Create Index

Create Index

The Create Index command creates an index on an archived table. The Data Vault creates one index file for each data file for which the table has a registration.
You can create an index for a table any time after you archive data to the Data Vault. For example, you archive data to the Data Vault. You identify frequently used queries that have significant performance delays. You create indexes for the tables.
The
ssasql
Create Index command uses the following syntax:
create index on <schema name>.<table name> (column name);
The following table describes the
ssasql
Create Index arguments:
Argument
Description
schema name
Required. Name of the schema that includes the table columns you want to index.
table name
Required. Name of the table that includes the columns you want to index.
(column name)
Required. Name of the columns on which you want to create an index. You can create the index on one or more columns in the table. The maximum number of columns is the maximum amount of columns in the table.
Use a comma to separate multiple columns.
To create indexes on multiple tables, run the command separately for each table. If you create an index for a table that already has an index, the command fails.
After you create an index, you must renew the index if you archive more data to the table. You must drop and create an index if you repartition the table.
