## How to delete rows from a table
|
||||
|
||||
Use the `delete()` method on tables to delete rows from a table. To choose
|
||||
which rows to delete, provide a filter that matches on the metadata columns.
|
||||
This can delete any number of rows that match the filter.
|
||||
|
||||
=== "Python"
|
||||
```python
|
||||
tbl.delete('item = "fizz"')
|
||||
```
|
||||
|
||||
=== "Javascript"
|
||||
```javascript
|
||||
await tbl.delete('item = "fizz"')
|
||||
```
|
||||
|
||||
The deletion predicate is a SQL expression that supports the same expressions
|
||||
as the `where()` clause on a search. They can be as simple or complex as needed.
|
||||
To see what expressions are supported, see the [SQL filters](sql.md) section.

# Vector embedding search using TransformersJS
|
||||
|
||||
## Embed and query data from LacneDB using TransformersJS
|
||||
|
||||
<img id="splash" width="400" alt="transformersjs" src="https://github.com/lancedb/lancedb/assets/43097991/88a31e30-3d6f-4eef-9216-4b7c688f1b4f">
|
||||
|
||||
This example shows how to use the [transformers.js](https://github.com/xenova/transformers.js) library to perform vector embedding search using LanceDB's Javascript API.
|
||||
|
||||
|
||||
### Setting up
|
||||
First, install the dependencies:
|
||||
```bash
|
||||
npm install vectordb
|
||||
npm i @xenova/transformers
|
||||
```
|
||||
|
||||
We will also be using the [all-MiniLM-L6-v2](https://huggingface.co/Xenova/all-MiniLM-L6-v2) model to make it compatible with Transformers.js
|
||||
|
||||
Within our `index.js` file we will import the necessary libraries and define our model and database:
|
||||
|
||||
```javascript
|
||||
const lancedb = require('vectordb')
|
||||
const { pipeline } = await import('@xenova/transformers')
|
||||
const pipe = await pipeline('feature-extraction', 'Xenova/all-MiniLM-L6-v2');
|
||||
```
|
||||
|
||||
### Creating the embedding function
|
||||
|
||||
Next, we will create a function that will take in a string and return the vector embedding of that string. We will use the `pipe` function we defined earlier to get the vector embedding of the string.
|
||||
|
||||
```javascript
|
||||
// Define the function. `sourceColumn` is required for LanceDB to know
|
||||
// which column to use as input.
|
||||
const embed_fun = {}
|
||||
embed_fun.sourceColumn = 'text'
|
||||
embed_fun.embed = async function (batch) {
|
||||
let result = []
|
||||
// Given a batch of strings, we will use the `pipe` function to get
|
||||
// the vector embedding of each string.
|
||||
for (let text of batch) {
|
||||
// 'mean' pooling and normalizing allows the embeddings to share the
|
||||
// same length.
|
||||
const res = await pipe(text, { pooling: 'mean', normalize: true })
|
||||
result.push(Array.from(res['data']))
|
||||
}
|
||||
return (result)
|
||||
}
|
||||
```
|
||||
|
||||
### Creating the database
|
||||
|
||||
Now, we will create the LanceDB database and add the embedding function we defined earlier.
|
||||
|
||||
```javascript
|
||||
// Link a folder and create a table with data
|
||||
const db = await lancedb.connect('data/sample-lancedb')
|
||||
|
||||
// You can also import any other data, but make sure that you have a column
|
||||
// for the embedding function to use.
|
||||
const data = [
|
||||
{ id: 1, text: 'Cherry', type: 'fruit' },
|
||||
{ id: 2, text: 'Carrot', type: 'vegetable' },
|
||||
{ id: 3, text: 'Potato', type: 'vegetable' },
|
||||
{ id: 4, text: 'Apple', type: 'fruit' },
|
||||
{ id: 5, text: 'Banana', type: 'fruit' }
|
||||
]
|
||||
|
||||
// Create the table with the embedding function
|
||||
const table = await db.createTable('food_table', data, "create", embed_fun)
|
||||
```
|
||||
|
||||
### Performing the search
|
||||
|
||||
Now, we can perform the search using the `search` function. LanceDB automatically uses the embedding function we defined earlier to get the vector embedding of the query string.
|
||||
|
||||
```javascript
|
||||
// Query the table
|
||||
const results = await table
|
||||
.search("a sweet fruit to eat")
|
||||
.metricType("cosine")
|
||||
.limit(2)
|
||||
.execute()
|
||||
console.log(results.map(r => r.text))
|
||||
```
|
||||
```bash
|
||||
[ 'Banana', 'Cherry' ]
|
||||
```
|
||||
|
||||
Output of `results`:
|
||||
```bash
|
||||

Delete rows from this table.

This can be used to delete a single row, many rows, all rows, or

sometimes no rows (if your predicate matches nothing).
|

|
||||
**`Examples`**
|
||||
|
||||
```ts
|
||||
const con = await lancedb.connect("./.lancedb")
|
||||
const data = [
|
||||
{id: 1, vector: [1, 2]},
|

