Parameter Properties

This topic describes the properties of a Parameter object in a catalog.

Property Name Description
General
Allow Showing Unencrypted Value Specifies whether to display the "Hide Parameter Value" option in the UI for specifying the parameter value to allow users to view the unencrypted values of the parameter after the values are encrypted.

Data type: Boolean
Bind Column Specifies the bind column of the parameter.

Data type: String
Binding Specifies the parameter to bind with the current parameter to sort the column controlled by the current parameter.

Data type: String
Default Value Number Specifies the parameter value to be prompted by default at runtime. Set the property value to 0 if you want to prompt the first parameter value that you specify for the parameter; set the property value to -1 to prompt the last parameter value.

Data type: Integer
Description Specifies the description of the object.

Data type: String

Display Column Specifies the display column of the parameter.

Data type: String
Display Width Specifies the display width of the object, which takes effect when you insert the object into reports. Type a numeric value to change the width. If you do not set the display width, Designer applies a default width to it automatically.

Data type: Float

Note icon After you set the Display Width of an object and use the object while creating a data component with wizard, Designer may adjust its width according to the paper size.
Distinct Specifies whether to display identical values only once in the UI for specifying the parameter value.

Data type: Boolean
Encrypt Parameter Value Specifies whether to encrypt values of the parameter in the UI where the parameter is used or required (excluding parameter control and parameter form control) and in log files. However, if you bind the parameter with a column or set its Allow Multiple Values property to "true", Logi Report Engine only encrypts its values in log files.

Note icon When writing the value of a formula or string that references a encrypted parameter to log, Logi Report Engine may not encrypt the parameter value.

Data type: Boolean
Get Value from API Only Specifies whether the parameter values can only be specified using API.

If you set the property to "true", users should obtain parameter values only from API and there is no parameter dialog boxes available on any Designer or Server UI for inputting values. Users have to give the values of the parameter by API such as URLs, coding, and sessions; otherwise. Logi Report Engine applies the default value of the parameter.

If you set the property to "false", the parameter values can be obtained from both GUI and API.

If a member of a cascading parameter group can get values from API only, it means that all the higher level members shall get values from API only. This also applies to parameters on which other parameters depend. If several parameters share values in JDashboard, when any of them can get values from API only, they will share the values from API.

Data type: Boolean
Hide Parameter When Single Value Returned Specifies whether to hide the parameter at runtime when only a single value is returned for it.

If you bind a parameter with a column, you can hide the parameter at runtime when only a single value is returned for the parameter. Logi Report Engine then applies the returned single value as the default value of the parameter. This can be very useful for security. For example, you can use a parameter bound with a DBField such as UserID and if there is one to one mapping of UserID to the Logi Report Server users, then a query for a parameter such as Select UserID FROM Employees WHERE UserID = @username would just return a single value and thus you can use it as a filter for any other queries you create.

Data type: Boolean
Import SQL Specifies the SQL statement for retrieving values of the bound column and display column for the parameter. You can use the special field "User Name" in the SQL statement as @username.

Data type: String

Note icon Once you edit the SQL statement, the later changes to the Bind Column and Display Column properties cannot take effect unless you remove the SQL lines or bind column to the parameter all over again using dialog box.
Maximum Value/Length Specifies the maximum value allowed for the parameter, or the maximum length for a String type parameter.

Data type: String
Minimum Value/Length Specifies the minimum value allowed for the parameter, or the minimum length for a String type parameter.

Data type: String
Name Specifies the mapped name of the object in the catalog.

Data type: String

Object Name Specifies the name of the OOJDBC class related to the parameter.

Data type: String
Object Parameter Name Specifies the parameter name for the OOJDBC class.

Data type: String
Operation Specifies whether to check the minimum and maximum values specified for the parameter at runtime. If you want to perform the check, set the property value to -1; otherwise, set it to 1.

Data type: Integer
Prompt Text Specifies the text for prompting users to provide the value of the parameter.

To help users avoid typing a value out of range, you can add the value range to the end of the prompt text, for example, "Type a customer ID (1~100):"; to help users avoid typing a value in a wrong pattern, you can add the value pattern to the end of the prompt text, for example, "Type an order date (MMM-dd-yy):".
Record Level Security Specifies the record level security to apply to the parameter.

If you bind a parameter with a column, you can specify a RLS policy defined on the bound column to the parameter, then at runtime, the specified security identifier only sees the records it is allowed to view in the parameter value drop-down list. See Applying RLS to a Parameter for an example.

Data type: String
Required Specifies whether the parameter is a required parameter.

A required parameter must be fulfilled, meaning, users must supply a value for the parameter before they can run the report. If you set the option to "false", the parameter is an optional parameter. The value of an optional parameter can be blank, which means users can either type a value, or leave it as it is. In the dialog box for specifying the parameter value, Logi Report marks the prompt text of a required parameter with the "*" symbol.

Data type: Boolean

Critical icon If a parameter is optional and you do not expect it to take effect in the report, when specifying the parameter value, you should clear the content in the value text box. Any value left in the text box functions in the report.
String Encoding Specifies the encoding for the parameter if the parameter is of the String type.

Data type: String
String Format Specifies the user-defined format for the values of the parameter if the parameter is of the String type.

Data type: String
Treat Blank as Null Specifies whether to treat blank value as null for the parameter if the parameter is of the String type.

Data type: Boolean
Use Current Date-Time Specifies whether to use the current system's date time as value of the parameter when the parameter's data type is Date, Time, or DateTime.

Data type: Boolean
Use Current Date-Time When Blank Specifies whether to use the current system's date time as value of the parameter when the parameter's data type is Date, Time, or DateTime, and the parameter value is blank.

Data type: Boolean
User Defined Format Specifies the user-defined format for the values of the parameter.

For certain types of parameters, the value format supplied by Logi Report may not satisfy your requirement. In this case, you can define your own preferred format. Once you define the value format, all the values supplied for the parameter at runtime should be based on it; otherwise, there is an error message.

Data type: String
Value List Shows values of the parameter. This property is read only.
Value Type Specifies the data type of the parameter. Choose an option from the drop-down list.

Data type: Enumeration
Text Format
Auto Fit Specifies whether to automatically adjust the width and height of the object according to its content.

Data type: Boolean
Auto Scale in Number Designer displays this property when the object is Number data type. You can use it to specify whether to automatically scale values of the object that fall into the two ranges:
  • When 1000 <= value < 10^15, Designer applies the following quantity unit symbols of the International System of Units to scale the values: K (10^3), M (10^6), G (10^9), and T (10^12).
  • When 0 < value < 0.001 or value >= 10^15, Designer uses scientific notation to scale the values.

The option "auto" means that the property setting follows that of the parent data component when you use the object in a report.

Data type: Boolean
Bold Specifies whether to apply bold style to the text in the object.

Data type: Boolean
Font Face Specifies the font face of the text in the object. Choose an option from the drop-down list.

Data type: Enumeration

Format Specifies the format in which you want to display values of the object in the report result. Choose an option from the drop-down list or type the format by yourself.

Data type: String

Note icon If the object is BigDecimal data type, to avoid precision loss, you should specify a prefix JRD when setting the format.
Horizontal Alignment Specifies the horizontal justification of the text in the object. Choose an option from the drop-down list.

Data type: Enumeration
Italic Specifies whether to italicize the text in the object.
