Help with Option Explicit

[Richard]

I am using Access 2000 I complied the below code and recived the following
error: Compile error: Variable not defined. If I compile with just Option
Compare Database I get no error, But if use Option Compare Database Option
Explicit I recive
Compile error: Variable not defined.

Richard,

Option Explicit means you have to explicitly dimension variables in each
routine before use.

As such add the line

Dim strSql as string

after your on error line.

Using option explicit is the best option, as it prevents mistyping names
etc... and ending up with wierd coding faults.

Thank you,

it compiled. 1 question not having this "Dim strSql as string" effect the
operation of the update query? I would think it would.

Richard,

I wouldn't think so. It just means without Option Explicit you could have

strSql = "Select..."

and the next line

Docmd.runsql strCql

and Access would try and do it, but strCql is nothing.

Stop your code in debug mode and copy strSql into a query, and have a closer
look at it there if the sql isn't working correctly.

Just to add my 2 cents to the other responses, Date is a reserved
Access/VBA/Jet word and should not be used as a field name.
For additional reserved words, see the Microsoft KnowledgeBase article
for your version of Access:

I went back and renamed my date fields to dDate but I have a combo box set to
field list I use for searching. Now in the drop down I have dDate ? how do I
change it to Date without changing the table again?

I'm not sure I understand your question.
Wherever you have a reference to the field [Date] in your database you
need to change that reference to [dDate], both in VBA and in Access
(Control Source,s Record Sources, SQL, etc.)
In Access, if you do indeed need to refer to the Date() function, not
[dDate], then manually reset that code back to Date().

If your code is in VBA, you could use Edit + Find to search for all
instances of dDate and then change just the ones which should be
Date() back to Date.

Fredg,

I use a small search form (popup) that has a combo box and a text box. The
combo is set to field list, the user can select fields to search such as
"date" in the text box they supply a string i.e. (12/1/2007) then press
search.. Well my field name in the combo has changed to dDate. I don't want
the user to see dDate in the drop down. Would it be an alias like ddate=date?
Sorry for my lack of knowledge.

There is nothing wrong with having the field named dDate and having
the user select that.
Note: If this was a concern for you, before you changed the name of
the field from Date you could have changed it to "SaleDate" or
"TheDate" or "ServiceDate" or some other more meaningful name so the
user knows what that Date field refers to.
Then your combo box would simply refer to "SaleDate", as it should.

It's still not too late to change the field name again to something
more meaningful.

 

[Richard]

Thank you for your help, I am taking your advice, and your right its not to
late to make changes.
