How to write an expression/criteria in a query that will return only ID numbers with alpha numeric values. Example: My Id field contains both numeric 479621, 680530 and alpha numeric 132NAV100, 174NAV26a values. I want to run the query to return only the alpha numeric values.
I do not know SQL nor VBA.
I have two date fields in a table. I need to find the days between these dates and, if its greater than 7 days, I want to display the record in a report, so far, I have found a hand function that allows me to enter two dates and it returns a long data value representing the number of days in between the two dates. (google "I've developed the following code to count the business days between 2 dates." and its the second one that starts as SOLVED I made no mods to it as it does what i need it to do.
So, i added this to its own module within the data base for use within a query. My test query basically displays the unique ID, the start date and the end date and then displays the values returned from the function. here is the SQL:
SELECT [Main Table].[Unique ID], [Main Table].[Start date], [Main Table].[End Date], (Business_Days_Between([End Date],[Start date])) AS [Days between]
FROM [Main Table]
WHERE ((([Main Table].[Start date]) Is Not Null) AND (([Main Table].[End Date]) Is Not Null));
When ran, this Query works... However, when I enter a criteria like =2 or > 7, it says data type mismatch. I have even attempted the CInt() function to make sure its formated as int but i continue to get the same error.
I have an expression in my query and i'd like to return a value of 0 is the expression yields a null value. Here is the expression i have:
IsNull(Sum(([qryTime].[hours]*[Rate])+([qryTime].[minutes]*[Rate]/60)+([qryTime].[seconds]*[qryTime].[Rate]/3600),0)
I'm getting an error "the expression you entered has a function containing the wrong number of arguments". How can i resolve this?
I have a field created in a query expression
BirthMon: Format([DOB],"mmmm")
I would like to create another field in the query using DLookup to return the value of the BrithMon.
BrithMonthID=DLookUp("MonID","tblListMons","BirthM on = Mon")
This works good if used with an unbound text box on a form, but when entered into a query expressions, an error is returned: cannot find the name 'BirthMon'
Can I used DLookUp in a Query expression to refer to another Query created field?
I'm a little new to Access but I'm trying to create an IIf Expression:
iif ( condition, value_if_true, value_if_false )
Mine is: Au_ppb: IIf([Element]="Au" And [Units]="ppb",[Result],Null)
I need to have three criteria's (each looking into a different column). I can get two criterias but not three:
[Element]="Au" And [Units]="ppb"
When I add in the third (And [Priority]="12") it doesn't work .
Also, I need to have about 6 columns with similar IIF statements in the one query in my query and if a row has Null for all then I don't want it visible however if I make the Criteria "Is not Null" on one column or on all it comes up with no results.
I have two tables, TBL_Students and TBL_Email. Each of these tables have a field called Category, which allows multiple values from a list.
Is there a way to return records from TBL_Students where at least one value in TBL_Students!Category = at least one value in TBL_Email!Category.
E.g. If Student A has categories Maths, Physics and Computing;Student B has categories Maths, English and History;Student C has categories Physics and Geography
I would expect:
when TBL_Email!Category = Maths,Physics : Students A,B,C to be returned
when TBL_Email!Category = Maths : Students A,B to be returned
when TBL_Email!Category = Physics,Geography : Students A,C to be returned
I want to return the price from my transactions table for the value '1' in the ID field in this transactions table.
That would be my first field in the query. The next one would be to do a sum of the sellprice field in my 'inventory' table where the buyingID matches a value of '1'.
how to accomplish this? So far, I'm not getting the query to return anything on the relationship.
I have 3 main tables: tblEmployees, tblJobs, and tblProcedures. (See attachment for relationship diagram and additional supplemental tables).A job can have multiple procedures and an employee can have multiple procedures too.
I need to write a query such that when searching by a specific job I can see all of the employees who are qualified for that job. This is done by seeing which employees have the procedures that belong to a job. But here's the catch: since a job can have multiple procedures, if an employee only has some of the procedures I don't want that particular employee to return as a search result. The employee must have ALL the procedures that belong to the selected job.
So for instance if I have:
tblJobs
Job1
tblEmployees
Emloyee1
Employee2
[code]...
If I search by Job1, I want only Employee2 to return as a result, NOT Employee1.I am at a lost for how to construct the SQL for something like that.
I have a query I'm working with that finds data that changes, calculates the numbers, then prints a result in another column. The problem is that if I don't have any changes, then I have a blank result. Normally this wouldn't be a problem, but I'm making reports available to other users and would like this populated.
