Hello,

I am using Delphi 10.3.2, UniDAC 8.0.1, SQL Server 2012 Express 64Bit, targeting Win32 platform.

I have following script:

Code: Select all

CREATE VIEW [CRM_DayAlert] AS
SELECT     dbo.Customer.CustomerID, dbo.Customer.Username, dbo.CustomerContact.EntryDate, dbo.CustomerContact.EntryUser, 
                      dbo.CustomerContact.ContactName, dbo.CustomerContact.CustomerPosition, dbo.CustomerContact.Email, dbo.CustomerContact.Phone, 
                      dbo.CustomerContact.Extension, dbo.CustomerContact.MobilePhone, dbo.CustomerContact.Address, dbo.CustomerContact.Bithday, 
                      dbo.CustomerContact.Weddingday, dbo.CustomerContact.PartnerName, dbo.CustomerContact.PartnerBirthday, dbo.CustomerContact.ChildrenBirthDay, 
                      dbo.CustomerContact.VisitPeriod, dbo.CustomerContact.VisitDate, dbo.CustomerContact.PhoneCallPeriod, dbo.CustomerContact.PhoneCallDate, 
                      DATEADD(day, { fn MOD(CAST(dbo.CustomerContact.PhoneCallPeriod AS INT), DATEDIFF(day, dbo.CustomerContact.PhoneCallDate, GETDATE())) }, 
                      GETDATE()) AS PhoneCallPeriodDate, DATEADD(day, { fn MOD(CAST(dbo.CustomerContact.VisitPeriod AS INT), DATEDIFF(day, 
                      dbo.CustomerContact.VisitDate, GETDATE())) }, GETDATE()) AS VisitPeriodDate, CAST({ fn MOD(CAST(dbo.CustomerContact.VisitPeriod AS INT), 
                      DATEDIFF(day, dbo.CustomerContact.VisitDate, GETDATE())) } AS NVARCHAR) + N' gün sonra' AS VisitPeriodDateName, 
                      CAST({ fn MOD(CAST(dbo.CustomerContact.PhoneCallPeriod AS INT), DATEDIFF(day, dbo.CustomerContact.PhoneCallDate, GETDATE())) } AS NVARCHAR)
                       + N' gün sonra' AS PhoneCallPeriodDateName, dbo.Customer.VipCustomer, dbo.Customer.CustomerLock, dbo.CustomerPool.CustomerPool, 
                      dbo.CustomerCategory.CATEGORY, dbo.Customer.Customer
FROM         dbo.Customer INNER JOIN
                      dbo.CustomerContact ON dbo.Customer.CustomerID = dbo.CustomerContact.CustomerID INNER JOIN
                      dbo.CustomerPool ON dbo.Customer.CustomerPoolID = dbo.CustomerPool.CustomerPoolID INNER JOIN
                      dbo.CustomerCategory ON dbo.Customer.CustomerCategoryID = dbo.CustomerCategory.CAT_ID

That script executes fine in SQL Server Management studio, but fails when I run it using TUniQuery. Error I receive is:

Code: Select all

Empty macro or function name.

Same error raised when I try to copy paste that script in TUniQuery SQL editor.

Is there a way to run that script with TUniQuery?

Thanks & regards,
Ertan

If you assign False to the global variable EnableUniSQL in UniDAC, the driver won't look for macros in an SQL statement. You can find out more about macros in our docs:
https://www.devart.com/unidac/docs/unisql.htm

For example:

Code: Select all

uses
  Uni;

...

EnableUniSQL := False;

Is this an instant affect global variable? I mean, I have a code where I create database, tables, views. At that point I do not need macros. After all these, I will need macro support again.

Will it be enough to set that variable to True after I'm done all database creation stuff?

Yes, you can disable macros parsing for only SQL statements that contain ODBC function calls. For example:

Code: Select all

EnableUniSQL := False;
try
  ...
finally
  EnableUniSQL := True;
end;
