All standard aggregate functions and available modifiers are listed on this page.
An aggregate function call contains an expression in curly braces ("{}"), which is calculated for the item and all sub-items (or, in some cases, for another subset of related items in the structure), and then the resulting values are aggregated according to the meaning of the aggregate function.
Produces an array of the defined values for the item and/or its sub-items.
Accepts modifiers: #ancestors, #children, #leaves, #strict, #subtree, #fromLevel, #toLevel, #reverse, #distinct (does not include duplicate values), #flatten (if function produces an array, includes the inner values, rather than the array), #compact
Avg calculates an average of the defined values for the item and/or its sub-items. The result for avg is generally the same as sum/count. It returns nothing if there are no defined values for {x}.
If a certain issue (or another kind of item) is included multiple times in the sub-tree, the average value will include the value for that issue only once. This behavior can be overridden by using the #all modifier. |
Accepts modifiers: #all, #children, #leaves, #strict, #subtree, #preceding, #levels (together with #preceding), #baseLevel (together with #preceding).
Count calculates a count of defined values (or truthy values, if the #truthy modifier is specified) for the item and/or its sub-items.
If a certain issue (or another kind of item) is included multiple times in the sub-tree, it will be counted only once. This behavior can be overridden by using the #all modifier. |
Accepts modifiers: #all, #children, #leaves, #strict, #subtree, #truthy, #preceding, #levels (together with #preceding), #baseLevel (together with #preceding).
Returns true if the current row is an issue and it matches this JQL.
This is not an aggregate function; it's an embedded query. We've included it here because it's easy to mistake for an aggregate function - both use curly braces { }. To learn more, see Embedded Queries. |
Join concatenates (joins) strings from the item and its parents (or other items, if modifiers are used).
Accepts modifiers: #ancestors, #subtree, #children, #leaves, #strict, #reverse, #separator, #beforeChildren, #afterChildren, #fromLevel, #toLevel, #distinct.
Max returns the maximum defined value for the item and/or its sub-items. Numeric, date, duration and text fields can be compared. Text fields are compared lexicographically.
If the formula produces an array, this will find the maximum element within that array.
Accepts modifiers: #children, #leaves, #strict, #subtree.
Produces the median value. Works the same as PERCENTILE#0.5.
Undefined are ignored. Non-number values result in an error.
Accepts modifiers: #ancestors, #children, #leaves, #strict, #subtree, #fromLevel, #toLevel
Min returns the minimum defined value for the item and/or its sub-items. Numeric, date, duration and text fields can be compared. Text fields are compared lexicographically.
If the formula produces an array, this will find the minimum element within that array.
Accepts modifiers: #children, #leaves, #strict, #subtree.
Parent extracts the value from the parent row or from an ancestor row by a specified level.
Using the #level modifier, you can specify which row to extract the value from:
PARENT#level=-1{}
extracts the value from the parent row (same as PARENT{})
PARENT#level=-2{}
extracts the value from the grandparent rowPARENT#level=1{}
extracts the value from the root rowAccepts modifier: #level.
Calculates a percentile value from the defined values for the item and/or its sub-items. The hierarchy of values is ignored – all subject values are treated equally.
Must include the modifier #p, followed by the desired percentile (p=0.95, p=95). p=1 interpreted as 1%.
Undefined are ignored. Non-number values result in an error.
Accepts modifiers: #ancestors, #children, #leaves, #strict, #subtree, #fromLevel, #toLevel, #p (required)
Works the same as PERCENTILE#0.25.
Undefined are ignored. Non-number values result in an error.
Accepts modifiers: #ancestors, #children, #leaves, #strict, #subtree, #fromLevel, #toLevel
Works the same as PERCENTILE#0.75.
Undefined are ignored. Non-number values result in an error.
Accepts modifiers: #ancestors, #children, #leaves, #strict, #subtree, #fromLevel, #toLevel
Returns true if the current row matches this S-JQL.
This is not an aggregate function; it's an embedded query. We've included it here because it's easy to mistake for an aggregate function - both use curly braces { }. To learn more, see Embedded Queries. |
Sum calculates a numerical total for the values calculated for the item and/or its sub-items.
Other variations of SUM
allow different types of aggregation:
SUM{}
(the same as SUM#subtree{}
) aggregates values from all descendants SUM#children{}
aggregates values from direct children onlySUM#leaves{}
aggregates values from leavesSUM#preceding{}
aggregates values from the preceding rowsNote that when the value of the expression under aggregation is not numeric (and cannot be converted to a number), it is ignored.
