Database Objects■■■■■■■■Table: Table actions include Rename, Copy (create a copy using a different name),Drop (delete the table), Truncate (delete existing data without affecting the tabledefinition), Lock (set the table lock mode: row share, exclusive, and so on),Comment (descriptive comment explaining the use or purpose of the table),Parallel (change the default degree of parallelism for queries and DML on thetable), No Parallel (specify serial execution), and Count Rows (return the numberof rows).Export: Enables you to export some or all of the table data to a file or to the systemclipboard, in any of the following formats: XML (XML tags and data), CSV(comma-separated values including a header row for column identifiers), SQLInsert (INSERT statements), or SQL Loader (SQL*Loader control file). After youselect a format, the Export Table Data dialog box is displayed.Column: Column actions include Comment (descriptive comment about acolumn), Add, Drop, and Normalize.Index: Options include Create (create an index on specified columns), Create Text(create an Oracle Text index on a column), Create Text (create a function-basedindex on a column), and Drop.Storage: Options include Shrink Table (shrink space in a table, for segments intablespaces with automatic segment management) and Move Table (to anothertablespace). The Shrink Table options include Compact (only defragments thesegment space and compacts the table rows for subsequent release, but does notreadjust the high water mark and does not release the space immediately) andCascade (performs the same operations on all dependent objects of the table,including secondary indexes on index-organized tables).Analyze: Options include Compute Statistics (compute exact table and columnstatistics and store them in the data dictionary), Estimate statistics (estimate tableand column statistics and store them in the data dictionary), and ValidateStructure (verifies the integrity of each data block and row, and for anindex-organized table also generates the optimal prefix compression count for theprimary key index on the table). Both computed and estimated statistics are usedby the Oracle Database optimizer to choose the execution plan for SQL statementsthat access analyzed objects.Constraint: Options include Enable or Disable Single, Drop (delete a constraint),Add Check (add a check constraint), Add Foreign Key, and Add Unique.Privileges: If you are connected as a database user with sufficient privileges, youcan Grant or Revoke privileges on the table to other users.■ Trigger: Options include Create, Create PK from Sequence (create a before-inserttrigger to populate the primary key using values from a specified sequence),Enable or Disable All, Enable or Disable Single, and Drop (delete the trigger).You can perform the following operations on a column in a table by right-clicking thecolumn name in the Connections navigator and selecting an item from the menu:■■■■Rename: Renames the column.Drop: Deletes the column (including all data in that column) from the table.Encrypt (for Oracle Database Release 10.2 and higher, and only if the TransparentData Encryption feature is enabled for the database): Displays a dialog box inwhich you specify a supported encryption algorithm to be used for encrypting alldata in the column. Current data and subsequently inserted data are encrypted.Decrypt (for Oracle Database Release 10.2 and higher, and only if the TransparentData Encryption feature is enabled for the database): Decrypts data in the column1-10 SQL Developer Online Help
Database Connectionsthat had been encrypted, and causes data that is subsequently inserted not to beencrypted.For conceptual and usage information about tables, see Managing Tables.1.2.13 TriggersTriggers are stored PL/SQL blocks associated with a table, a schema, or the database,or anonymous PL/SQL blocks or calls to a procedure implemented in PL/SQL or Java.Oracle Database automatically executes a trigger when specified conditions occur. Forconceptual and usage information about sequences, see Triggers: Usage Information.For help with specific options in creating a trigger, see Create Trigger.1.2.14 TypesA data type associates a fixed set of properties with the values that can be used in acolumn of a table or in an argument of a procedure or function. These properties causeOracle Database to treat values of one data type differently from values of anotherdata type. Most data types are supplied by Oracle, although users can create datatypes.For conceptual and usage information about data types, see Data Types: UsageInformation. For help with specific options in creating a user-defined type, see CreateType (User-Defined).1.2.15 Users (Other Users)Database users are accounts through which you can log in to the database. In theConnections navigator, you can see the Other Users in the database associated with aconnection, but the database objects that you are allowed to see for each user aredetermined by the privileges of the database user associated with the current databaseconnection.1.2.16 ViewsViews are virtual tables (analogous to queries in some database products) that selectdata from one or more underlying tables. Oracle Database provides many viewcreation options and specialized types of views (such as materialized views, describedin Materialized Views), to meet a variety of enterprise needs. For conceptual and usageinformation about views, see Managing Views. For help with specific options increating and editing a view, see Create/Edit View.You can perform the following operations on a view by right-clicking the view namein the Connections navigator and selecting an item from the menu:■■■Edit: Displays the Create/Edit View dialog box.Drop: Deletes the view.Compile: Recompiles the view, to enable you to locate possible errors before runtime. You may want to recompile a view after altering one of its base tables toensure that the change does not affect the view or other objects that depend on it.1.3 Database ConnectionsA connection is a SQL Developer object that specifies the necessary information forconnecting to a specific database as a specific user of that database. You must have atleast one database connection (existing, created, or imported) to use SQL Developer.SQL Developer Concepts and Usage 1-11
