Ms access switch statement
Switch function in microsoft access 2019 ( its is supported by
The argument list for the Switch function is made up of expressions and values in pairs. From left to right, the expressions are evaluated, and the value associated with the first expression that evaluates to True is returned. A run-time error occurs if the parts are not correctly paired. Switch, for example, returns value-1 if expr-1 is True. Switch returns value-2 if expr-1 is False but expr-2 is True, and so on.
Even if it only returns one of the terms, Switch tests them all. As a consequence, you should be on the lookout for negative side effects. An error occurs, for example, if the evaluation of any expression results in a division by zero error.
Returns the “ProductID,” evaluates the expressions in the “Switch” formula, and replaces all “True” expressions’ existing values with specified values. For instance, “PRO XYZ1” becomes “First,” “PRO XYZ2” becomes “Two,” and so on.
Note: The following examples show how to use this feature in a Visual Basic for Applications (VBA) module. Select Developer Reference from the drop-down list next to Search and type one or more words in the search box to learn more about working with VBA.
Using the switch function to simplify complicated nested iif
Here’s how it goes: We have a three-level tutor training program. The teacher can advance one level if they attend 10 training sessions and meet with students for 25 hours per level. So 10 Level 1 sessions plus 25 or more hours equals Level 1, 10 Level 2 sessions plus 50 or more hours equals Level 2, and 10 Level 3 sessions plus 75 or more hours equals Level 3.
I believe a SWITCH statement in either a question or report control will accomplish my goal, but I’m stumped on the syntax. (I was originally thinking nested IIF statements, but some research here suggested it could be easier to use a SWITCH – but see below for the truth of that!)
My ultimate aim is to build a report that shows how many face-to-face hours a tutor has received, how many training sessions have been completed in each level, and then present a measured indicator showing the tutor’s level.
I currently have a study that illustrates the first two facets of this by integrating a base report of tutors by name with two sub-reports (generated by query). I’m trying to figure out how to use the level indicator in the report… I’m always open to suggestions if anyone can think of a better way to complete the job!
Select case access
Microsoft Access queries are extremely simple to use thanks to the visual representation of tables and graphical connections between them, which hides the difficulty of writing raw Microsoft Access SQL. Fortunately, the user interface also allows for advanced and efficient research. The entire database engine is built on SQL systems, and it can move between graphical and SQL query architecture. This feature taught SQL to many Microsoft Access users and developers.
Knowing how to use the different features of Microsoft Access queries helps you to conduct advanced analysis without having to program. This presentation covers the fundamentals of queries while also disclosing a host of nuanced aspects. It soon progresses to more advanced stages.
Select queries return all records that match your search criteria. There are times when you only need a subset of the results, such as the top or bottom number of records. Similarly, you may only be interested in the top or bottom ten percent of records.
This is a simple method. You may determine the number of records to view by changing the query’s Top Values property (right mouse click on the top portion of the query). This is set to ten in the example below (query: Other: Top 10 Auto Companies):
Iif, if then else, and select case in ms access
Today’s tutorial will cover the Ms Access Case Statement. Case statements, including if-then-else statements, are used to define and send commands to some conditions. There are two Case Statements: one for determining the result by comparing an expression to a collection of simple expressions, and the other for determining the result by evaluating a set of Boolean expressions.
Condition: Each item was assessed in the order mentioned. When a condition is found to be valid, the Case statement executes the code associated with it and stops evaluating the conditions. Multiple Case Conditions may be used in a single code.
