I need to update the email address field values from uppercase to lower case to make them uniform inside the data schema but it is not happening because email address is marked as Primary key.
Please help me to achieve this or please suggest any workaround.
But schema is already having dataPolicy="email". Should i update my custom schema or any other workaround? This is about email address field.
<attribute dataPolicy="email" desc="Email address" label="Email" length="128"
name="email" sqlname="sEmail" type="string"/>
