ITER_SQL (SPARQL-Generate for all formats 2.0.12 API)

java.lang.Object
- fr.mines_stetienne.ci.sparql_generate.iterator.IteratorStreamFunctionBase
- - fr.mines_stetienne.ci.sparql_generate.iterator.IteratorStreamFunctionBase2
  - - fr.mines_stetienne.ci.sparql_generate.sql.ITER_SQL

All Implemented Interfaces:

IteratorFunction
```
public class ITER_SQL
extends IteratorStreamFunctionBase2
```
Iterator function SQL issues a SQL query to a database.
- Param 1: (database): the JDBC URI of the database
- Param 2: (sql) the SQL query;
The following variables may be bound:
- Output 1 .. N: value of the ith column, encoded as a boolean, float, double, integer, string, dateTimeStamp, as it best fits.