If a certain issue (or another kind of item) is included multiple times in the sub-tree, the sum will include the value for that issue only once. This behavior can be overridden by using the |
Accepts modifiers: #all, #children, #leaves, #preceding, #strict, #subtree, #levels (together with #preceding), #baseLevel (together with #preceding).
Produces an array of all distinct values for the item and/or its sub-items.
If a value is an array, considers each value in the array separately.
Accepts modifiers: #ancestors, #children, #leaves, #strict, #subtree, #fromLevel, #toLevel
Defines the exit separator between children and parent rows. This modifier has a string parameter. The default exit separator is:
|
Can be used with: join.
Tells the aggregate function to include duplicate items. By defaults, functions that count values ignore duplicate items.
|
Can be used with: sum, count, avg.
Only process ancestors of the current row. This is the default behavior for join.
Can be used with: array, join, median, percentile, quartile1, quartile3, values.
Can be used with SUM with the #preceding
modifier to specify at which level the accumulation will be reset and start over from zero. This allows for accruing independent cumulative values in different sub-trees.
SUM#preceding#baseLevel=1{story_points}
will accumulate the Story Points within the scope of each epic independently.Can be used with: avg, count, sum (together with #preceding).
See #afterChildren.
Only process direct children of the current row.
|
Can be used with: array, sum, count, avg, join, min, max, median, percentile, quartile1, quartile3, values.
Ignores undefined values when collecting an array.
This modifier is implicitly turned on by applying the #distinct modifier to the join aggregate function.
Can be used with: array.
Same as #level modifier.
Makes array only produce an array of distinct values. A duplicate value won't be added more than once if this modifier is on.
|
Makes join only concatenate distinct values. A duplicate value won't be added more than once if this modifier is on. When used with arrays, removes undefined values and performs one-step flattening.
Modifiers #beforeChildren and #afterChildren don't work when this option is on.
|
Can be used with: join.
When collecting values from sub-items (or another subset of related items) if a value is an array, includes all the elements instead of just including the array.
This modifier is implicitly turned on by applying the #distinct modifier to the join aggregate function.
Can be used with: array.
Same as #fromLevel.
Specifies the position of the first row the aggregate function should take as input for a sequence.
Position is specified by an integer parameter denoted as n below:
JOIN#fromLevel=0{MIN{due_date}}
will provide a sequence of the earliest due dates, starting from the earliest throughout the whole structure, then the earliest throughout the root tree this item is in, and so on.This modifier does not work with any tree types except #ancestors.
|
Can be used with: array, join, median, percentile, quartile1, quartile3, values.
Only process leaves (items without children) in the subtree of the current row.
|
Can be used with: array, sum, count, avg, join, min, max, median, percentile, quartile1, quartile3, values.
When used with PARENT, specifies the position of the parent that possesses value.
Position is specified by an integer parameter denoted as n below:
PARENT#level=0{SUM{story_points}}
means total story points for the whole structure (including subtrees for all roots).When used with SUM with the #preceding
modifier, this specifies the level at which the values should be aggregated.
|
Can be used with: parent, sum (together with #preceding), count (together with #preceding), avg (together with #preceding).
Can be used with SUM with the #preceding
modifier to specify at which levels should the accrual of the values happen.
SUM#preceding#levels=1{story_points}
will accumulate Story Points from top to bottom at level 1.SUM#preceding#levels="2,4"{time_spent}
will accumulate Time Spent on levels 2 and 4.Note that if you use the #baseLevel modifier, only values at levels that are deeper than the base level will be counted.
You can also use #level instead of #levels.
Can be used with: avg, count, sum (together with #preceding).
Can be used with SUM to calculate a numeric total of the current item and all items above it in the structure.
Can be combined with the following modifiers:
|
Can be used with: sum.
Reverses the order of row processing.
|
Can be used with: array, join.
Defines the separator for string joining. This modifier has a string parameter. The default is ", ".
|
Can be used with: join.
Do not process the current row item as part of the aggregation.
Cannot be used together with #children, #ancestors or #leaves, since these already exclude the current row.
|
Can be used with: array, sum, count, avg, join, min, max, median, percentile, quartile1, quartile3, values.
Process the whole subtree of the current row. This is the default behavior for sum, count, avg, min, max.
|
Can be used with: array, sum, count, avg, join, min, max, median, percentile, quartile1, quartile3, values.
Same as #toLevel.
Specifies the position of the last row the aggregate function should take as input for a sequence.
Position is specified by an integer parameter denoted as n below:
This modifier does not work with any tree types except #ancestors.
|
Can be used with: array, join, median, percentile, quartile1, quartile3, values.
Only count row if the subexpression produces a truthy value .
|
Can be used with: count.
