The Parameters tab contains the list of the current Function parameters with its options. Here you can view the Name and the Type of each Function parameter and also supply a Comment for the parameter.

Parameters can be edited within the Parameter Editor dialog window. In order to open the dialog you should

•	open the object in its editor and the Parameters tab there;

•	select the parameter to edit;

•

press the Enter key or select the Edit Parameter item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).
The Definition field contains the definition of the Function. Specify a string constant defining the Function here; the meaning depends on the language. It may be an internal Function name, the path to an object file, an SQL command or text in a procedural language.

Name

You can edit the Function name here. The name of the Function must be unique among all the Function names in the database.

Owner

The field contains the owner of the Function. By default, only the owner of an object can perform various operations with the object. In order to allow other users to operate it, privileges must be granted. (However, users that have the superuser attribute can always access any object.)

Comment

Specify a comment to the Function if necessary.

Data access (Contains SQL, No SQL, Reads SQL, Modifies SQL)

Use the clause to change the information about the nature of data use by the routine.

Contains SQL -	indicates that the routine does not contain statements that read or write data.
No SQL -	indicates that the routine contains no SQL statements.
Reads SQL -	indicates that the routine contains statements that read data, but not statements that write data.
Modifies SQL -	indicates that the routine contains statements that may write data.

Deterministic

Check the option if the function always produces the same result for the same input parameters, and uncheck otherwise.

SQL security

Use the characteristic to specify whether the routine should be executed using the permissions of the user who creates the routine or the user who invokes it. The creator or invoker must have permission to access the database with which the routine is associated. It is necessary to have the EXECUTE privilege to be able to execute the routine. The user that must have this privilege is either the definer or invoker, depending on how the SQL security characteristic is set. The clause was added in MySQL 5.1.8.

Return type

The field defines the data type of the function result.

To apply the changes, select the Apply Changes item in the Navigation bar or use Ctrl+F9 or Ctrl+F7 shortcut keys.

It is also possible to modify object properties without opening the object editor: use the Object Properties item of the popup menu of the selected object from the explorer tree.
