i have 2 working databases. one is called EquipmentDB one is called EmployeeDB

I created another form. I want to key in the Company ID of the employee in the textbox and click a Button. The rest of the details of the employee will display in textbox or label as followed:


P.S: i have 2 of this field in my database.

After that there will be another textbox to type in the barcode of the equipment. Same thing, click a Button display the barcode details.


Is it possible to use 2 database in one form?

If you have your databases on different servers you can use two connection strings. But if you have your databases on the same server you can pass database name as a variable to your stored procedure and there you can create a dynamic query. For example:

Create Procedure CompanyDetails
(@companyID int,@databaseName varchar(50))
declare @sql varchar(500)
set @sql = 'select * from ' + '[' + @databaseName +'].dbo.CompanyDetailsTable where companyId = ' + Convert(varchar(10),@companyID)
exec @sql
