name

public String name()

executeQuery

public QueryResult executeQuery(String statement,
 Consumer<QueryOptions> options)

Description copied from interface: Queryable

Executes a query statement using the specified options (query parameters, etc.), and buffers all result rows in memory.

If the results are not known to fit in memory, consider using the streaming version that takes a row action callback: Queryable.executeStreamingQuery(String, Consumer, Consumer).

Specified by:

executeQuery in interface Queryable

Parameters:

statement - The Columnar SQL++ statement to execute.

options - A callback for specifying custom query options.

Returns:

A query result consisting of metadata and a list of rows.

executeStreamingQuery

public QueryMetadata executeStreamingQuery(String statement,
 Consumer<Row> rowAction,
 Consumer<QueryOptions> options)

Description copied from interface: Queryable

Executes a query statement using the specified options, (query parameters, etc.), and passes result rows to the given rowAction callback, one by one as they arrive from the server.

The callback action is guaranteed to execute in the same thread (or virtual thread) that called this method. If the callback throws an exception, the query is cancelled and the exception is re-thrown by this method.

Specified by:

executeStreamingQuery in interface Queryable

Parameters:

statement - The Columnar SQL++ statement to execute.

options - A callback for specifying custom query options.

Returns:

Query metadata.

toString
