In this article, we explain you the four most common errors you may get when trying to run append query.
Append Queries in MS Access can be of great help when you want to copy or insert data in a table, although it is one of the most commonly used action queries in the application, there are still lots of doubts around its usage. We might be making use of this query on a frequent basis but there might still be occasions when we are unable to understand how to deal with errors that arise when working with these queries. To help make it easier for you to deal with errors arising when working with Append queries, we are going to give you some tips and explanations.
We will start off by explaining the 4 most common errors that you are likely to experience when running Append queries in MS Access. The “can’t append all records in the query” error occurs in MS Access due to:
Type Conversion Failure
If the field you are trying to append data from has a data type different to the field you are appending data to, you will come across an error. If you are trying to append data from textual field to another field that has its data type set to numbers, you obviously will not be able to complete the append process. Make sure you check the data type for fields before you append them.
If you are attempting to append data to fields of the tables that consist of the primary key, you need to first check the destination table. This needs to be done to check if the ‘No Duplicate’ property has been set to “Yes”. If this is true in your case, then you will have to check that the data you are attempting to append is not violating the destination table rules in any way.
One of the very common and simple reasons behind a failure in using Append queries is also because there is one user accessing the destination table over the network, and the other one has it open in Design view. This can lead to record locks which will not allow the query to append records to a table. So one of the key things you need to keep in mind is that while you are trying to append queries, the users should preferably be closed out from the database.
Validation Rule violations
To check what are the existing validation rules, go to the destination table design. If the required field is not there in your query, you will most likely get the error. And while you are at it, also give a look to the Text fields to check the status of ‘Allow Zero Length’ property. If it is set to No, and your query is not trying to append characters in this field, you might still continue facing the error. Apart from this validation rule, there are other validation rules as well which can be the probable cause of the error. So make sure you check them before hand.
While working in MS Access, a variety of errors can crop up. In case you encounter data errors, immediately take recourse to an Access recovery utility to deal with them.
