Modules & VBA :: How To Extract Recordset From Subform Into Recordset Object
Aug 14, 2015
Special situation: The SQL Server Linked Server across the country is linked to a Read Only Oracle DB. This data pull works perfectly and populates the Subform.
The problem is that Oracle can take 3 to 6 seconds to retrieve the single record depending on the network traffic through a small pipe.
The code below shows the RecordSource for the SubForm. clicking on a list box supplies the value. Then 3 to 6 seconds later, the subform populates.
The actual Recordset for this Recordsource is needed to conduct Validation on each field. Normally this would be on SQL Server, I might just create a Recordset Oject and run this SQL statement again in 1 milisecond. In this case, it will probably take an additional 3 to 6 seconds. Avoiding another lengthy round-trip to Oracle would be prefered.
Goal: How does one grab, clone, or other wise reference the existing recordset for the SubForm?
Note: Immediate Window - One single field can be returned quickly
There are 48 fields that need validation - is there a way to reference the entire recordset?
Immediate Window during Break Mode:
? me.fsubsrNavSHLBHL("NavSH_QQ")
NESE ' this is the correct value for the current recordsource
Set a breakpoint right after the line:
fsubsrNavSHLBHL.Form.RecordSource = "Select * from vsrNavigatorSHLBHL where Well_ID =" & txtNavWellID.Value
Immediate Window:
? me.fsubsrNavSHLBHL.Form.RecordSource
Select * from vsrNavigatorSHLBHL where Well_ID =91229
I am in the middle of creating a function that populates two unbound text boxes on a form and then uses those unbound textboxes in a query (Total of 3 unbound text boxes - 2 are populated from this function). The saved query object is working fine when I manually execute it (after the unbound text boxes have been populated). However, when I go to set the same query to a recordset I am getting the "Too Few Parameters. Expected 3." error message.
In the saved query I used the build function to use the unbound text boxes as part of the where clause. Below is the code I am trying to execute:
PHP Code:
Public Function Test()Dim db As DAO.DatabaseSet db = CurrentDbDim rst As DAO.Recordset Dim DtBegin As String''FInd the Begin dtstBegin = DateAdd("q", -1, DateSerial(Year(Date), (DatePart("q", Date) - 1) * 3 + 1, 1)) Dim DtEnd As String''find the end dateDtEnd = DateAdd("Q", DateDiff("Q", 0, Date) - 1, 0)
[Code] ......
The unbound text boxes are populated before the query is set to the recordset.
I want to write a email where there are 2 or 3 different ordernumbers for same email, i want to include the email in the mail part as single column table. how to do it? also can i use result of one recordset for other recordset?
I've been trying : double click a field in a subform and paste the query results into excel. I already have good code to paste in the recordset, but this recordset must reference a control value in a subform.
The query works and shows the proper results manually, but when I run the Sub it throws a "run-time error 3061: Too few parameter. Expected 1."
I can't seem to set the parameters right. Tried EVERYTHING--except the RIGHT thing.
I've been banging my head against this problem for a while now and making no progress and am hoping someone cleverer than me can provide some assistance in solving it, or point me in the right direction.
Here goes....
I am working solely in the VBA environment and would like to perform an automated process that returns a recordset based on the results of a previously created recordset (assuming of course it is possible in the first instance.)
The catch is I would like to perform an INNER JOIN using the results held within a recordset. I have already achieved this by creating a temporary table (using a SELECT INTO statement) and then removing the temporary table when I am finished but find this is a slower process than I would like.
I have three tables: Table A - Fields: GROUP, NAME, DATA1, DATA2 Table B - Fields: GROUP, NAME, , CITY, DATA3 Table C - Fields: CITY, DATA3
I have the following declarations:
Dim db As Database Dim rs1 As Recordset, rs2 As Recordset, rs3 As Recordset Dim strSql As String
Set db = CurrentDb
Next, I select a specific range I am interested in. For the purpose of this example, I am only selecting GROUP values of 1,2 and 3.
strSql = "SELECT * FROM A WHERE A.GROUP IN (1,2,3)" Set rs1 = db.OpenRecordset(strSql) rs1.MoveFirst
Now, for each record returned in the query above, I would like to process as follows:
The rs2 query returns the results of that query into what I though was a memory resident table referred to as "jc". (This is most likely where I am going wrong!) Using this reference, I perform another query...
And from this point I would be able to process the results (if any) that I need to....
...if it wasn't for the error: "The Microsoft Jet database engine cannot find the input table or query 'jc'. Make sure it exists and that its name is spelled correctly."
I know the table doesn't 'truly' exist as a physical object or entity within the database, so how do I reference this 'phantom' table in a query?
I am happy to provide more details if it would help solve this problem and would really appreciate any feedback that anyone has to offer.
I am adding new record into subform via recordsetclone method. The problem is that record is added but on save it does not appear in the table. If add this record manual using subform everything works. When record added manually update of the record works fine.
