[MariaDB discuss] insert multiple SET type values in prepared statement?

Trying to insert multiple values of a SET type column using (MariaDB) prepared statements, but keep running into "Data truncated for column <columnN>" no matter how the multi-value string is formatted. Processing is done using PHP-8.2. ... INSERT INTO <table> SET ....<columnN=?> ....; $BindValuesArray[<columnN>]="'value1,value2,value3'"; $BindVarsArray[]=&${$<columnN>}; $BindParamTypes.="s"; ... extract($BindValuesArray); So, trying to insert a (multi-valued) "list string" into a SET type column.
