![]() 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#.
