The recordset field is called and then assigned to sContactID where a couple of "trims" will take place to get rid of extra characters.

The code to transmit the data via DAO will also use the UserID from dbo_UserSecurity, but it will be within a DAO recordset. This results in an Error if we let the execution continue.Įrror message from MS Access when cmd (ADODB.Command) attempts to execute the stored procedure. When we pause it, we see a string of question marks ("?"). Putting a break on the line below our UserID parameter to be passed, we can pause the execution of the code to view what the value of the sContactID variable is. ActiveConnection = "Provider=MSDataShape Data Provider=SQLOLEDB SERVER=YourSQLServerName ĭATABASE=AdventureWorks Integrated Security=SSPI" SContactID = Nz(DLookup("userId", "dbo_UserSecurity", "UserName = '" & Me.username & "'"), "") Retrieving GUID data from Linked SQL Server TableĬreate a table in SSMS where MS Access will process and send the data (an INSERT action via a Stored Procedure that we will write). The userid data field shows that it appears to Access to be a number with a field size of ReplicationID. Although you can create a user defined type and create your own GUIDs, you will still have the issue of the way that DLookup interprets the data from a table: Numeric, Text, or Date). The newID function takes care of creating the uniqueidentifiers for me so I don't have to create them.Ī simple SELECT statement verifies the successful creation of the table and that the table has been populated with data.īy getting External Data (ODBC) and linking to the table, UserSecurity, in MS Access, I can verify the data types that are being interpreted by MS Access (since MS Access does not have an equivalent GUID data type builtin. I create the table and insert some data using the statements below in SSMS using the AdventureWorks database. This table has a GUID (SQL uniqueidentifier) in it along with other fields. Suppose there is a SQL Server table that I want to link to in my MS Access database. SQL Table with uniqueidentifier Data Type in MS Access

LngCounter = DLookup("", "tblLogger", "ID=1") Here is the code used when you click the corresponding buttons (you can add or subtract from lngCounter to fit the button) Private Sub btnG_01_Click() The similar functionality happened when you clicked on the orange, blue, and purple buttons. So if the green “+10” button was clicked, 10 got added to the value of the table and was displayed in the form’s label. The data was saved and read from this table: Here is what part of the form looked like: So I had an interesting question come my way today via the chatbox on this website.īasically it was to increment a value in a label based on the button that was clicked.
