When working with database transactions, some operations can produce errors, and errors can result in unpredictable operations, especially in bulk transactions. In order to avoid this situation, it is necessary to control the data connection and handle the error information in the database transaction accordingly. 1. Database error message let's look at the error message of the database first. Here, using an Access file dbcon.accdb as the target database, in the collector, create a new ODBC da

Four, the test use vs in theDataGridView Test, first connect vs Same as the table we created in the Access database. Summary: What is the difference between establishing a connection without using an ODBC data source, and directly estab

Run in an Access database and find the results can be queried. This is run on the database. SELECT * from kpproj where kpname like ' * Test * ', but the same statement is empty in a C # program.

experience, like in access needs to use the * number, but the standard % should be used in SQL Server oracle databases. Why can't this happen at this time? After searching for information, I found that the access driver was connected. Previously I used mdb, and the database was accdb. Then I used the win7 64-bit development system, because Access in my program uses the oledb driver, "*" cannot be used here
