Tools - Table Data Editor

Table Editor - Aqua Data Studio provides a Table Editor which allows a user to graphically edit the resultset of an executed query.

To activate a table editor you must write a single-table SELECT statement and use the "Execute Edit" button. This will execute the query and return the resultset in a new Table Editor window. From this window a user may edit and save the contents of the resultset.

The editor uses the primary key or any unique constraint to identify the row in the result which it will generate UPDATE statements for. If your resultset doesn't have a primary key or unique constraint, you will be prompted to define a primary key in the primary key tab.

There is now an option within File->Options->Permissions to allow Primary Key Definition Changes.

• "Edit in window" option has an extra tab that provides an editor which wraps the text so the user may edit in a regular or a wrapped text mode.
• "Save SQL" stores the chosen directory path and uses it for subsequent save operations as a default directory for easier navigation
• Preview panel: The preview panel creates a cells preview at the bottom split panel to allow the user to preview the currently selected value in the grid. This allows the user to easily see the full value, including long string values or CLOB values.
• Status Bar has "Total Rows:" information at the bottom right to show the number of rows in the table.
• After the changes are saved and the table is refreshed (Save and Refresh), the cursor selects the first cell of the selected row before save.
• Edit->Format: AutoFit Column Width - Cells can be highlighted and resized automatically using the menu, a key shortcut, or a double-click on the right border of the column header. This option can be cofigured from the dropdown menu.
• Edit->Next Tab: Move to next tab; Edit->Previous Tab: Move to previous tab; Edito->Focus Max Results: Move focus to the max results.
• File->Options:General: Moved Table Data Editor options to Table Data Editor section.
• When closing a modified window the application will prompt for "Save," "Discard" and "Cancel."

• Entering a string value with length longer then the datatype can handle will notify the user of a possibility for truncation.
• Editing a cell with a key stroke will clear the cell and start the cell value from the key typed. Editing the cell with a mouse double click will edit the cell but will leave the old value.
• Edit->Clone Selected Rows - Clones the selected rows. This option can also be accessed from the dropdown menu.
• Edit->Insert Current Date Only: Inserts the current date, and a time of 12:00 p.m. if the date type is a timestamp. This option can also be accessed from the dropdown menu.
• DateTime columns: If the user enters or pastes a date or datetime in a different format then the default locale, ADS will make a conversion. Example: 8/9/06 will be converted to 08/09/2006 12:00:00 AM
• Fill Functionality as Edit->Fill Down and Edit->Fill Right: Fills currently selected cells in the chosen direction with the first selected cell content. This option can also be accessed from the dropdown menu.
• "Paste" now pastes the value from the clipboard into all the selected cells.
• A user can copy a row and then paste it into an empty row. Select row, press CTRL-C, then select another row and press CTRL-V.
• A user can copy x number of rows and paste into the last empty row and the necessary number of rows will be created.
• Pasting into a cell from a spreadsheet:
  • Pasting into a cell in edit mode will trim carriage return ("/r")
  • If a user copies one cell from a spreadsheet and pastes it into a single cell of the Table Data Editor it will paste the value without trailing carriage returns and line feeds.
  • If the user copies one cell from a spreadsheet and paste it into a number of selected cells, the Table Data Editor will paste the single cell into each individual cell.
  • If the user copies a block of cells from a spreadsheet then the Table Data Editor will paste the block into the corresponding cells starting from the leading selected cell; whether a single cell or multiple cells are selected does not change the functionality.

