Setting and Showing the Current Schema

By default, the schema of the session is USR. The SQL statement, SET SCHEMA, allows you to set the schema for the Neoview Script session. For example, this SET SCHEMA statement changes the default schema to PERSNL for the session:

SQL>set schema persnl;

--- SQL operation complete.

SQL>delete from employee +>where first_name='TIM' and +>last_name='WALKER';

--- 1 row(s) deleted.

SQL>

The schema that you specify with SET SCHEMA remains in effect until the end of the session or until you execute another SET SCHEMA statement.

If you execute this statement in a script file, it affects not only the SQL statements in the script file but all subsequent SQL statements that are run in the current session. If you set the schema in a script file, reset the default schema for the session at the end of the script file.

For more information about the SET SCHEMA statement, see the Neoview SQL Reference Manual.

The SHOW SCHEMA command displays the current schema for the session. For example, this SHOW SCHEMA command displays SCHEMA PERSNL, where PERSNL is the name of the current schema for the session:

SQL>show schema

SCHEMA PERSNL

SQL>

For more information, see the “SHOW SCHEMA Command” (page 120).

Limiting the Result Set of a Query

To set the maximum number of rows to be returned by SELECT statements that are executed in the session, enter the SET LIST_COUNT command. For example, this SET LIST_COUNT command limits the result set of queries to 20 rows:

SQL>set list_count 20

To show the limit that is in effect for the session, enter the SHOW LIST_COUNT command. For example, this SHOW LIST_COUNT command shows that the number of rows returned by SELECT statements is unlimited:

SQL>show list_count

LISTCOUNT 0 [All Rows]

For more information, see the “SET LIST_COUNT Command” (page 106) and the “SHOW LIST_COUNT Command” (page 115).
