Bug Reference KB article number Description Fix area Platform
13464184   SQL Server may block renaming a database when the database consists of one or more external data pool tables. If you attempt to rename the database in the scenario, you may get the following error:
Alter database name is not supported in Big Data Cluster if the database contains external data pool tables. Drop the external data pool tables to perform the operation.
13526183 4538581 FIX: Scalar UDF Inlining issues in SQL Server 2019 SQL Engine All

When shrinking a database, you may receive a database consistency error if the shrinking process encounters an IAM page that is the first and only IAM page. The symptoms may include assertions errors involving heapdataset. Confirm that you do not have any inconsistencies by executing DBCC CHECKDB after shrink operations. Applying this update will prevent future occurrence of this issue and not clean up past inconsistencies. SQL Engine All
13491460   When PolyBase queries are cancelled shortly after being scheduled, the cancellation may timeout after one hour (and fail to cancel the execution) and generate a dump of Data Movement service. SQL Engine All

13440400   When using INSERT INTO … VALUES (…) or INSERT INTO SELECT… statement to populate Data Pool external table and if user specifies the target table columns, the list of target table column names must have the same order as the source table columns and must be the full list. Starting this cumulative update, you will get detailed new errors outlining these conditions:
"Source column count must match the # of columns in the destination table"
"Order of source columns must match the order of columns in the destination table"
SQL Engine All
13485259   Encrypt keyword is missing from externalaccessconfig in SQL Server 2019 SQL Engine All
13530274   When you deploy SQL Server Big Data Clusters in Active Directory mode, SQL Server uses domain DNS name to create user in sql server. When the DNS name and realm name are different, failures may occur. After installing this update, SQL Server will use realm name to create user in sql server. SQL Engine All
13464137   When you use Accelerated Database Recovery feature on a database in SQL Server 2019, which is part of an Availability Group or Transactional Replication, an assertion error occurs.

SQL Engine Windows
13491012   Msg 3628 (The Database Engine may receive a floating point exception from the operating system while processing a user request) may occur during a clustered columnstore index rebuild. SQL Engine Windows
13526506   When a Windows principal that is not mapped to a specific database user accesses a database by using membership in a windows group or AAD group, a user id of 0 may be assigned to the user. When the user tries to use libraries that are installed by other dbo/sysadmin user, the user may not see any external libraries. After applying this update, a user id of 0 would have access to external libraries installed by the dbo (libraries in public scope). Since there is no database user that is mapped to the Windows principal, the user with user id 0 cannot create or install external libraries. SQL Engine Windows
13525965   You can access configurations that ship with PolyBase when specifying a DSN in the CONNECTION_OPTIONS of a Generic ODBC External Data Source definition. The options are picked up by matching the driver name used in the DSN definition. This currently applies to the following drivers:

13458643   Spatial data types (Geometry and Geography) are implemented as CLR data types in SQL Server. When the application domain hosting the spatial data type structures is unloaded, the engine treats this as a schema change to the underlying objects referenced in the cursor. As a result, spatial query may fail with related error message when the schema change is detected. SQL Engine Windows
13464812   Access violation may occur when a cursor is used to retrieve data from scalar UDF and the underlying table contains primary key. SQL Engine Windows
13443318   When you have external tables on a database in SQL Server 2019 and try to publish different tables from the same database, you may receive the following error message in SSMS:
