To restore the SQL Developer window to its original display, double-click the tab again.

Working with Databases

If you are using the OCI driver, you can set relevant parameters in the same way that you would in any Oracle client setting. The JDBC Thin driver supports the Oracle Advanced Security features through a set of Java classes included with the JDBC classes in a Java Archive (JAR) file and supports security parameter settings through Java properties objects. For example, if you open a table in the Connections navigator and two SQL Worksheets using the same connection, all three panes use one shared connection to the database. In this example, a commit operation in one SQL Worksheet commits across all three panes. If you want a dedicated session, you must duplicate your connection and give it another name. Sessions are shared by name, not connection information, so this new connection will be kept separate from the original.

Using Server, you can run transactions faster with enhanced performance and high availability. Additionally, in SQL Server 2022 you can analyze, integrate, and manage both unstructured and relational big data using big data clusters and data virtualization. sql dba developer To perform a search, enter values in the search criteria columns and click the search icon to locate the initialization parameter.

The Reports navigator (not shown in the preceding figure) lists informative reports provided by SQL Developer, such as a list of tables without primary keys for each database connection, as well as any user-defined reports.

6.2 Managing Pluggable Databases

SQL developers use structured query language (SQL) to create and modify database tables using CRUD SQL commands. CRUD is an acronym for create, read, update, delete and refers to the four operations developers perform on database tables to manipulate the data. To ensure your application’s security, avoid hardcoding database credentials in the source code. Instead, use environment variables or configuration files not stored in version control. The Waits page shows a chart with the distribution of wait events in real time. A segment is a set of extents allocated from a tablespace for a specific database object such as a table or index.
