[ISSUE] Issue with databricks_sql_table resource

[ian-norris-ncino]

Configuration

resource "databricks_sql_table" "example_table" {
  name         = local.example_table_name
  catalog_name = var.example_catalog.name
  schema_name  = example_catalog.example_schema.name
  table_type   = "MANAGED"
  warehouse_id = data.databricks_sql_warehouse.warehouse.id
  comment      = "Example resource"
  owner        = var.resource_owner_name

  properties = {
    "delta.feature.allowColumnDefaults" = "supported"
  }

  column {
    name     = "column_a"
    type     = "STRING"
    comment  = ""
    nullable = false
  }
  column {
    name     = "column_b"
    type     = "TIMESTAMP DEFAULT current_timestamp()"
    comment  = ""
    nullable = false
  }
}

Expected Behavior

When I apply the first time the table is created successfully. When I plan/apply a second time with the same configuration no changes should be detected.

Actual Behavior

When I apply the first time the table is created successfully. However, a follow up plan/apply will yield the error changing the 'type' of an existing column is not supported.

Steps to Reproduce

terraform version
Terraform v1.10.4
on darwin_arm64
+ provider registry.terraform.io/databricks/databricks v1.63.0

Is it a regression?

Nope
