# DatabaseTransactionCommit

Completes transaction execution.

```
bool  DatabaseTransactionCommit(
   int  database      // database handle received in DatabaseOpen
   );

```

Parameters

database

[in]  Database handle received in [DatabaseOpen()](/en/docs/database/databaseopen).

Return true if successful, otherwise false. To get the error code, use GetLastError(), the possible responses are:

- ERR_INTERNAL_ERROR (4001)                   –  critical runtime error;
- ERR_INVALID_PARAMETER (4003)              –  sql parameter contains an empty string;
- ERR_NOT_ENOUGH_MEMORY (4004)          –  insufficient memory;
- ERR_WRONG_STRING_PARAMETER (5040)  – error converting a request into a UTF-8 string;
- ERR_DATABASE_INTERNAL (5120)              – internal database error;
- ERR_DATABASE_INVALID_HANDLE (5121)   – invalid database handle;
- ERR_DATABASE_EXECUTE (5124)               –  request execution error.

Note

The DatabaseTransactionCommit() function completes all transactions executed after calling the [DatabaseBeginTransaction()](/en/docs/database/databasetransactionbegin) function. Any transaction should start with calling DatabaseTransactionBegin() and end with calling DatabaseTransactionCommit() for successful completion.
