Create or Alter table

The Create or alter table creates table if it doesn’t exist, or alters it according to the table definition.

Create or Alter Node properties

Create Or Alter has two configuration groups:

• Node Properties
• Create table Options
• Insert data Options

Limitations of Create or Alter Table

• Collation specifications cannot be altered.

• New columns can only be added to the end of the column list
• Columns cannot be renamed. If you attempt to rename a column, the column is dropped and a new column is added.WHen you rename a column in Coalesce mapping grid.Ensure to move the same to the end of column list in mapping grid.

Create Or Alter Table Deployment

Create Or Alter Table Initial Deployment

When deployed for the first time into an environment the Create or Alter table node of materialization type table or transient table will execute the below stage:

Stage	Description
Create/Alter table/transient table	This will execute a CREATE OR ALTER statement and create a table in the target environment

Create Or Alter Table Redeployment

Altering the Tables and Transient Tables

When redeployed with change in target location or change in node name,results in alter of the table

Stage	Description
Rename/Move Table	Alter table statement is executed to perform the alter operation

Changing Materialization Type

Change	Stages Executed

When the Create or Alter table node is redeployed with any changes in table or config changes result in re-creating table

Stage	Description
Create/Alter table/transient table	This will execute a CREATE OR ALTER statement and create a table in the target environment

Redeployment with no changes

If the nodes are redeployed with no changes compared to previous deployment,then no stages are executed

Create Or Alter Tables Undeployment

If a Create or Alter table node of materialization type table/transient table are deleted from a Workspace, that Workspace is committed to Git and that commit deployed to a higher level environment then the table in the target environment will be dropped.

This is executed in below stage:

Stage	Description
Drop table/transient table	Removes the table from the environment

Create or alter view

A create or alter view node creates a new view if it doesn’t already exist, or updates the properties of an existing view to match those defined in the statement.
