I am trying to add a computed column to a table via SSMS - I'd rather care not to get into the details on why the base column is a VARCHAR(10) and not a DATE and no, I'm not interested in changing it.
When I enter the formula CONVERT(DATE, [charDob]) in the table designer SSMS reports:
Error validating the the formula for column charDobTyped.
Using the formula [charDob] "works" as expected, meaning the column is bound correctly. Also the formula CONVERT(DATE, '2001') "works" as expected - so there is something with using the column that is causing the error.
The original column is a VARCHAR(10) and contains NULL values or values that are otherwise convertible to DATE. The query SELECT CONVERT(DATE,charDob) as dob FROM people works as expected. Also, the error message is about "invalid formula" and not about a data conversion error, so I don't believe that inconvertible is causing this.
I have already saved the table with the new computed column and a dummy value and reconnected to the database - this was to ensure that there was not an odd caching issue occurring, as sometimes occurs. The error persists independent of the persisted flag - if only it were that easy to turn off.
Management Studio is not the best way to perform most DDL. Please open a new query window and use:
ALTER TABLE dbo.whatever ADD newcolumn AS (CONVERT(DATE, CharDob));
Here is the specific bug:

"Next release" in this context is most certainly SQL Server 2012, so if you are using 2008 or 2008 R2 SSMS (why?), the fix won't apply to you.

In SQL server, I have a table with 'smalldatetime' data type for one of the column. When I am trying to export the data using Microsoft SQL server import/export wizard, it is giving me conversion error because the field contains NULL value in Date field. Can you please help me in resolving this error.
What steps need to be followed in order to resolve the conversion error.
Are you trying to copy "table to table" or "query to table"?
Cause if your problem is only with null values you can write a query and use ISNULL() function.
Can you post the error here? I´m asking cause maybe your problem isn´t it. Maybe you´re trying to convert a type into another that is not compatible.
I've been using phpMyAdmin to manage my db without any problem, but today I ran into this error if I try to add any column by using the interface to any table of any database:
ALTER TABLE `testing` ADD `faaa` INT NOT NULL AFTER ;
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
But if I add the column via SQL command in phpMyAdmin, this time by removing AFTER, the column is added without any problem.
I'm still inexperience with phpMyAdmin, so I guess I must have missed a mandatory field to fill when creating a new column in the interface. Can anyone shed a light on this for me?
AFTER column_name is used to designate which column in the table you want to insert the new column after. You're providing the AFTER without telling it which column you want the new column to be inserted behind. If you don't care about the order of the columns in your table, omit the AFTER, and the new column will be inserted at the end of the column list.
You have no column name after the AFTER statement, so the phpMyAdmin doesn't know where it should be put. Whether it's you forgetting to select the column or a phpMyAdmin bug, I have no idea because for adding a new column, the only required fields are the name and type, which you have.
I have an ssis package created in vs 2005 that has started to give me the following error:
[Lawson Staging Table [4046]] Error: There was an error with input column "JOB_CODE" (4200) on input "OLE DB Destination Input" (4059). The column status returned was: "The value violated
the integrity constraints for the column.".
My first question is: what are the 4046, 4200 & 4059 values following my table, column and destination?
My second question is about the integrity constraint message. The destination table is a heap (no keys or indexes) with no constraints. The destination column is defined as a varchar(10). The input column is from oracle, is defined as char(9) and is called job_code. So - where is there an integrity constraint defined?
The final question is about the select statement; looks like the following:
Select ...
,lpad(trim(e.job_code),10,'0') as job_code ...
If I take the lpad and trim functions out, it works but I need these functions in place because my spec calls for a fixed length column padded with leading zeros. This column returns data as expected in TOAD but fails in the ssis package. Does anyone see an issue with how the functions are being used?
Since this package worked in the past but suddenly started to throw this error, I'm assuming that new invalid data has come into play. however, recently added rows don't seem to be any different then historical records.
Those numbers are more likely to be the ids assigned to the each task/table/column etc.
You could probably go to the advanced editor of the data flow task and look at the input and output properties. You can see that for each input or for each column there is an ID assigned.
Next: The error that you are getting occurs usually when "Allow Nulls" option is unchecked.
Try this:
Look at the name of the column for this error/warning.
Go to SSMS and find the table
Allow Nulls for that Column
Save the table
Rerun the SSIS
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.
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.
