Implementations§

source§

impl SourceCatalog

source

pub fn create_sql(&self) -> String

Returns the SQL definition when the source was created.

source

pub fn create_sql_ast(&self) -> Result<Statement, RwError>

Returns the parsed SQL definition when the source was created.

Returns error if it’s invalid.

source

pub fn to_prost(&self) -> PbSource

source

pub fn version(&self) -> SourceVersionId

Get a reference to the source catalog’s version.

source

pub fn connector_name(&self) -> String

source§

impl SourceCatalog

source

pub fn create_sql_purified(&self) -> String

Returns the SQL definition when the source was created, purified with best effort.

source

pub fn create_sql_ast_purified(&self) -> Result<Statement, RwError>

Returns the parsed SQL definition when the source was created, purified with best effort.

Returns error if it’s invalid.

source

pub fn fill_purified_create_sql(&mut self)

Fills the definition field with the purified SQL definition.

There’s no need to call this method for correctness because we automatically purify the SQL definition at the time of querying. However, this helps to maintain more accurate definition field in the catalog when directly inspected for debugging purposes.
