Troubleshooting Guide: SQL Server Error 1092

Why This Error Happens

This error occurs when a T-SQL statement—most commonly UPDATE STATISTICS or an index/statistics maintenance command—is passed more statistics names than the specified option supports. Certain options (such as those expecting a single column or a single statistics object) are hard-coded to accept only one identifier, and supplying multiple comma-separated names violates that syntax constraint. This is typically a query authoring issue rather than a server configuration problem, but it can also surface from outdated maintenance scripts, third-party tools, or ORM-generated statements that were not updated for SQL Server 2025 syntax changes.

Step-by-Step Resolution Guide

Step 1: Identify the Offending Statement

  • Check the SQL Server error log at C:\Program Files\Microsoft SQL Server\MSSQL17.MSSQLSERVER\MSSQL\Log\ERRORLOG for the exact query batch tied to Error 1092.
  • Use SQL Server Profiler or Extended Events (sqlserver.error_reported) to capture the precise statement and session that triggered the error.
  • Note the %ls option name reported in the error text—this tells you which clause is misconfigured.

Step 2: Correct the Statistics Name List in the Query

  • Open the script in SQL Server Management Studio (SSMS) and locate the UPDATE STATISTICS, CREATE STATISTICS, or DROP STATISTICS command.
  • Ensure options like WITH FULLSCAN, WITH RESAMPLE, or WITH SAMPLE are not being passed multiple statistics names if the option restricts input to one.
  • Split the command into separate statements, one per statistics name, for example:
  UPDATE STATISTICS dbo.SalesOrder (IX_Stat1);
  UPDATE STATISTICS dbo.SalesOrder (IX_Stat2);
  • Avoid comma-separating names where the specific option clause only accepts a single value.

Step 3: Audit and Update Maintenance Scripts/Jobs

  • Review SQL Server Agent jobs under SQL Server Agent > Jobs in SSMS for legacy statistics maintenance scripts (e.g., Ola Hallengren’s IndexOptimize or custom scripts).
  • Update any script referencing deprecated multi-name syntax to match SQL Server 2025’s stricter parsing rules.
  • Redeploy the corrected script and re-run the job manually to confirm the error no longer appears in the job history.

Step 4: Validate Application/ORM-Generated Queries

  • If the error originates from an application (e.g., Entity Framework, a reporting tool), check the generated SQL via SQL Server Profiler.
  • Update the application’s data access layer or stored procedure to generate one statistics name per statement.
  • Redeploy the updated application build to Windows Server 2025/Windows 11 client machines.

Alternative or Verification Steps

  • Re-run the corrected statement directly in SSMS against a test database and confirm it completes without Error 1092 in the Messages tab.
  • Check sys.stats and sys.dm_db_stats_properties to confirm the statistics object was updated/created successfully as expected.
