How to fix Error 3705 on Windows Server 2025 / Windows 11

Troubleshooting Guide: SQL Server Error 3705

Why This Error Happens

Error 3705 occurs when a DROP statement is executed against an object using the wrong object-type keyword—for example, attempting to run DROP TABLE on an object that is actually a VIEW, or DROP PROCEDURE on an object that is actually a FUNCTION. SQL Server’s metadata engine validates the object type stored in sys.objects against the keyword used in the DROP statement, and a mismatch triggers this error before any schema modification occurs. This is typically caused by schema drift, incorrect deployment scripts, or confusion between similarly named objects created by different teams or automated CI/CD pipelines.

Step-by-Step Resolution Guide

Step 1: Identify the Actual Object Type

  • Open SQL Server Management Studio (SSMS) or Azure Data Studio connected to the affected instance on Windows Server 2025 / Windows 11.
  • Run the following query to confirm the real type of the object referenced in the error message:
  SELECT name, type, type_desc 
  FROM sys.objects 
  WHERE name = 'YourObjectName';
  • Cross-reference type_desc (e.g., VIEW, SQL_STORED_PROCEDURE, SQL_SCALAR_FUNCTION) with the keyword used in your original DROP statement.

Step 2: Correct the DROP Statement Syntax

  • Replace the incorrect keyword with the one matching the type_desc output from Step 1.
  • Common corrections:
  • Use DROP VIEW instead of DROP TABLE for views.
  • Use DROP FUNCTION instead of DROP PROCEDURE for scalar or table-valued functions.
  • Use DROP PROCEDURE instead of DROP FUNCTION for stored procedures.
  • Re-run the corrected statement in a new query window to confirm it executes without error.

Step 3: Audit and Fix Deployment/Migration Scripts

  • Search your source-controlled .sql deployment scripts (e.g., in DevOps repos or SSDT projects) for the offending DROP statement using a text search tool like grep or VS Code’s “Find in Files.”
  • Update the script to use the correct object-type keyword, and add a pre-check using OBJECTPROPERTY() to future-proof the script:
  IF OBJECTPROPERTY(OBJECT_ID('YourObjectName'), 'IsView') = 1
      DROP VIEW YourObjectName;
  • Commit and redeploy the corrected script through your standard CI/CD pipeline.

Step 4: Check for Naming Collisions Across Schemas

  • Verify there isn’t a duplicate object name across different schemas (e.g., dbo.MyObject vs sales.MyObject) causing confusion in the script.
  • Run:
  SELECT s.name AS SchemaName, o.name, o.type_desc
  FROM sys.objects o
  JOIN sys.schemas s ON o.schema_id = s.schema_id
  WHERE o.name = 'YourObjectName';
  • Fully qualify the object name with its schema in the corrected DROP statement to avoid ambiguity.

Alternative or Verification Steps

  • Verify the fix by re-running the corrected DROP statement in a test/staging environment first; confirm no Error 3705 is returned and the object is removed from sys.objects.
  • If the error persists, check for synonyms (sys.synonyms) pointing to the object under a different name, as DROP statements cannot target a synonym’s underlying object type directly—drop the synonym separately using DROP SYNONYM.
