- sqlQuery string|ParameterizedQuery - The query which needs to be executed as
stringorParameterizedQuerywhen the SQL query has params to be passed in
- rowType typedesc<record {}>? (default ()) - The
typedescof the record that should be returned as a result. If this is not provided the default column names of the query result set be used for the record attributes.
Return Type
execute
