  40. def resolveTable(options: JDBCOptions): StructType

    Takes a (schema, table) specification and returns the table's Catalyst schema.

    Takes a (schema, table) specification and returns the table's Catalyst schema.

    options

    - JDBC options that contains url, table and other information.

    returns

    A StructType giving the table's Catalyst schema.

    Exceptions thrown

    java.sql.SQLException if the table contains an unsupported type.

    Build and return JDBCRDD from the given information.

    Build and return JDBCRDD from the given information.

    sc

    - Your SparkContext.

    schema

    - The Catalyst schema of the underlying database table.

    requiredColumns

    - The names of the columns or aggregate columns to SELECT.

    predicates

    - The predicates to include in all WHERE clauses.

    parts

    - An array of JDBCPartitions specifying partition ids and per-partition WHERE clauses.

    options

    - JDBC options that contains url, table and other information.

    outputSchema

    - The schema of the columns or aggregate columns to SELECT.

    groupByColumns

    - The pushed down group by columns.

    sample

    - The pushed down tableSample.

    limit

    - The pushed down limit. If the value is 0, it means no limit or limit is not pushed down.

    sortOrders

    - The sort orders cooperates with limit to realize top N.

    returns

    An RDD representing "SELECT requiredColumns FROM fqTable".
