check_validity_m

If mstruct is not null, then checks that all the database objects referenced in the statement i actually referenced in mstruct (for example the table being updated in a UPDATE statement must exist in the connection's database for the check to succeed).

This method sets the this->validity_meta_struct attribute to mstruct.

If mstruct is null, then remove any information from a previous call to this method stored in this. In this case, the this->validity_meta_struct attribute is cleared.

Also note that some parts of this may be modified: for example leading and trailing spaces in aliases or objects names will be removed.

Parameters:

this	a SqlStatement pointer
mstruct	a MetaStruct object, or null

Returns:

TRUE if no error occurred
