Edit Current Object's SQL in MS Access through VBA - sql

I am using MS Access 2013 trying to edit the SQL of the current query that is being displayed on the screen. I can get the name of the current query using qName = Application.CurrentObjectName however the current query is not saved, nor do I want it to be saved.
I know that using something like below, I can get the SQL of a saved query and modify that query.
Dim qd As QueryDef
Set qd = CurrentDb.QueryDefs(qName)
qd.SQL = "Select Customers.ID From Customers"
However, the query that I want to modify is not saved, but rather just being worked on. What I want to do is access the SQL which is visible in SQL view, read that into a variable, and modify it. I am not sure how to proceed and would appreciate some help. (What I have tried is summarized above.)
(In case you are curious. The queries I am working on may be new or may be being modified from saved queries; saving could overwrite something which I am not yet finished with/is not working, thus causing more issues.)

If your unsaved new query is open in Datasheet View, you can retrieve its SQL like this:
MsgBox Application.Screen.ActiveDatasheet.RecordSource
However if you want to modify that SQL within its current query window, I can't help you.

Cannot view the SQL portion of a query in ACCESS?

I am currently working on a project of replacing our old access database queries, but on one of them I am not able to view the actual SQL View.
Does anyone know a way to force the view or to export it somehow?
Error causing problem:
The SQL statement could not be executed because it contains ambiguous outer joins.
Note that I can view the Design View without issue but when I right click on the tab and select SQL View is when I get the error.
I did attempt what #LeeMac mentioned below but same error occurs:
EDIT:
This question is not like Ambiguous Outer Joins?
The OP on that question can actually see and edit their SQL.
My issues is that I cannot see or edit the SQL as the SQL View wont open.
Try executing the following VBA code from the Immediate Window (accessible using Ctrl+G) in the VBA IDE (open the IDE using Alt+F11):
?CurrentDb.QueryDefs("YourQuery").SQL
Replace YourQuery with the name of your query.
This should print the SQL code which comprises your query - you can then analyse the SQL to determine the cause of the error.
It's odd this error would arise when merely viewing the SQL content of the query definition.
It makes me think that the query is perhaps referencing a crosstab subquery which is actually the cause of the error, but which needs to be evaluated in order for MS Access to determine the columns available when viewing the design of the query in question.
Try this:
hit ctrl-g, and from immediate window type in this:
saveastext acQuery,"Name of query","c:\test\mysql.txt"
Access ordinarily doesn't allow you to save invalid queries, so it's strange you somehow got into this situation in the first place.
If you can copy the query, you can easily get to the SQL by changing the query to a passthrough query, either through the GUI or through VBA:
Dim q As DAO.QueryDef
Set q = CurrentDb.QueryDefs!Query1
q.Connect = "ODBC;"
Debug.Print q.SQL
Passthrough queries are not validated, so you can freely read and write anything you want as SQL in it.
Note that this is irreversible when done through VBA. You can only change it back to a normal query once you made the SQL valid again. If you do it through the GUI, you can just not save it, though.
I had this problem and the issue was that i had a subquery that calculated fields but did not actually have a table in it. for example it would calculate first and last day of last month which is 2 calculated fields, then it was the first query in a series of queries that were built off it and the last one wouldnt resolve sql as original poster indicated also gave the ambiguous join message as well as query needs input table (which was that first subquery). i put a table with 1 record in it but didnt use the record and it worked.... so it just a needs a table in it.

MS Access keeps on breaking my queries

I wrote a query in MS Access which I was able to run successfully. However whenever I head back to Design View in MS Access 2010, it kindly corrects it for me into SQL that doesn't even work!
Here is my original SQL (which I ran successfully):
SELECT [AssetTypeCounts].DELIVERED_IDENTIFIER,
[AssetTypeCounts].DELIVERED_SOURCE,
Switch([AssetTypeCounts].TYPES<1,"Missing",
[AssetTypeCounts].TYPES=1,"Correct",[AssetTypeCounts].TYPES>1,"Conflicting") AS STATUS
FROM (
SELECT DELIVERED_IDENTIFIER, DELIVERED_SOURCE, Sum(IIf(Len(PRODUCTTYPE)>0,1,0)) AS TYPES
FROM (
SELECT DISTINCT DELIVERED_IDENTIFIER, PRODUCTTYPE, BILLINGCODE, DELIVERED_SOURCE
FROM AprilUsageFile) AS "DisctinctAssetIdBySource"
GROUP BY DELIVERED_IDENTIFIER, DELIVERED_SOURCE
) AS AssetTypeCounts;
After I go back to Design View I get an error:
The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.
I didn't even get a chance to edit the query.
Why does Access keep changing my query?
Can I disable features where MS Access is changing my queries?
try to create a new query by printing in immediate window:
Dim qDef As DAO.QueryDef
Set qDef = CurrentDb.QueryDefs("NameOfBrokenQuery")
Debug.Print qDef.SQL
As a general rule never open SQL queries in designer mode, because access will always change parts of it and then it will be harder for your to change it.

query criteria based on form field

So I have a query where I select a field and set the criteria so that it only selects records based on the current value of a particular field in my form. The criteria looks like this.
[Forms]![FORMAL_CERT_REVIEW_CHECK_FORM]![REVIEW_CHECK_ID]
Pretty simple stuff. But I am running into the issue where when I run the query I get the prompt that says I need to enter a value. I know that this usually happens when you set the criteria to something that may not exist or you spelt it incorrectly, but I have checked all of this and it seems like everything looks fine.
I was curious if there is something I could be missing, like a property on the field or something that I have not thought of.
When you directly open a query which includes a reference to a form control, Access is able to retrieve the query's parameter value from that control on the open form.
However, if you attempt to use the same query as the source for a recordset, Access does not resolve the query parameter from the open form.
For example, this is my query, qryREVIEW_CHECK_ID.
SELECT f.id, f.datetime_field, f.some_text
FROM tblFoo AS f
WHERE f.id=[Forms]![FORMAL_CERT_REVIEW_CHECK_FORM]![REVIEW_CHECK_ID];
With FORMAL_CERT_REVIEW_CHECK_FORM open, everything works fine when I open the form directly ... like this for example ...
DoCmd.OpenQuery "qryREVIEW_CHECK_ID"
However, using that query as the source for a recordset triggers error 3061, "Too few parameters. Expected 1."
Dim db As DAO.database
Dim rs As DAO.Recordset
Set db = CurrentDb
Set rs = db.OpenRecordset("qryREVIEW_CHECK_ID")
The workaround is to open the recordset from the QueryDef object. And include Eval() so that Access will resolve the parameter using the parameter's name.
Dim qdf As DAO.QueryDef
Set qdf = db.QueryDefs("qryREVIEW_CHECK_ID")
qdf.Parameters(0) = Eval(qdf.Parameters(0).Name)
Set rs = qdf.OpenRecordset
Your description doesn't specify whether your form is a simple form or a sub-form. I came across the same issue and realized that I was only entering the sub-form's name in the criteria.
Assuming that you have FORMAL_CERT_REVIEW_CHECK_FORM sub-form under PARENT_FORM, your criteria should read
[Forms]![PARENT_FORM]![FORMAL_CERT_REVIEW_CHECK_FORM]![REVIEW_CHECK_ID]
I hope this helps you or others. Used in Access 2016.
I have experienced this on several occasions after making a design change to the form. There is no fault with what you have done - it is an access corruption. The solution is to copy the database to another file name, delete your forma and query, compact and repair, and then import the form and query again. This normally solves the problem. It appears importing it resets the internal references allowing the form to work as it should.
Doesn't seem like this was ever solved, and I just came up with the same issue. I solved it by deleting the form and recreating it. Like you I had, [Forms]![MyForm]![ID] and out of no where it started asking for user input for the criteria on my listbox query. Making a new form and copying over the fields seems to have fixed it.

(VB / ACCESS / CR) Filter VB Crystal Report based on Access Form

Before I get to the question, here is an overview of what is going on.
Access
A form that has a ComboBox that selects a JobId
Crystal Reports
A Report that calls info from several tables, all based on the JobID
VB
A Form (Using the Crystal Reports Plug-In) that shows the Report outside of the Crystal Reports Designer app.
My Problem
I need the report displayed in VB to be filtered to the job chosen in the Access ComboBox.
Update
I have my Database linked to VS2012, and that works fine without any issues. I can pull info from a Table easily. What I need to do is link the ComboBox from an Access Form to VS2012 to filter the Report.
I hope that makes my question clearer.
Update 2
I was able to figure out how to create a SELECT Query based on the value of my ComboBox inside of Access, so I should be able to use that to access the Value I am looking for, however I still need to know how to use that value as a filter for CR...
One possible solution would be to create a saved Select Query in Access that replicates the query in CR, and name that query [JobReport_base]. Then, create another saved Select Query in Access and name it [JobReport_current]. Add some code to your Access form that updates the .SQL property of the [JobReport_current] query to return just the records for the selected [JobId], something like
Dim qdf As DAO.QueryDef
Set qdf = CurrentDb.QueryDefs("JobReport_current")
qdf.SQL = "SELECT * FROM JobReport_base WHERE JobId = " & cbxJobId
Set qdf = Nothing
Then update your Crystal Report to pull the data from the [JobReport_current] query instead of the individual tables.
Multiple solutions. In your case, the simplest ones are the following:
There is this 'sqlQueryString' property of the report that you could update by directly updating the string.
You could also add a parameter (let's call it 'PAR_yourCombobox') to the report. When accessing the report in your VB code, just set the value of your parameter to the value on the screen. as far as I remember, it should look like:
yourReport.parameterFields(i).addCurrentValue yourForm.controls("yourCombobox").value

MS Access query with dynamic from statements

Ok this is vexing me. I have a query I created with an in statement in the from clause. What I am looking to do is have a global variable populate that from statement. Example
Select *
Form query1 in <Global Variable filename>
What is going on is I link to a file that has hundreds of linked table and queries in it. My database only has a few select queries and link table to different database. I did not want to re-build all the queries and linked table is my database. The issue is the file with all the links changes name once a month. I just want to read a text file with the current name of the database in it so I do not have to keep changing my queries every time the database name changes. Also this has to a query since I have other queries using the externally linked query.
I have one suggestion, but its pretty kludgy.
Rewrite the query on the fly with VBA call
Private Sub update_qtest()
Dim db As Database
Dim qd As QueryDef
Set db = CurrentDb
Set qd = db.QueryDefs("qtest")
qd.SQL = "SELECT * from query1 in " & g_file_name
End Sub
As I said, it's kludgy, but I don't think there's a way to pass the from clause as a parameter.
Another way to do this would be to just use the same file name each month so you wouldn't have to change anything in your Access app at all. You could easily code copying the file to the standard name over top of the previous copy (you'd have to delete it before copying, of course), which would retain the history.
