从sequelize.query（）函数初始化存储过程/函数

Question

Here is my stored procedure

CREATE OR REPLACE FUNCTION GetAllEmployee()
RETURNS setof "Employees" AS
$BODY$
BEGIN
RETURN QUERY
select * from "Employees";
END;
$BODY$
LANGUAGE plpgsql;

And I am trying to call it from my route like this

    sequelize.sync().then(function() {

    app.get("/sp", (req, res) => {
        try {
            sequelize.query("GetAllEmployee()").then(function(data) {
                console.log(data);
            });

        } catch (error) {
            console.log(error);
        }

    });

});

But I keep getting this error message

Unhandled rejection SequelizeDatabaseError: syntax error at or near    "GetAllEmployee"

You need to add 'CALL' before the SP name.

Also you probably forgot to add an OUT parameter in your SP.

here's a demo code:

 sequelize.query('SET @outputData = null; CALL stored_procedure (:someInputData, @outputData); SELECT @outputData;', { replacements: { someInputData: 'Send Your Data Here', }, type: sequelize.QueryTypes.RAW, }) .spread(response => console.log(response, 'response')) .error((error) => { console.log(error, 'errored'); }); 

Note: add 'multipleStatements: true' to your sequelize config while creating instance, like so:

 const sequelize = new Sequelize(config.database.dbName, config.database.username, config.database.password, { host: config.database.host, dialect: config.database.dialect, logging: false, dialectOptions: { multipleStatements: true, }, });
