Execute SQL Query

Usage

db_sql_exec_query(
  statement,
  warehouse_id,
  catalog = NULL,
  schema = NULL,
  parameters = NULL,
  row_limit = NULL,
  byte_limit = NULL,
  disposition = c("INLINE", "EXTERNAL_LINKS"),
  format = c("JSON_ARRAY", "ARROW_STREAM", "CSV"),
  wait_timeout = "10s",
  on_wait_timeout = c("CONTINUE", "CANCEL"),
  host = db_host(),
  token = db_token(),
  perform_request = TRUE
)

Arguments

statement

String, the SQL statement to execute. The statement can optionally be parameterized, see parameters.

warehouse_id

String, ID of warehouse upon which to execute a statement.

catalog

String, sets default catalog for statement execution, similar to USE CATALOG in SQL.

schema

String, sets default schema for statement execution, similar to USE SCHEMA in SQL.

parameters

List of Named Lists, parameters to pass into a SQL statement containing parameter markers.

A parameter consists of a name, a value, and optionally a type. To represent a NULL value, the value field may be omitted or set to NULL explicitly.

See docs for more details.

row_limit

Integer, applies the given row limit to the statement's result set, but unlike the LIMIT clause in SQL, it also sets the truncated field in the response to indicate whether the result was trimmed due to the limit or not.

byte_limit

Integer, applies the given byte limit to the statement's result size. Byte counts are based on internal data representations and might not match the final size in the requested format. If the result was truncated due to the byte limit, then truncated in the response is set to true. When using EXTERNAL_LINKS disposition, a default byte_limit of 100 GiB is applied if byte_limit is not explicitly set.

disposition

One of "INLINE" (default) or "EXTERNAL_LINKS". See docs for details.

format

One of "JSON_ARRAY" (default), "ARROW_STREAM", or "CSV". See docs for details.

wait_timeout

String, default is "10s". The time in seconds the call will wait for the statement's result set as Ns, where N can be set to 0 or to a value between 5 and 50. When set to 0s, the statement will execute in asynchronous mode and the call will not wait for the execution to finish. In this case, the call returns directly with PENDING state and a statement ID which can be used for polling with db_sql_exec_status().

When set between 5 and 50 seconds, the call will behave synchronously up to this timeout and wait for the statement execution to finish. If the execution finishes within this time, the call returns immediately with a manifest and result data (or a FAILED state in case of an execution error).

If the statement takes longer to execute, on_wait_timeout determines what should happen after the timeout is reached.

on_wait_timeout

One of "CONTINUE" (default) or "CANCEL". When wait_timeout > 0s, the call will block up to the specified time. If the statement execution doesn't finish within this time, on_wait_timeout determines whether the execution should continue or be canceled.

When set to CONTINUE, the statement execution continues asynchronously and the call returns a statement ID which can be used for polling with db_sql_exec_status().

When set to CANCEL, the statement execution is canceled and the call returns with a CANCELED state.

host

Databricks workspace URL, defaults to calling db_host().

token

Databricks workspace token, defaults to calling db_token().

perform_request

If TRUE (default) the request is performed, if FALSE the httr2 request is returned without being performed.
