Function parseSnowflakeStatements

backend/plugin/parser/snowflake/snowflake.go:27–56

parseSnowflakeStatements is the ParseStatementsFunc for Snowflake. Returns []ParsedStatement with both text and AST populated. Each non-empty statement is parsed with the omni parser (the legacy ANTLR parser is gone). A parse failure on any statement fails the whole batch with a *base.SyntaxError —

(statement string)

// whole input, so positions inside one statement stay relative to it and are
// offset by the statement's start position afterwards.
func parseSnowflakeStatements(statement string) ([]base.ParsedStatement, error) {
	// First split to get Statement with text and positions
	stmts, err := SplitSQL(statement)
	if err != nil {
		return nil, err
	}

	var result []base.ParsedStatement
	for _, stmt := range stmts {
		ps := base.ParsedStatement{
			Statement: stmt,
		}
		if !stmt.Empty {
			node, err := parseOmniStatementNode(stmt.Text)
			if err != nil {
				return nil, convertOmniParseError(err, stmt)
			}
			ps.AST = &OmniAST{
				Node: node,
				Text: stmt.Text,
				// Keep the legacy ASTStartPosition shape: 1-based line of the
				// statement start, no column component.
				StartPosition: &storepb.Position{Line: int32(stmt.BaseLine()) + 1},
			}
		}
		result = append(result, ps)
	}

	return result, nil
}
