I am comparing the columns in two tables in a JOIN to see if there are differences. The columns, COL3 and COL4, are "Text" fields. They are declared as:
Field Size = 255
Default Value = "" (an empty string)
Required = No
Allow Zero Length = Yes
Indexed = No
I use the SQL comparator <> in my test... so ...
Code:
SELECT * FROM
Table_A AS Tgt
LEFT JOIN Table_B AS Src
ON (Src.Col1 = Tgt.Col1 AND Src.Col2 = Tgt.Col2)
WHERE Src.Col3 <> Tgt.Col3 OR Src.Col4 <> Tgt.Col4
I expected that where Src.Col3 was set to 0 (the string character zero) and Tgt.Col3 was set to the default of "" (a zero length string) that the query would return that row? It does not however? No doubt this is tied in with the old NULL string and Empty string chestnut?What is the best way to compare "text" fields in Access.
I'm using Access and VB for the first time, trying to develop an application for hobby use. I built and populated my database, and I'm building my first module. Unfortunately, one of the most simple actions is tripping me up. I'm attempting to perform an action only if a 255-character text field in a file doesn't contain data, but comparing it to " " or "Space$(n)" doesn't yield the actions I'm expecting.
Hi all- I'm creating an update query.I have a field [dateLastEdit] that is stored as text, I have to compare it to a date entered on a form by user [date_from] (I need to select all dates greater than this) but I'm running into problems:when I use date_from in text or date format and compare it to dateLastEdit in text format the comparison is made in numeric order(so 12/02/2006 is selected as well as 12/02/2005 when date_from is 12/01/2006)SELECT PTSData.LastEditDateFROM PTSDataWHERE (((PTSData.LastEditDate)>=[Forms]![chMgmt_frm]![date_from]));when I use date_from in date format and compare it to dateLastEdit converted to date format I get "expression typed incorrectly or it is too complex to be evaluated" msg.SELECT DateValue([LastEditDate]) AS Expr1FROM PTSDataWHERE (((DateValue([LastEditDate]))>=[Forms]![chMgmt_frm]![date_from]));[LastEditDate]'s format is always mm/dd/yyyy hh:mm:ss, but as text, not date data type.I've tried CDate with same results, isolating it in its own query to test it, using hardwired dates as criteria, but no joy, am I missing something obvious?forgot to add- I've used all the above with left also to select only date portion with same results
I have found a SQL Query I have tried to use, however I am having no joy. The query is such:
WITH rows AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY VisitID) AS rn FROM Data ) SELECT DATEDIFF("n", mc.EndDTM, mp.StartDTM) FROM rows mc JOIN rows mp ON mc.rn = mp.rn - 1
I've put in -100 as an arbitrary never possible number. Obviously, this does not return Null values.
Question: How can I return both Null & Numbers when the Textbox in the form is left blank? in all the columns. Currently, I am not getting Null values
Code: >IIf(IsNull([Forms]![MainForm]![Criteria]),SHOW ME EVERYTHING INCLUDING NULL VALUES & NON-NULL NUMBERS,[Forms]![Material Finder]![txtPS])
or in other words
If the textbox is blank, show me all the data available, else if it is not blank then show me only the values that are greater than the number entered in the textbox from within column A, B, C, D ....
I recently (temporarily)took over a position that uses an Access database that does not work properly, and I'm stumpped on how to fix it.
The query is supposed to pull all data where the "Date Overdue" field is less than today.
"Date Overdue" is a calculated value that pulls from the field "Date Input", which is in a text format (DDMMMYY) Such as 03NOV13. It is 8 days after the date input.
It prints out like this: "Monday, November 11, 2013" which is 8 days after the 3rd.
"Date Overdue" is set to this value:
Code:
DATE OVERDUE: DateValue(Left([DATEINPUT],2) & "/" & Mid([DATEINPUT],3,3) & "/" & Right([DATEINPUT],2))+8 "Date Overdue" has the criteria "<DateValue(CDate(Now()))"
I'm not going to go into all the different steps I've taken to try and get this to work because I've toyed with it a lot..
