How to Fix: SQL Update with row_number()
Direct conversational advice for SQL Update with row_number().
📋 Table of Contents
The issue in your SQL query is due to the way you are using parentheses. The subquery inside the update statement should be wrapped in a SELECT statement, not just a regular UPDATE statement.
🛑 Root Causes of the Error
- The parentheses in your query are causing a syntax error, preventing the subquery from being executed.
🚀 How to Resolve This Issue
Method 1: Subquery with SELECT statement
- Step 1: Replace the UPDATE statement with a SELECT statement, wrapping the subquery in parentheses.
Method 2: Using a Common Table Expression (CTE)
- Step 1: Create a CTE to wrap the subquery, and then use it in the UPDATE statement.
✨ Wrapping Up
By applying these methods, you should be able to update your CODE_DEST column with an incremental number using the ROW_NUMBER() function.
