AutoIncrement Property

  • Статия

Version: Available or changed with runtime version 1.0.

Sets whether the field value should be automatically incremented.

Applies to

  • Table field

The fields must be of Integer Data Type and BigInteger Data Type.

Property Value

True if the field value is automatically incremented; otherwise, false. The default value is false.

Note

If you want to manually assign a value to a field that has the AutoIncrement property set to true, you must be member of the SQL Server db_owner database permission set.

Syntax

field(4; D; Integer) { AutoIncrement = true; }

Remarks

A table can only contain one auto-increment field. The numbers assigned to this field will not always be consecutive for the following reasons:

  • If you delete some records from a table, the numbers used for these records are not reused.

  • If several transactions are performed at the same time, they will each be assigned a different number. However, if one of these transactions is rolled back, the number that it was assigned is not reused.

If you add an auto-increment field to an existing table, the field automatically generates consecutive values and inserts them into the table. If you enable the AutoIncrement property for a field that already contains data, there must be no zero values in the field.

The AutoIncrement property is designed to always assign numbers automatically. If you want to insert a record, be sure that the value in this field is blank before you insert the record.

The AutoIncrement property does not work with Dynamics 365 Business Central temporary tables.
