c# - Should I be using EF6 from a SQL CLR Function -

-

I have been hired to take some complex calculation code (C #) and research on going into the CLR function on SQL Server.

I have the problem that the calculation uses the data layer which uses EF6. Obviously I have to remove a small part of the existing code for the CLR function (SAR), but I still have to fulfill all the dependencies.

My question is how can I do this [which comes later :)] so should I will do this? Either way it is wrong to fill the entire EF in the database so that I am using it to calculate - it seems very bloated.

Opinion, suggestions, please consider?

Thanks

Unless pressing lot To keep the code-base in sync between the application layer and this SQLLLR function, I would say:

No, it does not seem like, if that is the case, it is useful to do this. You need some data points and using a simple SqlConnection for those simple string context connection = true; is very easy to use -process connection).

And, seeing that the performance is a concern (as it should be anyway, but still), this is the reason to go down to start this SQLCLR path, Manufacturer feels layers and layers of code that allow easy-to-use abstract layer, which is the unit framework.

Besides, why are you taking this function from within the function rather than passing it to the function? Are those values ​​passed which require additional look based on their special value?

  1. Scaler SQLLL function has been marked as IsDeterministic = true as . The input output in the SqlFunction attribute is cached and mapped so that they can be seen-up (in the context of additional rows in the same query) and the function is reused instead of being run again, and

  2. Scalar SQLCLR function is marked as IsDeterministic = true , and not marked DataAccess = DataAccessKind.Read SqlFunction attribute is acceptable in parallel schemes. If isDeterministic is not true or DataAccess (or even SystemDataAccess If marked as Read , they will function as regular T-SQL functions, so that they can prevent any query from receiving a parallel execution plan. Uses them.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
