      • toJdbcType

        public static int toJdbcType​(FieldDescriptor fieldDescriptor)
        Gets the JDBC type value from Types for the field descriptor.
        Parameters:
        fieldDescriptor - Field descriptor
        Returns:
        JDBC type, or Types.OTHER for unknown types

      • isJdbcType

        public static boolean isJdbcType​(FieldDescriptor fieldDescriptor,
                                 int jdbcType)
        Determines if a field descriptor matches a JDBC type value from Types.
        Parameters:
        fieldDescriptor - Field descritpor
        jdbcType - JDBC type
        Returns:
        true if the field descriptor and JDBC type are equivalent (using toJdbcType(FieldDescriptor))

      • fromFirebirdToJdbcType

        public static int fromFirebirdToJdbcType​(int firebirdType,
                                         int subtype,
                                         int scale)
        Converts from the Firebird type, subtype and scale to the JDBC type value from Types.

        This method is not capable of identifying Types.ROWID; this will be identified as Types.BINARY instead.

        Parameters:
        firebirdType - Firebird type value (from ISCConstants SQL_* with or without nullable bit set
        subtype - Subtype
        scale - Scale
        Returns:
        JDBC type, or Types.OTHER for unknown types

        public static int fromMetaDataToJdbcType​(int metaDataType,
                                         int subtype,
                                         int scale)
        Converts from the metadata type (as used in the system tables) to JDBC type values from Types.
        Parameters:
        metaDataType - Metadata type value
        subtype - Subtype
        scale - Scale
        Returns:

      • fromMetaDataToFirebirdType

        public static int fromMetaDataToFirebirdType​(int metaDataType)
        Converts the metadata type value to the Firebird type value (null bit not set).
        Parameters:
        metaDataType - Metadata type value
        Returns:
        Firebird type value