The output that I always seem to get is a mixture of all records that are available, before and after today's date, I just wanted those that are less than today.
I suspect that the date values that are shown in the query aren't true dates because when I click on the filter button it gives me this error:
"Syntax error (missing operator) in query expression 'DATE OVERDUE' "
NOTE: I'd like to add that this is just a regular Select query.
Code: SELECT DateValue(Left([DATEINPUT],2) & "/" & Mid([DATEINPUT],3,3) & "/" & Right([DATEINPUT],2)) AS [PRODUCT END PERIOD], DateValue(Left([DATEINPUT],2) & "/" & Mid([DATEINPUT],3,3) & "/" & Right([DATEINPUT],2))+8 AS [DATE OVERDUE], [QBR ON EQUIP].DATEINPUT, [ALL ERRORS].[ERROR STATUS],
I have a report where my customer wants to be able to input a value and then be able to select whether the report shows values above or below that value. I have a combo box that has 2 values (1=Less than or equal to, 2=greater than or equal to). There is a text box where he inputs the rate to compare against (e.g. $75). When he hits submit, the application stores the values of the combo box and text box into global variable and then I have a public function that can be used to retrieve the values. GetHRate() gets the value to compare against and GetHRateCompare() gets the value to indicate <=(1) or >=(2).
In my query for criteria for rate I have this expression: IIf(GetHRateCompare()=1,"'<=",">=") & GetHrate()
I've tried every combination of double quotes, single quotes, no quotes moving the GetHRate inside the IIf statement and nothing seems to work.
If I just hardcode <=GetHrate() into the criteria it works perfect but that does not achieve my goal of letting him select over/under at run time. Here's the full query:
SELECT qryCustomers_AverageTimeByScheduleID.ServiceName, qryCustomers_AverageTimeByScheduleID.ScheduleID, qryCustomers_AverageTimeByScheduleID.SumOfTotalTim e, qryCustomers_AverageTimeByScheduleID.PropertyID, qryCustomers_AverageTimeByScheduleID.PropertyName, qryCustomers_AverageTimeByScheduleID.MonthCount, qryCustomers_AverageTimeByScheduleID.AverageTime,
I have a query based form i use to gather data to generate a report. I have 2 forms Form A is where users open all reports from. On form A i have 2 unbound fields "Report Start Date" and "Report End Date" my queries us these from Form A as the criteria for the queries. I have like 30 reports using this method and it works great. I am now building 2 new reports, a monthly and a weekly report. These reports required and data entry point so i built "Form B"
I created my tables for these reports and went through and created the records. So when a manager needs to enter data for any given report they would us "Report Start Date" to identify what record they want to work with, so if they want to enter data for the December report the would select 12/01/2014 and then open "Form B". This works great and the report looks as good as any Access report can.
Now they are asking to add to "Form B" a comparison to the previous month or week depending on the report. for example:
This month we did 250 units Last month we did 300 units so we did 15% less "Yes my math is not exact"
They don't need to see last months data but i need a way to query the previous record to compare the data
This is the criteria code i use in the query that "Form B" is based on.
Code: [Forms]![Form A]![Report_Start_Date]
I am pulling up the 12/01/2014 in "Form B" but need the 11/01/2014 record floating behind to compare data.
How can i use the same setup but pull a 2nd record? I am thinking i can use a 2nd query but with different criteria.
I currently import data into a table and it it has a text field which looks like this: 12,345.67 GBP...I need to use a query to make this a number field so that I can sum it's contents. I've managed to remove the 'GBP' part but can't seem to get rid of the comma?
I'm building a query from tables and there is a field i called it: Weight, that should contain the value from the Description field. The Description field is a text field and it always end with the format as --T, with -- as number, and it can be either 1 or 2 digits, no more.
