Question: I want to write arrays into an InterBase table. Why doesn't the following code work?

pFIBQuery1->>SQL->Add("INSERT INTO T(A) VALUES(:A)");
pFIBQuery1->>pFIBQuery1->PrepareArrayFields();
pFIBQuery1->>ParamByName("A")->SetArrayValue( A );

Answer: You should use the PrepareArraySqlVar instead of PrepareArrayFields. PrepareArrayFields works with the array fields, and you do not have any array fields in your code. The PrepareArraySqlVar method works with parameters and informs the library which table and field your parameter refers to. So the correct code should be:

pFIBQuery1->>SQL->Add("INSERT INTO T(A) VALUES(:A)");
pFIBQuery1->>pFIBQuery1->PrepareArrayFields();
pFIBQuery1->>PrepareArraySqlVar(pFIBQuery1->ParamByName("A"),"T","A",False);
pFIBQuery1->>ParamByName("A")->SetArrayValue( A );

During a re-write of a very large software system we were having some difficulties utilizing a 3rd party grid that we had chosen. The dataset connectivity was very flaky due to the complex joins and updates we were using which caused the grids to behave very sketchy.  FIBPlus was the perfect solution for us. After implementing it everything became so much easier. The grid functionality stabilized, data retrieval was much faster, and we were pleasantly surprised by many of the unique features of your components. We were especially impressed with your pFIBUpdateObject components which allowed us to very easily update the multiple tables we were using in our joins.  Many thanks for your great components.
