How do you deal with multivalued parameters?
Setting default values for multi-value parameters If we want to set Select All option as a default parameter we need to follow the steps below: Choose Get values from a query under the Default Values tab. Set HRReportParameterDataset into the Dataset Combobox. Set JobTitle field into the Value field.
How do you pass multiple values in one parameter?
Possible ways are:
- usage of Table Valued Parameter – wherein you have the i’d to be passed as entries of a table and pass this table itself as input to the SP.
- Another way is to pass in the values as a CSV string which can then be embedded into the query and executed as a dynamic query.
Which tag is used for multi value parameters?
Displaying a Multi-Valued Parameter collection. However, usage of the JOIN() function is required when the parameter allows multiple values. (Note that either Value or Label could be used in the expression.
How we can make attributes have multiple values?
Attribute Element (Handling Multiple Values)
- use a “primitive attribute” and append, with a separator character, the multiple values into one string, or.
- use the FME attribute list, or.
- retain one attribute value out of the multiple values.
How do I cascade parameters in SSRS?
Steps to Create Cascaded Parameters in SSRS
- Step 1: Create your data source connection.
- Step 2: Create Dataset for your Report.
- Step 3: Create Datasets for Parameters.
- Step 4: Set available values for Report Parameters.
- Step 5: Parameter Dataset Modification.
- Step 6: Test the Cascaded parameter.
- Step 7: Add Report items.
What are cascading parameters?
Cascading parameters provide a way of managing large amounts of report data. You can define a set of related parameters so that the list of values for one parameter depends on the value chosen in another parameter. For example, the first parameter is independent and might present a list of product categories.
How do I add a subreport in SSRS?

- Right-click the subreport, and then click Subreport Properties.
How do I make parameters optional in SSRS?

The SSRS Report Parameters allows the users to enter a specific value in the textBox and then, SSRS will filter the Report data using the user-specified value. OR Report Parameters enables the users to Filter the SSRS Reports Dynamically.
What is query parameter in SSRS?
When you define a dataset query that contains a query variable, the query command is parsed. For each query variable, a corresponding dataset parameter and report parameter are created. The dataset parameter points to the report parameter. This enables a user to enter a value that passes directly to the query.
How do you handle null values in SSRS expression?

What is null in C?
Null is a built-in constant that has a value of zero. It is the same as the character 0 used to terminate strings in C. Null can also be the value of a pointer, which is the same as zero unless the CPU supports a special bit pattern for a null pointer.

In C programming language a Null pointer is a pointer which is a variable with the value assigned as zero or having an address pointing to nothing. So we use keyword NULL to assign a variable to be a null pointer in C it is predefined macro.
How do you declare null?

Nullable i = null; A nullable type can represent the correct range of values for its underlying value type, plus an additional null value.
