# WSREP\_SYNC\_WAIT\_UPTO\_GTID

## Syntax

```bnf
WSREP_SYNC_WAIT_UPTO_GTID(gtid[,timeout])
```

## Description

Blocks the client until the transaction specified by the given [Global Transaction ID](/docs/server/ha-and-performance/standard-replication/gtid.md) is applied and committed by the node.

The optional *timeout* argument can be used to specify a block timeout in seconds. If not provided, the timeout will be indefinite.

Returns the node that applied and committed the Global Transaction ID, `ER_LOCAL_WAIT_TIMEOUT` if the function is timed out before this, or `ER_WRONG_ARGUMENTS` if the function is given an invalid GTID.

The result from [WSREP\_LAST\_SEEN\_GTID](/docs/server/reference/sql-functions/special-functions/galera-functions/wsrep_last_seen_gtid.md) can be useful to determine the transaction to provide to `WSREP_SYNC_WAIT_UPTO_GTID` for waiting and unblocking purposes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mariadb.com/docs/server/reference/sql-functions/special-functions/galera-functions/wsrep_sync_wait_upto_gtid.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
