In your above code you can't use a variable in the query string for the specified DBLink. Bind variables are only allowed in places where an expression are allowed, and they will never be interpreted as a database object (table name, column name, function name, etc). However, since you appear to be in complete control of the DBLink through your chained if statements it would be safe (in this instance) to concatenate the DBLink into your query strings:

QUESTION

How do I use parameters in VBA in the different contexts in Microsoft Access?

Asked 2018-Oct-04 at 07:48

I've read a lot about SQL injection, and using parameters, from sources like bobby-tables.com. However, I'm working with a complex application in Access, that has a lot of dynamic SQL with string concatenation in all sorts of places.

It has the following things I want to change, and add parameters to, to avoid errors and allow me to handle names with single quotes, like Jack O'Connel.

It uses:

DoCmd.RunSQL to execute SQL commands
DAO recordsets
ADODB recordsets
Forms and reports, opened with DoCmd.OpenForm and DoCmd.OpenReport, using string concatenation in the WhereCondition argument
Domain aggregates like DLookUp that use string concatenation

The queries are mostly structured like this:

There are many ways to use parameters in queries. I will try to provide examples for most of them, and where they are applicable.

First, we'll discuss the solutions unique to Access, such as forms, reports and domain aggregates. Then, we'll talk about DAO and ADO.

Using values from forms and reports as parameters

In Access, you can directly use the current value of controls on forms and reports in your SQL code. This limits the need for parameters.

You can refer to controls in the following way:

Forms!MyForm!MyTextbox for a simple control on a form

Forms!MyForm!MySubform.Form!MyTextbox for a control on a subform

Reports!MyReport!MyTextbox for a control on a report

Sample implementation:

QUESTION

Secure, extensible database with dynamic prepared statements

Asked 2017-Oct-19 at 16:47

Problem: My task is to create a database to hold information about various products and to create RESTful api to serve and manage this information. But the client doesn't know exactly what all information they will need on these products, so the database is likely to have new columns and tables added later on to accommodate new product properties. My question is about producing a database that will readily accept these changes and constructing queries that can fetch products securely based upon product properties that don't yet exist with little to no modification.

Proposed Solution: I have a test database setup with the following structure.

My first reaction to your SQL is that you really need to learn how to use JOIN in SQL. The join operation is really fundamental to SQL and relational data. Using only subqueries in lieu of JOIN is like using another programming language, but refusing to use a while() loop. Sure, you can do it, but why?

ANSWER

Answered 2017-Aug-07 at 13:31

Why is it safe?

PostgreSQL (and about any other DBMS) will first compile the statement with the $1 in place, and only then will use the actual value provided by the user. So whatever is in the value cannot be interpreted as a part of the statement. In other words, using the parameter separates code from data.

Why do I need a procedure for this?

In most cases, you don't. What you really need is a mechanism that separates code from data, i.e. the parameter. In most languages and DB connectivity libraries nowadays there is a parameterized query support present, which allows you to write queries with placeholders (such as ?) and provide data through a separate parameter.
