Firebird Info Class name: FirebirdStorage
Namespace: Chili.Opf3.Storages.Firebird
Current version: 1.0.5. How to use it This short example demonstrates how to use the storage in your code. | C# VB.NET | // Create the instance of the Firebird storage.
FirebirdStorage storage = new FirebirdStorage(
"User=user;Password=pass;Database=database.fdb;DataSource=localhost;");
// Set it as storage of the ObjectContext.
ObjectContext context = new ObjectContext(storage); ' Create the instance of the Firebird storage.
Dim storage As New FirebirdStorage( _
"User=user;Password=pass;Database=database.fdb;DataSource=localhost;")
' Set it as storage of the ObjectContext.
Dim context As New ObjectContext(storage) | How to make the storage work with autoincrement values This short example shows how to make the storage work with the AutoNumber (autoincrement) properties of the FieldAttribute. | C# VB.NET | // Specifies the generator in care of the autoincrement
// values. This generator must be defined in the database.
// {0} stands for the name of the entity.
// {1} stands for the name of the field.
storage.GeneratorFormat = "{0}_{1}_GEN"; ' Specifies the generator in care of the autoincrement
' values. This generator must be defined in the database.
' {0} stands for the name of the entity.
' {1} stands for the name of the field.
storage.GeneratorFormat = "{0}_{1}_GEN" | The format should be specified immediately after the instance of the storage class is created.
{0} stands for the name of the entity for which this generator is generated.
You may also add {1} which is then the name of the field for which the generator is created. When specifying the generator format as "{0}_{1}_GEN" for a persistent class mapped to the NEWS entity and the autoincrement field with name ID you need to generate the following generator in the database: NEWS_ID_GEN. The generator format needs only to be specified once. You need to create for each persistent object type with an AutoNumber a generator (fulfilling the specified format) in the database.
