KB4053291 - FIX: "sys.dm_exec_query_profiles" DMV returns wrong "estimate_row_count" in SQL Server 2017 on Linux and Windows

Symptoms

When you query the SYS.DM_EXEC_QUERY_PROFILES DMV to examine an execution plan that references tables that contain many rows (more than 2³²), the DMV may return an incorrect number of rows in the “estimate_row_count” column of some operators, capping the value at 2³².

Note Neither the estimated query plan or live query statistics are affected by this issue.

Cause

This issue occurs because the “estimate_row_count” column is internally handled as a 32-bit value. For values greater than 2³², Microsoft SQL Server limits the column to 2³².

Resolution

This fix is included in Cumulative Update 2 for SQL Server 2017.
