Struct DebugQuery 

#[non_exhaustive]
pub struct DebugQuery {
    pub description: String,
    pub sql_statement: String,
    /* private fields */
}

Specifies a SQL statement that is evaluated to return up to 10 scalar values that are used to debug rules. If the rule fails, the values can help diagnose the cause of the failure.

The SQL statement must use GoogleSQL syntax, and must not contain any semicolons.

You can use the data reference parameter ${data()} to reference the source table with all of its precondition filters applied. Examples of precondition filters include row filters, incremental data filters, and sampling. For more information, see Data reference parameter.

You can also name results with an explicit alias using [AS] alias. For more information, see BigQuery explicit aliases.

Example: SELECT MIN(col1) AS min_col1, MAX(col1) AS max_col1 FROM ${data()}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

description: String

Optional. Specifies the description of the debug query.

• The maximum length is 1,024 characters.

sql_statement: String

Required. Specifies the SQL statement to be executed.

Implementations

impl DebugQuery

pub fn new() -> Self

pub fn set_description<T: Into<String>>(self, v: T) -> Self

Sets the value of description.

Example

let x = DebugQuery::new().set_description("example");

pub fn set_sql_statement<T: Into<String>>(self, v: T) -> Self

Sets the value of sql_statement.

Example

let x = DebugQuery::new().set_sql_statement("example");

Trait Implementations

impl Clone for DebugQuery

fn clone(&self) -> DebugQuery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DebugQuery

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DebugQuery

fn default() -> DebugQuery

Returns the “default value” for a type.

impl Message for DebugQuery

fn typename() -> &'static str

The typename of this message.

impl PartialEq for DebugQuery

fn eq(&self, other: &DebugQuery) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
