# uniqThetaSketch {#agg_function-uniqthetasketch}
Calculates the approximate number of different argument values, using the [Theta Sketch Framework](https://datasketches.apache.org/docs/Theta/ThetaSketchFramework.html).
``` sql
uniqThetaSketch(x[, ...])
```
**Arguments**
The function takes a variable number of parameters. Parameters can be `Tuple`, `Array`, `Date`, `DateTime`, `String`, or numeric types.
**Returned value**
- A [UInt64](../../../sql-reference/data-types/int-uint.md)-type number.
**Implementation details**
Function:
- Calculates a hash for all parameters in the aggregate, then uses it in calculations.
- Uses the [KMV](https://datasketches.apache.org/docs/Theta/InverseEstimate.html) algorithm to approximate the number of different argument values.
4096(2^12) 64-bit sketch are used. The size of the state is about 41 KB.
- The relative error is 3.125% (95% confidence), see the [relative error table](https://datasketches.apache.org/docs/Theta/ThetaErrorTable.html) for detail.
