How to fix Error 10057 on Windows Server 2025 / Windows 11

by

Why This Error Happens

Error 10057 occurs when a rowset—typically tied to an OLE DB provider, cursor, or in-memory table operation—reaches the maximum number of active rows it is architecturally permitted to hold. This is commonly triggered by exceeding the hard limit on rows within a single cursor-based result set, an undersized or misconfigured memory-optimized table in SQL Server 2025, or fragmented/corrupted index structures that force the rowset manager to miscalculate active row counts. It can also surface when third-party or legacy OLE DB drivers interacting with SQL Server impose their own row ceiling well below SQL Server’s actual capacity.

Step-by-Step Resolution Guide

Step 1: Identify the Query or Process Triggering the Limit

  • Check SQL Server Error Logs located at C:\Program Files\Microsoft SQL Server\MSSQL17.MSSQLSERVER\MSSQL\Log\ERRORLOG for the exact query context.
  • Run sp_who2 or query sys.dm_exec_requests to identify the active session generating Error 10057.
  • Note whether the operation uses a server-side cursor, bulk insert, or memory-optimized table.

Step 2: Switch from Cursor-Based Operations to Set-Based Logic

  • Replace FAST_FORWARD or KEYSET cursors with standard SELECT/INSERT set-based statements where possible.
  • If using SSIS or a legacy OLE DB provider, update the connection manager to use the native MSOLEDBSQL 19+ driver instead of outdated drivers.
  • Adjust application code to avoid opening cursors against tables with extremely high row counts (typically above 2^31 rows in older rowset implementations).

Step 3: Rebuild Indexes and Validate Table Integrity

  • Open SQL Server Management Studio (SSMS) and run:
  DBCC CHECKTABLE ('YourTableName') WITH ALL_ERRORMSGS;
  • If corruption is found, rebuild the clustered index:
  ALTER INDEX ALL ON YourTableName REBUILD;
  • Confirm statistics are current with UPDATE STATISTICS YourTableName WITH FULLSCAN;.

Step 4: Review Memory-Optimized Table Configuration (If Applicable)

  • Navigate to SSMS > Databases > YourDatabase > Tables and check if the affected table uses MEMORY_OPTIMIZED = ON.
  • Verify the database has sufficient space allocated in the FILESTREAM/memory-optimized filegroup via Database Properties > Filegroups.
  • Increase allocated container size in C:\SQLData\MemoryOptimizedFG if space constraints are causing row ceiling miscalculations.

Step 5: Apply the Latest SQL Server 2025 Cumulative Update

  • Go to Microsoft Update Catalog and download the latest Cumulative Update (CU) for SQL Server 2025.
  • Install via elevated PowerShell:
  Setup.exe /Action=Patch /IAcceptSQLServerLicenseTerms /Quiet
  • Restart the SQL Server service through Services.msc (SQL Server (MSSQLSERVER)) after installation.

Alternative or Verification Steps

  • Re-run the original query or application process that triggered Error 10057 and confirm the row insertion completes without exception.
  • If the error persists, isolate the table into a new test database using BCP export/import to rule out underlying corruption versus a genuine row-count architectural limit.