What seems simplest is to add an expression in the criteria field for the column that displays data after crunching numbers. Since this only has a display if something has changed, then I need an expression added if there is no data. Can I add something like an IsNull expression to display the results from another column in the same table? The data will end up being redundant, but I'm ok with that for now. the report should probably have the expression, but the column is already here in this table.
I have a table that has a list of tasks and checkboxes attached to them to be checked once the task is completed. I need to run a query on the table that will only bring me back the tasks with a completion that is false.
Everything that I read online indicates that this is a difficult task for access. Maybe I can accomplish this in SQL view instead of design? If I put false is all of the yes/no fields, the query brings back nothing.
I have a table that contains readings from several pieces of equipment as well as the status of each one. Each record has a timestamp, equipment number, status, etc. What I want is to create a query that will return the latest record for each equipment number. Simplified example table:
Timestamp EquipmentNumber Status
Today ------Machine1 ----------Running
Today ------Machine2 ----------Running
Yesterday -Machine1 ----------Down
Yesterday -Machine2 ----------Running
There are more than 20 different Equipment numbers and they are read several times per day and sometimes some of them get missed. What I'm looking for is a way to get a list of all the machines with their latest reading so they can tell which machines are running and which are down based on the last time they were read (instead of specifying a date). I can get this for one machine with no problem. I'm having trouble getting it for more than one machine. I tried a union query (with just 2 of the machines included for testing) but it only returns the results from one machine:
Code:
SELECT TOP 1 TestCompressorRoundQuery.LoggedAt, TestCompressorRoundQuery.AssetNumber,
TestCompressorRoundQuery.CompressorID, TestCompressorRoundQuery.Status, TestCompressorRoundQuery.CompressorIntegrity, TestCompressorRoundQuery.Notes
FROM TestCompressorRoundQuery
WHERE (((TestCompressorRoundQuery.AssetNumber)="104399"))
UNION ALL
[Code] ....
I'd rather not have to create a seperate query for each machine and then join all of those together! I think perhaps a Union query might not be the correct approach. All the data is coming from only one table.
I have two tables of data. One contains balances for a set of accounts (one unique balance per account, per date). The other contains transactions for a subset of the accounts (multiple records - or possibly none at all - per account, per date)
I'm trying to write a query to return the sum of the transactions from the Transaction table, for each unique account + date combination which is present in the Balance table.
Here is my SQL :
Quote:
SELECT tblBalances.BalDate, tblBalances.AccountID, Sum(tblTransactions.Amount) AS SumOfTransactions
FROM tblTransactions RIGHT JOIN tblBalances ON tblTransactions.AccountID = tblBalances.AccountID
WHERE (tblTransactions.TransDate=tblBalances.BalDate)
GROUP BY tblBalances.BalDate, tblBalances.AccountID;
This works fine with one major problem; if there are NO transactions for any given account + date in the Transaction table, I get no record for that combination in the dataset.
What I need is for the query to return a 0 in those situations (i.e. I should have as many records in my queried dataset as there are in my Balances table, but SumOfTransactions may be 0 for some of those balances)
I've tried the following but it has no effect on the outcome :
Quote:
SELECT tblBalances.BalDate, tblBalances.AccountID, Nz(Sum(tblTransactions.Amount),0) AS SumOfTransactions
FROM tblTransactions RIGHT JOIN tblBalances ON tblTransactions.AccountID = tblBalances.AccountID
WHERE (tblTransactions.TransDate=tblBalances.BalDate)
GROUP BY tblBalances.BalDate, tblBalances.AccountID;
Quote:
SELECT tblBalances.BalDate, tblBalances.AccountID, Sum(Nz(tblTransactions.Amount,0)) AS SumOfTransactions
FROM tblTransactions RIGHT JOIN tblBalances ON tblTransactions.AccountID = tblBalances.AccountID
WHERE (tblTransactions.TransDate=tblBalances.BalDate)
GROUP BY tblBalances.BalDate, tblBalances.AccountID;
I cannot get my query to return result when I enter the month of "June" as search criteria. June is listed in the table and query, every other month is returned except June.
I have attached two example for your reference.
I have a query that uses two criteria from a user input form. On the form, the user would input a customers last name and use a dropdown list (based on a table 30,60,90,120,365 days) to select how many days previous they want to search. Unfortunately there is something that I'm over looking and can't figure out.
