Creating and altering tables does not require memorizing complex DDL syntax.
Creating a Table: Right-click the Tables node in DB Explorer and select New Table. Use the visual designer to add column names, select DB2 data types, and check boxes for Null or Identity properties.
Setting Primary Keys: Switch to the Keys tab within the table designer, click Add, and select your primary key columns.
Compiling Changes: Click the Compile button (or press Ctrl+F9) to execute the structural updates on the DB2 server. 2. Working with the SQL Editor
The SQL Editor caters to both advanced developers and beginners.
Execution: Write your script and press F9 to execute the entire tab, or highlight a specific statement and press Ctrl+F9 to execute a partial block.
Code Intelligence: Use Ctrl+Space to trigger code completion for table names, schemas, and columns.
Visual Query Builder: If you prefer a drag-and-drop workflow, click the Query Builder tab. Drag tables onto the canvas, check the columns you want to select, and draw lines between tables to automatically generate SQL joins. 3. Data Manipulation and Exporting Viewing and editing table data happens safely and visually.
Grid Mode: Double-click any table in DB Explorer and navigate to the Data tab. You can insert, edit, or delete rows directly in the grid. Remember to click the Commit button to save changes.
Data Export Wizard: Right-click a table or query result and choose Export Data. The wizard supports 15+ formats, including Excel, CSV, XML, and JSON. You can map columns, set data formats, and save the export configuration for future use.
Data Import Wizard: Easily populate tables from external files by selecting Import Data and mapping your source file columns to the target DB2 table columns. 4. DB2 Security Management
Administering user permissions is fully integrated into the UI.
Users and Groups: Expand the Security node in the DB Explorer to add new database users or roles.
Granting Privileges: Open a user profile, navigate to the Privileges tab, and visually check options to Grant or Revoke SELECT, INSERT, UPDATE, or DELETE rights on specific schemas and tables. 💡 Pro-Tips for Optimization
Keyboard Shortcuts: Master F12 to toggle the DB Explorer panel visibility, clearing up screen real estate for massive SQL scripts.
Transaction Control: By default, EMS SQL Manager may run in Autocommit mode. Toggle this off in the Environment Options if you are running destructive updates, allowing you to explicitly click Commit or Rollback.
Favorite Queries: Save frequently used administrative scripts to the SQL Templates panel for instant recall.
