Hi Everyone,
I am using the app.config because I have to deal with different databases.
I absolutely cannot generate a table in a memory database.
If it's a real one it works properly.
my app.config:
<system.data>
<DbProviderFactories>
<add name="SQLite Data Provider" invariant="System.Data.SQLite"
description=".Net Framework Data Provider for SQLite"
type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
</DbProviderFactories>
</system.data>
<connectionStrings>
<!--<add name="Storage"
connectionString="Data Source = .\System\Storage_g.db;foreign keys=true;"
providerName="System.Data.SQLite" />-->
<add name="Storage"
connectionString="Data Source =:memory:; foreign keys=true;"
providerName="System.Data.SQLite" />
</connectionStrings>
with the Code:
DatabaseProviderFactory factory = new DatabaseProviderFactory();
this.database = factory.Create("Storage");
DbConnection cn = this.database.CreateConnection();
cn.Open();
DbCommand cmd = this.database.GetSqlStringCommand("CREATE TABLE Tab_1(Key
INTEGER, Value INTEGER)");
this.database.ExecuteNonQuery(cmd);
// this should generate error "Tab_1 already exists"
// but in memory it does not !!!!
this.database.ExecuteNonQuery(cmd);
Can anyone help me with this problem?
Thanks all;
