+# Generate Unique Value Based on Sequence
+
+The `execute()` function in action is generates a unique sequence value based on the existing sequence in a column of a table. This function inside a action script is designed to be used in database environments. It takes the following input parameters:
+
+- `table`: The name of the table to generate the unique value for.
+- `column`: The name of the column to generate the unique value for.
+- `default_value`: The default value to use if there are no records in the table.
+- `useLowerUpperBoth`: A Boolean value indicating whether to use both lower and upper case characters when generating the next sequence value.
+
+## Function Behavior
+
+1. The function begins by querying the specified table to retrieve all the values in the specified column.
+
+2. If there are records in the table:
+   - The function then generates the next sequence value based on the last value in the column.
+   - It automatically detects the type of sequence value to generate based on the postfix of the last value in the column:
+     - If the postfix ends with digits, the function generates a numeric sequence value.
+     - If the postfix ends with alphabetic characters, the function generates an alphabetic sequence value.
+   - If the `useLowerUpperBoth` parameter is set to `true`, the function will use both lower and upper case characters when generating alphabetic sequence values.
+   - If the `useLowerUpperBoth` parameter is set to `false`, the function will only use upper case characters when generating alphabetic sequence values.
+
+3. If there are no records in the table, the function returns the `default_value`.
+
+4. The function handles any exceptions by setting the output value to `null`.
