Examples

Works for the following code:

Procedure definition:

        CREATE OR REPLACE FUNCTION GetUserInfo(INOUT curName refcursor)
        LANGUAGE plpgsql
        AS $$
        BEGIN
            OPEN curName FOR
            SELECT user_id, username, email, age
            FROM users;
        END;
        $$;

Code:

import ballerina/sql;
import ballerina/io;
import ballerinax/postgresql; 
import ballerinax/postgresql.driver as _;

public function main() returns error? {
    postgresql:Client dbClient = check new ("localhost", "myuser", "mypassword", "mydatabase", 5432);

    transaction {
        sql:CursorInOutParameter curResults = new;

        sql:ProcedureCallResult result = check dbClient->call(`{CALL GetUserInfo(${curResults})}`);
        stream<record{}, sql:Error?> resultSet = curResults.get();

        record{}[] data = check from record{} assetAllocation in resultSet
           select assetAllocation;

        io:println(data);
        check result.close();
        check commit;

    }
}