Let's say I have multiple records that match the following criteria: Last name "James", days since contracted all less than 30 days. For some reason when I put in "James" as the last name in my form and select "30" from the droplist, it only lists the most current one which is zero days. Even if I select "60" from the droplist, it still only shows the zero day contract.
If I go back and select "90" from the droplist is brings up 3 - 3 day old contracts and my 1 zero day old contract. If I select 120, it picks up another contract that is 4 days old. If I select 365 it picks up a couple more, but still not everything. Here is my SQL code.
Code:
SELECT tblAllData.[F&I Manager], tblAllData.[Reviewing BOA], tblAllData.Date,
tblAllData.[Stock#], tblAllData.[Deal Date], tblAllData.[Cust First Name], tblAllData.[Cust Last Name],
Round(DateDiff("d",[deal date],Now()))/1 AS Days, tblAllData.[Bank Name],
[Code] ....
I am trying to count the amount of records that were created and closed for last month but I am having problems inserting the correct criteria along with the DCOUNT syntax. DCount("*","obsvnofilterqry","(Date_Closed)=MONTH( Date())").Works fine but figuring out how to get the amount of Date_Closed for last month is proving tricky.
View 11 Replies View RelatedI'm trying to create an query that has two separate expression in it and a date selection criteria. The first expression is,
Expr1: DateDiff("s", [Arrival Time 1],[Departure Time 1])/3600
and the second is,
Expr2: IIf([Expr1]>[Hours Per Day],[Expr1]-[Hours Per Day]
When I run this query it asks me for the date (which is fine) but then it also pops up a box asking for "Expr1". How can I get "Expr2" to use the value returned from "Expr1"?
I have a query which runs fine until I set a criteria (of True) in the field
Code:
chase_it: prevwd([practice_bacs_submission_date])<Date()
So without the criteria, I have
Code:
SELECT prevwd([practice_bacs_submission_date])<Date() AS chase_it, practice_bacs.practice_bacs_submission_date
FROM practice_bacs
WHERE (((practice_bacs.practice_bacs_submission_date)>#1/31/2013#));
and in the query results I see 0 and -1 as expected for the 'chase_it' expression BUT When I add True (or -1, or 0) as a criteria for 'chase_it', I get the "Data type mismatch in criteria expression" error.So the sql that fails is
Code:
SELECT prevwd([practice_bacs_submission_date])<Date() AS chase_it, practice_bacs.practice_bacs_submission_date
FROM practice_bacs
WHERE (((prevwd([practice_bacs_submission_date])<Date())=True) AND ((practice_bacs.practice_bacs_submission_date)>#1/31/2013#));
In case it's relevant, my function prevwd is:
Code:
Function prevwd(dt As Date) As Date
10 On Error GoTo prevwd_Error
20 dt = dt - 1
30 While Weekday([dt]) = 1 Or Weekday([dt]) = 7 Or IsBankHoliday(dt)
[code]...
and this function is used extensively and always works perfectly. I have tried using DateAdd instead of dt = dt - 1, but that made no difference.
I am trying to create a parameter query to return dates that have 2 years remaining.
For example I have dates for when mortgages expire, and I want to recognise the dates that have two years remaining using a parameter query but I can't figure out if I use DateAdd or DateDiff.
I am trying to use the expression below to transpose strings of 4-6 numbers (140504) to a string of 8 numbers with "20" in front (20140504). Some of the [Receive_Date] fields are empty or are 0, and in those cases, I need the expression to return a null value.
New_Receive_Date: IIf([Receive_Date]=0,"",IIf([Receive_Date]="","",Format([Receive_Date_YMD],"000000")+20000000))
The Format(...) part of the expression works fine on its own, but I am new to dealing with null values in my expressions, and when I add the rest of the expression, all '#Error' values are returned.
I'm trying to create an expression to calculate percentage.
The fields, Value A and Value B might both have null values, but I do not want Access to treat nulls as zero (as in the Nz() fn). How do I get the expression to exclude any nulls and not calculate for those rows, but set the calculated value for a row with null A or B to zero.
I want it to set no calculated value to zero so I don't get overflow errors and can therefore order the data by the calculated field.
I have this linked table query from a OBDC and I need to be able to filter out specific dates in that query. The dates in the table were in text format and I converted the dates using the CDate function. I wanted to filter the query to a single date and always I get the Datatype mismatch in criteria expression error.
