LISTALLCONDITIONAL

Lists values from a table’s column, where specified conditions are met for each row.

Syntax

LISTALLCONDITIONAL( [ Table], [ Column], [ConditionColumn1] , [Condition1] )

The Table is the table from which to retrieve the data.

Column is the number of the column within the table to retrieve the data from.

ConditionColumn is the number of the column within the table to filter the data on.

Condition is an expression that when met will include the data from the column.

Multiple Conditions are separated by a comma and must start with the column number followed by the condition, as below:

[ConditionColumn1] , [Condition1] , [ConditionColumn2] , [Condition2]

There is no limit to the number of ConditionColumn and Condition arguments, although they do need to be used in pairs.

Examples

Meaning

LISTALLCONDITIONAL(Vehicles, 1,3,"=Red")

Or

LISTALLCONDITIONAL(Vehicles, 1,3,"Red")

The function looks in the Vehicles table, and retrieves all the data in the first column where the data in column 3 equals Red. In this case, that first column contains car makes, so the list; "Ford|Mazda" is returned.
LISTALLCONDITIONAL(People, 2,3,">30")The function looks in the People table, and retrieves all the data in the second column where the values in column 3 are greater than 30. In this case, that second column contains Names, so the list; "Joe Bloggs|Sandra Shield|Isabelle Jones" is returned.
LISTALLCONDITIONAL(People, 2,3,">30",4,"Female")The function looks in the People table, and retrieves all the data in the second column where the values in column 3 are greater than 30 and also where the values in column 4 equal Female (note the = symbol is not required). In this case, that second column contains Names, so the list; "Sandra Shield|Isabelle Jones" is returned.
LISTALLCONDITIONAL(Vehicles, 1,3,"=" & ColorReturn)The function looks in the Vehicles table, and retrieves all the data in the first column where the data in column 3 equals the value selected from the Color form control. In this case, that first column contains car makes, so the list; "Ford|Mazda" is returned.
