bool dd::sdi::check_privileges ( THD thd,
const Import_target t 
)

Parameters
thdthread handle
timport target context

◆ mdl_request()

MDL_request * dd::sdi::mdl_request ( const Import_target t,
MEM_ROOT mem_root 
)

Creates an MDL_request for exclusive MDL on the table being imported.

Parameters
timport target context
mem_rootwhere to allocate the MDL_request
