Im having to edit code in very old classic asp.
Im comparing two values.
I am getting an error saying Type mismatch
This is where it occurs:
if oRsDropDown(id_col) = variable then
the drop down is created form a sql execution
I think the issue may be that the ID column in the db being compared is a big int?
Without knowing the type that oRsDropDown returns, does it work with is?
if oRsDropDown(id_col) is variable then

I build a dynamic Dictionary in ClickHouse DB. It will create the dictionary before the SQL commands execute. Also, the dictionary name was created at the same time.
The dictionary name was a combined string by date and table name. Because I don't want to keep so much data in the long-term dictionary, the short-term Dictionary could be a great help to release the memory after maybe an hour when no one is using it.
And the error happened.
When I use the dictionary in my SQL commands it is okay with solid commands.
e.g.
dictGet(CONCAT('2022-04-06', 'MyTableName'), 'GetBackColumnName',myKeyColumn) AS col_name
But when I change to using the column from Table, it was broken.
e.g.
dictGet(CONCAT(DATE_COL, 'MyTableName'), 'GetBackColumnName',myKeyColumn) AS col_name
And the error message shows up.
Illegal type String of the first argument of function dictGet,
expected a const string.
Does anyone know how to fix the issue?
My CH version is: 20.8.7.15
I try to find the resolution from the ClickHouse office report but nothing can fix this issue. And I tried lots of functions of String to figure out what happened.
Hello everyone and happy new year,
I'm converting my project to use SQL Server instead of MySQL and I'm struggling with the problem of managing timestamps.
In the project, I have this code:
Customers::whereBetween('created_at', [Carbon::now()->subDays('7'), Carbon::now()])->count();
which gives me back the number of new customers registered in the last 7 days.
Using MySQL no problem whatsoever while with SQL Server I get this error:
Converting an nvarchar data type to datetime resulted in a value
outside of the allowable range.
despite in my model, I have set
public function getDateFormat()
{
return 'Y-m-d H: i: s.v';
}
to get the values in milliseconds.
What did I forget to set up?
The error tells you that a conversion failed. Possible reasons:
The date does not exist
If you get February 30th as the input, it will fail.
Input not complying to the format in use
To detect whether this is the problem, you will need to find out what the generated SQL is and find out which value caused this problem. After carefully studying the conversion you should be able to determine what the problem and solution is.
We use VBA to retrieve data from an Oracle database using the Microsoft.ACE.OLEDB.12.0 provider.
We have used this method without issue for a long time, but we have encountered a problem with a specific query of data from a specific table.
When running it under VBA, we get "Run-Time error '1004': Application-defined or object-defined error. However investigating further, we find the following:
The queries we run are dynamically generated, and how we handle them is to read the results into a variant array, then output that array into Excel. When we step-through our particular query, we find that one specific database field is "blank": The locals window shows the value to be completely blank: it is not an empty string, it is not a null, it is not zero. VarType() shows it to be a decimal data type, and yet it is empty.
I can't seem to prevent this error from locking-out:
On Error Resume Next
...still breaks.
if (isEmpty(theValue)) then
...doesn't catch it, because it is not empty
if (theValue is nothing) then
...doesn't catch it because it is not an object
etc.
We used the SQL in the a .NET application, and got a more informative error:
Decimal's scale value must be between 0 and 28, inclusive. Parameter name: Scale
So: I see this as two issues:
1.) In VBA, how do I trap the variant datatype value-that-is-not-empty-or-null, and;
2.) How do I resolve the Oracle Decimal problem?
For #2, I see from the Oracle decimal data type, it can support precision of up to 31 places, and I assume that the provider I am using can only support 28. I guess I need to Cast it to a smaller type in the query.
Any other thoughts?
I'm working with an open source database. I'm trying to map it to classes with DataMapper, and later I'm going to make changes in a Model driven approximation instead of a Database driven one.
But first I would like to map the open source database in an exact way. This database is a PostgreSQL one and in some tables there are some fields with a character type.
How can I map character type in DataMapper? This type it's not in its primitive types, nor in dm-types, nor in dm-types-legacy.
If it gives more information, actually I'm not writing the model by hand but I'm using dm-is-reflective, which automatically maps an existing database table. It gives me following error:
/var/lib/gems/1.9.1/gems/dm-is-reflective-1.0.0/lib/dm-is-reflective/is/adapters/data_objects_adapter.rb:141:in `reflective_lookup_primitive': bpchar not found for DataMapper::Adapters::PostgresAdapter (TypeError)
EDIT
It was a problem with dm-is-reflective and not with datamapper core, which can work well with char type as a String type with a length set. I answer with the solution to the problem.
godfat, the man working in dm-is-reflective quickly solved this issue :) Many thanks to him!

I currently have an existing database and I am using the LINQtoSQL generator tool to create the classes for me. The tool is working fine for this database and there are no errors with that tool.
When I run a LINQ to SQL query against the data, there is a row that has some invalid data somehow within the table and it is throwing a System.FormatException when it runs across this row. Does anyone know what that stems from? Does anyone know how I can narrow down the effecting column without adding them one by one to the select clause?
Do you have a varchar(1) that stores an empty string?
You need to change the type from char to string in the designer (or somehow prohibit empties). The .net char type cannot hold an empty string.
