I have two tables. Main table is "CompleteEmailListJuly11" and the second table is "CurrentCustomersEmailJuly11". I want to delete rows in CompleteEmailListJuly11 table that CurrentCustomersEmailJuly11 has based off email.
I've tried this following Delete example, but it doesn't do anything close to what I'm trying to do. This only shows me the ones that EXIST in the database, it doesn't show me the the list of emails that AREN'T matching.
DELETE * FROM CompleteEmailListJuly11 AS i
WHERE EXISTS (
SELECT 1 FROM CurrentCustomersEmailJuly11
WHERE CurrentCustomersEmailJuly11.email = i.EmailAddress
)
Help is greatly appreciated.
This is the query I think you need:
DELETE FROM CompleteEmailListJuly11
WHERE EmailAddress IN (SELECT email FROM CurrentCustomersEmailJuly11)
Ps: The DELETE query does not delete individual fields, only entire rows, so the * is not necessary, you will also need to "Execute" this query rather than "Previewing" or "Exporting"
If you're building your DELETE query in Access' query designer, notice there are two different modes of operation which seem similar to "go ahead and do this".
Datasheet View (represented by the grid icon labeled "View" on the "Design" section of the ribbon). That view enables you to preview the affected records, but does not actually delete them.
The "Run" icon (represented by a red exclamation point). "Run" will actually execute the query and delete the affected records.
If you already know this, my description may seem insulting. Sorry. However, it seems that folks new to Access can easily overlook the distinction between them.
You can use something like this adapted to delete
SELECT ... // complete
EXCEPT
SELECT ... // current
I am not sure exactly how it maps to delete but take a look at that.
I fond it in a similar question: How do I 'subtract' sql tables?
We can use Correlated Query to resolve the issue like
DELETE FROM COMPLETE C
WHERE EMAIL = (SELECT EMAIL FROM CURR CU WHERE CU.EMAIL=C.EMAIL);

I am trying to write a query that 1) works and 2) shows meaningful information.
However, I can't seem to complete both scenarios. Both bits of code do work to a degree. My SQL query does work by showing all the useful information a user wants but when you click the edit button it doesn't link properly so it won't allow the user to update that row. The other shows only keys and rowid but when you click edit does show the information and allows it to be updated.
So as not to get another down-voted question, I have taken pictures of each scenario to show the problem, but, ultimately, I need to show meaningful information: an id or key isn't meaningful to the vast majority of users.
Here is my code
SELECT APPLICATIONS.APP_ID, APPLICATIONS.SRN, STUDENTS.SURNAME, STUDENTS.FORENAME, APP_STATUS.STATUS, METHODS.METHOD, JOBS.JOB_TITLE, APPLICATIONS.APP_DATE
FROM APPLICATIONS
JOIN STUDENTS
ON APPLICATIONS.SRN = STUDENTS.SRN
JOIN APP_STATUS
ON APPLICATIONS.STATUS_ID = APP_STATUS.STATUS_ID
JOIN METHODS
ON APPLICATIONS.METHOD_ID = METHODS.METHOD_ID
JOIN JOBS
ON APPLICATIONS.JOB_ID = JOBS.JOB_ID;
and here are the pictures of it in action
below is the code that does not show meaningful information but does work.
select "ROWID",
"APP_ID",
"SRN",
"STATUS_ID",
"METHOD_ID",
"JOB_ID",
"APP_DATE"
from "#OWNER#"."APPLICATIONS"
If i knew how to properly use rowid i am sure this is a simple feat but i dont so if i could get any help it would be useful
//edit
who ever renamed this to Application Expression why? what i am using is Apex Application Express it was relevant information that got changed to something wrong which might make it hard for someone with a similar problem to find later.
In the second, simple query, apex can determine which table (and record) you are trying to edit.
In the first query, with the joins, it can't tell which of the five tables in query you want to edit. You probably want to have the edit link pass the primary key of the row from APPLICATIONS to the child page. You would need to build into that page any logic (lists of values etc) that map lookup tables (such as status) to the values needed in the APPLICATIONS table.
I updated a simple Access select query, adding four fields from the single table the query uses. When I then attempted to edit data in the form that references that query, Access did not allow any edits. After poking around at other possible edit rights problems I went back to the query design, and saw this:
The table CC_Tracker_1 does not exist in the database, nor is there a query by that name, as you can see in the object list:
In the design view, CC_Tracker_1 displays as an exact copy of CC_Tracker. Additionally, the four fields I added had CC_Tracker_1 listed as their table of origin.
Deleting CC_Tracker_1 from the query and re-adding the fields from CC_Tracker fixed the problem, but I'm very curious as to how this could happen.
