Create functions in Navicat

The steps to create a function in Navicat are as follows:

1. Connect to the database

• Open Navicat and connect to the database where you want to create the function.

2. Navigate to Object Manager

• In the left panel, click the Object Manager icon.

3. Create a new function

• Right-click the Functions folder and select New Function.

4. Enter function details

• In the "New Function" window that pops up, enter the following details:

  • Function name: The name of the function.
  • Parameters: The function's parameter list (if required).
  • Return value type: The type of the value returned by the function.
  • Function body: the function code.

5. Determine the function type

• Select function type:

  • Deterministic: A function that always returns the same result.
  • Nondeterministic: A function that does not always return the same result.

6. Create a function

• Click the OK button to create the function.

Example:

Suppose we want to create a function called add_numbers that adds two numbers:

 <code class="sql">CREATE FUNCTION add_numbers(a INT, b INT) RETURNS INT DETERMINISTIC BEGIN RETURN ab; END;</code>

Once the function is created, you can use it in Navicat just like any other function.
