Ejemplo de índice en teradata
Descripción de la copia de índices de hash y de unión entre versiones de Teradata Database, incluyendo un ejemplo y una lista de parámetros. Modelo de Bases de Datos Teradata. Ejemplo de EXPLAIN con un simple " Join Index". CREATE Teradata sólo requiere un índice primario para cada tabla. The next example creates a unique secondary index(USI). CREATE UNIQUE INDEX (department) ON tbl_employee; The following example creates the Salary table with column EmployeeNo as Unique Primary Index. CREATE SET TABLE Salary ( EmployeeNo INTEGER, Gross The purpose of the COLLECT STATISTICS command is to gather and store demographic data for one or more columns or indices of a table or join index. This Teradata data dictionary tables are metadata tables in the DBC database. Dbc. Indices : Stores all the index related informatiom for tables, views, join index

Indices : Stores all the index related informatiom for tables, views, join index In Teradata, we can create several kinds of Tables ; one of them is VOLATILE Tables. Volatile tables are used to store some data which is session specific and An index is always associated with a table (or with multiple tables in case of the Join index), never with a view. But: the execution plan of a
