Clienteling isn’t a new theory. It can be traced back hundreds of years when shopkeepers …
The Sql Explorer has gone under some major reconstruction in 3.6 and subsequent updates. Among these changes include new features, as well as some UI improvements and updates.
Perhaps the first thing you will notice is the updated toolbar. In addition to the updated icons, the buttons on the toolbar are now split into two sections — the left “local” section and the right “global” section. The local buttons are relevant to the Sql Area, while the global buttons are relevant to the entire Sql Explorer. Let’s dive into these buttons.
The local buttons functionality has remained the same throughout this remodeling. However, there are three important improvements to take note of: the Sql History search bar, the “removal” of the Max Results field, and the “removal” of the Excel button.
The search bar runs a search on all the columns in a row to filter out unuseful rows. The Max Results field has been moved to the Settings button and the Excel functionality moved to the result tab, both of which will be discussed later on.
The global buttons are all new features to the Sql Explorer. The first button, Database Import, allows you to import data in multiple ways. You may import a SQL, XML, CSV, or SYM_XML file to manipulate your database. It is worth noting that the Table select only becomes active for CSV. The Table select may be pre-populated by highlighting the desired table in the Database Explorer and clicking the import button.
The second button, Database Export, allows you to export tables and/or data from your database. The first screen in this dialog requires you to select the tables you want to deal with. The tables you have highlighted in the Database Explorer will be selected by default.
The next screen allows you to choose your options for the export. It is worth noting that you have two choices for the Export Format: Export as a File and Export to the SQL Editor. The former will export to a downloadable file while the latter while export to the SQL Editor in the Sql Explorer.
The third button, Database Fill, allows you to fill tables with “junk” data. The first screen is the same table selection dialog as the Database Export button, which can be read about above. The second screen contains options for the fill.
The last button, Settings, allows you to change the Sql Explorer parameters, normally found in Configure->Parameters. The parameters will be pre-populated to their most recent value. Upon saving your changes, the parameters will be changed. It is worth noting that this is where the Max Results field has been moved to. A new parameter has also been added, Show Row Numbers, which if enabled, will show the row numbers in the result table of a query. This parameter is turned on by default. Note that for each query, you may choose to hide or show the row numbers without changing the parameter value by toggling the “#” column using the arrow on the far right of the column headers.
You may have noticed some new features and improvements in the previous picture of the Database Fill results. We will discuss those next.
The first improvement is the label underneath each tab. This label contains information for the result table. It displays the number of rows returned, or the number of rows limited to if the Max Results parameter in the settings is < than the rows returned from the query, as well as the query.
There are two new features for each tab to discuss, which are located on the right side of each tab. The first is a refresh icon. Clicking this will re-run the query that was run for that tab in that tab, essentially refreshing the tab itself. The next icon an export button. It allows you to export the result of the query in either Excel or CSV format. It is worth noting that this has replaced the functionality of the old Excel button.
There are a few new features to discuss in the result table itself. Rows are now double-clickable to bring up a window with the data from the row and column you double-clicked. If the column you double-clicked is of type binary, you will also be given the option to view the data as Hex, Text and Decimal.
Rows are also now right-clickable, which gives you the option to either Insert or Update the selected rows. These options will create the statement type you want and send it to the Sql Editor. Both of these options use the data from the rows to pre-populate the data in the statement.
The Database Explorer has also gone under some significant changes. The first and perhaps the most obvious being the checkbox to show sym_ tables. The checking and unchecking of this box will refresh the Database Explorer to include/exclude the SymmetricDS tables.
All nodes are now double-clickable in the Database Explorer. If the node is expandable (ie. Catalogs and Schemas), double-click will expand/collapse the node. If the node is not expandable (ie. Tables), the double-click will open the table’s properties, which will be discussed later.
In addition to being double-clickable, all nodes in the Database Explorer are now also right-clickable. If the node is expandable (ie. Catalogs and Schemas), the right-click will give the option to refresh the Database Explorer. If the node is not expandable (ie. Tables), the right-click will give you a list of options.
Browse will open a new tab in the result area for each highlighted table, running a SELECT * FROM query. There are a few differences between Browse and the next option, Select From. Browse simply opens a tab for each of the selected tables without putting anything into the Sql Editor. Select From, however, writes a select statement that includes the column names and puts it into the Sql Editor.
Insert Into and Update Set create their respective statements on the selected table(s), using the default values for each column’s JDBC type. Drop will drop the selected table(s) after a confirmation dialog. Please note that this action is final and cannot be undone. Drop will not cascade, so if there are other tables that depend on the dropped table(s), you should take note of these before you confirm to drop the selected table(s).
Import, Export and Fill have the same functionality of the buttons in the global section of the toolbar. Their inclusion in the right-click options is for convenience, as the table selections will pre-populate any highlighted tables in the Database Explorer.
Copy Name copies the selected table(s) fully qualified name to the Sql Editor at the spot of the cursor. It is worth noting that you may highlight multiple tables and copy their names with a space in between each name.
Properties is a replacement for the old right-click option “View”. Now a window pops up that contains a table of the table’s properties. In addition, the table’s catalog, schema, and name are now excluded. It is worth noting that this window may be popped up by double-clicking an un-expandable (ie. Table) node.
These new features and improvements have made the Sql Explorer easier to use and much more helpful in managing your Database. If you have any suggestions, feel free to leave a comment below!