C 'Add Wastage value to flooring area section Private Sub Wastage_AfterUpdate() Dim rsFlArea As DAO.Recordset Dim Wastage As Double Dim Item As String Set rsFlArea = Me.OrderFloorAreaEdit.Form.RecordsetClone
My form respectively subform has a couple of problems related to the recordset as it is available in VBA.
The mainform contains material data, the subform contains the components of that material and a quantity, while the components are materials themselves. The subform's control source is an SQL statement created by the query builder.
Everything worked fine before i replaced the material-selecting combobox in the continuous subform by a textbox and a button. That button leads to another (dialog) form with some filtering options, which in turn returns the number of the selected material. This material gets inserted into the textbox. To this point it works fine.
But when i enter a quantity before i selected a Material, i get an error message after selecting the Material: This Action was Cancelled by an Associated Object. This happens while executing the following VBA Code on click of the material selection button (exact position commented in code):
Code: Private Sub cbuSelectComponent_Click() ' Select component Dim SQL As String Dim rs As Recordset DoCmd.OpenForm "Material Selector Dialog", , , , , acDialog, "Dialog" If GLB_selected_mat = -1 Then 'cancel
[Code] ....
I've found the following Microsoft KB Article: [URL] ..... In their example code they use:
' Restore text box value to the original record contents ' in this case, that is NULL datDataCtl.UpdateControls
I assume this is the relevant part, but i have no DataControl (what's that?) and neither found an UpdateControls method in the subform object.
The second error, "no current recordset", occures when i edit an existing component line in the subform that has been added right before (also using the same event and code as mentioned above). If i close the form after adding the component and open it again, it's no problem.
Hi guys, I'm a bit confused: I know that opening a bound form will bring down the whole recordset. But if I create a parametered query as the recordsource, will it still bring down the whole recordset first and only afterwards cut down to the records matching the parameters?
Example: I have a clients table with 5000 clients on a backend mdb, and my client lookup form in my frontend mdb. If I open the form looking for just client "Jim Jones" (via the parameter query), will Access bring down all 5000 clients from the backend to my frontend first, and only then seek out "Jim Jones" before discarding the rest of the recordset?
For if this is true then this whole Access business is rather unsuited for networks, even a small one. I hope you guys prove me wrong.
So far I had several Subforms which would open in a mainForm depending on the combo box value. My combo box values were exactly the same as subform names so that I can easily change subform.recordsource = combo.text and it would show the proper form. Now, I'm thining, instead of having all those forms, I could have only one form and just changing it's recordSource property with the sma combo box, but this time, combo.value would be the name of the SQL string that the form needs to take as it's recordSet.
What I want to know is, if this will work at all, and if it would, where do I have to set my vars...in the Form_load()?!:confused:
I have a main form which has a subform control in it. when the main form is opened the sub form control contains a list of events in a sub form (a summary view), for the person selected in the main form.
I want to change the subform to a different one which shows the whole event when i click in a field on the subform, based on the event i clicked in. ( i can do it by opening a new form but not with a new subform)
I can make the form change using the following code:
How it works: You search for a User, and then you search for a Serial.Now, what if I want to edit the table? (inside the subform, the results). I added an openRecordSet, and Parameters, but I still get the error saying that Recordset cannot be updated.Why? I opened and sent parameters but still fails.
I have a form with a continuous subform whose RecordSource is a predefined query. There are a number of controls on the main form which allow for various filtering on the subform / query and a command button to export the data to Excel.Because I want to export exactly whatever the user has filtered using the form, I take a clone of the subform recordset and pass that as a recordset object to my export function.
I've just noticed, however, that a couple of the fields in the Excel spreadsheet are always blank, even though the corresponding records on the subform show values? I can't figure out why; there is nothing unusual or distinctive about these fields (2 x Text and 1 x Date/Time) other than the fact that the contents don't seem to copy? I do get the field names - just no data for them?
The data is visible in the subform, and when I run the query on its own, the fields are populated in the returned dataset as well? So why aren't they included in the RecordsetClone?
from a table with fields userID and Date (in which any userID has multiple records with different Date values, and other fields) i have built a select query based on Date = one specific value. can anyone give an explanation (for beginners), through a sample code, that expands the query recordset so that the new recordset includes all records per userID that qualified in the prior recordset? below is an example. thank you!
Table with records: userID / Date u1 / d1 u1 / d2 u2 / d1 u2 / d2 u3 / d2 ... 1st Select Query (where Date = d1): u1 / d1 u2 / d1
Desired 2nd Query based off 1st Query (where ?): u1 / d1 u1 / d2 u2 / d1 u2 / d2
I have two tables that have the exact same fields. In table1 I have records that need to be UPDATED into table2. I tried an Update query and out of 600 records only half of those got updated. In my update query I joined tbl1 and tbl2 by Location (LOC) I checked for Nulls, Blanks, spaces, you name it. I can't figure why they all didn't get updated. I created a SQL query and go the exact same results. Ideally, I would like to create something in VBA to do this. I do not have any forms linked to these tables. In all I have about 600 records and 15 different fields that need to be updated. My example is only for one field.
sql example below. Which is the Access Sql in the Query
I have a form with a query set up as the record source. If there are records in this query, the form will display. When the user clicks a button, if there is another record in this query, the form displays the next record. When it gets to the EOF, it should close this form, but EOF is not being recognized (I run debug and it says it's false when the button is clicked)? I get run-time error '3201' after I click the button twice.
