So, I've been doing doing reading on Append Queries and Nulls. I have the following SQL statement
INSERT INTO tblTestResults ( EnrollmentID, TestType, Result, CompletedDate, BoldFace )
SELECT tblEnrollment.EnrollmentID, tblTests.TestsID, [Forms]![frmHome]![subfrmTesting]![txtResult] AS Result, [Forms]![frmHome]![subfrmTesting]![txtCompletedDate] AS CompletedDate, tblOptionsBF.OptionsBFID
FROM tblEnrollment, tblOptionsBF, tblTests
WHERE (((tblEnrollment.EnrollmentID)=[Forms]![frmHome]![EnrollmentID]) AND ((tblTests.TestsID)=[Forms]![frmHome]![subfrmTesting]![cboSelectTest]) AND ((tblOptionsBF.OptionsBFID)=IIf(IsNull([Forms]![frmHome]![subfrmTesting]![cboSelectBF]),0,[Forms]![frmHome]![subfrmTesting]![cboSelectBF])));
Basically what I'm trying to say is that if the cboSelectBf is Null, then leave it null for the the append query or at least leave it blank. If it isn't, use the value that cboSelectBF has according to the combo box selection.
In my Accounts table I have a field called Status. This field is populated by single letters. A=Active, P=Paid and so on. I have a status (R) that is occasionally used. It won't show up in my crosstab queries since we currently do not have an account that is in R status. How can I get my crosstab to show the R status as having 0?
I've been struggling with a problem and I hope one of you can please help.
I created a crosstab query that displays group names on the vertical axis and dates on the horizontal axis. I use a Count for the values. I use a pop-up dialog to get parameters for the dates (between... and), which are organized as Quarters. The query works fine and I can insert it into a report, which also works fine... with one problem. The dates only work when the date parameters request a year (4 quarters), and only work when each quarter has at least one entry. (Only work = I get an error message when one or both of these conditions are violated.)
Sometimes, I want to look at less than a full year, but when I use parameters for three or fewer quarters, I get an error. Same thing if I request a quarter that doesn't have any data. I assume the solution is to convert Nulls to Zeros and have wrestled with both Nz function and IIf, but have not been able to convert the values. I get the correct values in the quary's dataset if they are numbers, and blanks if no data, but no zeros anywhere. I also don't know how to make my report flexible or dynamic, so I can limit the number of quarters if I only want to look at a specific quarter or quarters (less than four).
Any ideas? Thank you so much for your time, and, Happy Holidays!
hi Guys, I have been looking at different post and checking Microsoft help files as well, but still can't seem to fix this problem.
I am having 2 tables. The first table is connected to a form for viewing and entering data, and in the second table i am just copying 3-4 fields from the first table.
I am trying to use the insert statement to insert records in the second table, and everytime i click on the "Add" button to add the records i get the following error "MS access can't append all the records in the append query ... blah blah blah"
However if i close the form and reopen it, and goto the record (as it is saved in the first database) and now click on the add button to add the fields to the second table/database, it works.
(value=0 AND name <> HOT) OR (value=Null AND name <>HOT)
I also have some records (4 specifically) that have a name = nullvalue. When I run this query it picks out all the records with a name, and skips HOT(which is correct), but skips the nulls which I also want to include. Can someone help me in finding the reason for this error?
I already posted this problem in the query section, but got no where with it... here is the problem now...
I have a form with three combo boxs - cboStatus - cboFunder - cboResource on my form. Depending on what you chose as an option the subform, which is based on a query will show the data with the chosen criteria.
Only the Status field is a required field, so there are lots of nulls in the funders and the resource fields.
In the all the fields I have "ALL" or "*" as an option.
So in the criteria in the query I use this...
Like fCboSearch (forms!form name!combobox)
This calls up this function...
Public Function fCboSearch(vCboSearch As Variant)
If IsNull(vCboSearch) Or vCboSearch = " " Or vCboSearch = "*" Then fCboSearch = "*" Else fCboSearch = vCboSearch End If
End Function
This works great to show me all the records or just records with a certain criteria selected, BUT BUT BUT I cannot get it to show my the NULLS, they are no where to be found. How can I change this to show me NULLS??
I have a table which records are appended to in batch format. I would like to update a column called batch number for newly appended records with the Max of that column + 1 but I keep getting errors such as "operation must be an updateable query". Anybody have any suggestions. Mind you I am not doing this in VB or SQL formats, I use the query design format. Thanks, Jim
So, I have two tables that, cut down, look like this:
Table1: Code budget 100 5 110 7 120 3 150 6
Table2: Code actual 100 4 110 9 130 2 150 1
I have another table that is all the codes plus a description.
I thought I was being clever because I realised that there are items in Table1 that do not appear in Table2 and vice versa. I need a query that is, in effect, Table1 minus Table2.
I linked all three tables via “code”, created my query with the minus calculations and thought it had worked.
One problem. Where there is a “code” in one table but not in the other, the query puts a blank or “null” into that field. Then the minus calculation gives, say:
null - 2 = null
I’m used to Excel where:
blank - 2 = -2
Is there any way to get round this please? This must be a common problem, no?
