copyTable
abstract fun copyTable(columnNameMapping: ColumnNameMapping, sourceTableName: TableName, targetTableName: TableName): Sql
Copy all records from sourceTable to targetTable. May assume that both tables exist, and have schemas which match the expected schema, i.e. io.airbyte.cdk.load.component.TableSchemaEvolutionClient.ensureSchemaMatches was invoked on both tables.
MUST NOT assume that the columns are in the same order in both tables.
