kandi X-RAY | ADOdb Summary
PHP’s database access functions are not standardized. This creates a need for a database class library to hide the differences between the different databases (encapsulate the differences) so we can easily switch databases. The library currently supports MySQL, Firebird & Interbase, PostgreSQL, SQLite3, Oracle, Microsoft SQL Server, Foxpro ODBC, Access ODBC, Informix, DB2, Sybase, Sybase SQL Anywhere, generic ODBC and Microsoft’s ADO. We hope more people will contribute drivers to support other databases.

QUESTION
I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.
Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.
Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.
I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.
This is my code:

-function in you SQL (as Nathan_Sav suggested as a comment): There is a IsNull
-function in VBA. With that, you can create a simple function that returns for example an empty string (or a 0 or whatever you prefer):

...ANSWER
Answered 2021-Jun-15 at 12:50You can't pass variables to the JScript, only variables created in the JScript can be accessed in the VBscript (for whatever reason this is how it is).
I recommend you create the entire process in VBScript as the functions in JScript can be done in VBScript and you won't have any problems.

QUESTION
Using Excel VBA, I am trying to search through an SQLite table for names that appear in a filename.
In the code below, I have the NamesFound collection object to store the names.
When I loop through the recordset, I can add names to NamesFound and print them.
After the recordset is closed and variables are destroyed, when I print the number of items in the collection (NamesFound.count), I get a number that matches the number of matching names in the filename.
However, when I try to print any of the elements in the collection, I get the error message "Object is no longer valid".
Any idea why this happens?

QUESTION
I am trying to update a row in a table in my database, which is of data type: date
.
I am using a stored procedure, and I am retrieving the value to update to from a TextBox as a string. My problem is that a string has double quotes (") and when I'm passing my value in the string, it keeps the double quotes and SQL-Server only supports single quotes ('').
ANSWER
Answered 2021-May-13 at 00:32You should be using Parameter
objects, not concatenating strings - you are passing the literal value sessionDate
, not your local sessionDate
variable's value.
SQL Server uses single quotes to delimit strings, so I'm not sure why you are using double quotes here, and you could double them up to escape them but not nudging you away from that direction would be unwise.
Make the CommandType
be adCmdStoredProc
, and the CommandText
should be just the name of the stored procedure - then use the Command
object to create and append the Parameters

QUESTION
I'm working with 2 different DB, one is an SQL server and the other is a MySQL.
I'm trying to cross the data between them. The 2 DB have one reference of product in common. But both use very different data.
For example in Mysql I have simple data like, description, price, type .... And in SQL I have Last price used, discounts, barcode .... But there are some products that don't have data in both DB, so they have to remain empty in some fields. And I Have to cross this data into a ListView.
I have this code so far:
...ANSWER
Answered 2021-May-11 at 17:11I separated the data access code from the user interface code. This will make your application easier to maintain. The database functions are passed values so they are not dependent on where the values come from. The user interface is not dependent on where the data comes from. It could be a text file, a web service or any kind of database.
I dumped the ADODB and recordset which are very old technologies and used straight ADO.net. This will require an imports for the MySql provider.
QUESTION
I am currently delving into parameterized queries with classic ASP and a MySQL database. I have an old page where visitors can search the database using a variety of hierarchical dropdowns that are populated from the database (e.g., Country, State, County). So the content of each dropdown will be filtered based on the selections made with the other dropdowns (7 total). I am trying to convert this page so that it uses parameterized queries.
In searching around the web, I think I have the steps necessary to create the queries correctly, but I am getting the following error.
Microsoft VBScript runtime error '800a01b6' Object doesn't support this property or method: 'Parameters.Append'
My code for the County dropdown is below.
...ANSWER
Answered 2021-May-07 at 16:44As @Flakes and @user692942 point out above, the append method does not take an assignment (=) so the correct solution to fixing the original error should be to write the append statement as follows:
