General :: To Know If Same Value In The Field Already Exists
Aug 14, 2013
I have a table called 'maintable'. It has 5000 plus entries of employees with different fields. Every Employee has unique ID. One field is date of birth (dob). Normally more than one person can have the same date of birth. A form (maintable1) is created to enter data into this table.
In order to avoid duplicate entry of the same employee again with all his data, I wish to know if the same date of birth (dob) which is being entered now already exists for any employee to verify if the employee being entered is the same, if not then I can enter the data of new employee with the same date of birth.
So basically when I will enter data in a form for the dob field, if the value is the same, then a message that entry already exists, then the 'maintable' may open highlighting the same date of birth entry, so it can be verified if the same person is not entered again.
I have a table with several thousand records. Each record as a path field that indicates a specific file that is associated with a given record (not just a directory, it identifies a specific file). I'm pretty sure that most of them are correct but I've seen and been cleaning up paths that have had typos in them or were otherwise not setup correctly. Is there a way that I can generate a report or a list of some sort that would tell me exactly which file paths exist and which ones don't? or even just the ones that don't.
I'm starting to automatically save PDF copies of certain reports in predetermined locations. I need to copy a file to a particular directory (based upon various criteria), but if the directory does not exist, I want to create the directory on the fly first. Otherwise I will just proceed with the copy.
I'm sure there is a DOS command to do this, but I can't find it.
I have one table let's call is table1. It contains about 5 columns with standard employee data with about 10,000 rows of data containing about 1,150 employees. All employees have multiple rows of data. There is one column titled JOB. I need to pull all rows of data for each employee ONLY if there is at the minimum one value for the employee in the JOB column. I do not want to pull employees that have no values in the JOB column. They can be excluded from the query.
Example of all record for one employee. I need to pull all rows of data ONLY if the employee has a value in the JOB column.
Name EE_ID JOB CAT EFF_DATE

I'm trying to use DCOUNT to check to see if a date exists and if it does then i can cancel the input. The code im using is as follows however its returning datatype mismatch.
Code: If DCount("[pick_date]", "tblPicker_Stats", "[pick_date] = '" & txtPickDate & "'") > 0 Then MsgBox "Statistics for this date already exist", vbOKOnly, "Error" End End If
I am storing values of pictures and the location of them in a table, this works fine!... using OpenRecordset. The problem is that when the function is called to store the information, it just keeps adding the same values of each file in the folder over and over again in a word "Duplicating" the information.
I have tried various methods using the OpenRecordset, but cannot seem to find the correct manor of applying the code.
Below is the function I have for storing the data...
Code: Public Sub GetFilesNamesFromFolder(strFolderPath As String) On Error GoTo ErrorHandler Dim objFSO As Scripting.FileSystemObject Dim objFolder As Scripting.folder Dim objFile As Scripting.File
I am trying to achieve the following - I want to query a table to see if a record exists with a particular field blank. If so, I would like to prompt the user for data.
In real world terms, when assigning an item to a user I would like to first make sure that the item is not already assigned to somebody else. I have 4 fields, UserName, Item, IssueFrom, IssueTo. So when an item is assigned to a user, the first 3 fields are populated and the IssueTo remains blank, until that item is assigned to somebody else.
At the minute I have nothing in place to prevent a user from assigning the same item to multiple users and having multiple records for the same item in the table.
Tables join using fQSRegno. Scenario is Tbl Individual contains all the members info.Tbl Point contains point given to members who attend courses. Problem is when I created a query...
I have 2 identic tables: T1 and T2 which contain only one field NR.
T1 contains the data: 1 2 3 4 5 6 7 8 9 10 11 12
T2 contains the data: 5 6 7 8 A B C D
I want to select all the records found in T1, but not found in T2. So, I wrote the following SQL query:
SELECT T1.NR FROM T1 WHERE NOT EXISTS (select T2.NR from T2);
Unfortunately, this query doesn`t return any record. And the strangest thing is that the query:
SELECT T1.NR FROM T1 WHERE NOT EXISTS (select T2.NR from T2);
have the same effect like:
SELECT * FROM T1,
I mean it returns all the records of T1. I mention that the query was written in Access. What I have to do? Can anybody help me? What solutions do I have? I need a query, not a VBA code!
I need to make a query that only selects data that is in another query/table.
I have tried to do this using a query with IN criteria as follows.
SELECT fldOne,fldTwo,fldThree, FROM tblOne WHERE (((tblOne.fldOne) In (Select fldOne from tblTwo)) AND ((tblOne.fldTwo) In (Select fldTwo from tblTwo));
But that isn't working. Any ideas as to why?
