![]() If (new.id is null) then new.id = next value for seq_withgeneratedid Id integer generated by default as identity primary key,įor Firebird 2.5 and earlier you will need to create a sequence and trigger: create table withgeneratedid(Ĭreate trigger withgeneratedid_bi before insert on withgeneratedid To be able to generate a primary key you can use the following solutions:įirebird 3 has an identity type column, so you don't need to create a sequence and trigger yourself: create table withgeneratedid( Using the Firebird ADO.net provider however, you need to execute statements one at a time, so a statement terminator is irrelevant. To address this, these tools have SET TERM to switch this terminator. By default these tools do that on a semi-colon ( ), but that doesn't work with PSQL (stored procedures, triggers), because PSQL code uses the semi-colon as well. This terminator is necessary to know when a statement is complete and can be sent to the server. ![]() ![]() Īre not recognized by the Visual Studio compiler.Īn important thing is that SET TERM is not part of the Firebird statement syntax, instead it is a client-side feature to set the statement terminator in query tools like ISQL. How do INSERT INTO Firebird, with autoincrement for the primary key?įor the table fields I have: fstPriority VARCHAR(30), fstInfo VARCHAR(100), fstDateCreated VARCHAR(30), fstDateModified VARCHAR(30), fiKeyID INTEGER PRIMARY KEYįor the INSERT INTO I have: FbConnection fbConn = new FbConnection(stOpenConn))įbTransaction fbTransaction = fbConn.BeginTransaction() įbCommand fbCmd = new FbCommand("INSERT INTO " + stTableName + "(" + stFieldNames + ") VALUES ( ) RETURNING fiKeyID ", fbConn, fbTransaction) īut am uncertain what should be used for theį "1st "2nd "3rd "4th value") Īlso, I see at creating an autoincrement column, but am uncertain how to do this in C#. ![]()
