Interface OracleParameterMetaData

  • All Superinterfaces:
    java.sql.ParameterMetaData, java.sql.Wrapper
    public interface OracleParameterMetaData
extends java.sql.ParameterMetaData
    This interface defines the Oracle extensions to the standard JDBC interface java.sql.ParameterMetaData. For pre-JDK 1.4 applications, this interface provides the equivalent functions in java.sql.ParameterMetaData. Applications can use java.sql.ParameterMetaData where they do not make use of Oracle extensions. However, when an application uses the Oracle extensions to java.sql.ParameterMetaData, it must use oracle.jdbc.OracleParameterMetaData.

    This is an interface that can be used to get information about the types and properties of the parameters in a PreparedStatement object.

      • getScale

        int getScale​(int param)
      throws java.sql.SQLException
        Gets the designated column's number of digits to the right of the decimal point.

        An Oracle NUMBER data type can be defined with a scale that ranges from -84 to 127. When the scale is not specified, the special value -127 will be returned by this method. It has no other meaning than to indicate that the scale isn't set.

        For data types that don't have a scale, the value 0 is returned.

        Specified by:
        getScale in interface java.sql.ParameterMetaData
        Parameters:
        param - the first parameter is 1, the second is 2, ...
        Returns:
        scale
        Throws:
        java.sql.SQLException - if a database access error occurs
