CreateTable Logical Operator¶

CreateTable is a LogicalPlan.

Analysis Phase¶

CreateTable can never be resolved and is replaced with (resolved to) a logical command at analysis phase in the following rules:

• (for non-hive data source tables) DataSourceAnalysis posthoc logical resolution rule to a CreateDataSourceTableCommand or a CreateDataSourceTableAsSelectCommand logical command (based on the query defined or not, respectively)

• (for hive tables) HiveAnalysis post-hoc logical resolution rule to a CreateTableCommand or a CreateHiveTableAsSelectCommand logical command (based on the query defined or not, respectively)

Creating Instance¶

CreateTable takes the following to be created:

• CatalogTable
• SaveMode
• Optional Query (LogicalPlan)

While being created, CreateTable asserts the following:

• The table to be created must have the provider
• With no query, the SaveMode must be either ErrorIfExists or Ignore

CreateTable is created when:

• DataFrameWriter.saveAsTable operator is used (and creates a table)
• ResolveSessionCatalog logical resolution rule is executed (to constructV1TableCmd)

Never Resolved¶

resolved: Boolean

resolved is always false.
