Columns
Column | Type | Size | Nulls | Auto | Default | Children | Parents | Comments | |||
---|---|---|---|---|---|---|---|---|---|---|---|
id | uuid | 2147483647 | uuid_generate_v7() |
|
|
The record’s primary key. The definitive identifier of the record in the system. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
access_account_id | uuid | 2147483647 | null |
|
|
The access account which is being granted authentication rights to the given instance. |
|||||
instance_id | uuid | 2147483647 | null |
|
|
The identity of the instance to which authentication rights is being granted. |
|||||
access_granted | timestamptz | 35,6 | √ | null |
|
|
The timestamp at which access to the instance was granted and active. General Usage If the access did not require the access invitation process, this value will typically reflect the creation timestamp of the record. If the invitation was required, it will reflect the time when the access account holder actually accepted the invitation to access the instance. |
||||
invitation_issued | timestamptz | 35,6 | √ | null |
|
|
When inviting unowned, independent access accounts such as might be used by an external bookkeeper, the grant of access by the instance owner is not immediately effective but must also be approved by the access account holder being granted access. General Usage The timestamp in this column indicates when the invitation to connect to the instance was issued. If the value in this column is null, the assumption is that no invitation was required to grant the access to the access account. |
||||
invitation_expires | timestamptz | 35,6 | √ | null |
|
|
The timestamp at which the invitation to access a given instance expires. |
||||
invitation_declined | timestamptz | 35,6 | √ | null |
|
|
The timestamp at which the access account holder explicitly declined the invitation to access the given instance. |
||||
diag_timestamp_created | timestamptz | 35,6 | now() |
|
|
The database server date/time when the transaction which created the record started. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
diag_role_created | text | 2147483647 | null |
|
|
The database role which created the record. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
diag_timestamp_modified | timestamptz | 35,6 | now() |
|
|
The database server date/time when the transaction which modified the record started. This field will be the same as diag_timestamp_created for inserted records. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
diag_wallclock_modified | timestamptz | 35,6 | clock_timestamp() |
|
|
The database server date/time at the moment the record was actually modified. For long running transactions this time may be significantly later than the value of diag_timestamp_modified. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
diag_role_modified | text | 2147483647 | null |
|
|
The database role which modified the record. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
diag_row_version | int8 | 19 | 1 |
|
|
The current version of the row. The value here indicates how many actual data changes have been made to the row. If an update of the row leaves all data fields the same, disregarding the updates to the diag_* columns, the row version is not updated, nor are any updates made to the other diag_* columns other than diag_update_count. General Usage This column is system maintained and should be considered read only in normal operations. Direct Usage This column is frequently used by by application logic to resolve the “dirty write” issues which can arise from concurrent data changes. As such any administrative override of automatic system maintenance of this value should consider the ramifications on application function. |
|||||
diag_update_count | int8 | 19 | 0 |
|
|
Records the number of times the record has been updated regardless as to if the update actually changed any data. In this way needless or redundant record updates can be found. This row starts at 0 and therefore may be the same as the diag_row_version - 1. General Usage This column is system maintained and should be considered read only in normal operations. |
