JdbcNumericBetweenParametersProvider (SeaTunnel : Connectors V2 : Jdbc 2.3.7 API)

java.lang.Object
- org.apache.seatunnel.connectors.seatunnel.jdbc.internal.split.JdbcNumericBetweenParametersProvider

所有已实现的接口:

JdbcParameterValuesProvider
```
public class JdbcNumericBetweenParametersProvider
extends Object
implements JdbcParameterValuesProvider
```
This query parameters generator is an helper class to parameterize from/to queries on a numeric column. The generated array of from/to values will be equally sized to fetchSize (apart from the last one), ranging from minVal up to maxVal.
For example, if there's a table BOOKS with a numeric PK id, using a query like:
```
 SELECT * FROM BOOKS WHERE id BETWEEN ? AND ?
 
```
You can take advantage of this class to automatically generate the parameters of the BETWEEN clause, based on the passed constructor parameters.
