多字符串拆分javascript

Question

I'm working on an application that injects one query in a record field in a database . at the moment I need to take a string that contains a query and divide by commas

This is the string

APDoc.brn, APDoc.rbtn, APDoc.perd, APDoc.dtip, APDoc.U5, APDoc.Stt, APDoc.Ivcn, APDoc.InvcD, APDoc.Vndd AS Rut, Venr.ae AS Proveedor, APDoc.At, CASE APDoc.Dcype WHEN 'AD' THEN APDoc.OgDocmt * -1  WHEN 'PP' THEN APDoc.OrocAmt * -1 ELSE APDoc.OrocAmt END AS [Monto Fac], APDoc.POr, APDoc.Sb AS Entidad, APDoc.ProjeD, CASE APDoc.Dype WHEN 'AD' THEN APDoc.Dal * -1 WHEN 'PP' THEN APDoc.Dal * -1 ELSE APDoc.Dal END AS Saldo,  datediff(day, APDoc.Inate, GETDATE()) AS DIFERENCIA_DIAS 

basically had no problems by separating them with a split () and join ()

queryCortada      = queryCortada.split("AND").join(",").split("OR").join(",").split("(").join("").split(")").join("").split(",");

the problem is that the last field separates it into the following

datediff(day,
APDoc.Inate,
GETDATE()) AS DIFERENCIA_DIAS 

I need this field being only one, the idea is to have the following

APDoc.brn,
APDoc.rbtn,
APDoc.perd,
APDoc.dtip,
APDoc.U5,
APDoc.Stt,
APDoc.Ivcn,
APDoc.InvcD,
APDoc.Vndd AS Rut,
Venr.ae AS Proveedor,
APDoc.At,
CASE APDoc.Dcype WHEN 'AD' THEN APDoc.OgDocmt * -1  WHEN 'PP' THEN APDoc.OrocAmt * -1 ELSE APDoc.OrocAmt END AS [Monto Fac],
APDoc.POr, APDoc.Sb AS Entidad,
APDoc.ProjeD, CASE APDoc.Dype WHEN 'AD' THEN APDoc.Dal * -1 WHEN 'PP' THEN APDoc.Dal * -1 ELSE APDoc.Dal END AS Saldo,
datediff(day, APDoc.Inate, GETDATE()) AS DIFERENCIA_DIAS

The original text could contain more than one field as datediff( asdas,asdasd,asdasd)

Answer 1

To do this you either need to write a complex regex or parse the string through a lexical state-machine.

A simple split will always cause issues with future statements even if you think you covered your bases today.

Answer 2

你可以试试这个吗？

queryCortada.replace(/\((.*)\)+/g, "(temp**comma)").split("AND").join(",").split("OR").join(",").split("(").join("").split(")").join("").replace(/temp\*\*comma/g, ",").split(",");