{id: 2, vector: [3, 4]},
|

const tbl = await con.createTable("my_table", data)

await tbl.delete("id = 2")

await tbl.countRows() // Returns 2
|

```
|

If you have a list of values to delete, you can combine them into a

```ts

|
||||
For example, if you have a dataset that is larger than memory size, you can create table with `Iterator[pyarrow.RecordBatch]`,
|
||||
to lazily generate data:
|
||||
|
||||
```py
|
||||
|
||||
from typing import Iterable
|
||||
import pyarrow as pa
|
||||
import lancedb
|
||||
|
||||
def make_batches() -> Iterable[pa.RecordBatch]:
|
||||
for i in range(5):
|
||||
yield pa.RecordBatch.from_arrays(
|
||||
[
|
||||
pa.array([[3.1, 4.1], [5.9, 26.5]]),
|
||||
pa.array(["foo", "bar"]),
|
||||
pa.array([10.0, 20.0]),
|
||||
],
|
||||
["vector", "item", "price"])
|
||||
|
||||
schema=pa.schema([
|
||||
pa.field("vector", pa.list_(pa.float32())),
|
||||
pa.field("item", pa.utf8()),
|
||||
pa.field("price", pa.float32()),
|
||||
])
|
||||
|
||||
table = db.create_table("iterable_table", data=make_batches(), schema=schema)
|
||||
```
|
||||
|
||||
You will find detailed instructions of creating dataset in
|
||||
[Basic Operations](../basic.md) and [API](../python/#lancedb.db.DBConnection.create_table)
|
||||
sections.
|
||||
|
||||
## Vector Search
|
||||
|
||||
We can now perform similarity search via `LanceDB` Python API.

# Pydantic
|
||||
|
||||
[Pydantic](https://docs.pydantic.dev/latest/) is a data validation library in Python.
|
||||
|
||||
## Schema
|
||||
|
||||
LanceDB supports to create Apache Arrow Schema from a
|
||||
[Pydantic BaseModel](https://docs.pydantic.dev/latest/api/main/#pydantic.main.BaseModel)
|
||||
via [pydantic_to_schema()](python.md##lancedb.pydantic.pydantic_to_schema) method.
|
||||
|
||||
::: lancedb.pydantic.pydantic_to_schema
|
||||
|
||||
## Vector Field
|
||||
|
||||
LanceDB provides a [`vector(dim)`](python.md#lancedb.pydantic.vector) method to define a
|
||||
vector Field in a Pydantic Model.
|
||||
|
||||
::: lancedb.pydantic.vector
|
||||
|
||||
## Type Conversion
|
||||
|
||||
LanceDB automatically convert Pydantic fields to
|
||||
[Apache Arrow DataType](https://arrow.apache.org/docs/python/generated/pyarrow.DataType.html#pyarrow.DataType).
|
||||
|
||||
Current supported type conversions:
|
||||
|
||||
| Pydantic Field Type | PyArrow Data Type |
|
||||
| ------------------- | ----------------- |
|
||||
| `int` | `pyarrow.int64` |
|
||||
| `float` | `pyarrow.float64` |
|
||||
| `bool` | `pyarrow.bool` |
|
||||
| `str` | `pyarrow.utf8()` |
|
||||
| `list` | `pyarrow.List` |
|
||||
| `BaseModel` | `pyarrow.Struct` |
|
||||
| `vector(n)` | `pyarrow.FixedSizeList(float32, n)` |

Parameters
|

----------
|

name: str
|

The name of the table.

data: list, tuple, dict, pd.DataFrame; optional
|

The data to insert into the table.
|

schema: pyarrow.Schema; optional
|

The schema of the table.
|

mode: str; default "create"
|
||||
The mode to use when creating the table. Can be either "create" or "overwrite".
|
||||
By default, if the table already exists, an exception is raised.
|
||||
If you want to overwrite the table, use mode="overwrite".
|

on_bad_vectors: str, default "error"
|

What to do if any of the vectors are not the same size or contains NaNs.
|

One of "error", "drop", "fill".
|

fill_value: float
|

The value to use when filling vectors. Only used if on_bad_vectors="fill".
|

|

Note

----
|

The vector index won't be created by default.

To create the index, call the `create_index` method on the table.
