# Data types
|
|
|
|
The following table shows the data types supported by the PPL plugin and how each one maps to OpenSearch and SQL data types:
|
|
|
|
PPL Type | OpenSearch Type | SQL Type
|
|
:--- | :--- | :---
|
|
boolean | boolean | BOOLEAN
|
|
byte | byte | TINYINT
|
|
byte | short | SMALLINT
|
|
integer | integer | INTEGER
|
|
long | long | BIGINT
|
|
float | float | REAL
|
|
float | half_float | FLOAT
|
|
float | scaled_float | DOUBLE
|
|
double | double | DOUBLE
|
|
string | keyword | VARCHAR
|
|
text | text | VARCHAR
|
|
timestamp | date | TIMESTAMP
|
|
ip | ip | VARCHAR
|
|
timestamp | date | TIMESTAMP
|
|
binary | binary | VARBINARY
|
|
struct | object | STRUCT
|
|
array | nested | STRUCT
|
|
|
|
In addition to this list, the PPL plugin also supports the `datetime` type, though it doesn't have a corresponding mapping with OpenSearch.
|
|
To use a function without a corresponding mapping, you must explicitly convert the data type to one that does.
|
|
|
|
The PPL plugin supports all SQL date and time types. To learn more, see [SQL Data Types]({{site.url}}{{site.baseurl}}/search-plugins/sql/datatypes/).
