Tables

Tables are database objects that contain all data in a database. A table is a set of rows and columns, and their intersections are fields. In the main window, click Table to open the table object list.

There are two ways to open a table with graphical fields, right-click a table and choose:

Option Description

Open Table Navicat loads all your BLOB fields (images) while opening the table.

Open Table (Quick) Faster performance for opening the graphical table, as BLOB fields (images) will not be loaded until you click on the cell. (It is invisible by default until you hold down the SHIFT key when right-clicking the table.)

You can create a table shortcut by right-clicking a table in the Objects tab and select Create Open Table Shortcut from the pop-up menu. This option is used to provide a convenient way for you to open your table for entering data directly without activating the Navicat main window.

To empty a table, right-click the selected table and choose Empty Table from the pop-up menu.

Table Designer

Table Designer is the basic Navicat tool for working with tables. It allows you to create, edit and drop table's fields, indexes, foreign keys, and much more.

In the Fields tab, you can search a field name by choosing Edit -> Find or pressing CTRL+F. When creating a new table, you are allowed to insert fields or rearrange the order of the fields.

Note: The tabs and options in the designer depend on the server version.

Table Viewer

When you open a table, Table Viewer displays data as a grid. Data can be displayed in two modes: Grid View and

Form View. See Data Viewer for details.

Views

A view allows users to access a set of tables as if it is a single table. You can use views to restrict access to rows. In the main window, click View to open the view object list.

You can create a view shortcut by right-clicking a view in the Objects tab and select Create Open View Shortcut from the pop-up menu. This option is used to provide a convenient way for you to open your view directly without activating the Navicat main window.

If an error occurs while executing the procedure/function, execution stops, the appropriate error message is displayed. If the procedure/function requires input parameters, the Input Parameter dialog will pop up. Check the Raw Mode option to pass the inputted values to the procedure/function without quotation marks.
