No, TABLE structure and the handler class. To open a P_S table as a normal table and read the data from it. See, e.g. sql_udf.cc or sql_acl.cc or sql_help.cc for an example of reading a table using low-level functions. > Is there a guide or document using PSI? It's a bit difficult to use PSI. No, it was never supposed to be used by plugins.
