问题 How would I run an INSERT SQL query in Microsoft Access? For Example: INSERT INTO tbl_UserPurchase (ID, Name) Values (321, Joe) 回答1: You can build your query in Access' query designer, then while still in Design View, click "Run" on the ribbon.

A simplified version of the code is below (I've stripped out error handling & a couple more

问题 I have an excel spreadsheet that contains the primarky-key/id value for a record in a table in an access database.

问题 I'm migrating an Access database to SQL Server using the SQL Server Migration Assistant (SSMA). The Access application will continue to be used but with linked tables instead of local ones. I've run into a problem during the post-migration testing with a form that contains several sub forms.

问题 I'm inserting a few rows in a table via OleDB, and select instantly the inserted row. I can't retrieve the row in this way, i have to wait for approx. 3-5 seconds. And then the inserted row appears in the table. I observed this behavior in the database itself, i inserted the row via OleDB and watched the opened table in Access. The row appeared 3-5 seconds later in the table. Does Access buffer rows? Do i have to send a flush or commit, etc. via OleDB ? Any suggestions would be very helpful.
