Description

Hi,

I am trying to change datatype for two columns at a time, but receiving error stating - Incorrect syntax near ','. Syntax is given below.

Alter Table Trail14
Alter Column ID Int,
Alter column Weight Decimal;

Please let me know can Datatype, or alter column or constraint can be changed for multiple columns at a time?

First steps

  1. Read the whole issue, then the project's contributing guide.

Research direction

The issue names only the SQL statement for Trail14 and does not identify a repository file, test, or entry point. Start by reviewing the reported ALTER TABLE syntax in the context of SQL Server samples and determine whether this repository contains a relevant sample to update. Done means the supported multi-column datatype or constraint guidance is clear and verified against the appropriate SQL Server behavior.