However, filtering dates does work only when there are other specifications in the criteria fields (e.g. if I specify a date and and name). My SQL code in error looks like this:
SELECT
purch_hist.PUITM AS ITEM,
purch_hist.PUPO AS PO,
purch_hist.PUQTY AS QTY_RECEIVED,
CDate([purch_hist.PURDT]) AS RECEIPT_DATE,
itmcnt.ITBYR AS BUYER,
purch_hist.PUCST AS UNIT_COST,
vendor.NVNO AS VENDOR NO,
[code]...
This query works fine with a non converted date field, however the dates I need are in text format and need to be converted since I do not have permissions to edit the tables.
I am working on a fairly ancient manufacturing database that identifies items using a combination of letters and numbers. The usual format is to have a letter (which suggests something about the item type) followed by a sequence of numbers.
I am trying to write a query that looks up all the records beginning with a prefix or arbitrary length, strips away the text, and finds the highest number.
Code:
SELECT Right(LocalID,Len(LocalID) - 1) As IDSuffix
FROM tblItemIDCrossReference
WHERE Left(LocalID,1) = 'T' AND IsNumeric(Right(LocalID,Len(LocalID) - 1)=True)
This query produces the error given in the title of this thread, whilst the following works:
Code:
SELECT Right(LocalID,Len(LocalID) - 1) As IDSuffix
FROM tblItemIDCrossReference
WHERE Left(LocalID,1) = 'T' AND IsNumeric(Right(LocalID,5)=True)
This related query also works and shows a load of -1s and 0s correctly
Code:
SELECT Right(LocalID,Len(LocalID) - 1) As IDSuffix,
IsNumeric(Right(LocalID,Len(LocalID) - 1)=True) As Alias
FROM tblItemIDCrossReference
WHERE Left(LocalID,1) = 'T' AND
But once again shows the error message when I try to filter the field Alias to -1 or 0 only through the right-click menu.I have tried piping Len(LocalID)-1 through CLng, CInt, Int, CDbl and CSng; this changes the error to 'Invalid Use Of Null' I have also tried removing the '=True' from the IsNumeric() term.
I have an update query for tGLCashAccount where it adds a value from another table with the BeginningBalance to arrive at CurrentBalance.
Here's what it looks like in design view:
Field: CurrentBalance
Table: tGLCashAcct
Update to: [tMakeNewCashBal].[TotalPrice]+[tGLCashAcct].[BeginningBalance]
Here is SQL code:
UPDATE tGLCashAcct, tMakeNewCashBal SET tGLCashAcct.CurrentBalance = [tMakeNewCashBal].[TotalPrice]+[tGLCashAcct].[BeginningBalance]
WHERE (((tGLCashAcct.GLCashAcctID)="102"));
I get the error: data type mismatch in criteria expression when I run it.
When running a query, I want to hide duplicates records for a given field. PO# will have many duplicates, depending on how many part numbers were order on the same PO#. Other unique fields are not displayed. Can an expression help with this? If not, how do I go about hiding them in a query?
Current Query results:
DATE PO#
08/18/2005 ABCD
08/18/2005 ABCD
08/18/2005 ABCD
08/18/2005 ABCD
Desired Query results:
08/18/2005 ABCD
Thanks in advance with any help!
If I want to sum the percentages from April, May and June only if a column is Not Null, how would I do that?
example
Tbl 1
PK, Month
Percent
Tbl 2
FK, Month Enrolled
Qty of Rx in the 1st month enrolled
Qty of Rx in 2nd qtr
Base (if Qty of Rx in 2nd Qtr is null then Qty of Rx in 1st month enrolled)
If Qty of Rx in 2nd QTR is NOT NULL then QTY of Rx in 2nd Qtr * Sum of April Percent+May Percent+June Percent, otherwise Qty of Rx in 1st month enrolled * Month Percent
Im getting stuck on how to sum the percents of April, May and June and then multiplying the result times the Qty ONLY IF the field is not null.
I only know how to create Query's using the design mode. I dont know how to write SQL statements.
i made a query to display students results after an exam. there are 12 subjects but a student chooses 8 from that. After an exam, the results are keyed in and a result slip is printed later. The problem is that the result slip displays all subjects including those not done by the student. I typed a criteria >0 in one of the fields and no records appeared. Is there a way that i can use to display only the subjects chosen and marks attained by a student and leave out the rest?
