I have a query in which I select multiple values. To create my form.
The results look like this :
the last Column [Candidat Nom] is a drop down list with an other query (lets call it Query 1) that select my drop down list values.
The selection is good and is what I'm looking for. Except I get the same value for all lines when they need to be different.
To simplify
let's take the following exemple
I have the following candidate that wants to join for the following job (Represented with their ID).
As we can see 2 candidates wants job N° 12. and 1 candidate for each other job.
What I get
All candidates are listed for every job.
What I want
What I actually did
is I put the following query (Query 1) on my column.
SELECT T_SALARIE.SALARIE_nom & " " & T_SALARIE.SALARIE_prenom AS Candidat Nom
FROM T_EMPLOI INNER JOIN (T_SALARIE INNER JOIN (T_SALARIE_EMPLOI LEFT JOIN T_STATUT_EMPLOI ON T_SALARIE_EMPLOI.SALARIE_EMPLOI_statut_id = T_STATUT_EMPLOI.STATUT_EMPLOI_id) ON T_SALARIE.SALARIE_NNI = T_SALARIE_EMPLOI.SALARIE_EMPLOI_salarie_nni) ON T_EMPLOI.EMPLOI_identifiant = T_SALARIE_EMPLOI.SALARIE_EMPLOI_emploi_identifiant
WHERE (((T_STATUT_EMPLOI.STATUT_EMPLOI_statut) Like "*valid*" Or (T_STATUT_EMPLOI.STATUT_EMPLOI_statut) Like "*décidé*") AND ((T_EMPLOI.EMPLOI_entreprise_id)=1));
This gave me the result I want but with the issue I mentioned previously (Same result for each line)
So
I thought I needed a new Criteria.
I added one, where It's going to select the candidate when the two "emploi ID" of my actual table (Shown before) and the one helping me select the candidates are equal.
With the following query:
SELECT T_SALARIE.SALARIE_nom & " " & T_SALARIE.SALARIE_prenom AS Candidat, T_SALARIE_EMPLOI.SALARIE_EMPLOI_emploi_identifiant
FROM T_EMPLOI INNER JOIN (T_SALARIE INNER JOIN (T_SALARIE_EMPLOI LEFT JOIN T_STATUT_EMPLOI ON T_SALARIE_EMPLOI.SALARIE_EMPLOI_statut_id = T_STATUT_EMPLOI.STATUT_EMPLOI_id) ON T_SALARIE.SALARIE_NNI = T_SALARIE_EMPLOI.SALARIE_EMPLOI_salarie_nni) ON T_EMPLOI.EMPLOI_identifiant = T_SALARIE_EMPLOI.SALARIE_EMPLOI_emploi_identifiant
WHERE (((T_STATUT_EMPLOI.STATUT_EMPLOI_statut) Like "*valid*" Or (T_STATUT_EMPLOI.STATUT_EMPLOI_statut) Like "*décidé*") AND ((T_SALARIE_EMPLOI.SALARIE_EMPLOI_emploi_identifiant)=[R_Select_COMOB]![ACTION_identifiant_emploi]));
But I keep on getting the following pop up that asks me to enter a Job ID
So how can I make the query for each line compare and select the right values?
I hope I was clear in explaining. If not please let me know so that I can add more details.
Thank you !
Thanks to your help and specially #June7 for his propositions, I found a solution regarding my problem :
I added a criteria to select values based on JobID that I wasn't selecting in the first hand.
And then based on the column (jobID) select the values needed
here is my final query :
SELECT
[SALARIE_nom] & " " & [SALARIE_prenom] & " (" & [SALARIE_NNI] & ")" AS Salarié, T_SALARIE_EMPLOI.SALARIE_EMPLOI_salarie_nni, T_SALARIE_EMPLOI.SALARIE_EMPLOI_id, T_SALARIE_EMPLOI.SALARIE_EMPLOI_emploi_identifiant
FROM
(T_STATUT_EMPLOI INNER JOIN T_SALARIE_EMPLOI ON T_STATUT_EMPLOI.STATUT_EMPLOI_id = T_SALARIE_EMPLOI.SALARIE_EMPLOI_statut_id) LEFT JOIN R_Select_Salarie ON T_SALARIE_EMPLOI.SALARIE_EMPLOI_salarie_nni = R_Select_Salarie.SALARIE_NNI
WHERE
(((T_SALARIE_EMPLOI.SALARIE_EMPLOI_emploi_identifiant)=[Formulaires]![F_COMOB]![ACTION_identifiant_emploi]) AND ((T_STATUT_EMPLOI.STATUT_EMPLOI_statut) Like "*validé*") AND ((T_SALARIE_EMPLOI.SALARIE_EMPLOI_Entreprise) Like "*RTE*"));
And Then to update my values for each line. I added a VBA code that requery on input.
Private Sub ACTION_Candidats_P_Enter()
ACTION_Candidats_P.Requery
End Sub
With that my problem is solved.

I have two tables first table called TFile contains two columns: FromCity and ToCity.
They will have different values but from one column of the second table (TCity) and specifically from the column called CityName.Second table name TCity they have two column : IdCity AND CityName.
My problem I need to display data for two columns they got from second table FromCity and ToCity with inner join for two times.
I use this code to do that:
SqlCommand comm = new SqlCommand("select * from TFile " +
"inner join TCity AS A ON TFile.FromCity = A.IdCity " +
"inner join TCity AS B ON TFile.ToCity = B.IdCity " + " WHERE " + "TFile.Name", con);
Then display data to users as:
SqlDataReader srd = comm.ExecuteReader();
if (srd.HasRows)
{
while (srd.Read())
{
//FromCity
TextFrom.Text = srd["CityName"].ToString();
//ToCity
TextTo.Text = srd["CityName"].ToString();//=======================here problem
}
}
In the first line of the data display I can get the name of the city but if I repeat that in the second line it will just repeat the data. Here problem.I can't use a different name to access the second query instead of the field name CityName.This is the name of the field in the second table for which I display the names of the cities.
How can I access to data in this query:
"inner join TCity AS B ON TFile.ToCity = B.IdCity
So if I access to it then can display second data in this line:
TextTo.Text = srd["CityName"].ToString();
How can solve this problem ?
I bet you need to create field aliases to differentiate between values from the multiple joins on the same table. By the way, please make sure you protect yourself from "SQL injection" when using these types of queries. If you don't know what "SQL Injection" is then please take some time to look it up.
"select FromCityName=A.CityName, ToCityName=B.CityName, * from TFile "
And
//FromCity
TextFrom.Text = srd["FromCityName"].ToString();
//ToCity
TextTo.Text = srd["ToCityName"].ToString();//=======================here problem
I'm using MS Access
The SQL below updates the CurrNumTees field in the Parent tblContact records with the number of tblTorTee records that have an end date (which is not the ultimate effect I am aiming for, but I provide it as a starting point.
UPDATE tblContact
INNER JOIN tblTorTee ON tblContact.ContactId = tblTorTee.TorId
SET tblContact!CurNumTees = DCount("[tblTorTee.EndDate]",
"tbltortee","Torid = " & [ContactId]);
I need to update the CurrNumTees field with the number of records in tblTorTee that do not have an EndDate, in other words, that field is blank. I’ve tried using WHERE and HAVING and IS NULL in various combinations and locations, but without success. Could you help point me in the right direction?
The MS Access COUNT function does not count nulls, so I think you have to do this in two stages.
Firstly create a query like this:
SELECT TorId, IIF(ISNULL(EndDate),1,0) AS isN
FROM tblTorTee
WHERE EndDate IS NULL;
And save it as QryEndDateNull
Now you can run an Update Query like this:
UPDATE tblContact
SET tblContact.CurNumTees = DSUM("IsN","QryEndDateNull","TorId = " & [ContactID]);
Saving calculated data (data dependent on other data) is usually a bad design, especially aggregate data. Should just calculate when needed.
Did you try the IS NULL criteria within the DCount()?
UPDATE tblContact Set CurNumTees = DCount("*", "tblTorTee", "EndDate Is Null AND TorId = " & [ContactId]);
I need to write a LINQ TO XML query, which queries two XML files exported from Access database tables. The original Access DB query looks like this:
SELECT
(
[TableB].[Code] Is Null,[TableA].[Code],
LCase(Left([TableA].[Code],1)) & ":" & [TableB].[code]
) AS Code,
Trim
(
[TableB].[Description] & " " & [TableA].[Description]
) AS Description
FROM TableA LEFT JOIN TableB
ON TableA.Code = TableB.SubProduct;
When I convert it to LINQ to XML, I have the problem of the right part of the left join is not available. My LINQ look like this:
Dim results = _
From a In TableA.Descendants("Product")
Group Join b In TableB.Descendants("Product")
On a.Element("Code").Value Equals b.Element("SubProduct").Value Into leftJoinGroup Group
From p In leftJoinGroup.DefaultIfEmpty
Select New With
{
I DON KNOW HOW TO WRITE IT
}
Both tables have the column named "Code". However, the variable TableB seems to be unavailable inside my Selectclause. I only have a and p available so I can't get the Code from TableB (b). How should I do that?
I just started using linq myself and ran into this issue last week. This was very helpful for me http://msdn.microsoft.com/en-us/vstudio/bb688088.aspx but here is an example of how to perform a left outer join in vb.net http://msdn.microsoft.com/en-us/vstudio/bb737909#lojoin.
In your example tableB is being stored into leftJoinGroup which your selecting from using p. To get values from tableB you will need to select from p and since your trying to concatenate the columns from both tableA and tableB, I would check if tableB record is null.
