WildCards Referencing Null Entries
Jun 24, 2005
I have a Qry that has a criteria of
Like "*" & [Forms]![FrmSearch![Cmbo1]
However on this field there are null field entries and even if the cmbo box is null it wont display these results.
I tood out the & [Forms]![FrmSearch![Cmbo1] section and just left the wild card and again only displayed the records where this field had an entry.
How can i get it so that when no selcetion has been made in the combo box all the records show up.
Many Thanks

Good Morning All,
I have an unbound text box on a form.
The Control Source references a text box on one of its subforms.
How do I make it return a 0 when the subform text box is null?
It seems like an if statement of some kind.
Thank you all in advance.

Hi, first of all I have to say I'm quite a noob at Access, so I apologise if my question seems stupid. :p I Googled for quite a bit looking for a solution but couldn't really get anything to work (maybe because I wasn't doing some of the possible solutions correctly?).
Anyway, I have a database with two tables, and I'm trying to make a QBF to search for data from these two tables. Quite a few of these entries have null values.
SELECT [M-Table].Firstc, [M-Table].Secondc, [S-Table].Thirdc
FROM [M-Table] LEFT JOIN [S-Table] ON [M-Table].Firstc = [S-Table].Firstc
WHERE
((([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([Forms]![interface]![TxtFirstc]) Is Null)
AND (([Forms]![interface]![TxtThirdc]) Is Null))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([Forms]![interface]![TxtThirdc]) Is Null)
AND (([Forms]![interface]![TxtSecondc]) Is Null))
OR ((([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*")
AND (([Forms]![interface]![TxtFirstc]) Is Null)
AND (([Forms]![interface]![TxtSecondc]) Is Null))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([Forms]![interface]![TxtThirdc]) Is Null))
OR ((([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*")
AND (([Forms]![interface]![TxtFirstc]) Is Null))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*")
AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*"))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*")
AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*")
AND (([Forms]![interface]![TxtSecondc]) Is Null));
This really long and tedious code was the only way I could get it to work such that in my query form, if I leave any one of the fields blank the search will still pull all the related results out, regardless of whether there are nulls in the values themselves, e.g. if I search for anything with "ab" in Secondc, it will give me all the data with "ab" in Secondc, even if there are null values for those entries in Firstc and Thirdc. Similarly for searches with the other fields.
I tried using IIF and Nz, first using IIF under Criteria, then I read somewhere that they should be used under Field rather than Criteria, but I couldn't really get it to work. Either the QBF wouldn't return any results, or it would return only those entries without null values, so if I searched for "ab" in Secondc, I wouldn't get the entries that had "ab" in Secondc but null values in either Firstc or Thirdc.
The problem with my solution is that I wouldn't be able to get it to work in another database with like 10 fields. The number of combinations would be a killer...
Is there any workaround? Many thanks! :)

I have a form that feeds information to a query which in turn sets up a report. For clarity i will list out in basic terms what I have
Input Form
- Check Box to activate/De-activate a text field [chk-active]
- Text field for a parameter [txt-Parameter]
the query has a column that has null values from the originating table. These values will be added a t a later date, but need to be queried and reported at some business intervals.
In the query criteria for this column, I have the following Criteria
Like IIF([Forms]![ReportGenerator]![chk-Active]=0, "*", [Forms]![ReportGenerator]![txt-Parameter])[/I][/I]
I have tried for the last 5 hours to figure out how to write the formula to be able to get the blank entries to show up as well but have had no luck.

I have a Membership List Table with a calculated field entitled Member Name.
The second table entitled Groups contains only 46 records each of which has up to 30 Fields also containing member names.
I Have written a query to establish which of the members from the single field of the first table do NOT featured in any of the fields and records of the second table. In the Query Design View I have listed 'Member name' from Table 1 followed by all the relevant member fields from Table 2, carrying the criteria 'Is Null'.
When I run the query, it merely lists all the members from Table 1.

