Interface LoaderRowsStep<R extends Record>


  • public interface LoaderRowsStep<R extends Record>
    The Loader API is used for configuring data loads.

    The step in constructing the Loader object where you can set the mandatory row loader options.

    Referencing XYZ*Step types directly from client code

    It is usually not recommended to reference any XYZ*Step types directly from client code, or assign them to local variables. When writing dynamic SQL, creating a statement's components dynamically, and passing them to the DSL API statically is usually a better choice. See the manual's section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.

    Drawbacks of referencing the XYZ*Step types directly:

    • They're operating on mutable implementations (as of jOOQ 3.x)
    • They're less composable and not easy to get right when dynamic SQL gets complex
    • They're less readable
    • They might have binary incompatible changes between minor releases

      • fields

        @NotNull
        @Support
        @NotNull LoaderListenerStep<R> fields​(Field<?>... fields)
        Specify the the fields to be loaded into the table in the correct order.

        The record column at index i is inserted into the table field at index i. If fields[i] == null or fields.length <= i, then the record column is skipped.

      • fields

        @NotNull
        @Support
        @NotNull LoaderListenerStep<R> fields​(Collection<? extends Field<?>> fields)
        Specify the the fields to be loaded into the table in the correct order.

        The record column at index i is inserted into the table field at index i. If new ArrayList(fields).get(i) == null or new ArrayList(fields).size() <= i, then the record column is skipped.

      • fieldsCorresponding

        @NotNull
        @Support
        @NotNull LoaderCSVOptionsStep<R> fieldsCorresponding()
        Indicate that all input fields which have a corresponding field in the target table (with the same name) should be loaded.
        Throws:
        LoaderConfigurationException - When the source data does not expose field names.
