Microsoft Access is a database creation program that allows for anyone to easily maintain and edit a database. It is suitable. Microsoft Access tips Crosstab query tips. Provided by Allen Browne Created August 2. Last updated April 2. This article explains a series of tips for crosstab queries. An example. A crosstab query is a matrix, where the column headings come from the values in a field. In the example below, the product names appear down the left, the employee names become fields, and the intersection shows how many of this product has been sold by this employee To create this query, open the Northwind sample database, create a new query, switch to SQL View View menu, and paste TRANSFORM SumOrder Details. Quantity AS Sum. Of. Quantity. SELECT Products. Product. ID, Products. Product. Name, SumOrder Details. Quantity AS Total. FROM Employees INNER JOIN Products INNER JOIN Orders INNER JOIN Order Details. ON Orders. Order. ID Order Details. Order. ID. ON Products. Product. ID Order Details. Product. ID. ON Employees. Employee. ID Orders. Employee. ID. GROUP BY Products. Product. ID, Products. Product. Name. PIVOT Employees. Last. Name, Employees. First. Name Display row totals. To show the total of all the columns in the row, just add the value field again as a Row Heading. In the example above, we used the Sum of the Quantity as the value. So, we added the Sum of Quantity again as a Row Heading the right most column in the screenshot. The total displays to the left of the employee names. In Access 2. Totals button on the ribbon. The button is on the Records group of the Home tab, and the icon is an upper case sigma. Display zeros not blanksWhere there are no values, the column is blank. Use Nz if you want to show zeros instead. Since Access frequently misunderstands expressions, you should also typecast the result. Use CCur for Currency, CLng for a Long whole number, or CDbl for a Double fractional number. Type the Nz directly into the TRANSFORM clause. Edelbrock Pro Flo Tuning Software. For the example above, use TRANSFORM CLngNzSumOrder Details. Quantity,0 AS Sum. Of. Quantity. Handle parameters. A query can ask you to supply a value at runtime. It pops up a parameter dialog if you enter something like this What order dateOr, it can read a value from a control on a form Forms. Form. Start. DateBut, parameters do not work with crosstab queries, unless you a Declare the parameter, orb Specify the column headings. To declare the parameter, choose Parameters on the Query menu. Access opens a dialog. Enter the name and specify the data type. For the examples above, use the Query Parameters dialog like this Parameter. Data TypeWhat order dateDateTimeForms. Form. Start. DateDateTime OK Cancel Declaring your parameters is always a good idea except for an Access bug in handling parameters of type Text, but it is not essential if you specify your column headings. Specify column headings. Since the column headings are derived from a field, you only get fields relevant to the data. So, if your criteria limits the query to a period when Nancy Davolio made no sales, her field will not be displayed. If your goal is to make a report from the crosstab, the report will give errors if the field named Davolio, Nancy just disappears. To solve this, enter all the valid column headings into the Column Headings property of the crosstab query. Steps In query design view, show the Properties box View menu. Locate the Column Headings property. If you dont see it, you are looking at the properties of a field instead of the properties of the query. Type in all the possible values, separated by commas. Delimit text values with quotes, or date values with. For the query above, set the Column Headings property like this on one line Buchanan, Steven, Callahan, Laura, Davolio, Nancy, Dodsworth, Anne, Fuller, Andrew, King, Robert, Leverling, Janet, Peacock, Margaret, Suyama, MichaelSide effects of using column headings Any values you do not list are excluded from the query. The fields will appear in the order you specify, e. Jan, Feb, Mar,. Where a report has a complex crosstab query as its Record Source, specifying the column headings can speed up the design of the report enormously. If you do not specify the column headings, Access is unable to determine the fields that will be available to the report without running the entire query. But if you specify the Column Headings, it can read the field names without running the query. An alternative approach is to alias the fields so the names dont change. Cara Buka Wifi Orang. Duane Hookom has an example of dynamic monthly crosstab reports. Multiple sets of values. What if you want to show multiple sets of values at each matrix point Say the crosstab shows products at the left, and months across the top, and you want to show both the dollar value and number of products sold at each intersection One solution is to add another unjoined table to get the additional set of columns in your crosstab a Cartesian product. Try this example with the old Northwind sample database Create a table with one Text field called Field. Name. Mark the field as primary key. Save the table with the name tbl. Xtab. Columns. Enter two records the values Amt and Qty without the quotes. Create a new query, and paste in the SQL statement below. TRANSFORM SumIIfField. NameQty,Quantity,QuantityOrder DetailsUnit. Price AS The. Value. SELECT Products. Product. Name. FROM tbl. Xtab. Columns, Products INNER JOIN Orders INNER JOIN Order Details ON Orders. Order. ID Order Details. Order. ID ON Products. Product. ID Order Details. Product. IDWHERE Orders. Order. Date Between 111. And 33. 11. 99. GROUP BY Products. Product. Name. PIVOT Field. Name MonthOrder. Date The query will look like this It generates fields named Amt and the month number, and Qty and the month number You can then lay them out as you wish on a report.
