[Click here for more information about build tags / constraints.](https://golang.org/pkg/go/build/#hdr-Build_Constraints)
### Usage
If you wish to build this library with additional extensions / features.
Use the following command.
```bash
go build --tags "<FEATURE>"
```
For available features see the extension list.
When using multiple build tags, all the different tags should be space delimted.
Example:
```bash
go build --tags "icu json1 fts5 secure_delete"
```
### Feature / Extension List
| Extension | Build Tag | Description |
|-----------|-----------|-------------|
| Additional Statistics | sqlite_stat4 | This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table.<br><br>The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.<br><br>SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.<br><br>The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |

- Can't build go-sqlite3 on windows 64bit.
> Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
