Module mysql

MySQL utilities for SQL purification.

Structs

MySqlExportStatementValues 🔒

PurifiedSourceExports 🔒

Statics

MYSQL_DATABASE_FAKE_NAME 🔒

The name of the fake database that we use for MySQL sources to fit our model of a 3-layer catalog. MySQL doesn’t have a concept of databases AND schemas, it treats both as the same thing.

Functions

external_reference_to_table 🔒

Convert an unresolved item name to a qualified table reference.

generate_create_subsource_statements

generate_source_export_statement_values 🔒

map_column_refs 🔒

Map a list of column references to a map of table references to column names.

normalize_column_refs 🔒

Normalize column references to a sorted, deduplicated options list of column names.

purify_source_exports 🔒

references_system_schemas 🔒

Checks if the requested external references contain any explicit references to system schemas, since these are otherwise default excluded when retrieving tables from MySQL.
