Why does Microsoft access auto number keep resetting by itself?
When you use the compact and repair tool, the Auto Number in a table will be reset to one greater than the largest existing AutoNumber value. For example, consider a table with an AutoNumber field that has 10 rows with autonumbered values from 1 to 10. If you delete rows 6, 9, and 10, and then compact and repair the database, the AutoNumber seed will be reset to 9 (1 greater than the maximum AutoNumber value in the table, which in this example is 8). If the table has no data in it, the AutoNumber will be reset to 1.
What a pre-filled user field called in access?
It is a field with a default value, so it is a default value field. Autonumber fields can also put values in themselves, as can calculated fields.
How do you insert a record into the table which has an identity column?
In Microsoft Access you can insert a record directly via the table object, execute an append query, enter a record into a data bound form or write a record programatically via the recordset object. In Access an identity column is referred to as a Primary Key. If the Primary Key column's data type is set to autonumber then the column is read only and will automatically be assigned the next unique number (datatype long) within that table. If the Primary Key column's data type is NOT set to autonumber then you must provide a unique, non-null value when adding the record. Append Query on a table with an autonumber Primary Key: Insert into tbl_Test (Test_FirstName, Test_LastName) Values ('George', 'Washington') Append Query on a table with an non-autonumber Primary Key: Insert into tbl_Test (Test_Id, Test_FirstName, Test_LastName) Values (1,"George","Washington")
Is it true or false that certain Access data type have a predefined field size that cannot be changed?
The Field Size Property defines a field values maximum storage size for Text, Number, and AutoNumber fields only. The other data types have no Field Size property because their storage size is either a fixed, predetermined amount or is determined automatically by the field value itself.TRUE
