## org.springframework.jdbc.core
Class SqlInOutParameter

    java.lang.Object
      org.springframework.jdbc.core.SqlParameter
          org.springframework.jdbc.core.ResultSetSupportingSqlParameter
              org.springframework.jdbc.core.SqlOutParameter
                  org.springframework.jdbc.core.SqlInOutParameter

    public class SqlInOutParameter

extends SqlOutParameter

Subclass of `SqlOutParameter` to represent an INOUT parameter. Will return `true` for SqlParameter's `isInputValueProvided()` test, in contrast to a standard SqlOutParameter.

Output parameters - like all stored procedure parameters - must have names.

Since:
  2.0

`SqlInOutParameter(String name, int sqlType, RowCallbackHandler rch)` Create a new SqlInOutParameter.
`SqlInOutParameter(String name, int sqlType, RowMapper rm)` Create a new SqlInOutParameter.
`SqlInOutParameter(String name, int sqlType, String typeName)` Create a new SqlInOutParameter.
`SqlInOutParameter(String name, int sqlType, String typeName, SqlReturnType sqlReturnType)` Create a new SqlInOutParameter.

Method Summary
`boolean` | `isInputValueProvided()` This implementation always returns `true`.