Dim results = From a In TableA.Descendants("Product") Group Join b In TableB.Descendants("Product") _
On a.Element("Code").Value Equals b.Element("SubProduct").Value Into leftJoinGroup = Group _
From p In leftJoinGroup.DefaultIfEmpty() _
Select New With { _
.Code = If(p Is Nothing, a.Element("Code").Value, String.Format("{0}:{1}", Left(a.Element("Code").Value.ToLower(), 1), p.Element("Code").Value)), _
.Description = If(p Is Nothing, a.Element("Description").Value, String.Format("{0} {1}", p.Element("Description").Value, a.Element("Description").Value))}
Here is an example of your code above, I didn't tested it. I've used this code when joining datatables not xdocuments. Sorry if this isn't clear this my first post here.
I'm trying to make a query which has the same field in table A & table B. Then table B has the same field as table C. I want to left join all tables on table A. Is this possible? If yes, how close is my code to doing it?
Try
objConn = DBAccess.GetConnection
strBlder.Append("SELECT ")
strBlder.Append("FLD_NM, DATA_TYPE_CD, XML_PATH_TX, UPDT_USER_ID_NR, DOC_TMPL_FLD_ID_NR ")
strBlder.Append("FROM ")
strBlder.Append("LLC.[LLCW10_DCTMPFLD_TB] LEFT JOIN LLC.[DataMapTool_FieldMapping] ")
strBlder.Append("ON LLC.[LLCW10_DCTMPFLD_TB].DOC_TMPL_FLD_ID_NR = LLC.[DataMapTool_FieldMapping].DocumentTemplateFieldID ")
strBlder.Append("& LEFT JOIN LLC.[DataMapTool_FieldMapping] ")
strBlder.Append("ON LLC.[DataMapTool_FieldMapping].FieldMappingStatusID = LLC.[DataMapTool_FieldMappingStatus].FieldMappingStatusID ")
strBlder.Append("ORDER BY FLD_NM ;")
dsData = DBAccess.ExecuteDataTable(objConn, CommandType.Text, strBlder.ToString())
'execute non query - takes sp name
The error you are getting(after removing the &) is because LLC.[DataMapTool_FieldMapping] is repeated and thats a problem. Instead of your from clause try something like:
FROM (LLC.[LLCW10_DCTMPFLD_TB] LEFT JOIN LLC.[DataMapTool_FieldMapping] ON LLC.[LLCW10_DCTMPFLD_TB].DOC_TMPL_FLD_ID_NR = LLC.[DataMapTool_FieldMapping].DocumentTemplateFieldID)
LEFT JOIN LLC.[DataMapTool_FieldMappingStatus] ON LLC.[DataMapTool_FieldMappingStatus].FieldMappingStatusID = LLC.[DataMapTool_FieldMapping].FieldMappingStatusID
Note that the LLC.[DataMapTool_FieldMapping] is referenced in the first join and then only the .FieldMappingStatusID field is referenced in the second join. Your initial query would have been trying to add the same table to the query twice without giving it an alias which confuses the query analyzer.
Basically the new from clause will attach the first two tables together then attach the third table onto the result of the first join.
Looks good to me, but there is that strange & before the LEFT JOIN LLC.[DataMapTool_FieldMapping] ... take that out.
I've created a basic Combobox Filter Sort that sorts through Company Regions for my company (Acronyns mostly) we refer to these as AOR's or Area of Reference. After defining your AOR, it limits the next combo box to show only Countries in that specific AOR, hense the Filter Sort. But, my problem is - when it displays the countries after selecting an AOR - It displays ALL RECORDS in that specific country, instead of just 1 country listing.
Basically, It isn't grouping my countries - and when I select "Totals" which normally gives me only unique results, this doesnt work.
My question, How can I re-write this code to include a Group By?
My Code:
Private Sub cboRegion_AfterUpdate()
' Region -> Country
Dim sManagerSource As String
sManagerSource = "SELECT [FullEmail].[AORID], [FullEmail].[ID], [FullEmail].[Country] " & _
"FROM FullEmail " & _
"WHERE [AORID] = " & Me.cboRegion.Value
Me.cboCountry.RowSource = sManagerSource
Me.cboCountry.Requery
End Sub
My SQL statement looks like this (It's got Group By in it, but it doesn't GROUP)
SELECT FullEmail.AORID, FullEmail.ID, FullEmail.Country
FROM FullEmail
GROUP BY FullEmail.AORID, FullEmail.ID, FullEmail.Country
HAVING (((FullEmail.AORID)=1));
Thanks in advance for reading through!
The previous answer is correct, except with a having clause you need to use aggregates... so just use where.
SELECT Country
FROM FullEmail
WHERE AORID=1
GROUP BY Country;
That should fix you up. When you use HAVING it looks at what you've selected, since you didn't select AORID, it didn't know what to do.
