FIX: Access violation occurs when MSTVF references an In-Memory OLTP large-value data type with interleaved execution enabled in SQL Server 2019

Applies to: SQL Server 2019 on Windows


Consider the following scenario:
  • You have Cumulative Update 2 for SQL Server 2019 or later installed. 
  • There is a multi-statement table valued function (MSTVF) that references large-value data type columns from an In-Memory OLTP table.
  • The MSTVF is queried in the context of database compatibility level 140 or higher.
  • The database scoped configuration INTERLEAVED_EXECUTION_TVF is ON and the query is not using the DISABLE_INTERLEAVED_EXECUTION_TVF query hint.
In this scenario, an access violation occurs, and you mayreceive an error message that resembles the following:

SQL query fails with fatal error.
Msg 233, Level 20, State 0, Line LineNumber
A transport-level error has occurred when receiving resultsfrom the server.

Additionally, an error message is logged in the SQL Servererror log.
