Tables
A database table is a structure that organises data into rows and columns. Data in a table is stored in a cell that is an intersection of a vertical column and horizontal row. The table has a specified number of columns, but can have any number of rows. With RubyMine, you can perform data manipulation and data definition operations with tables.
When you double-click a table in the Database tool window (), the table is opened in the editor in the Table view. For more information about the view, see View data.
In RubyMine, each table opens in a separate tab. The following rules are applied to long tab titles:
The Always show qualified names for database objects option is now turned off by default. Tab names for objects are qualified if you open two tabs of objects with the same name. For example, if you open two
actortables from different schemas, the schema name is added in the tab name.If the data source has a name that is longer than 20 symbols, the name is truncated.
If you have only one data source, RubyMine does not display the data source name in the tab name.
If a qualified object name has more than 36 symbols, it is truncated.
