Queries :: JOIN Expression Not Supported
Dec 18, 2013
I am using vb.Net to connect to an access db. In access 2010 this query works fine, but in vb.Net, it errors with 'JOIN expression not supported'.
Code:
sql = "SELECT Boxes.Box, Boxes.CustRef, Boxes.Customer " &
"FROM (Requests INNER JOIN [Request Boxes] ON Requests.[Request no] = [Request Boxes].[Request no]) INNER JOIN Boxes ON [Request Boxes].Box = Boxes.Box" &
"WHERE (Requests.[Request no]) = '" & item & "' " &
"AND ((Boxes.Customer) = '" & customer2 & "'))"

I am trying to execute the query below with multiple left joins because of the data I am trying to get back. The weird thing is sometimes it work and then sometimes it gives me a join expression error. It seems that access strangely removes brackets around the ON clauses. However even when I put those brackets back in this query it isn't working. why this query isn't running or why the brackets disappear in Access 2010.
SELECT Patients.[First Name] & " " & Patients.[Surname] AS Fullname
, [Clinic Patient].[MYMOP ID]
, NZ(MYMOPs.[MYMOP Date], [Clinic Patient].[First Appointment]) AS [MYMOP1 Date]
, MYMOPs.Completed AS [MYMOP1 Completed]
[code]....

I've been toiling with the issue of WHERE clauses on the "Right" side of Left Joins. I'm aware that you need to use JOIN ON......AND.... rather than JOIN ON....WHERE.... if the WHERE relates to the Right Hand table.
I've even got an example in my DB where the above works, but now am struggling to use the same theory for other tables. Therefore, I went and created two Mickey Mouse tables to test the logic but am getting an error.
I have
Table 1 with one field called Field 1 - values A, B, C
Table 2 as follows
Field 1.....Field 2.......Field 3
A.............100
C.............200..........XXX
I hoped to have a query that finds all records on Table 1 and records on Table 2 where Field 1 matches on the two tables and Field3 = XXX
My SQL is
SELECT Table1.Field1, Table2.Field1, Table2.Field2, Table2.Field3
FROM Table1 INNER JOIN Table2 ON Table1.Field1 = Table2.Field1
AND Table2.Field3="XXX";
but I get Join Expression not supported
What am I doing wrong?
Thanks
Andrew

I have 5 different tables that are all linked with foreign keys. When I made my fifth table and linked it to my primary key like I had with the other tables I got the Join expression not supported error.

Using Access 2010 and ODBC connections to pull data from 3 sources (SQL Server 2008, a customized Documentum application, and Windows AD accounts). Problem is user_login_name is sometimes recorded as lowercase, sometimes as propercase, and sometimes as uppercase depending on which table or source being used. For example, lowercase would be "abcd123", propercase would be "Abcd123", and uppercase would be "ABCD123". I thought I could just wrap each join comparison in the From stmt in the query(s) with the UCase() function, but Access doesn't like that.
How can I convert or cast the various user_login_names within the FROM join statement to be the same text case so joins will pull correct data?

I don't quite understand this error message, and therefore cannot begin to fix it. One of my forms will not open except in design view because of a "Type Mismatch in JOIN expression" error. Can someone please tell me where to look to fix it? Thanks.

Hi, got a slight problem. As part of an ASP website I'm trying to insert into two linked tables in an access database using SQL. Standard SQL syntax woiuld be:
INSERT ALL INTO tblParent(name, Address) Values ('Dave','Home')
INTO tblChild(age, phone) Values ('35','1234567');
Thing is, does Access SQL support the INSERT ALL INTO statement? I keep getting syntax errors and I can only guess it might be this. if so, how do you make multiple table inserts into Access through SQL?
Cheers, Lol

the databases functionally normally with no issue. I have several databases one for each project and they are all having this issue. It doubles the size of the DB after the failure. This seems to tell me that the crash is just after the DB is ready to rewrite the database compacted. I run C&R about every 2 weeks and have a spread sheet tracking DB size prior to and after C&R. The compactions run from about 1% to 15% the norm seams to be 4% to 6%. The size of the DBs run from 65KB to 100KB.

Ok, I have having a problem joing these two queries. Can anyone please help me out here. These are the results of my two queries:
These are the values in the A1 field of QueryA

IPP GT1
IPP GT2
KALG F5
KALG F6
KWIN C6
MUJA 1
MUJA 2
MUJA 3
MUJA 4
MUJA C5
MUJA C6
MUJA D7
MUJA D8
These are the values in fields A1 and X1 in QueryB:
COCKBURN 86.83

MUJA C6 89.01
MUJA D7 86.22
MUJA D8 84.65
How can this be done. I need this in another query. I have tried the join statements, but I get errors every time. Thanks in advance.

