Instead, you can easily adjust index and key values via the alter table dialog. You are not allowed to edit these values here. The row count, grants, index, and primary key tabs are all provided for a quick view of the table properties. There is also a tab for references that can quickly provide a graphical view of the table within the schema and other tables it references. The detail view of a table includes tabs for the DDL from the DB and native DDL (source) that was used to create the table. Whether you want help in design or the documentation of it, you can use tools for each table. This tool extends from general administration to a full-featured IDE as well. The import can read a CSV or XLS file and scans for likely column headers then provides a wizard approach to handle the mappings. Although the import is not going to compete with a high-end data integration or ETL tool, it is perfect for those one-off tasks we always seem to be assigned. You can import or export a table or an entire database. The next step from scripting queries is imports and exports. This feature alone can save a lot of time throughout your tasks. There are also options to send the default query text to a file, the clipboard, or your working session. One of these is “Script Table.” This feature makes it easy to create a starting point for a query on a table whether it is an insert, update, or delete. You can right-click on a table to see a menu of options. One seems to continuously have to type out the column names and template text for queries. There can be a lot of tedium in database development and administration. If you want to quickly manipulate data, then this is the easiest way outside of using SQL. You can filter, sort, and even edit the data as well as export a selection. Select this tab to see the data in the table. There are some such tabs available in the table detail. However, more details are provided in the Columns tab when you double-click on the table name. You can quickly browse a table structure this way. For example, double-click on a table name to view details about it or display the child list to see the columns. Each of these items can be expanded to see a list of that type of objects available in the DB.Įach object type is a little different, but typically a double-click will open a view into the data while expanding the child list will show some details. Alternatively, the child list can be expanded to view tables, triggers, stored procedures, views, or more. A database can be double-clicked to see details about it. You can view this by expanding the children of the connection (left panel) and then opening the Databases row. The terminology varies by the vendor but roughly speaking there is a database that holds your tables. However, you are not likely to need to do this. Once you connect you can review the connection tabs to tweak it out. The output will either show a successful session creation or provide a detailed error message from the driver manager. Once you have a connection created, you can test it. Your driver is likely supported by default, and the application will build the proper connection string. At this point, you should be ok entering the data for each step of the wizard if you understand database connection strings. When you select that menu item, you will be asked if you want to use the wizard. You can click on the connections tab and then right click on the Connections item to see a menu that includes the option to create a database connection. The first step is to connect to a database. On the other hand, it is not hard to perform either option. If you have installed Java on your system, then it is best just to use that. When you install, you have the choice of installing a JDK or using one on the system. It is important to note that DBVisualizer is a Java application. This is an excellent way to help you decide whether that price is worthwhile. Note that the free version does allow for a twenty-one day trial of the paid version. However, you can see for yourself on their comparison page. The rough differences are that the free version is a data browser while the paid version adds a lot of administration and manipulation tools. There are two versions available, free and paid. A tool like this is too much to cover in an introduction so your best approach will be to use it. Although the uses are plentiful, we will keep this DBVisuualizer how-to focused on the standard features and usage. It is a database tool for developers and those that need to browse their data. One of the tools in this series that I have used the most is DBVisualizer.
