Why Am I Getting \'Error: Access Denied; you need the SUPER privilege for this operation\' When Creating Functions in phpMyAdmin?

Error: Access Denied: Creating Functions in phpMyAdmin

When executing SQL queries to create functions in phpMyAdmin, users may encounter an "Error: Access denied; you need the SUPER privilege for this operation" message. This error stems from a privilege requirement.

Identifying the Problem

Two main issues can cause this error:

1. Missing CREATE ROUTINE Privilege: MySQL 5.0.3 and above require the CREATE ROUTINE privilege to execute CREATE PROCEDURE and CREATE FUNCTION queries.
2. DEFINER Restriction: The DEFINER attribute specifies the user who owns the stored procedure or function. If the DEFINER is set to a restricted user, the caller must have the SUPER privilege to create the object.

Solution

Remove DEFINER Attribute:

To eliminate the need for the SUPER privilege, remove the DEFINER attribute from the SQL query. This grants ownership of the function to the current user.

<code class="sql">CREATE FUNCTION `f_calc_gst`(p_ht decimal(15,3), p_province varchar(2)) RETURNS varchar(255) CHARSET utf8
...</code>

Set Delimiter Field in phpMyAdmin:

Before executing the modified query, ensure that the delimiter field is set correctly under the SQL text box in phpMyAdmin.

Additional Notes:

• Binary logging may require the SUPER privilege.
• Once the function is created, users can grant specific privileges to other users or roles.