For example: 2T, 48T, 2T, 36T
So, the whole Description field value is always like this: Bla bla bla 2T, OR: heheheheh 24T
The thing is before the --T, sometime people put in 1 space, 2 spaces or multiple spaces, for example:
This is a test [space]6T This is a difficult test [space][space] [space] [space] 52T This is an easy test [space] [space] [space] [space] [space] 40T I hate taking test [space] [space] 1T
So the field Weight should contain the value 6T, 52T, 40T, 1T only
I have 4 fields that are unbound on a form. img1 img2 img3 img4..When these are entered they are all combined and autofill another unbound textbox = imagename.. what i would like to do is from this unbound textbox 'imagename' ..i would like to populate a textbox that IS bound called FileName
[Event Procedure] Private Sub imagename_Click() Me.imagename = Me.FileName End Sub
I am trying to search for specific text in a field and returns its value. For instance some of string includes Sub, L2L, Temp, Model, or MTM and I would like a query to return these values if found.
Is there a function or query that I can split a field into different columns?
For example, I have First Name, Last Name, Address.
But I want to split the address field into Address1, Address2, Address3, Address4 as the initial Address field has a lot of characters with commas e.g. 11 London Road, Liketown, Likeshire, London.
So, I want to be Address1: 11 London Road, Address2: Liketown, Address3: Likeshire, Address4: London.
I thought that I can export the field using a simple query and then re-import it with using the text field into columns option, but it is time consuming.
I am trying to perform some keyword searches of a text field. My preferred option would be to hold all the keywords in a separate table and then use something like
SELECT * FROM Text Table, Keywords Table WHERE (((InStr[Text Table].[Text],[Keywords Table].[keywords])) > 0 ));
This works and returns anything which has the string from the keyword table, however I wanted to look for whole words only. I can do this in SQL using a regular expression along the lines of [!a-z] keyword [!a-z] which only finds the string where it has no letters directly either side of it.
What I would like to do is combine the two methods so I hold my keywords in a table and then use them with the reg ex to find whole words only.
I created an update query to a text field in a table. However, it inserts the data at the end of the string and I need to insert it at the beginning of the string that already exists. How do I move it to the front instead of the end?
I have a field that is text format. However many of the records in that field contain numbers.I want to delete all the records that are numbers in this text field, leaving only records with textual data.
I have a table ("tbl_idq_all") with a text field for product codes ("scode"), a date field (dd/mm/yyyy) and a quantity field ("po_qty"). This table therefore holds future receipts of stock for products.
What I am having trouble doing is create a running total of [po_qty] based on [scode] and [Date].
A good example is stock code 10254. This has a quantity of 40,032 arriving 01/06/2013 and a quantity of 30,096 arriving 01/09/2013.
I have a query that I am sending as a spreadsheet to various service technicians listing parts that they need to take inventory of. Then, after they take the inventory, they send the spreadsheet back to me and I upload their counts back into my database. Right now, my query contains the Bin number, part number, part description, and a blank column for the technician's count. I have just learned, that the company does not want the Bin number to be visible in the report. In order to upload the technician counts into the database when they return the spreadsheet, I need to be able to reference the Bin number to get the count on the right line.
Is there something that I can do so that the Bin number will be visible in the report when the database reads it, but not to the technician?
The only solution I could think of was to format the Bin Number as a password. Unfortunately, I can't get that to work in the query results. If I save the bin number as a password in the table, is there a way to make it visible on reports for internal use (so the people in headquarters who are responsible for over all inventory can still see each bin number)? I found how to hide the field in the query results. However, when I send the results to the technician, the field is not there at all.
I am working with 4 tables and I am trying to get a count of the email address field in each table grouped by Email Group Name. I tried the dcount function but returned an error because some of the email addresses have an apostrophe in the field. Is there a way to do this in 1 query? This is an example of the result I would like:
I can add to my make table query UDate: Date() that will add a populated field to the output table that has today's date in it.
I can also add something similar like this for example V_Num: [V_Number] and when ran, will prompt with a dialogue box to add some data, it will then create the table with that new field name and populated with the text from the dialogue box.
But how can I automate this to skip the dialogue box and just add it to the expression?
I got a table salaries master I want to extract some info out of and calculate some values. The formula below doesn't work, I'm pretty sure it has to do with [pay period] being a text field. Is there no way to make it work?
