infoDiagnostics information to be obtained.

Member Function Documentation

bool Sql_cmd_get_diagnostics::execute ( THD *  thd) [virtual]

Execute this GET DIAGNOSTICS statement.

thdThe current thread.
Errors or warnings occurring during the execution of the GET DIAGNOSTICS statement should not affect the diagnostics area of a previous statement as the diagnostics information there would be wiped out. Thus, in order to preserve the contents of the diagnostics area from which information is being retrieved, the GET DIAGNOSTICS statement is executed under a separate diagnostics area. If any errors or warnings occur during the execution of the GET DIAGNOSTICS statement, these error or warnings (conditions) are appended to the list of the original diagnostics area. The only exception to this is fatal errors, which must always cause the statement to fail.
Return values:
falseon success.
trueon error
