Filtering for single quotes

Jennifer Methlie · May 29, 2012

I have a form with several large text fields for users to input instructions. If they use a single quote (apostrophe) I get an Oracle error. How can I allow the users to user the single quotes in these fields? It's impossible to tell them not to.

Thanks! (and I'm not a programmer so please be gentle).

Use SelectSql() and paramaters for all database interaction. It is the only way that is simple and safe.

Step 2: Ask Metatsorm to add parameters to all the database functions...

The error comes when they try to save the form. The text field is tied to a local variable. Can you clarify the parameter I should be setting? Thanks!

You are not updating a record directly? If these are Process Variables, that sounds like a massive bug. I shall try on our Oracle installation today to confirm.

On field exit, I've tried adding

Replace(Local.memAction, "'", "''", 0)

But still get the same error. Anyone have a working solution? Thanks!

We have tried this on several of our Oracle installations, and it works perfectly. Can you confirm that this is a standard variable, and that you are not executing any SQL?

Could you also confirm the version?

The fix was to NOT use the "InsertRows" from the toolbox with a simple Insert statement but to use the "Code Activity" and enter something like:

{

Mstm.SelectSql(new MetastormDefault(),@INSERT INTO YOUR_TABLE

(Column1,Column2)

VALUES (@p1, @p2)",

new QueryParameter("@p1",Local.Variable1),

new QueryParameter("@p2",Local.Variable2)

);

}

Now the user can use as many apostrophes as they want.
