In SQLite 3.5.9 it used to be possible to write
sqlite> ATTACH '/some/unix/file/name.db' AS mydb;
In SQLite 3.6.22 this results in the error message
Error: unable to resolve operation
whereas
sqlite> ATTACH /some/unix/file/name.db AS mydb;
is a syntax error at '/'
The problem seems to be the indicated line in the function resolveAttachExpr
(located in attach.c). If the expression ALREADY IS a string, then it makes no
sense to call sqlite3ResolveExprNames() which CANNOT HANDLE a string.
static int resolveAttachExpr(NameContext *pName, Expr *pExpr)
{
int rc = SQLITE_OK;
if( pExpr ){
>>>> if( (pExpr->op!=TK_ID) && (pExpr->op!=TK_STRING) ){
rc = sqlite3ResolveExprNames(pName, pExpr);
if( rc==SQLITE_OK && !sqlite3ExprIsConstant(pExpr) ){
sqlite3ErrorMsg(pName->pParse, "invalid name: \"%s\"",
pExpr->u.zToken);
return SQLITE_ERROR;
}
}else{
pExpr->op = TK_STRING;
}
}
return rc;
}
