Queries :: Minimum Of Multiple Fields In Expression
Aug 26, 2013
I am trying to set up a calculated field in one of my form querries, using expression builder.
In one of my source tables I have 4 date fields called Inspection date 1 to 4
I need the lowest date among those inspectinos which are in the future (next inspection) If all 4 dates are in the past or Nulls, the function should return the current date. The logic of the expression could be:
The built-in functions DMin and Dmax work with single field arrays, witch would be perfect if the database were properly designed, but now I dont have the power to change this.
I am trying to create an expression in a query to sum only the # of hours a student attended between two date fields. I do not want to use a parameter because each student has different start and midpoint dates and I need to see all of them in one list.These are the fields I'm using in the query:
Student Name Start Date Midpoint Date Hours
It keeps giving me "0" or if I move the () around it says the correct syntax is [NOT]
Expr1: Sum([Hours]) between [Start Date] & [Midpoint]))
I have a query that is working, but I am looking to make it faster. We import 13 csv files daily into 13 Access tables. The files have an ItemID and price. We need to get the minimum of the raw data across the 13 tables & then manipulate the prices some (in the query) and get the lowest of the manipulated prices again for the 13 tables for each ItemID - some might be blank. We are using a MinOfList function in the query to get the minimum of the 13 numbers. But this is very time consuming since we have to run the Min function twice (with 13 input parameters) for each ItemID - about 15,000 records. It takes about 1 minute to run the query.
I am involved in centrally managing a project , a part of which involves employees of certain companies being given a weekly subsidy for study on academic courses. I have successfully set up a table for all the learners and a related table for companies.
Each learner will receive a fixed weekly rate subsidy in the first year, and a lower fixed weekly rate subsidy in the second year. Somebody (not me) will need to check their paychecks to ensure that employees have been paid and all is above board. The learners/employees can start on the programme at any time. I need a way to track this (total claimed amounts, where they're up to etc).
My theoretical solution, is to have a field for each week a learner is on the programme (52 first year, 52 second), and instead of entering a currency amount in the field, the check-person can enter the date they saw the evidence and are happy with it. I thought then if I create a query that searches any dates that fall within the current claim period (eg >01/01/2015, <=Date()), and multiplies field count that fall within those parameters by first/second year subsidy rate if they're in that table. I think my logic is sound, I am just not sure how to write the query/expression, or if it's possible, or if there is a much simpler way to do it.
I need to figure out the amount of days between two dates that do not exist in my database...I use this calculation to do waivers...I was able to build a table and put in the two dates and then build a query which calculates the days between the two but I wanted to know if I could build a query that prompts on a [start date] which I would enter and then prompts on an end date [end date] which I would enter to get the number of days between...is that possible?
I had...
WaiverDays: [Enter start date]-[Enter end date] but it did not let me run...I added () and it still did not run...
I tend to work with large amounts of data (extracts from company systems) and I create a lot of Access/VBA based tools to automate processes.
I have an annoying error which has always appeared but I don't understand the root cause of it.
When viewing a query, if I filter, I get an error message pop up (though after clicking through the error I can still use the filter function):
"syntax error missing operator in expression 'name of field'".
This seems to happen when I add several calculated fields. Here are some examples of the conditions and calculated field formulas I'm using in this current one:
Conditions: <>"CINEMATIC" And <>"SFX" Not Like "*_ZZ*" And Not Like "*test*" And Not Like "EP_*" [Forms]![FRMscriptPrintReview]![selectLangCombo]
I get the impression that its more of a bug with Access as the formulas aren't complicated really but need confirmation on this and if there is a way I can avoid it.
I have a normalised table containing the following fields:
<Unique ID> <Fund Name> <Date> <Return>
The data are time series denoting the monthly performance of investment funds. Funds can have any number of observations (e.g. March 1997 to June 2005). In addition, some funds can have performance gaps.
I would like to extract those funds that have a continuous performance history of 120 consecutive months between a specific start and end date. As an exmaple, the start date is July 1990 and end date June 2010:
- Fund A: performance history July 1995 to June 2005 (= 120 consecutive observations) INCLUDE - Fund B: performance history July 1995 to June 2007 (> 120 consecutive observations) INCLUDE - Fund C: performance history July 1995 to June 2000 (< 120 consecutive observations) EXCLUDE - Fund D: performance history July 1995 to and June 2000 August 2000 to June 2007 (> 120 observations but gaps) EXCLUDE - Fund E: performance history July 1985 to June 1995 (= 120 consecutive observations but only 60 after start date) EXCLUDE
how to build a query around this? Perhaps this needs implementation in VBA. Ideally, I would like to be able to select the start and end date dynamically and then run the query accordingly.
How to find the Minimum value of a column. This is my SQL:
SELECT * FROM tblFinalMaster WHERE (((tblFinalMaster.OperatingDay)=[forms]![frmEnterParameters]![Combo13]) AND ((tblFinalMaster.[Checkout Order])=([Forms]![frm01ATFTieLineCheckout]![Checkout Order])+2) AND ((tblFinalMaster.[From BA_REPORT])=[forms]![frmEnterParameters]![Combo5]) AND ((tblFinalMaster.[TO BA_REPORT])=[Forms]![frmEnterParameters]![Combo3]));
The part in blue, instead of pulling a +2, I want the Minimum value. Seems simple enough.
Expressions in Access have given me some trouble before. Mainly due to inexperience. I hardly ever work with them. What I am trying to do is make the default value of a form textbox control the minimum value of a field A in a table A. The datatype of Field A is Date.
So far I've got:
=Min([table A].[field A])
In the Default Value of the form's property sheet, but this just returns a blank value. I've had a look in the table and there is no value that is blank in field A.
I have 3 cross tab queries that are completely identical with the exception of the field that they pivot. Each field is searching for the same values just in different columns, with the end goal being to get the sum of the values for each pivoted column. I'm wondering rather than having 3 almost identical queries is there a way to use a crosstab to sum the values from each of the three fields rather that having 3 queries which then have to be aggregated in a fourth?

I have created a table with multiple Yes/No fields. I wish to create a query where the user can select from a form that displays all the Yes/No fields Is it possible for this to be done
Thanks for your help
REFINEMENT OF PROBLEM I have created a table for a small library at work. The items in the table are item_number, author, title etc. Also I wanted to classify each item into various categories. In the Table I have set the categories as Yes/No fields. An item can belong to a number of categories eg admin, finance,resources etc. What I would like to do is for a user to be able to interegrate the table via a query to find the articles that meet the criteria they want to search on. Ideally this would be done via a form that the user can tick the applicable categories (Yes/No fields). I tried setting up as parameter queries however this is very messy. Is there a way it can be done. Sorry for confusion in first posting.
I have a DB that consists of Movie titles and the multiple dates ( as many as 10) on which they will be used in the coming year.I built a flat table with 10 date fields.Then tried to build a relational table with just movie title and dates linked to ID.I cannot work out an ability to SEARCH the Database for a SPECIFIC DATE and get returned a listing of ALL Movie titles that will air on that date,
Is there a way to have one parameter in a query effect multiple fields?I have a table that details service calls on our equipment. There are columns in that table for each part of the equipment that get marked, depending on what needed serviced (i.e. software, printer, keypad, monitor, etc). I would like to be able to run a query that will show all the service calls where one part of the equipment was serviced multiple times without have to enter multiple parameters or write a union query (there would need to be 11 unions or 11 parameters for each part to be captured). For example, I would want to know how many pieces of equipment had 3 or more service calls on their software. I want to run the query without having to say that I don't care how many service calls were performed on the printer, monitor, or keypad. I would like to be able to say "Software >3" and have the query run on that information.
I'm trying to build a query that uses the information pulled from controls on a form called "CharacterCreation" - 2 of the controls are "Race" and "Class", and the form stores this data in a "Characters" table.The query needs to refer to the Characters table, and another table called "Modifiers".In this second table I have several numerical fields such as hp, str, etc, and I have two other fields called "Type_Modifier" and "Type" Among the Type_Modifiers are Race and Class, where their corresponding "Type" could be for instance Demon and Magician..
So the idea is that when I mark on the form (and thus creating the record in the first table) a Race of "Demon", and a class of "Magician" I want the query to refer to both of these fields, and sum the values in the second table where the "Type" is either "Demon" or "Magician" or whatever I decided to choose. I feel like I should be able to figure this out but I'm having a hard time..Here's an example of the SQL I've tried that shows nothing.
Code: SELECT Characters.Char_Name, Sum(Modifiers.hp) AS SumOfhp FROM Modifiers INNER JOIN Characters ON (Modifiers.Type = Characters.Class) AND (Modifiers.Type = Characters.Color2) AND (Modifiers.Type = Characters.Color1) AND (Modifiers.Type = Characters.Species) AND (Modifiers.Type = Characters.Race) GROUP BY Characters.Char_Name, Modifiers.Type HAVING (((Modifiers.Type)=[Characters].[Race]));
I also tried this, which I thought would work but it displays nothing as well.
Code: SELECT Characters.Char_Name, Sum(Modifiers.hp) AS SumOfhp FROM Modifiers INNER JOIN Characters ON (Modifiers.Type = Characters.Class) AND (Modifiers.Type = Characters.Color2) AND (Modifiers.Type = Characters.Color1) AND (Modifiers.Type = Characters.Species) AND (Modifiers.Type = Characters.Race) GROUP BY Characters.Char_Name, [Type]=[Characters].[Race];
I have a query that based on certain codes in a record does multiple joins to pull in other codes... I want the query (based on these pulled in codes) to do a lookup in another table to extract 1 field that has a description...
Can I do this in one query??? Do I need to do a Make Table to first pull in the codes and then do a second query with a DLookup based on those fields???
I have a table, which is being populated by a number of users. The table has 211 rows (customer field - this is a fixed amount) and there are 5 other columns (information which might or might not be available for that customer) which are all yes/no fields. Each row may could have any combination of ticks in those 5 columns.
I have a form to fill out this information, but now I need to use the data.
I'm trying to create one query which counts how many of each field are populated. I need it to give me the total of each of the "information" columns, and another to give me a list of all of the customers which have at least one of the information columns ticked.
I will also need to be able to see how many customers have all of the information columns ticked, and how many have none.
I have a table which has each claim as a single record. A client wishes us to provide the data in a format that lists the each procedure on its own line. I have attached a highlevel example of what the data currently looks like and what the query results should look like.So I need to create a query that would repeat the Claim Number and place all the Procedure fields into one field.
I have a series of numbers in 30 columns. I want to identify where either of two numbers appear in the same record regardless of which of the 30 columns they are in.
Code: Item Revision Start End 332 B 9/2/11 9/15/11 332 C 9/21/11 9/22/11 332 E 11/2/12 11/29/12 2A9 A 1/13/13 1/14/13 2A9 C 1/16/13 1/18/13
I'm trying to make a select query to provide the following output (RevisionStart-PreviousRevisionEnd):
Code: Item Revision Span 332 C 6 332 E 407 2A9 C 2
I've struck out with union queries and aggregating/sorting letters and don't know where else to look. Is there a specific name for this type of operation anyway?
I have a problem that I can't seem to solve in SQL for my access 2010 query.
Let's say I have a the price of and for every year.
In the tables I have A building number, a building type, and electricity and water predictions for this year and many upcoming years (up to 40 years)
I need to apply a change to any building with the building type BRT to show only 10 percent of the electricity and water for ALL years (up to year 2052). So building 5 would show 8.5, 5.4, 9.5, 7.4, and so on.
I have a database with two tables, one for the amount that was estimated in each cost section, and one for the actual amount billed for each cost section. The tables have the same number of fields, all with the same names. They can be linked together with event ID. Each table has over 100 fields and I would like to find the difference between what was estimated and what the actual was for each event. I would also like to see which cost section has the most and least variance. I am trying to do this without going through each cost and putting [tEst].[CostName]-[tActual].[CostName].
I have never created a single query that is this complicated.
I have a time card database that I created back in 2003 and over the years more and more new task have been added to track volunteer hours has been incorporated into it.
The current task at hand is to determine if each member has achieved or meet certain requirements each year. They are attend 8 or more meeting and check into 5 or more nets and be Net Control Operator for at least 1 radio net and be involved with 1 or more Public Service events. Sounds simple right?
I have a table that contains all the information that is need to get the result I want but am having a problem getting that result with a single SQL query. Everyone you talk to says use SQL query to obtain calculated vales and never store/save them.
So from the work table below meetings consist of 4,5,6,8,9 and nets consist of 10,11,14,15 and events consist of 2, 13 and the NCOflag is T/F.
So those are all the parts, count the number of meetings, nets, events and NCO and set the meets requirement flag T/F I keep getting "You tried to execute a query that does not include the in specified expression <name> as part of an aggregate function. (Error 3122)"
In this case it keeps complaining Callsign.
You did not enter an aggregate function in the TRANSFORM statement.
