COM DDTEK JDBC SQLSERVER SQLSERVERDRIVER DRIVER

Specify the location and password of the truststore file used for SSL server authentication. An application can return values of auto-generated keys when it executes an Insert statement. The number of times the driver retries connections to a database server until a successful connection is established. When you specify a transaction group ID, all distributed transactions initiated by the connection are identified by this ID. The following query is an example of a Select statement that returns a result set that contains a generated column the column named "upper". Specifying a buffer size that is a power of 2 results in more efficient memory use. If you install the driver in a directory that is not on the Windows system path, perform one of the following actions to ensure the driver can load the DLLs:.

You can supply a security token by specifying one with the SecurityToken connection property or by appending the security token to the Password property.

Data Source and Driver Classes

The SQL Server driver supports the following methods of authentication: For example, if the value of col1 in the following Select statement is null, the comparison evaluates to true:. In this case, performance can be improved by increasing the amount of memory used by the driver before writing data to disk.

In addition, if this property is specified in a connection URL, the entire value must qslserverdriver enclosed in parentheses when multiple commands are specified. For example, for the following statement, the SQL Server driver returns "test" for the catalog name, "test1" for the schema name, and dddtek for the table name:.

Typically, the Direct method performs better than the Cursor method. See Distributed Transaction Cleanup for more information about distributed transaction cleanup.

Connecting to a Database

This property helps applications in which jdbx columns are all Unicode or all non-Unicode. For example, Password is the same as password. Explicit transaction cleanup provides more control than transaction timeout over when distributed transactions are cleaned up.

For example, to connect to Oracle instance named test on the server named corpserver1 on portthe following URL would be used: The default is 5.

As a general rule, applications should clean up orphaned connections at startup and when the application is notified that a connection to the server was lost.

The statement contains a predicate value expression part that is a nested query. The default is longvarchar.

For example, if your application specifies the following connection URL, the value of the Database connection property would be used instead of the value of the DatabaseName connection property.

Setting the following connection properties for the SQL Server driver as described in the following list can improve performance for your applications. The driver does not parse or remove any XML processing instructions. In this case, the getTableName method may return an empty string for each column in the result set.

Microsoft SQL Server only. Determines whether string parameters are sent to the Microsoft SQL Server database in Unicode or in the default character sqlservfr of the database.

To allow the Performance Wizard to launch without encountering a security warning message, the security settings in your browser can be modified. If set to x, where x is a positive integer, the driver caches long data jdb result sets in memory and uses this value to set the size in KB of the memory buffer for caching result set data. This file is configured to load automatically unless the java. See also Database Connection Property. To connect to a production instance of a Salesforce organization, for example, you would use the following URL: Data encryption may adversely affect performance because of aqlserver additional overhead mainly CPU usage required to encrypt and decrypt data.

Use this value only if your application retrieves columns in the order in which they are defined in the result set. The driver ignores any truststore information specified by the TrustStore and TrustStorePassword properties or Java system properties.

The MS SQL Server Driver

To improve performance when your application retrieves images, pictures, long text, or binary data, you can disable caching for long data on the client if your application retrieves long data column values in the order they are defined in the result set.

This allows an application to use the Snapshot isolation level with no or minimum code changes. Network authentication must be provided by Windows Active Directory on one of the following operating systems: In this case, the driver applies the standard JDBC binary-to-character conversion to the data, which returns the hexadecimal representation of the binary data.

When this connection property is set to true thereby, you are using Snapshot Isolationperformance is improved due to increased concurrency.