I think that the answer might be using the EXISTS reserved word, but I don't know how.
How can I do an existence test on a table in my Access MDB in a script. The job is to determine if a temp table exists, and if so, then to drop the table.
What syntax would I use to accomplish this in form event code?
Hi, I have the following problem which I hope someone can help me with:
I have a form which is used to enter data into a table. One of the fields is 'Code'. I want the form to check when data is enetered into this field is it already exists, ie if the code is already present in the 'code' field in the table, and if it is it should give a warning message, if not then continue as normal.
Any help would be greatly appreciated, thanks in advance!
I have a form used to enter new contacts. I would like to insert a query or macro that would automatically to see if the name (first and last) already exists in the table to which this form is attached. If the name exists, I want to open the existing record and add information to it. If not, I want to enter the information as a new record.
I keep getting the error message "Table TempMsysAccessObjects already exists" when I try to compact/repair my database. The only help I've found in the MS knowledge base just says to delete the table. I keep deleting it, but it keeps coming back. I've tried the decompile cmd line option, no change. Do I need to just rebuild this db, or what?
the problem is that sometimes the table doesn't exist... Instead of trapping the error code, is there a way I can check to see if the table exists? If it doesn't I'll simply skip this step of my code and move on.
I have tried the attached code from a previous post http://www.access-programmers.co.uk/forums/showthread.php?t=98727&highlight=table+exists but some of the code doesn't work on Microsoft Access Project. Does anyone have any ideas how I would amend this code so that it works?
I have created a query/report that meets all necessary criteria except that it contains multiple TYPEs per employee. This isn’t an issue unless one of the TYPEs is ‘W’. As TYPE ‘W’ supersedes all other TYPEs, any others that meet the other criteria should no longer be reflected in the query/report.
I know this can be done i MySQL and with SQL Server but is there a way to drop the table but check if it exists first in Access before running a query ?
I have 2 tables TKYOKUMD01 and TTOKUKMD01. So Im supposed to get the records that aint found by this query in the TKYOKUMD01 table: SELECT a.* FROM TKYOKUMD01 a, TTOKUKMD01 b WHERE a.KYOKUSYOCD & a.BUNSITUCD = b.KYOKUSYOCD & b.BUNSITUCD
Easy right? All I have to do is use NOT EXISTS Right? So I did, hence: SELECT * FROM TKYOKUMD01 WHERE NOT EXISTS (SELECT a.* FROM TKYOKUMD01 a, TTOKUKMD01 b WHERE a.KYOKUSYOCD & a.BUNSITUCD = b.KYOKUSYOCD & b.BUNSITUCD)
No records returned, so maybe all is good and happy in their relationship interconnected world. So just to check I inputted 99999 for KYOKUSYOCD and 9 FOR BUNSITUCD in the TKYOKUMD01, now clearly it should appear right? Coz its there, on the blessed SQL code. BUt the I ran it, BAM, no results? Whaja...juhh...
Please please please help me with this, is there something wrong with this statement coz Im pretty sure I was right :(
Oh and I have 24,000 records in the TKYOKUMD01 table and 18,000 records on the TTOKUKMD01 table, weird eh? Every one in the 24K table is in the 18K table? Like, what I said, Whaja...juhhh....
On my Form, I want to have a query look at one specific field for a number (1). If the number is found then I would like to have the query do basic subtraction on two other fields. (one from each table)
What I have so far is one unbound text box with the following, =IIf(tblDaStrategy!DaNumber=1,(tblDaStrategy!DaTar get-tblDaReport!DaActual1))
Simply put, if one field has the number one in it, then take the other two fields and subtract (ex. 100-75) to display 25.
It's not working. I keep getting the #Name?
Update: I think I got it. I went back to square one and made a master query that contains the data from both tables. Then I bound one of the forms to the query. I updated my IIF statement and poof. It seems to be working. Now, where's the Asprin and my pillow?
Update 2: Bummer, now my magical 25 is in place but now my form is locked tight. Guess I need to consider abandoning this concept and simply producing a report with the 25 on it. Unless someone out there has a better idea.
Hi, i have a simple query but for some reason it's not working.
Let me get to the point. 2 tables - table1(id,txtfield1) table2(userid, idfield) idfield contains id so foreign key (although hasnt been set up as that yet)
Aim: select all fields from table1 where table2 doesn't contain them.
hello all, i've written this query and all was working fine, but.... i added the Where IN statement and no it runs really slow. i have tried using the Where exists option but couldn't get it working.
As i understand it this is probably the worst query to run on a jet database as it contains subqueries, select Disinct and a Where statement.
any /pointers to speed it up?
thanks all
