    • getSqlType

      public Integer getSqlType()

    • setSqlType

      public void setSqlType(Integer sqlType)
      Sets the java.sql.Types code used to bind the example value, or null to let the driver infer it.

    • getExampleValueExpression

      public String getExampleValueExpression()
      Returns the DataPipeline expression whose result, converted to the Java type, is the example value; null means a null value.

    • setExampleValueExpression

      public JdbcQueryParameter setExampleValueExpression(String exampleValueExpression)
      Sets the DataPipeline expression whose result, converted to the Java type, is the example value; null means a null value.

    • getExampleValue

      public Object getExampleValue() throws Throwable
      Evaluates the example value expression and converts the result to the Java type; returns null if there is no expression.
      Throws:
      Throwable

    • toRecord

      public Record toRecord()
      Description copied from interface: RecordSerializable
      Converts this object's state to a record that RecordSerializable.fromRecord(Record) can load.
      Specified by:
      toRecord in interface RecordSerializable
      Overrides:
      toRecord in class Bean

    • fromRecord

      public JdbcQueryParameter fromRecord(Record source)
      Description copied from interface: RecordSerializable
      Loads this instance's state from a record and returns this (for fluid API call chaining). For fluid API call chaining, the overridden method should change the declared return type to its class.
