Detailed Description

The parser is responsible for parsing the query and converting it into a set of parsed statements. The parsed statements can then be converted into a plan and executed.

Member Function Documentation

ParseQuery()

void duckdb::Parser::ParseQuery

(

const string &

query

)

Attempts to parse a query into a series of SQL statements. Returns whether or not the parsing was successful. If the parsing was successful, the parsed statements will be stored in the statements variable.
