Functions ¶
func FindTablesWithAliases ¶
FindTablesWithAliases extracts table names and their corresponding aliases from a SQL query.
It analyzes the FROM clause, storing table aliases as keys in the returned map. If a table has no alias, its actual name is used as the key.
Parameters:
- query: The SQL query string to analyze.
Returns:
- A map where the key is the table alias (or the table name if no alias is used), and the value is the actual table name.
func ManipulateAST ¶
ManipulateAST modifies the SQL query by transforming column references to use the `json_extract` function in SQLite3, using the table name as the key.
SQLite3's `json_extract` function is used to extract values from JSON columns efficiently. It allows querying nested JSON fields directly within SQL queries.
Parameters:
- query: The original SQL query string to be modified.
- aliasToTable: A map that associates table aliases with their actual table names. If a table has no alias, its name is used as the alias.
Returns:
- A modified SQL query string with column references wrapped in `json_extract`.