Will someone look at my option group in my form (frmcustomer) and help me figure out why the option group selections for existing records nulls out (visually you cannot see which button had been previously selected).
The option group is working fine in that it is adding the appropriate selection to the record, but when you open the form up in edit mode the selection has been grayed out.
I have below table in SQL Server which i have linked to MS Access 2010.
Create table test ( col1 int not null col2 int not null )
Insert into Test values (1,2) Insert into Test values (1,'')
Now when i link the table to access database and open up the table i dont have any issues with that. I tried to copy the test table data from access table and paste it to another access table which is linked to sql server with same schema structure thats when it says "You tried to assign the NULL value to a variable that is not a variant data type"..Its treating the blanks as NULLS when copy/paste the records from one table in access to another.
Hi! I want to add two columns a and b. However, there are rows in which EITHER a OR b is NULL. This should be handled as if the cell would be zero. Is there any way besides filling in 0s in the tables?
I tried SELECT a, b, IIF( a = NULL, b, IIF(b = NULL, a, a+b)) AS c FROM
I'm using Access 2010 and I'm a novice with databases.I have a table that contains water flow readings taken 4 times a day from multiple wells. I am trying to create a select query that will generate the daily average of the 4 flow readings.
Also, my table also has several 0 values and NULLS meaning the well was turned off - I want to exclude the zeros and nulls when I average. How to average these numbers? Do I need to restructure my table?
I have a text field like, 11242010, and I need to be able to convert it into 3 int fields, day, month, year. I am trying to do this in a query and have create the following three;
DateD: IIf([DATE] Is Not Null,(CInt(Left(Right([DATE],6),2)))) DateM: IIf([DATE] Is Not Null,(CInt(Left([DATE],2)))) DateY: IIf([DATE] Is Not Null,(CInt(Right([DATE],4)))) Time: IIf([TIME] Is Not Null,[TIME])
When I have a value of Null, i keep getting #Error, I think when it's null.
In some cases I create pass-through queries and use these in an Append or Make-table query to bring data locally.
All is well and fine until source data changes and the pass-through query runs too long and times out.
If needed, I can extend the timeout value in the Parameters of the pass-through query no problem, but when I try to open the Append or Make-table query in Design view to do the same, the pass-through query is first triggered and then throws the timeout, and I cannot access the Design view of the Append or Make-table
Is there a way to open an Append or Make-table query in Design view without invoking the source query?
I want to 'append' individual records from 2 tables and place in an archive table or within another database, whichever is the best option. I then want to be able to 'delete' the relevant records from one table.
The tables are tproperty and trents. This property paid rents but has since been sold. Therefore it no longer belongs in the database, however client wishes to keep details of the property/person/and rents paid in past, for any future ref. These tables are linked in relationships to tlessee and tbilling. I've read books/notes/looked on here for inspiration and the right direction! If I choose 'append' which seems pretty straight forward then a 'delete' query, how do I choose only one record? Is a make-table onto a different database a better option? It would appear that the whole table is copied over? Can't understand the issue about auto-numbers being copied over? Do I have to use an append/delete query for each individual property that's ever removed? I'm at a loss! :) Thanks
I have a database that contain foreclosure records. I'd like to create a query that will ask for a date and all records that are LESS than the date will be moved to a different table.
I'd also created an icon on my form and I'd like to attach this query to it.
Please how can i use a procedure to create a query, then append the content of the query to a table (am using MS Access Project)? i did it in Microsoft acess database but now i need it on Microsoft access Project beacuase am transfering to SQL server. Thanks
Now i want to create an append query that will add in table ZALGA fealds PROIZ_I, TIP_I, DN_I, KOS_A, KOS_I by critera if TIP_A = TIP_I AND DN_A = DN_I then calculate KOS_Z = KOS_I - KOS_A?
I am building a database to hold information of training courses and staff that have requested or completed the training course.
I have built a form which the team leaders can use to request training for their team, basically when the form opens up it asks for team name and training session and then appends the names and training session ID to the main table. This then allows the team leader to tick the "request training" tick box which updates the table for each member they request trainig for. They would then send this using a custom command button which is linked through outlook.
The problem I am encountering is that if they were to selct the same team and training session again it would then append the same data to the table and this would create duplicate entries.
How can I set it up so it appends only once and then any other time the same data is selected by team leaders it would populate the form with the existing date rather than appending the same data.
Dear all, I have a trouble to run the append query. It is failed due to the key violations. Could you please help me how to solve this problem? Many thanks. Bich
Any assistance someone can give me with this append querry issue is appreciated.
I have a table called tblRoleAssignments that has three fields RoleAssignmentID (PK), RoleprofileID & ApplicationrightID. It looks something like this.
my append query will write new records depending on the RoleprofileID's I entered, for example If I run my append query on the above list I get the following output
My problem is when I run my append query I want it to enter a specific value in the role profile ID column (taken ideally from a field on a form that will be loaded) so instead of the query entering a zero it writes to the table a vaule I want. Below is how I want my append querry to write the data if I wanted the RoleprofileID to be set to 35.
