18** Resolve an expression that was part of an ATTACH or DETACH statement. This-
19** is slightly different from resolving a normal SQL expression, because simple-
20** identifiers are treated as strings, not possible column names or aliases.-
21**-
22** i.e. if the parser sees:-
23**-
24** ATTACH DATABASE abc AS def-
25**-
26** it treats the two expressions as literal strings 'abc' and 'def' instead of-
27** looking for columns of the same name.-
28**-
29** This only applies to the root node of pExpr, so the statement:-
30**-
31** ATTACH DATABASE abc||def AS 'db2'-
32**-
33** will fail because neither abc or def can be resolved.-
