Shifts the bits in the first argument to the left by `n` bits, where `n` is the second argument. Shifting left by `n` positions is equivalent to multiplying the number by `2^n`.
## Syntax
```sql theme={"theme":{"light":"github-light","dark":"github-dark"}}
BIT_SHIFT_LEFT(, )
```
## Parameters
| Parameter | Description | Supported input types |
| :-------- | :---------------------------- | :-------------------- |
| `` | Specifies the value to shift. | `INT`, `BIGINT` |
| `` | The number of bits to shift. | `INT` |
## Return Types
The `BIT_SHIFT_LEFT` function returns a result of either type `INT` or `BIGINT`, depending on the type of the input ``.
## Examples
**Example**
The following code example shifts `0001`, the binary representation of `1`, to the left by two bits, which yields `0100`, the binary representation for `4`:
**Example**
The following code example shifts `00101`, the binary representation of `5`, to the left by two bits, which yields `10100`, the binary representation of `20`:
**Example**
The following code example shifts the binary representation of `-3`, which is `1111111111111101` in signed two's complement, one bit to the left, resulting in `1111111111111010`, the binary signed two's complement of `-6`:
