How can I get data from views in my mysql database using knex.js ?
I want to return this data in my nodejs route.get
SELECT c.id, nome_1
FROM pessoas_juridicas as pj
INNER JOIN pessoas as p
ON p.id = pj.pessoa_id
INNER JOIN clientes as c
ON c.pessoa_id = pj.pessoa_id
UNION
SELECT c.id, nome_1
FROM pessoas_fisicas as pf
INNER JOIN pessoas as p
ON p.id = pf.pessoa_id
INNER JOIN clientes as c
ON c.pessoa_id = pf.pessoa_id
WHERE p.id = 1
;
let sql = knex.from('live_calls' + ' as r')
.select('r.uuid', 'r.destination', 'r.current_status', 'r.src')
.where('r.uuid', '=', uuid );
sql.then((response) => {
console.log(response);
});
Here live_calls is a MySQL View.

First, I searched about the same problem but I didn't find an appropriate solution.
My problem is with the following code, it's returning wrong results:
SELECT FbID,FhID,
FbRef,
FbDate,
(D.AccName) AS DName,
FbQuan,
CONCAT(CategoryName,'-',ProductName) AS ProdName,
(C.AccName) AS CusName,
FhPurPrice,FbSalePrice,
(R.AccName) AS ResoName,
Curr1.CurrencyName,
Curr2.CurrencyName,
Plc1.PlaceName AS FhResoPlaceName,
Plc2.PlaceName AS FbCusPlaceName,
'linked' AS xLinkStatus,
1 AS xStatus
FROM tblfatora2 F2
INNER JOIN tblfatora1 F1 ON F1.FhRef = F2.FhRef
INNER JOIN tblproducts P ON P.ProductID = F1.FhProduct
INNER JOIN tblcategories CT ON CT.CategoryID = P.ProductCategory
INNER JOIN tblaccounts R ON R.AccID = F1.FhReso
INNER JOIN tblaccounts C ON C.AccID = F2.FbCus
INNER JOIN tblaccounts D ON D.AccID = F1.FhDriver
INNER JOIN tblcurrencies Curr1 ON C.AccCurrID = Curr1.CurrencyID
INNER JOIN tblcurrencies Curr2 ON R.AccCurrID = Curr2.CurrencyID
LEFT JOIN tblplaces Plc1 ON F1.FhResoPlace = Plc1.PlaceID
LEFT JOIN tblplaces Plc2 ON F2.FbCusPlace = Plc2.PlaceID
WHERE FIND_IN_SET(`FhID`, '18313,18314')
ORDER BY FbDate, FbID
the results that it gives me are: enter image description here
note: I use FIND_IN_SET here because I can't use (IN) where I use that SQL statement in a procedure inside vb.net code:
Public Sub MySql_GetLinked()
xDtAll = New DataTable()
Dim xPar(0) As MySqlParameter
xPar(0) = New MySqlParameter("#FhID", MySqlDbType.String) With {
.Value = LinkedFatora}
xClsMySql.GetData(xSqlLinked, xDtAll, xPar)
End Sub
So I fill the variable (LinkedFatora) by loop and I use the same SQL statement but I replace (WHERE FIND_IN_SET('FhID', '18313,18314')) with (WHERE FIND_IN_SET('FhID', #FhID)).
I looked for the error's reason but couldn't catch it.
I found the problem, it's changing (WHERE FIND_IN_SET(FhID, '18313,18314')) to (WHERE FIND_IN_SET(FbID, '18313,18314')):

am i did correct? it is giving correct result but it is taking too long to execute and get results. is there any better way to execute this query only with joins syntax and i don't have access to put index to the table
I have the following query and would like to convert it to using a left outer join instead of a not in to see if it would run faster that way. It's currently taking this query about 40 seconds to run on our database. I'm not familiar enough with using outer joins for this type of thing to convert it myself.

but it seems that my inner join objekt_artikel are not working. what should i change? because i didnt get a result. But there are results in the table.
Please am having difficulty in optimizing this query. What am trying to achieve is to join about 8 tables, of which only about 3 of the tables contains large data (1.5m records). This query returns expected records but is taking 1min to run which is bad.
I know it can be optimized to perform far better, pls i need assistance from you experts. I have index on the fields used for join already.
