If the MySQL Model page is active, the selected object is deleted from the catalog and there will be no confirmation dialog box. Choose Edit Selected to edit the currently selected object. You can also perform edits in a new window by selecting Edit Selected in New Window. Similar Figures Objects of the same type : Finds objects similar to the currently selected object. Connected Figures : Finds all the objects connected to the currently selected object.
These menu items are active only when an EER Diagram tab is selected. When multiple objects have been selected using one of these menu items, you can navigate between selected items by choosing the Go to Next Selected or Go to previous Selected menu item. Selecting objects changes some of the Edit menu items. If only one object is selected, that object's name appears after the Cut , Copy and Delete menu items. If more than one object is selected, these menu items show the number of objects selected.
The Find dialog options are described in the following list:. Ignore Case : A search method that is not case-sensitive. Works with both the String Matching and Regular Expression search methods. Enabled by default. Match Whole Words : If enabled, only whole strings are matched.
Disabled by default. Wrap Around : The search will wrap around to the beginning of the document, as otherwise it will only search from the cursor position to the end of the document. And the arrows jump to the discovered search terms, and behave according to the Wrap Around option. Current View: Searches the current view only. Selected Figures: Searches the currently selected objects. This feature works only for EER diagrams.
Enter the text you wish to search for in the Find Text list. You may also select any or all of the following check boxes:. Any text you enter into the Find Text list is retained for the duration of your session. Use the Next or Previous buttons to find occurrences of your search criterion. Clicking the Find All button opens a Find Results window anchored at the bottom of the application. If you wish, you may undock this window as you would any other.
Use this window to navigate to objects. For example, double-clicking the Description of an object located on an EER diagram navigates to the specific diagram and selects the object. Notice that the properties of the object are displayed in the Properties palette. Close the Find dialog window by clicking the x in the top right corner or by pressing the Esc key. For further information, see Section 3. These options change depending on the current tab, and here are the available View menu items:.
Panels : Configure which of the three available panels are open. Windows : A submenu with items that activate slide open specific panels. The ability to zoom in on an EER diagram is also available using the slider tool in the Model Navigator palette. See Section 9. Set Marker : Bookmarks an object. You may create up to nine markers. Go To Marker : Returns to a marker.
From the keyboard, use the Control key and the number of the marker. The Arrange menu has these items:. Align to Grid : Aligns items on the canvas to the grid lines. Bring to Front : Brings objects to the foreground. Send to Back : Sends objects to the background. Center Diagram Contents : Centers objects on the canvas. Autolayout : Automatically arranges objects on the canvas. For example, if a table has a long column name that is not fully displayed, this menu item expands the table to make the column visible.
This menu item is not enabled unless an object is selected. This item will display a table's columns if the object notation supports expansion. Some object notations, such as Classic , do not permit expansion or contraction. Indexes will not automatically be expanded unless they were previously expanded and have been collapsed using the Collapse All menu item.
Collapse All : Undo the operation performed by Expand All. When a model is opened, this menu features actions to perform against your model, and the Model menu has these items:. User Defined Types : Presents a dialog box that enables you to add and delete user defined data types. For information about this menu item, see Section 9. Object Notation : For information about this menu item, see Section 9.
Relationship Notation : For information about this menu item, see Section 9. Diagram Properties and Size : Opens a diagram size dialog box that enables you to adjust the width or height of the canvas. The unit of measure is pages; the default value is two. When you have tables with numerous columns, use this menu item to increase the size of the EER. Model Options : Sets options at the model level. These options should not be confused with the options that are set globally for the Workbench application, and which are referred to as Workbench Preferences.
The available model options are a subset of the Workbench Preferences options. For more information about Workbench Preferences, see Section 3. Use this dialog window to set the options for creating documentation of your database models. Use these submenus for general validation and MySQL-specific validation of the objects and relationships defined in your model.
Validate All : Performs all available validation checks. Empty Content Validation : Checks for objects with no content, such as a table with no columns. Table Efficiency Validation : Checks the efficiency of tables, such as a table with no primary key defined. Duplicate Identifiers Validation : Checks for duplicate identifiers, such as two tables with the same name.
Consistency Validation : Checks for consistent naming conventions. Logic Validation : Checks, for example, that a foreign key does not reference a nonprimary key column in the source table. Integrity Validation : Checks for invalid references, such as a table name longer than the maximum permitted. Syntax validation : Checks for correct SQL syntax. Duplicate Identifiers Validation Additions : Checks for objects with the same name.
For detailed information about validation, see Section 9. Workbench Default : Displays table columns, indexes, and triggers. Workbench Simplified : Shows only a table's columns. Classic : Similar to the Workbench Simplified style showing only the table's columns. The object notation style that you choose persists for the duration of your MySQL Workbench session and is saved along with your model.
If you plan to export or print an EER diagram be sure to decide on a notation style first. Changing notation styles after objects have been placed on a diagram can significantly change the appearance of the diagram. The Relationship Notation submenu has these items:. Crow's Foot IE : The default modeling style.
For an example, see Figure 9. Classic : Uses a diamond shape to indicate cardinality. To view the different styles, set up a relationship between two or more tables and choose the different menu items. The relationship notation style that you choose persists for the duration of your MySQL Workbench session and is saved along with your model.

Here is a simple hibernate code that inserts a value into a table. If the row already exists, query the row and return the data. Most of the time, the code works fine with no issues. In a very special case, three different clients are trying to insert the exact the same row into the table. Ofcourse, only one row gets inserted. The other two insertions fail and the fall into the try-catch block.
There is a query in the try catch block, which queries the data and sends the value to the client. This results in an error for subsequent operations on the session. AssertionFailure - an assertion failure occured this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session " in the logs. I have some huge files which I have to import to the DB.

It is correctly giving me the list of the beers with blanks filling in the dates where no beers were brewed, but it lists beers that have the same date in different array elements and I want them to show in the same one. Like so:. The reasoning behind this is that this array is shown when a user hovers over the corresponding bar on chart. So rather than showing the number of beers brewed for that date I want it to give the names of all the beers brewed on that date. I found this article which was able to help me group each beer that was brewed on the same date in the same array element but now they are not ordered according to date as all the blanks have been moved to the beginning of the array:.
