Troubleshooting Guide: Error 2750 in Microsoft SQL Server 2025

Why This Error Happens

Error 2750 occurs when a column, variable, or parameter is defined with a numeric precision (for decimal or numeric data types) that exceeds SQL Server’s maximum supported precision of 38 digits. This typically results from manually scripted DDL statements, migrated code from another database platform (such as Oracle, which supports higher precision), or a misconfigured ORM/schema generation tool that calculated an invalid precision value. In rare cases, corrupted or malformed migration scripts imported into SQL Server Management Studio (SSMS) can also pass precision values that were never validated before execution.

Step-by-Step Resolution Guide

Step 1: Identify the Offending Object

  • Open the exact T-SQL script that triggered the error in SSMS or Azure Data Studio.
  • Locate the column or parameter number referenced in the error message (#%d).
  • Check the data type definition for DECIMAL(p, s) or NUMERIC(p, s) where p (precision) exceeds 38.

Step 2: Correct the Precision Definition

  • Edit the CREATE TABLE, ALTER TABLE, or CREATE PROCEDURE statement to set precision to 38 or lower.
  • Example fix: Change DECIMAL(50, 10) to DECIMAL(38, 10).
  • If migrating from another RDBMS (e.g., Oracle NUMBER(40)), manually cap all converted columns at DECIMAL(38, x).
  • Re-run the script using sqlcmd -S <ServerName> -i fixed_script.sql or execute directly in SSMS.

Step 3: Audit Migration and ORM Scripts

  • If using SQL Server Migration Assistant (SSMA) or an ORM (Entity Framework, Hibernate), review the schema mapping configuration file.
  • Update the mapping rules so source precision values are automatically clamped to 38 before generating SQL Server DDL.
  • Re-generate and re-deploy the schema script.

Step 4: Validate Application and Stored Procedure Parameters

  • Inspect stored procedures, functions, and table-valued parameters for @Parameter DECIMAL(p,s) declarations.
  • Correct any parameter exceeding the 38-digit limit.
  • Deploy the updated object using ALTER PROCEDURE or ALTER FUNCTION.

Alternative or Verification Steps

  • Run SELECT name, precision, scale FROM sys.columns WHERE precision > 38; against the target database to confirm no remaining invalid definitions exist.
  • If the error persists in a third-party application, check for a newer driver or application patch that addresses precision mapping, since the issue may originate from the client-side schema generation layer rather than the raw T-SQL script.
