The tool name varies based on your configuration:
**Single database without `--id`:**
```bash
npx @bytebase/dbhub --dsn "postgres://..."
```
Tool name: `execute_sql`
**Single database with `--id`:**
```bash
npx @bytebase/dbhub --id prod --dsn "postgres://..."
```
Tool name: `execute_sql_prod`
**Multiple databases via TOML config:**
```toml
[[sources]]
id = "prod-pg"
dsn = "postgres://..."
[[sources]]
id = "staging.mysql"
dsn = "mysql://..."
```
Tool names: `execute_sql_prod_pg` and `execute_sql_staging_mysql`
<Note>
Special characters in source IDs (hyphens, dots, etc.) are converted to underscores in tool names. For example, `prod-pg` becomes `execute_sql_prod_pg`.
