Filter definitions

Join

If you create multiple filter expressions, the type of "Join" is selectable. An "AND" linking will return only data records that fulfill all criteria, and an "OR" linking will return only the data records that fulfill a minimum of one criterion.

Data group

First, select the data group, from which the values are to be filtered. The filter can also use data fields from a higher or lower data group level, i.e. parent or child data groups.

Data field

Select the data field or reference field whose values should be compared to the selected operation with the comparison value corresponding.

Operation

Select the operator here. Depending on the type of data field selected, the following operators are available:

Data type: string, longtext
Operator	Delivers
Operator	Delivers
Equals	Every string that is identical with the comparative value. This is case-sensitive.
Unequal	Every string that is not identical with the comparative value. This is case-sensitive.
Less than or equal	Every string with a smaller or equal character values (ASCII) as the comparative value.
Less than	Every string with a smaller character values (ASCII)as the comparative value.
Greater than or equal	Every string with a greater or equal character values (ASCII) as the comparative value.
Greater than	Every string with a greater character values (ASCII) as the comparative value.
Undefined	Every data record whose data field does not contain a valid value or has not yet been initialized. A comparative value does not need to be defined for this operator.
Defined	The data field contains any random value. An empty string is also valid - e.g. when saving without an entry. A comparative value does not need to be defined for this operator.
Contains	All string that contain the comparative value.
Starts with	All string that contain the comparative value.
Ends with	All string that end the comparative value.
Is contained in	All strings that appear, even in part, in the comparative value. If the string delivered by the data fieldis identical to the comparative value, no result will be returned. Multiple values can be separated with ||.
Is not contained in	All strings that not appear, even in part, in the comparative value. Multiple values can be separated with ||.

The operators "Less than or equal", "Less than", "Greater than orequal", and "Greater than" offer special usefulness when filtering customer or product numbers that are made up of number and letter strings. With the number "C1000" the ASCII value of the character string can deliver smaller numbers. The capital letter "C" has an ASCII value of 67, the number "1" has the value 49, and the number "0" has the value 48. The operators named above compare ASCII values lexicographically. With the operator "Less than", all numbers that are smaller than "C1000" will be returned ("C999, C998, "etc.). In order to deliver data sets that possess no entry in the data field, a query must be made with an "OR" link, i.e. whether the value of the field is "NULL" (operator: "Undefined"), or whether the entry is empty because no entry has been saved. In order to return an empty string, select the operator "Equals" and set the comparison value to "User-defined". The "Character string" field will remain empty in this case. If all fields will be filtered to return entries (no empty string and no "NULL"), the filter must be run in this way with an "AND" linking.

Data type: integer, float, datetime
Operator	Delivers
Equals	Equal values
Unequal	Unequal values
Smaller than, or equal	Smaller or equal values
Less than	Smaller values
Exceeding, or equal	Exceeding or equal values
Exceeding	Exceeding values
Undefined	Every data set whose data fielddoes not contain a valid value or has not yet been initialized. A comparative value does not need to be defined for this operator.
Defined	The data field contains any random value. A comparative value does not need to be defined for this operator.
Is contained in	The same as operator "Equals"
Is not contained in	The same as operator "Unequal"
Is contained in tenants	Is only available for selection if the UserID or a GUID from the Users application has been selected as the data field. It can be compared with the system values "Selected tenants of current user" and "All tenants of current user" to filter the current data by the tenant(s) that area assigned to the current user.

Data type: boolean
Operator	Delivers
Equals	Equal logical value
Undefined	Fields with the value "NULL"
Defined	Records in which the data fieldhas either the value "True" or "False".

Negation

This setting can be activated for the operators "Contains", "Begins with", and "Ends with". This will identify all data fields that do not match the filter. This will identify all data fields that do not match the filter.

Comparison value

Data field

Here, a data or reference field of your choice can be chosen for comparison. Comparing fields is only possible with fields of the same data type. Comparing fields is only possible with fields of the same data type.

Current value

Returns every data record that contains the current value of the selected data field from the specified ReadContainer.

Select a data field from a parent data group

Opens a dialog where data fields from a parent data group can be selected. This button is only available if the data group, which is used in the selected ReadContainer and has a parent data group (or higher).

Current user - Comparison with an integer data field

• User ID
  

  Compares the ID of the current user for example for showing the records created by the currently logged-in user.

• Gender
  

  Compares with the gender of the currently logged-in user.

• Deputy ID
  

  Together with the operator "Is contained in", a list of the deputy IDs of the current user will be delivered.

• Superior ID
  

  Together with the operator "Is contained in", a list of the superior IDs of the current user will be delivered.

Current user - Comparison with other data types

If a data field is selected that does not have the type integer, a comparison can be made here with the corresponding fields from the User manager.

System value

• Data record ID
  

  The selected data field will be compared with the ID of the currently displayed data record.

• Parent data record ID
  

  The selected data field will be compared with the ID of the superordinate data record.

The comparison value "Language" will filter the table entries depending on the language setting of the portal. A requirement of this is that all data fields that will be compared must have a language key (such as "de", "en") for every data record. The comparison value "Layout" will filter the table entries depending on the current layout of the portal.

Binding

You can compare the value of the date field with session values, request values, values from the processing context, system data fields or parameters. Values can only be compared with parameters in applications. Parameters cannot be selected as the comparison value in processes.

Default

Enter the name of the binding here.

User-defined

As user-defined, static comparison values, any character string can be entered to compare string data fields. Please note that casesensitivity will be considered here. Integer and float data fields can be compared with a number. Datetime data fields can be compared with a date.

Filter

This comparison value can be selected when either "Is contained in" or "Is not contained in"is defined as the operator.
