DB2 —DB2 5.2 native database driver.
Informix73 —Informix73 native database driver.
DBSERVER
Optional. For native database drivers and the SQLOLEDB provider, specifies the
name of the database server machine. If specified, DBSERVER overrides the server
specified in the data source.
DBNAME
Optional. The database name (Sybase System 11 driver and SQLOLEDB provider
only). If specified, DBNAME overrides the default database specified in the data
source.
USERNAME
Optional. If specified, USERNAME overrides the username value specified in the
data source setup.
PASSWORD
Optional. If specified, PASSWORD overrides the password value specified in the
data source setup.
MAXROWS
Optional. Specifies the maximum number of rows you want returned in the record
set.
BLOCKFACTOR
Optional. Specifies the maximum number of rows to fetch at a time from the
server. The range is 1 (default) to 100. This parameter applies to ORACLE native
database drivers and to ODBC drivers. Certain ODBC drivers may dynamically
reduce the block factor at runtime.
TIMEOUT
Optional. Lets you specify a maximum number of milliseconds for the query to
execute before returning an error indicating that the query has timed-out. This
attribute is not supported by most ODBC drivers. TIMEOUT is supported by the
SQL Server 6.x or above driver. The minimum and maximum allowable values
vary, depending on the driver.
CACHEDAFTER
Optional. Specify a date value (for example, 4/16/98, April 16, 1999, 4-16-99).
ColdFusion uses cached query data if the date of the original query is after the
date specified. Effective only if query caching has been enabled in the ColdFusion
Administrator. To use cached data, the current query must use the same SQL
statement, data source, query name, user name, password, and DBTYPE.
Additionally, for native drivers it must have the same DBSERVER and DBNAME
(Sybase only).
Years from 0 to 29 are interpreted as 21st century values. Years 30 to 99 are
interpreted as 20th century values.
