title: not equals
---

The not equals (`!=`) match filter returns rows that **do not** exactly match the specified value.

## Syntax

```
columnName != value
```

- `columnName` - the column the filter will search for non-matching values.
- `value` - the value to match on.

## Examples

The following example returns rows where `Color` is _not_ `blue`.

```python order=source,result
from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.constants import NULL_INT

source = new_table(
    [
        string_col("Letter", ["A", "C", "F", "B", "E", "D", "A"]),
        int_col("Number", [NULL_INT, 2, 1, NULL_INT, 4, 5, 3]),
        string_col(
            "Color", ["red", "blue", "orange", "purple", "yellow", "pink", "blue"]
        ),
        int_col("Code", [12, 14, 11, NULL_INT, 16, 14, NULL_INT]),
    ]
)


result = source.where(filters=["Color != `blue`"])
```

The following example returns rows where `Color` is _not_ `blue` and `Code` is _not_ 14.

```python order=source,result
from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.constants import NULL_INT

source = new_table(
    [
        string_col("Letter", ["A", "C", "F", "B", "E", "D", "A"]),
        int_col("Number", [NULL_INT, 2, 1, NULL_INT, 4, 5, 3]),
        string_col(
            "Color", ["red", "blue", "orange", "purple", "yellow", "pink", "blue"]
        ),
        int_col("Code", [12, 14, 11, NULL_INT, 16, 14, NULL_INT]),
    ]
)

result = source.where(filters=["Color != `blue`", "Code != 14"])
```

The following example returns rows where `Color` is _not_ `blue` _or_ `Code` is _not_ 14.

```python order=source,result
from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.constants import NULL_INT

source = new_table(
    [
        string_col("Letter", ["A", "C", "F", "B", "E", "D", "A"]),
        int_col("Number", [NULL_INT, 2, 1, NULL_INT, 4, 5, 3]),
        string_col(
            "Color", ["red", "blue", "orange", "purple", "yellow", "pink", "blue"]
        ),
        int_col("Code", [12, 14, 11, NULL_INT, 16, 14, NULL_INT]),
    ]
)

result = source.where_one_of(filters=["Color != `blue`", "Code != 14"])
```