Edit to add: This is the SQL Access generated. As you can see the alias it created isn't used anywhere in the code except in the variable list. Why it would do this is still the question:
SELECT CC_Tracker.LAST_NAME, CC_Tracker.FIRST_NAME, CC_Tracker.MRN, CC_Tracker.RIN,
CC_Tracker.SUBSCRIBER_ID, CC_Tracker.ASSIGNED, CC_Tracker.Letter, CC_Tracker.[1stCall],
CC_Tracker.CHRA, CC_Tracker.[ICP/Review], CC_Tracker.F2F, CC_Tracker.ICTCont,
CC_Tracker.ICTSheet, CC_Tracker.ICP2MD, CC_Tracker.SigPg, CC_Tracker.HTR_1st_cont,
CC_Tracker.HTR_2nd_cont, CC_Tracker.HTR_3rd_cont, CC_Tracker.HTR_Letter,
CC_Tracker.CLOSE, CC_Tracker.Comments, CC_Tracker.CHRA_Next, CC_Tracker.ICP_Next,
CC_Tracker.F2F_Next, CC_Tracker.ICT_Next, CC_Tracker_1.Final_Follow, CC_Tracker_1.BH_SA,
CC_Tracker_1.Readmitter, CC_Tracker_1.CCM, CC_Tracker.ASSIGNED_CARE_COORDINATOR, CC_Tracker.Final_Follow
FROM CC_Tracker, CC_Tracker AS CC_Tracker_1
WHERE (((CC_Tracker.ASSIGNED_CARE_COORDINATOR)=[Forms]![frmCoord_Selector]![cmbCoords]))
OR (((([CC_Tracker].[ASSIGNED_CARE_COORDINATOR])
Like [Forms]![frmCoord_Selector]![cmbCoords]) Is Null));
If you look at the SQL that is generated for the query, you will see that it has created an alias called CC_Tracker_1 for the CC_Tracker table.
Your query may need to be rewritten to exclude this alias, and any incorrect joins.
If you post the actual query generated, we will be able to help fix it.
So, basically, I have two tables called "dadoscatalogo" and "palavras_chave", with a common field, "patrimonio" which is the primary key of "dadoscatalogo".
I'm using a servlet to connect to the database with these tables, and passing a query to search for entries based on some search criteria that's defined by the user.
Now, since the user can search for entries based on information present in both tables, I need to do an INNER JOIN, and then use WHERE to search for that info. I'm also using LIKE, because the user may pass just part of the information, and not all of it.
So, to test it all out, I tried passing it a few parameters to work with, and see how it went. After some debugging, I found out that there was some mistake in the query. But I can't seem to be able to point out exactly what it is.
Here's the test query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.patrimonio LIKE '%'
AND dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
So, basically, what I'm trying to do with this query is, get all the primary keys from "dadoscatalogo" that are linked to a record with a "titulo" containing "tons", or a "palchave" containing "programming".
PS. Sorry for the names not being in English, hopefully it won't be too much of a distraction.
EDIT: Right now, the tables don't have much:
This is the dadoscatalogo table:
http://gyazo.com/fdc848da7496cea4ea2bcb6fbe81cb25
And this is the palavras_chave table:
http://gyazo.com/6bb82f844caebe819f380e515b1f504e
When they join, I'm expecting it to have 4 records, and it would get the one with patrimonio=2 in dadoscatalogo (which has "tons" in titulo), and the one with palchave=programming (which would have patrimonio=1)
As per my understanding run below query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
I am having an issue regarding repeating data in my access form, I want to be able to select a tutors name and for it to display all of the students linked to that tutor this does work however in the list view because one tutor sees many students the data is repeated (see images) Is there a SQL statement I should be using to stop this? (I am new to Access and SQLServer so I apologies if this is an obvious) Please see the images below which will make my issue clear.
I solved my problem by adding SELECT 'DISTINCT' to my SQL Statement so from
SELECT "Tutors"."PAT" FROM "Tutors";
To:
SELECT DISTINCT "Tutors"."PAT" FROM "Tutors";
I know this has been posted before but I am not sure I have got my head around the logic let aloan trying to get it into to JET Friendly Syntax.
Here is what I am trying to do
I have a bunch of records that relate to documents and I am planning on renaming the documents with GUID's however some records point to the same document here lays the problem.
Table
ID, LegacyFullPathNme, GUID, isDuplicate
my code loops through and assigns each record a GUID. then I want to update the Duplicate Documents records with the same GUID
below is my hash at it but doesn't work "Operation must use an updateable Query
UPDATE [IO Documents] a
set a.codedFileName = (SELECT B.codedFileName
FROM [IO Documents] b
WHERE b.LegacyFullPathName = a.LegacyFullPathName)
Currently use a macro to go throw RBAR
I'm a little confused on why you would do it this way since now your globally unique id column isn't unique in that multiple rows will have it.
I think a better method would be to simply create a new table from your old one with a row for each file path.
SELECT LegacyFullPathNme
INTO newtable
FROM oldtable
GROUP BY LegacyFullPathNme;
and then add the guid into the new table afterwards. (note that I didn't test that sql snippet so that might not be proper syntax but I think it gets the point across).
I believe you are looking for something like this:
UPDATE [IO Documents] SET
codedFileName = DMin("codedFileName","IO Documents","LegacyFullPathName='" & LegacyFullPathName & "'")
