## Syntax

```
sys.sys_get_config(name,default)
```

## Description

`sys_get_config` is a [stored function](/docs/server/server-usage/stored-routines/stored-functions.md) available with the [Sys Schema](/docs/server/reference/system-tables/sys-schema.md).

The function returns a configuration option value from the [sys\_config table](/docs/server/reference/system-tables/sys-schema/sys-schema-sys_config-table.md). It takes two arguments; *name*, a configuration option name, and *default*, which is returned if the given option does not exist in the table.

Both arguments are `VARCHAR(128)` and can be `NULL`. Returns `NULL` if *name* is `NULL`, or if the given option is not found and *default* is `NULL`.

## Examples

```sql
SELECT sys.sys_get_config('ps_thread_trx_info.max_length',NULL);
+----------------------------------------------------------+
| sys.sys_get_config('ps_thread_trx_info.max_length',NULL) |
+----------------------------------------------------------+
| 65535                                                    |
+----------------------------------------------------------+
```
