IdentityIncrement Property
Esta característica se quitará en una versión futura de Microsoft SQL Server. Evite utilizar esta característica en nuevos trabajos de desarrollo y tenga previsto modificar las aplicaciones que actualmente la utilizan.
The IdentityIncrement property exposes the value that Microsoft SQL Server adds to the maximum existing row identity value as it generates the next identity value.
Sintaxis
object.IdentityIncrement [=value]
Parts
object
An expression that evaluates to an object in the Applies To listvalue
A long integer greater than or equal to 1
Data Type
Long
Modifiable
Read/write prior to SQL Server column creation. Read-only for existing columns.
Prototype (C/C++)
HRESULT GetIdentityIncrement(LPLONG pRetVal);
HRESULT SetIdentityIncrement(LONG NewValue);
Notas
SQL Server allows the row identity property on a single column within a table. Identity, like a primary key, identifies a row uniquely. SQL Server implements row identification using a numeric value. As rows are inserted, SQL Server generates the row value for an identity column by adding an increment to the existing maximum value.
For example, the identity values for the first three rows inserted into a table containing a column defined with row identity, an identity seed of 1, and an increment value of 3, are 1, 4, and 7.
