Hi, Welcome to Microsoft Q&A.
A possible cause of this problem is that the fields in the database do not match the data types of the parameters passed to the query.
Please make sure that the data type of each parameter matches the data type of the target column.
For example, to convert a string to a numeric format in an Access database, you can use conversion functions such as Convert.ToByte
, Convert.ToInt16
, Convert.ToInt32
, Convert.ToInt64
, Convert.ToSingle
, Convert.ToDouble
, Convert.ToDecimal
, and so on.
Best Regards.
