S,F,I numbers as related to business table

LorindaGilbert — Fri, 12 Jan 2024 21:24:56 GMT

Hi All,

I need to check some indices on some tables in SQL server SDE. I have the S number for the table that needs to be reindexed, however, I can't find the magic decoder ring for determining the business table name in order to perform the reindex.

I know that the table number in the sde.table_registry gives me the adds and deletes tables, but my experience in the past was that the s, f, and i table numbers weren't the same as the adds and deletes.

Can someone point me in the right direction?

Thanks a bunch!

Lorinda

To find the Delta Tables and the "i" table we use the registration_id in the sde.table_registry.
To find the S tables we use the layer_id in the sde.layers table.

A few things to mention.

B table - base table

F table - features table - store the geometries (shape).

the new versions of the geodatabase do not have a F table anymore

the shape column is now stored in the base table

A table - adds table - traditional versioning

D table - deletes table - traditional versioning

S table - spatial index table

There is no esri st_geometry spatial type in SQL Server. We use the native SQL Server Geometry & Geography Spatial Types with the Geodatabase.

SQL Server Geodatabases with the Geometry spatial type you will find an "i" table but there is no "S" spatial index table.

The SQL Server Geodatabase Featureclass has a Base Table, "i" table, Delta Tables (traditional versioning) - A - Adds, D - Deletes, if geodatabase archiving is enabled then there will be another table with the name <base table name>_H.

"i" table is used to store the increment for the ObjectID, this was done before SQL Server had sequences.

Oracle esri st_geometry spatial type you will find an S table. Hence the Oracle Geodatabase featureclass has a Base Table, Delta Tables (traditional versioning) - A - Adds, D - Deletes, and the S - spatial index table, if geodatabase archiving is enabled then there will be another table with the name <base table name>_H. The H is for History. There is no "i" table.

Oracle Geodatabase does not have "i" table because in Oracle we use sequences for the ObjectID.

Oracle Geodatabases also support the native Oracle SDO Spatial datatype.

PostgreSQL Geodatabases has the esri st_geometry spatial type as well and it also supports the PostGIS Spatial Type.

To find the business table name associated with the S number in SQL Server SDE, you can check the SDE.TABLE_REGISTRY. While the S, F, and I table numbers might not directly correspond to adds and deletes, the SDE.TABLE_REGISTRY should contain information about the relationships between these tables.
You can query the SDE.TABLE_REGISTRY using the S number to find the associated business table name. Here's an example query:
sqlCopy code
SELECT TABLE_NAME FROM SDE.TABLE_REGISTRY WHERE REGISTRATION_ID = 'YourSNumber';
 
Replace 'YourSNumber' with the actual S number you have. This should provide you with the business table name associated with the given S number, helping you perform the reindex on the correct table.
Best of luck!

In the context of ArcSDE (Spatial Database Engine), S, F, and I numbers are identifiers associated with different types of tables:

S Number: Represents the state tables, storing the current state of spatial data.
F Number: Signifies the adds and deletes tables, keeping track of changes made to the spatial data.
I Number: Corresponds to the spatial index tables, which optimize spatial queries for faster retrieval.

These numbers are crucial in managing spatial data within the geodatabase, allowing for efficient tracking of changes and optimization of spatial queries. The relationship to a business table is established through the Registration_ID in the SDE.TABLE_REGISTRY, connecting the S, F, and I tables to their associated business table.
