PROPERTIES clauseA PROPERTIES clause, or list of properties, is an optional part of an SQL-J CREATE TABLE statement, CREATE INDEX statement, CONSTRAINT clause, FROM clause, TableExpression, or INSERT statement. Properties specified in a PROPERTIES clause fall into one of the following categories: SyntaxThe basic syntax of a PROPERTIES clause is as follows: NOTE: If you specify the same property multiple times within a PROPERTIES clause, an exception is thrown. Storage-Related PropertiesFor CREATE TABLE, CREATE INDEX, and CONSTRAINT, a PROPERTIES clause allows you to specify storage properties for the table or index being created and overrides the properties currently set on a database-wide or system-wide basis. These properties include:
For indexes, you can set only cloudscape.storage.initialPages and cloudscape.storage.pageSize. For tables, you can set cloudscape.storage.initialPages, cloudscape.storage.minimumRecordSize, cloudscape.storage.pageSize, or cloudscape.storage.pageReservedSpace. Any mistyped or unused properties are ignored. For more information, see Conglomerate-Specific Properties in Tuning Cloudscape.
To verify properties used for a specific table or index, use the static methods of COM.cloudscape.database.PropertyInfo (aliased as PropertyInfo). For more information, see Verifying Conglomerate-Specific Properties in the Cloudscape Developers Guide. Optimizer Override PropertiesFor a PROPERTIES clause in a FROM clause, you can specify: For a PROPERTIES clause in a TableExpression, you can specify for a specific table:
For more information, see Chapter 6, Optimizer Overrides, in Tuning Cloudscape. Bulk Insert PropertiesYou can use a PROPERTIES clause to set the insertMode to bulkInsert or replace in an INSERT statement.
NEW: The ability to use fast load of bulk data on a published table in a source database is new in Version 3.0. If the table being inserted into also appears in the FROM clause, bulkInsert is ignored and Cloudscape performs an ordinary insert.
NEW: insertMode=replace is new in Version 3.0. For more information on importing external data, see the Cloudscape Tools and Utilities Guide. | ||