I have three queries that I would like to make into one query, but I'm having trouble. How do I combine the three queries into one? The three queries are below. The qryGetMaxChapter3 is the one that I will use, i.e. it is built on qryGetMaxChapter2, and qryGetMaxChapter2 is built on qryGetMaxChapter1.
qryGetMaxChapter1
SELECT tblCourt.CourtID, tblCourt.ID_Number, tblCourt.ActionDate, tblCourt.Chapter
FROM tblCourt
WHERE (((tblCourt.CourtActionsID)=1 Or (tblCourt.CourtActionsID)=2));
qryGetMaxChapter2
SELECT tblCourt.ID_Number, Max(tblCourt.ActionDate) AS MaxOfActionDate
FROM tblCourt INNER JOIN qryGetMaxChapter1 ON tblCourt.CourtID = qryGetMaxChapter1.CourtID
GROUP BY tblCourt.ID_Number;
qryGetMaxChapter3
SELECT tblCourt.ID_Number, tblCourt.ActionDate, tblCourt.Chapter
FROM tblCourt INNER JOIN qryGetMaxChapter2 ON tblCourt.ID_Number = qryGetMaxChapter2.ID_Number
WHERE (((tblCourt.ActionDate)=[MaxOfActionDate]));

Dear friends
I maintain a document database wherein query is generated for individual status like approved, pending & due. approved and pending are generated through "like text*" in status filed. But for due it is separate query using >=Now() in date field.
I want to join these two queries and result should be in one query as :
Approved document
Pending Document
and from balance document using Now query - due.
One report is attached which will help understand - blank yellow field requires due query.
Please help

I am having a problem trying to join two queries. The first query, which is called qry_Planned_By_Month comes from a table (tbl_planned) that captures budget planning information. I created an expression in this query called SumOfPlanned. It takes the sum of all common budget line items (BLI) and is broken down by month.
The second query is called qry_Actuals_By_Month, which comes from a table (tbl_actual) that captures the actual amount spend against each BLI. Again, I created an expression in this query called SumOfActuals. It takes the sum of all common BLIs broken down by month.
Problem: I am trying to create a third query where I can compare planned versus actual. The formulas that I am using to do this are accurate. However the result set contains duplicate data. For example, I may have three entries on the planned side (March, June, and December) and on the actual side for the same BLI, I only have data in February. It displays the February data three times (because it is in the same row as the March, June, and December data.
Is there anything I can do? Thanks very much in advance. URL

An affiliate sent us a table of email addresses, one per record. We need to find which ones already exist in our master table. Our master table contains an email field but it may contain MULTIPLE email addresses separated by semicolons. How do we create a query (or queries) which tell us which email addresses already exist somewhere in our master table?

I tried doing a search but couldnt find the i needed.
Category_name Sku
cars 1
Trucks 1
Bikes 1
Phones 2
Tablets 2
Hats 3
and what i need to is something that will link all sku 1 category names in a new field with a | divider and then all the sku 2 category names together with | as a divider and so on. the amount of categories is different for every sku.
so it looks like this
Joined_categories sku
Cars|Trucks|Bikes 1
Phones|Tablets 2
Hats 3
And if this is easy enough, its not that important though but to delete duplicate category names when it transfers them across to a new field joined together.

I have my main linked table VI, and 4 of VI's fields are to be filtered in a query.
To do so, I have 4 very very tiny local tables (less than 20 records) called respectively "soff", "skus", "warr" and "typ", in which the user will only put what he wants in the result, and by doing Inner Joins, I filter it easily.
Problem is, doing more than 1 Inner Join slow the query so slow it's unbelievable.
If I run the query:
Code:
SELECT VI.*
FROM VI INNER JOIN SKUS ON VI.Sku= SKUS.Sku;
It runs in 0.7 seconds. It's about the same if I replace SKU by SOFF, WARR, or TYP, the query takes about 0.5 to 1.5 sec.
Now if I run:
SELECT VI.*
FROM (VI INNER JOIN SKUS ON VI.Sku= SKUS.Sku)
INNER JOIN SOFF ON VI.SOff = SOFF.Soff;
It takes either 15 seconds, or up to 100 seconds.
I tried by doing 4 successive queries, it's the same. The 1st query runs well, and then it grinds to a near-halt.
Running either the 4 queries or a query with the 4 inner joins takes me about 200 seconds, sometimes 400-500.
It's not even a hard query, VI has only almost 1mil rows, and the fields are indexed. The result is 800 rows.
If each join on VI takes 1 second, it should do 1sec+1sec+1sec+1sec, taking in account the fact that the left side of the join grows smaller at each step, it should even do something like 1+0.8+0.5+0.2, or something. Why does having these joins together, or follow each other, make things so damn slow?

I currently have two tables each containing information that I need to complete a query, however the results of suming this information is incorrect.
Below is the structure of the table, one contains more fileds than the other however the joins are on the Date and the Name fields. I have added a few dummy results to show the format
Table 1
"Date" "Name" "Times Logged In"
10/01/2013 Chris 1
11/01/2013 James 3
Table 2
"Date" "Region" "Manager Name" "Name" "Times Logged Out"
10/01/2013 Scotland Cindy Chris 1
11/01/2013 Wales Robert James 2
Query Fields
"Data" "Region" "Name" "SUM Times Logged In" "SUM Times Logged Out"
I can see what the issue is, if someone hasnt logged out there would be no entry in the table so the result query would show "Times Logged In" as X and a blank value at "Times Logged Out." However if there is a value at "Times Logged Out", "Times Logged In" is displayed again and causes the SUM calculations to be incorrect.
how do I overcome this issue though? I can do two spereate queries on the tables to produce results for Times Logged In and Times Logged Out but cant seem to create one query to display both these results in one table.
What I want is IF the date in Table 2 = Date in Table 1 AND IF Name in Table 2 = Name in Table 1 THEN take the value from Logged In and place that in a column and the value from Logged Out and place that in a column.

I have a table and a query. The first 4 fields of the table correspond to that of the query. The query does not have any other fields, but the table has 26 more fields. Is it possible to use SQL OUTER JOIN or UNION or whatever to append the data of the query to the table or do I have to go with recordsets of VBA?

I am looking to create a query using a main table and 3 related tables to produce a count of evaluations completed and evaluations passed by month (using the 3 related tables) and site location (using main table) which is joined by agent name. I have the following so far but:
Code:
SELECT
[MainTbl].Location,
Format$([Tbl1].[EvaluationDate],'mmmm yyyy') AS [EvaluationPeriod],
Count([Tbl1].[Agent Name]) AS [NoCompleted],
Count(IIF([EvaluationScore]>=0.9,0)) AS [NoPassed]
[Code] .....
But I get the following results:
Code:
Location EvaluationPeriod NoCompleted NoPassed
Location1 Month1 Tbl1.NoCompleted Tbl1.NoPassed
Location1 Month1 Tbl2.NoCompleted Tbl2.NoPassed
Location1 Month1 Tbl3.NoCompleted Tbl3.NoPassed
Location2 Month1 Tbl1.NoCompleted Tbl1.NoPassed
Location2 Month1 Tbl2.NoCompleted Tbl2.NoPassed
Location2 Month1 Tbl3.NoCompleted Tbl3.NoPassed
etc..

I'm having problems doing a left join with 3 fields. I know I don't need the 3 fields for this example to align the data but, I deal with much more than this and need this functionality.
The query object I'm looking into is named 'left join' and the sql is as follows:
SELECT Act_Base.CustID, Act_Base.Chipset_ID, Act_Base.Product, Act_Base.Qtr, Act_Base.Qty AS Shipments, SE_Base.Qty AS SE
FROM Act_Base LEFT JOIN SE_Base ON (Act_Base.Product = SE_Base.Product) AND (Act_Base.Qtr = SE_Base.Qtr) AND (Act_Base.CustID = SE_Base.CustID);
I'm expecting to see 150 units in the SE.Qty field.

And then called this join as a symbol or variable, and then have it use to select the items from these joined tables, can this be done in Access? Here is an example of a code that I created, but it has an error message saying the FROM syntax is incorrect.
Code:
SELECT firstJOIN.trainID, firstJOIN.trainName, firstJOIN.stationID, firstJOIN.stationName, firstJOIN.distance_miles, firstJOIN.time_mins
FROM (trains INNER JOIN ((station INNER JOIN lineStation ON station.stationID = lineStation.stationID)
INNER JOIN bookingLeg ON bookingLeg.startID = station.stationID or bookingLeg.endID = station.stationID )
ON trains.trainID = bookingLeg.tid) as firstJOIN
Can Access do something similar to this, in the FROM statement I joined 4 tables, because each unique fields are in each table and I have to joined them to get those fields. I called this join firstJOIN and in the SELECT statement, I list those columns in the table by calling it firstJOIN.trainID. Can Access do something like this, but syntax it differently?

I was working on an update query while joined to another table - and the error I was receiving was the query was not updatable. Er... The table that was being updated sure seemed able to be updated...
Then I wondered if the reason this didn't work was because the other table I was updating from was a query whose records were sum'd and group'd by..I ended up testing the idea by inserting the query's records into a temp table and then did the update to the target table from the temp table... which worked fine.
