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 );