I know for a fact that there are 2 records in this query. So once I click the button on the 2nd record, the form should close.
Code: Private Sub SelectTblMyMedButton_Click() Dim db As DAO.Database Dim rs As DAO.Recordset Set db = CurrentDb() Set rs = db.OpenRecordset("qryMedDataSelect", dbOpenDynaset)
I have learned the basic looping technique for going through a record set from the following link. I need to know if my logic is on the right track. URL...
My question is a followup to a thread that was opened on this forum: URL....I want to do the following:
1) Use record set looping technique to fix a variety of incorrect naming conventions to a standard format 2) Update the table (or create a new table) from the updated record set values. (Is my logic going to update the table selected in the code I used to dimension the record set or will I need to do something else to make the changes available for other tasks after record set is closed ? After the naming conventions are fixed this data will be available for excel automation that I am working on and posting questions on another thread in this forum. HAHA I'm going code BANANAS) 3) rs.fields![fleetlocation] is used so many times, how can I make this a variable (what do I dimension the variable as?) 4) Use an AND statment with an if statment (how to do this with correct syntax)
Code: sub loopandfix() on error goto errorhandler: strSQL = "tblUnionQueryResults" 'table was created from a union query but has inconsistant naming conventions for the fleet location name
I am trying to open a child recordset but keep getting Error 424 "Object required".
Dim rstEmails As DAO.Recordset2, DBS As DAO.Database, rstFile As DAO.Recordset2 Set DBS = CurrentDb Set rstEmails = DBS.OpenRecordset("Beldenemails") Set rstFile = rstEmails.Fields("email").Value 'Error 424 here End Sub
Is there a possibility to use a shorter code for extracting one field from one record, than opening a recordset, getting the field, closing it and setting the recset to "Nothing" again? I'm doing this multiple times in my code and it seems a bit too much for what it's supposed to do.
Code: sql = "SELECT tblAdFlgDaten.* FROM tblAdFlgDaten WHERE (((tblAdFlgDaten.AuftrID)=" & ABAuftrID & _ ") And ((tblAdFlgDaten.Schritt)=2))" Set RSnap = dbase.OpenRecordset(sql, dbOpenSnapshot) If IsNull(RSnap.Fields(2)) Then ... ... End If RSnap.Close Set RSnap = Nothing
How does one go about removing a recordset from a ListBox?
I have a list box that I want to toggle between using a query and an ADO RecordSet to populate the values.
Once I set the listbox .RecordSet property to the ADO.Recordset, I can't remove the values displayed in the listbox when I assign a query to the .RowSource property.
I suppose I can turn the .RowSource query to an ADO Query but I am being lazy and don't want to rewrite the query as a T-SQL query.
I previously thought the list box was pulling data from the .RowSource query but I realize I was wrong.
Is it possible to create a record set from a list box?
I have two list boxes list1 (customers) the can transfer records to list2. I want to take all records from list2 and use it to open a report, using customer id as where clause in my docmd.openreport statement.
As I am moving through my code, I'd like there to be a pop-up box which asks the user to choose from a list of dates. This list of dates only resides in a filtered recordset in the background.
Once the date is chosen, then my code continues onward..I know I could make some sort of pop-up form, but I'd rather not have to go in a design all that just for a list of dates...
1) Is there such a thing as a dropdown list on a Input box?
and even if there isn't...
2) Is there a way I can bind the column in a recordset to a dropdown list?
Im still struggling with working with recordsets.What i want to achieve is to loop through a continuous form recordset, Using the OrderDetailFK from the record set and the OrderDetailPK in the OrderDetail Table
Looking at the Status FK in the OrderDetail Table. IF the OrderDetail Status = 2 then i want to make the textbox enable property = False. I have made the bellow SQL string which is placing all the criteria i just need to link it into a recordset?
Code: mySQL = "SELECT [StatusFK] FROM [tblOrderDetail] WHERE [OrderDetailPK] = " & rst!OrderDetailFK & " AND [StatusFK] = 2 "";"""
I'm trying to assign the result of an SQL query to a variable using VBA in Access. The query returns a value but the variable which it is assigned to has a value of Nothing. Here is the code snippet:
Dim queryReturnID As String queryReturnID = "select dbo_tbl_SupplierReturn.ReturnID from dbo_tbl_SupplierReturn" & _ " where SupplierID = " & lstPOHdr.Column(1) Debug.Print queryReturnID Dim RecordSet1 As DAO.RecordSet Set RecordSet1 = CurrentDb.OpenRecordset(queryReturnID)
