Instead, in your table set your date/datetime fields to accept nulls and simply do not send any value for those fields or explicitly send null.Another alternative would be, to execute "SET NULL OFF" on the same connection.

UPDATE summary_data SET current_category = (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id) WHERE EXISTS (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id); If you want to test your skills using the SQL UPDATE statement, try some of our practice exercises.

These exercises allow you to try out your skills with the UPDATE statement.

When you do that, any fields that you do not pass are filled with their "default blank" values (0 for numeric, for date etc).

Updating a field with '0000-01-01' is simply asking for trouble (recently I had to deal with a customer's table giving headache and it turned out that someone did the same you did, putting table in an unusable state - hard to catch and fix).

Hi, I have a problem where I need to update an Access database from Ms Excel.

I have chosen to use an ADODB connection as I'm familiar with writing SELECT statements and accessing data this way.

Execute n SQL & n JOIN Msg Box "Uploaded Successfully" wbk Open.

OLEDB.12.0; Data Source=" & str File Name & "; Extended Properties=""Excel 12.0 Xml; HDR=Yes"";" n SQL = "INSERT INTO [odbc; Driver=; Server=*Server Name*; Database=*Database Name*].*Table Name*" n JOIN = " SELECT * from [Temp Range]" cnn.

The following fails if there is also a Date type field in that record.

ADO is ANSI based and there is no "empty date" concept there.

After opening the record Set, and selecting some records, I need to update the values in the Record Set then save those changes back to the table but I can't figure out the format/type to use when using Ado's Recordset 'Update' method.