• If no results are returned, an error message is displayed.
• Warnings are displayed when warnings are returned.
• If a statement is executed that doesn't make any modifications, the transaction is still commited. Example: Deleting a row which has already been deleted by a different user.
• The table data editor is now threaded, and there is a status bar at the bottom that displays the status of execution. Including in the status bar is the number of statements to be executed and on which execution it is on. The toolbar has a cancel button so that the user may cancel the execution at any given time.
• If Save is cancelled while being executed, the status bar displays the total number of statements executed before the cancel.
• Transaction Handling:
  File->Options:Table Data Editor: Added section for Table Data Editor Options.
  • Transactions: Transaction Type: {Full, Batch, Threshold} :
  • Full: A "Full" transaction type causes all changes to be made in one transaction. This is the default.
  • Batch: A "Batch" transaction type will batch all the statements to be executed into batches with an X number of statements per batch. Each batch will be commited independently. If a commit fails, the execution will stop and rollback the current transaction batch, but it will not be able to rollback the previosly executed transaction batches.
  • Threshold: A "Threshold" transaction batch executes the statements in order and checks the amount of time ellapsed after each executed statement since the beginning of the batch. If the time ellapsed has reached the threshold time, the current transaction will be committed, and a new transaction will be started. This will allow the statements to be batched in separate transactions based on a time Threshold.
  • Batch Size: Number of statements per transaction batch [For Transaction Type: Batch].
  • Threshold: Number of milliseconds ellapsed to trigger a transaction batch commit [For Transaction Type: Threshold].
  • Wait Time: Amount of time to wait between transactions [For all Transactions].
  • Transaction Log Monitor [Sybase ASE]: This will allow ADS to queue editor modifications for Sybase ASE if the Transaction Log percentage hits a certain Threshold which allows the server to process the current transactions before receiving requests from ADS.
    • Log Used Threshold: Percentage of transaction log used that would trigger a transaction to wait.
    • Log Used Wait Time: Time to wait if a transaction log used threshold is triggered.

• Edit->Find: Finds the first occurence of the text in the grid values starting from the current position and using the specified direction for search.
• Edit->Find Next: Find the next occurance of the last find.
• Edit->Find Previous: Find the previous occurance of the last find.
• Edit->Replace: Finds and replaces a string occurence(s) by a specified string; if it replaces all of the occurences in the table, it shows how many have been replaced.
• String matching options for Find and Replace: "match case", "match entire cell" and "match whole words."

• Quick Selection - Ctrl-Shift-R and Ctrl-Shift-K (by default) selects all the rows or columns respectively that have cells that are currently selected.
• Default Key Binding for Delete Row is Ctrl-Delete, for Clear Changes is Ctrl-Alt-Z and for Clear Cell Changes is Ctrl-Alt-Y.
• Key "Edit" will overwrite, F2 will put in edit mode with text highlighted and mouse double click will put in edit without highlight.
• DELETE Key: sets to NULL all the selected cells.
• CTRL-D Key: deletes the row.

Table Data Editor Enhancements

• Sortable Columns: To sort by a certain column a user can click on that particular column. The first click will sort in ascending order, the second in descending order and the third will unsort the column values. Simultaneous multiple column sorting is available if the user keeps the Ctrl key pressed.
• Filterable Rows: Quick filter field is available at the top right corner to help the user to filter and view desired column values. If the user clears changes which were in the filter so that the rows are no longer in the filter, the view stays the same for user convenience until a new filter is applied.
• Multi-Table Editing: Table Data Editor now allows the user to insert an empty row before and after any row in the table. Cloned rows are now inserted directly after the row being cloned.
  Limitations
  1. Columns with the same name belonging to different tables are not editable because the table they belong to cannot be identified.
  2. Insert, clone and delete row operations are not available in the multitable mode as they can't distinguish between the tables.
  
• Insert Row Before & After: Table Data Editor now allows the user to insert an empty row before and after any row in the table. Cloned rows are now inserted directly after the row being cloned. If the corresponding columns are sorted, the view stays the same until new sorting is applied.
• Status Bar: Now, if data loading takes an extended period of time, a progress bar pops up to show that the operation is in progress.
• Option to save queries to SQL History: This option can be enabled/disabled in File->Options[Table Editor]. When the option is enabled, queries generated in Table Data Editor are saved to SQL History after being executed and commited. With the Full (default) transaction type all of the queries are saved as one entry, otherwise queries are saved by batches being commited. If a query or a batch fails, including the case when a user cancels it, further queries are not executed and not saved.
