update statistics

If the table on which the statistics are requested has no indexes, Component Integration Services issues the following command:
```
select count(*) from table_name 
```
It is also the only command issued when trace flag 11209 is on.

If the table has an index and the index is specified in the command, Component Integration Services issues the following commands:

select count(*) from table_name

select count(*) column_name [,column_name, ...]
 from table_name 
 group by column_name [,column_name, ..]

The column name(s) represent the column or columns that make up the index.

For example, when the following command is issued:

update statistics customers ind_name

Component Integration Services issues:

select count(*) from customers

select count(*) last_name, first_name 
 from customers
 group by last_name, first_name

If the table has one or more indexes but no index is specified in the statement, Component Integration Services issues the select count (*) once, and the select/order by commands for each index.
You must have the sa_role to run update statistic on a proxy table using a remote login.
In Adaptive Server version 15.0 or later, if a proxy table points to a partitioned table, only global statistics are imported. These are aggregated statistics since proxy tables in Adaptive Server version 15.0 are not partitioned.

The processing of update statistics in this server class is identical to pre-Adaptive Server version 15.0 servers.

The processing of update statistics in this server class is identical to that of server class ASEnterprise described above.
If the direct_connect indicates that is cannot handle the group by or the count(*) syntax, statistics are not collected for the direct_connect.
