Oracle JDBC Driver￼4 min read
Benefits and Features of Oracle JDBC Driver:
Oracle’s JDBC Driver provides an easy-to-use interface for connecting to your database. It includes numerous benefits and features such as Bind by Name, Support for LDAP and SSL, and streaming data.
It also features multiple authentication methods. To connect to Oracle, select the Oracle Connect tab and enter your host and port.
Bind by Name Oracle JDBC Driver:
To use Bind by Name for Oracle JDBC driver, you should first understand the concept of named parameters. Named parameters are stored in the database in a specific order.
They are often expressed as ‘foo’, ‘?foo’, or ‘:foo’. These parameters are used to maintain the order of names in SQL. Then, you should use the setFooAtName(String, Foo) function to bind the value at each position.
The Bind by Name feature of the Oracle JDBC driver supports binding by name in SQL. This means that you can use the name of the stored procedure that you are calling.
But, you should only use this feature in procedure calls. For example, if you want to use the ‘?’ symbol in a query, you should use the ‘named’ symbol instead of ”’. Otherwise, you will get different results.
Bind by Name is a bit slower than bind by position in the Oracle JDBC driver. This is because it takes longer to bind parameters for a larger query with more bind variables. If you have 10M rows in your table, it will take a few seconds longer to bind the variables.
Reduces round trips to the server:
Oracle JDBC Driver helps you reduce round trips to the server by allowing you to specify the type of columns in a query. This parameter specifies the type of columns you want to retrieve and applies to both the input and output of the query.
To specify the type of columns in a query, simply type the data type of each column in the expected result set. The number of columns in the result set must match the number of columns in the query. If the number of columns in a query is not known, you can use the “%” wild card.
A Java application can make use of the JDBC Thin driver, which connects directly to Oracle through Java sockets. This eliminates the need for a middle-tier and the need for an HTTP proxy. To use this driver, you need to have a Java platform that supports sockets.
The other option is to use a Type 2 JDBC driver that connects to the server using Oracle Call Interface. This driver uses native methods to interact with the database instead of sending requests to the database server over HTTP.
Supports LDAP and LDAP over SSL:
The LDAP Driver is an LDAP client and server library written in Java. It provides CRUD and read-only operations and supports standard SQL server and MySQL client libraries.
Also, It also includes powerful remoting capabilities and supports Oracle’s Enterprise-class security standards. It also supports large-scale data requests and is suitable for any solution architecture.
LDAP over SSL is an advanced security feature that offers authentication and encryption. This secure layer of security enhances the standard TCP/IP protocol.
During the connection, the server and client negotiate cipher suites and encryption algorithms to ensure the confidentiality and integrity of data.
When connecting to an LDAP database, you should set the database URL to include an account identifier and a role.
You can use a string like ‘a to specify the account identifier. The string is followed by the database URL for the server-side driver.
Supports streaming data Oracle JDBC Driver:
Streaming data is one of the features of Oracle JDBC Driver. In this mode, the JDBC driver transfers the data in LONG or RAW columns to the client.
While transferring data, the JDBC driver does not read the data from the network until it is required. It then waits for the next() call before returning the data.
There are four types of Oracle JDBC drivers. All of them have similar features, but some of them are platform-specific.
Some of them support only JDBC OCI or JDBC Thin. It is best to use the appropriate driver for your needs. However, if you need streaming data functionality, you can use a Java driver.
This driver supports streaming data for BLOB and CLOB data. It also supports converting between binary and ASCII character sets.
Also, It can support converting between ASCII and Unicode. It also supports Unicode 1.2. This means that you can use it to store data in different languages.
