ApplyDefaultCollationToStringType

object ApplyDefaultCollationToStringType extends Rule[LogicalPlan]

Resolves string types in logical plans by assigning them the appropriate collation. The collation is inherited from the relevant object in the hierarchy (e.g., table/view -> schema -> catalog). This rule is primarily applied to DDL commands, but it can also be triggered in other scenarios. For example, when querying a view, its query is re-resolved each time, and that query can take various forms.

  43. def resolveDefaultCollation(plan: LogicalPlan): LogicalPlan

    Determines the default collation for an object in the following order: 1.

    Determines the default collation for an object in the following order: 1. Use the object's explicitly defined default collation, if available. 2. Otherwise, use the default collation defined by the object's schema. 3. If not defined in the schema, use the default collation from the object's catalog.

    If none of these collations are specified, None will be persisted as the default collation, which means the system default collation UTF8_BINARY will be used and the plan will not be changed. This function applies to DDL commands. An object's default collation is persisted at the moment of its creation, and altering the schema or catalog collation will not affect existing objects.
