[discrete]
[[esql-from]]
=== `FROM`

**Syntax**

[source,esql]
----
FROM index_pattern [METADATA fields]
----

*Parameters*

`index_pattern`::
A list of indices, data streams or aliases. Supports wildcards and date math.

`fields`::
A comma-separated list of <<esql-metadata-fields,metadata fields>> to retrieve.

*Description*

The `FROM` source command returns a table with data from a data stream, index,
or alias. Each row in the resulting table represents a document. Each column
corresponds to a field, and can be accessed by the name of that field.

[NOTE]
====
By default, an {esql} query without an explicit <<esql-limit>> uses an implicit
limit of 500. This applies to `FROM` too. A `FROM` command without `LIMIT`:

[source,esql]
----
FROM employees
----

is executed as:

[source,esql]
----
FROM employees
| LIMIT 500
----
====

*Examples*

[source,esql]
----
FROM employees
----

You can use <<api-date-math-index-names,date math>> to refer to indices, aliases
and data streams. This can be useful for time series data, for example to access
today's index:

[source,esql]
----
FROM <logs-{now/d}>
----

Use comma-separated lists or wildcards to query multiple data streams, indices,
or aliases:

[source,esql]
----
FROM employees-00001,other-employees-*
----

Use the `METADATA` directive to enable <<esql-metadata-fields,metadata fields>>:

[source,esql]
----
FROM employees [METADATA _id]
----
