Data group action - Filter expression

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, text
Operator	Delivers
Operator	Delivers
Equal to	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 start with 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 field is 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, double, datetime
Operator	Delivers
Equal to	Equal values
Unequal	Unequal values
Less than or equal	Smaller or equal values
Less than	Smaller values
Greater than or equal	Exceeding or equal values
Greater than	Exceeding values
Undefined	Every data set 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. 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. More information about this topic can be found here.

Data type: boolean
Operator	Delivers
Equal to	Equal logical value
Undefined	Fields with the value "NULL"
Defined	Records in which the data field has 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.

Comparative 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.

Request value

Compares the data field with the value of a request variable that is entered here.

Value

Enter the name of the request parameter here.

Default

Enter the default value that should be used for null values.

Session value

Compares the data field with the value of a session variable.

Value

Enter the name of the session variable here.

Default

The default value is used when the session variable is not defined.

Processing context

Compares the data field with the value of a variable from the processing context.

Value

Enter the name of the variable here.

Default

The default value is used when the variable is not defined.

Set

In combination with the operator "Is contained in", this delivers data records from users who are contained in the set. Only users are retrieved, other objects like user groups are not.

Set

Select the desired set.

Containers

In combination with the operator "Is contained in", this delivers data records from users who are contained in the container.

Containers

Select the desired container.

Selected tenants of current user

In combination with the operator "Is contained in tenants", this returns the records that are contained in the tenants selected by the current user. More information about this topic can be found here.

All tenants of current user

In combination with the operator "Is contained in tenants", this returns the records that are contained in every tenant assigned to the current user. More information about this topic can be found here.

System value - Comparison with a "datetime" data field

If the selected data field is a "datetime" data field, the value of that field can be compared with the current date. You can find out more about adjusting dates here.

Please note when filtering time periods that a day always begins at 00:00. So if you want to filter the period 8/1 to 8/5, the filter expression must be ">8/1 and <8/6" so that 8/5 is still included in the filter.

System value - Comparison with a string or text data field

String or text data fields can be compared with the system value "exchange mailbox info". Possible values:

INBOX

(HRef of the folder inbox)

USERMAILADDRESS

(Email address of the exchange user)

USERMAILBOX

(Mailbox of the exchange user)

DRAFTS

(HRef of the folder drafts)

DELETEDITEMS

(HRef of the folder deleted items)

SENTITEMS

(HRef of the folder sent items)

CALENDAR

(HRef of the folder calendar)

CONTACTS

(HRef of the folder contacts)

TASKS

(HRef of the folder tasks)

VERSION

(Version of the Exchange server in the Exchange configuration)

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. In the API environment, API parameters can also be used for the comparison.

Default

Enter the name of the binding here.

Custom

Any character string can be entered as a user-defined, static comparison value to compare string data fields. Please note that these are case-sensitive. For integer or double data fields, you can compare with any number. "Datetime" data fields can be compared with a date.

Subquery

This comparison value can be selected in combination with the operators "Is contained in" or "Is not contained in" and also with dependencies.

Edit subquery

Opens a dialog where the subquery for a data group can be defined.
