Useful methods to retrieve metadata from the database server: For information on the advantages of using client datasets to cache updates, see Using a client dataset to cache updates Client datasets can apply edits directly to a database server when the dataset is read-only. It should be a DN which has read access to the replication content in the master database.
Conceptually data is handled in table form - each row required is buffered internally.
The ClientDataSet component, which can be used in place of other DataSet components, permits for the reading and writing of single user flat files. Client applications created using MIDAS are often referred to as thin clients, since they require less configuration and fewer files specifically, no BDE.
Also, unidirectional datasets can only supply a single record at a time Specialized datasets require an appropriate type of connection Finally, the connection component connects to the actual database, either file- or server-based.
Structures] and when checking value constraints. The bindmethod is simple or sasl, depending on whether simple password-based authentication or SASL authentication is to be used when connecting to the provider slapd instance. A very few datatypes have other relations or operations prescribed for the purposes of this specification.
If the mapping is restricted during a derivation in such a way that a value has no denotation, that value is dropped from the value space. A list of length one containing a value V1 and an atomic value V2 are equal if and only if V1 is equal to V2.
You can reduce network traffic by using a dataset that caches updates locally and applies them all later in a single transaction.
Once a connection is established, the timeout parameter determines how long the consumer will wait for the initial Bind request to complete. In the refreshOnly operation, the next synchronization search operation is periodically rescheduled at an interval time after each synchronization operation finishes.
Columns are represtented using Fields. Components in the Data Access page can be used with any data access solution, and include TClientDataset, which can work with data stored on disk or, using the TDataSetProvider component also on this page, with components from one of the other groups.
This directive is only applicable in a slave or shadow slapd 8 instance. When using dbExpress, this is the only way to edit the data in the dataset it is also the only way to navigate freely in the data when using dbExpress.
In the few cases where it is not, equality has been carefully defined so that for most operations of interest to the datatype, if two values are equal and one is substituted for the other as an argument to any of the operations, the results will always also be equal.
The defaults for these parameters come from ldap. The weak order "less-than-or-equal" means "less-than" or "equal" and one can tell which.
Both sizelimit and timelimit default to "unlimited", and only positive integers or "unlimited" may be specified.
The preferred method for executing statements that return data is to use a dataset. The network-timeout parameter sets how long the consumer will wait to establish a network connection to the provider.
Thus, if one database suffix is a prefix of another, it must appear after it in the config file. Unlike the BDE, dbExpress returns only unidirectional cursors and therefore does no caching. A connection component uses this list, for example, to close all of the datasets when it closes the database connection.
SASL authentication is generally recommended.Configuration File Format. The mint-body.com(5) file consists of three types of configuration information: global, backend specific, and database mint-body.com information is specified first, followed by information associated with a particular backend type, which is then followed by information associated with a particular database instance.
