In SQL Server Reporting Services (SSRS), a case statement is a control flow expression that allows you to evaluate a series of conditions and return a result based on the first condition that is met. A case statement is similar to an if-else statement in other programming languages.
Here is an example of a simple case statement in SSRS:
=SWITCH(Fields!Status.Value = “Pending”, “Pending”,
Fields!Status.Value = “Approved”, “Approved”,
Fields!Status.Value = “Rejected”, “Rejected”,
TRUE, “Other”)
This case statement will evaluate the value of the “Status” field, and return “Pending” if the value is “Pending”, “Approved” if the value is “Approved”, “Rejected” if the value is “Rejected”, and “Other” for all other values.
Case statements can be useful for controlling the display of data based on certain conditions and providing more meaningful results to the user.
