Values

analysis_error_to_string

</> 
pub fn analysis_error_to_string(error: AnalysisError) -> String

find_column

</> 
pub fn find_column(
  catalog: model.Catalog,
  table_name: String,
  column_name: String,
) -> option.Option(model.Column)

find_column_in_tables

</> 
pub fn find_column_in_tables(
  catalog: model.Catalog,
  table_names: List(String),
  column_name: String,
) -> Result(option.Option(#(String, model.Column)), List(String))

Search for a column across multiple tables, returning the column and the table name where it was found.

Returns Error(matching_table_names) when the column exists in more than one of the given tables (ambiguous reference).