I've built a form on my Access database that invites a user to enter a start date and an end date into two textboxes. When i press a command button, a parameter query runs which uses the two textboxes as the parameter's criteria. However, to ensure that both textboxes have a data entry, i have tried entering in some VBA that prompts the user to enter in a date if its left null...then set focus to that textbox: Here it is...
If IsNull(Me.txtWeight1) Then MsgBox "You must enter a minimum weight!"
Me.txtWeight1.SetFocus
Else
If IsNull(Me.txtWeight2) Then MsgBox "You must enter a maximum weight!"
Me.txtWeight2.SetFocus
Else
If IsNull(Me.txtWeight1) And IsNull(Me.txtWeight2) Then MsgBox "You must enter a min and max weight!"
End If
This will not compile for me! I've tried with and End If and without an End If and other stuff. Why won't it work?

hi guys.. i want to include a search form in my database.. here is my current SQL statement:
SELECT tblCompany.CompanyIDPK, tblCompany.CompanyName, tblCompany.CompanyAddress, tblCompany.ContactPerson, tblCompany.ContactPosition, tblCompany.OfficeNo, tblCompany.MobileNo, tblCompany.FaxNo, tblCompany.EmailAdd
FROM tblCompany
WHERE (((tblCompany.CompanyName)=[Forms]![frmSearchClient]![txtSearchFor]));
but this statement only returns the exact name of the company... if the name of the company in the database is ABC company and you searched for "ABC", it will return zero results... so how can i improve on this? that even if they enter only "ABC", it will return a result.
thanks a lot and good day...

Hi all
I'm making a student report card. Teachers enter student data via a bound form. I have a text field that teachers enter their class which brings up student names. They fill oput the form accordingly.
I have 6 classes of grade 7. 7A, 7B, 7C and so on.
If a teacher enters something weird like (7 (space) A) the query bound to the form will return nill results because it's looking for something that doesn't exist. I need an error message to appear which says no records will be returned because you haven't entered the correct parameter value. (Because they have entered 7spaceA rather than just 7A.
I could just use a combo and this would solve all my problems. But it's not always practical. I was thinking I could use a wild card where if the first character was a number then at least some values would be returned. There is method to my madness... I actually want to apply the same code elsewhere when running reports.
Is there a way I can enforce some kind of input mask in an event proceedure that can do this??
I appreciate any advice.

Hi,
I have data of type "number" shown in the drop-down combo-box in a form. It has some codes in the event of "After Update".
My problem is that i can't type in something like 13* in the combo-box in order to get anything starts from 13. It says "The value you entered isn't valid".
The reason is that i want user to be able to use the wildcard. I know that i can do this with text. I'm not allowed to change the structure of the table in the database.
This combo-box shows IDs from one of the exisiting tables. That IDs is of type "autonumber" in the table.
Is there a better way of doing this?
Thank you in advance

I've got a query that is defeating me, but that might be due to a week's worth of insomnia related sleep problems. My issue exists in the following query, of the four IIF statments in the HAVING portion of the query and the need to select all if the statement is false for each one of the four queries, the way it is now partly works by returning all results where none of the values are null, I need to get null results as well. I've tried not including the false action for them, a wildcard to select all and just can't get around this problem. Any help appreciated.

I am trying to get the OrderBy to recognize wildcards (or to that effect). A scenario would be I would have more than one name in a field, EX: Name2, 4, 6. How do I use wildcards in the OrderBy and they are recognized.
ORDER BY (Table.Field)="Name1", (Table.Field)="Name2", (Table.Field)="Name3", (Table.Field)="Name4", (Table.Field)="Name5", (Table.Field)="Name6", (Table.Field)="Name7", (Table.Field)="Name8";

I have a table called Coded_Data with one particular field called Codes. This field list a number and a respective code to identify what type of code it is. For instance 123456789-AD...123456789-ADS. I am wanting to create to two columns. One listing all work orders coded with AD and the other withADS. When I use the Like condition with % it returns both AD and ADS in same column. I understand why because the "%AD" returns anything that starts with AD so this is why I get both codes. I only want to get the the AD codes in one column and ADS in the other. I have duplicated the table twice since I am trying to retrieve data from the same field and table but display in 2 separate columns. The duplicated table has a different alias. The problem is in the where clause.
where (((coded_data.codes) LIKE "%AD")) or ((coded_data_1.codes) LIKE "%ADS");

I'd be grateful if someone could offer some help with this to a frustrated Access novice : )
I have a query that filters records according to the value of an unbound text box in my form (basically search on last name)
I want to introduce wildcards into the filtering process but cannot get it to work.
Here's what I've done:
In the criteria field I had
[Forms]![MAIN]![Text440]
refering to the unbound text box on the form already mentioned.
This worked fine, but the following:
Like "*[Forms]![MAIN]![Text440]*" does not.
Nor does various combinations of brackets such as:
Like "*([Forms]![MAIN]![Text440])*"
In fact it now doesn't return anything, even if given a positive match. I have trawled help and the forums but to no avail. I have also tried the % character instead of *
I am using Access2000...

I have created a simple Unbound search form based on a 'Bookings' table. There are 4 comboboxes that the user can choose to search on, 'Client_ID', 'BookingType', 'FundingArea' and 'ChargeTo'. I have created a query that uses the following criteria;
Like "*" & [Forms].[frmLBT_db_Tool].[cmbName] & "*"
Like "*" & [Forms].[frmLBT_db_Tool].[cmbBookingType] & "*"
Like "*" & [Forms].[frmLBT_db_Tool].[cmbFundingArea] & "*"
Like "*" & [Forms].[frmLBT_db_Tool].[cmbChargeTo] & "*"
Using this criteria any of the comboboxes can be left blank and the results will display the chosen combobox used, or if 2 comboboxes were used the results would be further filtered.
The problem I have is that if a name was chosen (cmbName - Client_ID) and the Client_ID was 2, then all Client_ID records which have a 2 in them are returned, 2, 12, 20-29,32,42,52 etc...
Is there a way to overcome this, or am I going about it all wrong?

I have a table in access which is updated weekly; I need to create two tables from this updated table.
1st table will consist of all the new entries for the current week
2nd table will consist of all the entries from the previous week - an amalgamation of all the entries which are not from the "current week" (table) For example; the table below shows the two entries from last week.
ID
Name
1
Adam
2
Ben
This week I have three new entries New entries
ID
Name
3
Charles
4
Richard
So when I run the same query next week I will get something like this.
Old Entries
ID
Name
1
Adam
2
Ben
3
Charles
4
Richard
[code]....
How do I get a query /queries which divides up the weeks new entries and also all the old entries.

I have a table with a string field for a street. It might have data such as:
Bleeker Street
or Bleeker St.
I want to create a query that will enable the user to search for a string by entering a parameter. Is there a way to construct a query using wildcards for a string so that if the user types in "Bleeker" both the above values will be returned?
Thanks.

Been trying to use wildcards in fields while Filter By Form instanced in Access 2007.
LIKE, BETWEEN, IN or */% not available?
The form is based on a query. I am guessing this is why the drop downs only show IS NULL or IS NOT NULL as choices instead of the entire unique list existing in the underlying table/query.

I have a Excel spreadsheet with an embedded query that pulls from an Access table. The users use a spreadsheet with an embedded query to search on a field called "Circuit ID", to bring up results showing the history of a given circuit id. Currently they have to enter an exact match, for example if the circuit id value is DHECHUIOY, they need to enter this exact value DHECHUIOY. They want instead to be able to enter DHEC and a wildcard character to bring back every value that begins with DHEC. There doesn't seem to be a way to do this in a spreadsheet with an embedded query.
I finally decided that it would be easier to create a form in Access
How I can create a form which allows users to search on a value using wildcard characters ? (the user enters the wildcard character).
I'm on Access 2012, Windows Vista

How do you search for any number of numeric characters using wildcards? The # symbol only searches for 1, and * obviously includes letters.
Example:
I have:
D1234
D3
D5336767
D123F
My search should only retrieve the first 3 values.
WHERE FieldName LIKE 'D[0-99999999]' does not seem to work.

I have a list of consumables;
Syringe 50ml
Syringe 20ml
Syringe 5ml
Syringe Cap
White Needle
I want to remove only the number and the ml part from the list, so I would end up with;
Syringe
Syringe
Syringe
Syringe Cap
White Needle
If I use
PHP Code:
Replace([DrugNameVial],"50ml","")
I get the desired result for the 50ml syringe size.
I have tried every possible combination of "**ml", "##ml", "Like [0-9]ml all with no success.
How this can be resolved without having to individual enter each syringe size "5ml", "20ml" etc
I can't even just take the text from the right till the first space as this would lead to problems with other consumables in the list.

I do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null
