# skript-db

 > Sensible SQL support for Skript.
---

### Effect `Execute Statement`
Executes a statement on a database and optionally stores the result in a variable. Expressions
 embedded in the query will be escaped to avoid SQL injection.
 <p>
 If a single variable, such as `{test}`, is passed, the variable will be set to the number of
 affected rows.
 <p>
 If a list variable, such as `{test::*}`, is passed, the query result will be mapped to the list
 variable in the form `{test::<column name>::<row number>}`

 Specifying `synchronously` will make skript-db execute the query on the event thread, which is useful for async
 events. Note that skript-db will ignore this flag if you attempt to run this on the main thread.
#### Syntax
```
[synchronously] execute %string% (in|on) %datasource% [and store [[the] (output|result)[s]] (to|in) [the] [var[iable]] %-objects%]
```

#### Examples
```
execute "select * from table" in {sql} and store the result in {output::*}
```
```
execute "select * where player=%{player}%" in {sql} and store the result in {output::*}
```

### Expression `Last Data Source Error` => `text`
Stores the error from the last executed statement, if there was one.
#### Syntax
```
[the] [last] (sql|db|data(base|[ ]source)) error
```

---

### Expression `Unsafe Expression` => `text`
Opts out of automatic SQL injection protection for a specific expression in a statement.
#### Syntax
```
unsafe %text%
```

#### Examples
```
execute "select %unsafe {columns variable}% from %{table variable}%" in {sql}
```
```
execute unsafe {fully dynamic query} in {sql}
```

---

### Expression `Data Source` => `datasource`
Stores the connection information for a data source. This should be saved to a variable in a
 `script load` event or manually through an effect command.

 The url format for your database may vary! The example provided uses a MySQL database.
#### Syntax
```
[the] data(base|[ ]source) [(of|at)] %string% [with [a] [max[imum]] [connection] life[ ]time of %timespan%]"
```

#### Examples
```
set {sql} to the database "mysql://localhost:3306/mydatabase?user=admin&password=12345&useSSL=false"
```
