# IN Operator / CONTAINSROW function

Returns TRUE if a row of values exists or contained in a table, otherwise returns FALSE. Except syntax, the IN operator and CONTAINSROW function are functionally equivalent.

## IN Operator

### Syntax

``````<scalarExpr> IN <tableExpr>
( <scalarExpr1>, <scalarExpr2>, … ) IN <tableExpr>

``````

## CONTAINSROW function

### Syntax

``````CONTAINSROW(<tableExpr>, <scalarExpr>[, <scalarExpr>, …])
``````

### Parameters

Term Definition
scalarExprN Any valid DAX expression that returns a scalar value.
tableExpr Any valid DAX expression that returns a table of data.

TRUE or FALSE.

## Remarks

The number of scalarExprN must match the number of columns in tableExpr.

Unlike the = operator, the IN operator and the CONTAINSROW function perform strict comparison. For example, the BLANK value does not match 0.

NOT IN is not an operator in DAX. To perform the logical negation of the IN operator, put NOT in front of the entire expression. For example, NOT [Color] IN { "Red", "Yellow", "Blue" }.

## Examples

### Example 1

The following equivalent DAX queries:

``````EVALUATE FILTER(ALL(DimProduct[Color]), [Color] IN { "Red", "Yellow", "Blue" })
ORDER BY [Color]
``````

and

``````EVALUATE FILTER(ALL(DimProduct[Color]), ([Color]) IN { "Red", "Yellow", "Blue" })
ORDER BY [Color]
``````

and

``````EVALUATE FILTER(ALL(DimProduct[Color]), CONTAINSROW({ "Red", "Yellow", "Blue" }, [Color]))
ORDER BY [Color]
``````

Return the following table with a single column:

DimProduct[Color]
Blue
Red
Yellow

### Example 2

The following equivalent DAX queries:

``````EVALUATE FILTER(SUMMARIZE(DimProduct, [Color], [Size]), ([Color], [Size]) IN { ("Black", "L") })
``````

and

``````EVALUATE FILTER(SUMMARIZE(DimProduct, [Color], [Size]), CONTAINSROW({ ("Black", "L") }, [Color], [Size]))
``````

Return:

DimProduct[Color] DimProduct[Size]
Black L

### Example 3

The following equivalent DAX queries:

``````EVALUATE FILTER(ALL(DimProduct[Color]), NOT [Color] IN { "Red", "Yellow", "Blue" })
ORDER BY [Color]
``````

and

``````EVALUATE FILTER(ALL(DimProduct[Color]), NOT CONTAINSROW({ "Red", "Yellow", "Blue" }, [Color]))
ORDER BY [Color]
``````

Return the following table with a single column:

DimProduct[Color]
Black
Grey
Multi
NA
Silver
Silver\Black
White
