came up with this.
The very first google link (for me anyway) against 'st-geometry-describe-option' shows this is a SAP SQL Anywhere database i.e. http://dcx.sybase.com/1200/en/dbadmin/st-geometry-describe-option.html
So I would suggest starting from the SQL Anywhere documentation and you will need to install the database software beforehand.
I have very basic skills in developing SSIS packages; and getting errors while developing this new package. With this package, the SQLInstance is getting determined fine as can be seen in column mapping in the second picture. But it is not reading columns from the columns of a user table (IndexType column, in this case). This is the issue.
Tried below steps with no luck till now:
I set the VaidateExternalMetaData setting to False, still same error.
Already removed all columns one-by-one to identify whether it is issue with some specific data type, still same issue.
Created a brand new test package, same error in test package also.
Another package working fine in production with same settings with a user database. Copied the DataFlowTask component from it and used it new package, still same issue.
Please help. Many thanks.
It may be SQL server version. I had similar issue when using table variables or temp tables. You need to use with result set, similar to this:
EXEC('SELECT 43112609 AS val;')
WITH RESULT SETS
(
(
val VARCHAR(10)
)
);

SQL can not tell what is being returned when using temp/table variablbes so you have to specify this. It is needed for some versions of SQL Server.
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.
I am trying to generate some insert scripts using the SQL Server 2008 Script Wizard. Upon generating the scripts, I get the following error:
"The selected database contains foreign keys that create a cycle. Publishing data only is not supported for databases with cyclical foreign key relationships."
I've attempted to disable and remove all constraints in the database. The error is still occurring. Is there any way to get around this? Possibly make SQL ignore the constraints while generating the scripts.
On the Wizard page where you choose the radio button to select All Database Objects or Specific Objects, make sure to select All Database Objects. For some reason the tool needs something in there to generate even if you just want the table insert script.
Once I changed that radio button to All Database Objects, and selected the Advanced option to generate Type of script = Data Only, it worked all the way through.
I had the same problem as the OP. Then I tried again, this time in the advanced options, for the "types of data to script" option, I selected "schema and data" rather than data only. Then it worked for me without complaining about cyclical keys.
I was having the same issue, and I discovered today that you can use SQL Server Management Studio 2012 against a 2008 R2 DB and you won't get the error:
Sql Server Scripting Data Only: Workaround for CyclicalForeignKeyException?
Saving to file vs. to a new Query editor window seems to make it work for me on Management Studio 2008 :\
First off IMHO HLGEM's response is a bit cavalier--there are valid reasons at times to have cyclic references.
That said I think the script generator is hyper-sensitive. It seems to think just about any PK/FK pair is "cyclic" and I ended up having to use a copy of my database from which I'd stripped all keys to get the export to get beyond the "cyclical" error. A script like the following can help you drop keys globally but of course be careful!
SELECT
'ALTER TABLE ' + object_name(parent_obj) + ' DROP CONSTRAINT ' + [name]
AS Script
from sysobjects where xtype IN ('F')
[I didn't write this. See http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=46682]
Further the tool is pretty useless in terms of feedback since its report doesn't provide enough detail to narrow down where the supposed cyclical references exist.
Finally I found the tool to be pretty flaky in that I get random timeouts. One other observation that I haven't researched extensively is I think the tool may require you to start from scratch after the cyclical error to clear it's cache since I see different behavior when I use Previous button vs. starting afresh.
You can export the data by setting the script option - "Script Check Constraints" to False
Sorry this will not work :(
You will have to determine which table is causing the issue.
I was getting the same error because I didn't had a table selected in the object list (one big table I wanted to create in another script). Selecting all of the tables solved the problem.
PD: Maybe a little bit late, but searching CyclicalForeignKeyException gets first in Google.
Does anyone have an idea what this error means or how to solve it? I am using Access 2003 and SQL2005. It comes up when trying to add a record on a particular subform.
[Microsoft][SQL Native Client] Invalid character value for cast specification (#0)
This MS bug report describes the same message, but it is a bug in SQL Server 6.5 that has already been solved.
Solved: Apparently having no PK on the destination table was causing this, it didn't have anything to do with the subform or the query from Access. I wasn't even aware there were tables in this database without PK. Adding PK to the destination table solved it. The strange thing is the same query string that errored when executed via SQL native client, executed through SSMS with no errors. Hope this helps anyone else who has come across that strange message.
Hum, I would check the text box default on the access side. I would also bring up the linked table in design mode, and you want to check the data type that ms-access assumes here. For non supported data types ms-access will generally use a string, and sql server might be wanting something else.
So, check both the Primary key (PK) in main table, and then check the data type used (assumed) in the child table for the foreign key (FK) column. While we are at this, check your expressions used for the child/master link settings in the sub-form control (not the form, not the sub-form, but the sub-form control used in your form that links up these two tables).
Sub forms in access are sensitive if you don’t have a timestamp column in the sql server table. As mentioned check the PK and the FK data types and make sure they match up (just bring up the tables in design mode in ms-access -- you get an error message about the design mode being read only, but just continue on so you can check/view to ensure the data types match up).
So for the child table, you need a PK, a FK, and also a timestamp column (you don’t have to display the TS column in the sub-form, but you need it in the table).
Sub-forms in ms-access are sensitive and often fail if you don’t include a timestamp column in the sql table. (access uses these row version columns to determine if the data been changed).
Is one of your fields in the view calculated/built with the CAST function? In this case, you might not have the right to update/add a value for that field.
Can you execute your view in the MS SQL Studio interface and try to insert a record?
Another cause to this issue is that if you change a table name without alterting the view then the "Dependencies" of that view still remians with the table old name.
Let say I have a table 'A' and a view 'Av' which derives from 'A', and I created a new Table which will be named 'A' and I changed 'A's name to 'A_old' but I didn't executed an ALTER VIEW, so the dependencies of 'Av' still remain on 'A_old' but the view is derives from 'A' and it cuasing this Error in Access when trying to open the view as a linked table
I just spent a day battling this with an Access ADP project that was imported into a new Access 2016 ACCDB file. Initially I figured it was an issue with the application code, but I was getting this keying records directly into the table. Interestingly, the records always got written - it seemed to be the read-back that was triggering the error. Profiling the insert sql and running that from SQL Management Studio worked without any issues.
The table that was causing the problems had a GUID Primary Key. Switching that to an int column resolved the issue.
The SQL database was also littered with a few thousand extended properties which I removed before switching the PK. There was a strong suggestion from the web that these cause problems. The source of that process is documented here: Remove All SQL Extended Properties
I had this problem with Access 2016 trying to update an ODBC linked sQL Server database. Problem was a null value in field used to join the two tables. Eliminating the null value solved the problem
OK I just had this bad experience and it had nothing to do with PK or any of this stuff in my situation. The view that reported this problem in Access was created in SQL Server originally and used a CAST of DATETIME to plain old DATE to get rid of the unneeded time part. Up until today this view had caused 0 issues in Access, but started to generate heartburn just as described above.
So, I generated a Drop/Create script for the MSS view, ran it, relinked the views in Access, and the Access database was happy with the result. All my so-called tables in Access are basically views through links to MSS for reporting. I only have 1 table that actually does changes. Other than that, I do not edit through views in Access.
The message is of course useless as usual but this was my solution in my situation.
Based solely in the message you provided above, it appears that you are trying to set an invalid value to some field or parameter, etc... The message is telling you that it is trying to convert a value into an specific data type but the value is invalid for that data type... makes sense?
Please add more details so we can help you better.
