Hi

I did a search on MSDN for "sql bind variable". Here is the result page:

http://search.microsoft.com/default.asp?qu=sql+bind+variable&boolean=ALL&nq= NEW&so=RECCNT&p=1&ig=01&ig=02&ig=03&ig=04&ig=05&ig=06&i=00&i=01&i=02&i=03&i= 04&i=05&i=06&i=07&i=08&i=09&i=10&i=11&i=12&i=13&i=14&i=15&i=16&i=17&i=18&i=1 9&i=20&i=21&i=22&i=23&i=24&i=25&i=26&i=27&i=28&i=29&i=30&i=31&i=32&i=33&i=34 &i=35&i=36&i=37&i=38&i=39&i=40&i=41&i=42&i=43&i=44&i=45&i=46&i=47&i=48&i=49& i=50&i=51&siteid=us/dev

Looks like some articles might help.

An: Multiple recipients of list ORACLE-L Betreff: RE: How to change VB code to use bind variables?

Hi Jared,

Thanks for the suggestion. But I went to www.microsoft.com, clicked on support and searched on the words
bind variables oracle visual basic

After a dozen Internet Explorer Script errors I got a bunch of links with names like 26jbkjakjbmon

That one led to a blank page. Others led to articles that didn't even mention bind variables. And I thought Metalink was bad.

Does anyone have a link that goes directly to an article?

Thanks,
Jay Miller

Check on the MS support site. There are several articles detailing how to do this.

Hi,

In checking my v$SQLArea I recently discovered that there was an often executed SQL statement that was not using bind variables. I tracked it down
to a VB front end and asked the development group to modify the code. They asked me how to do it.

Not being a VB programmer I said I had no idea but would try to find out. Here's an abbreviated version of the code. It's the sAcctId that seems to be causing the multiple executions. Anyone know how this can be rewritten to use bind variables? Can it be done from VB or do we need to transfer the
code to PL/SQL on the back end?

Private Function GetSQL(ByVal sKey As String, _

                        ByVal sAcctId As String, _
                        Optional ByVal sAcctNum As String, _
                        Optional ByVal sWhereAnd As String)
Dim sConnect As String
Dim sSql As String
Dim oWsiLibData As WSILib.CDisplayData
Dim rsCustomer As ADODB.Recordset
Dim lCustId As Long
Dim sCustId As String

Select Case sKey
.......
.......
Case "accountinfo":

                 sSql = "SELECT a.id, a.account_no, a.type, a.title1, 
a.title2,
a.title3, " & _
                    "a.inventory_date date_opened, a.last_modified_date
last_change, " & _
                    "rc.description rebatecmsn, " & _
            sSql = sSql & " account_info.fetch_email(" & sAcctId & ") 
email
"

            sSql = sSql & "FROM account a, status s, usa_wh_tax u, fund f, "
& _

                    "stock_commission_codes sc, cmsn_rebate_codes rc,
account_kind ak "
            sSql = sSql & ", dual " 
            sSql = sSql & "WHERE a.status_id=s.id and
a.usa_tax_code=u.code(+) " & _
                    "and a.fund_id=f.id and " & _
                    "a.s_stk_cmsn_code=sc.code(+) and
a.cmsn_reb_code=rc.code(+) and a.kind_id=ak.id " & _
                    "and a.id =" & sAcctId

            sConnect = sConnectWSI

            GetSQL = Array(sConnect, sSql)
