[英]EF Core with Oracle 11g. Problem with IDENTITY PK
The project is runnig with.Net Core 2.2, EF Core and SQL Server.该项目使用 .Net Core 2.2、EF Core 和 SQL 服务器运行。 Now, I need to use this same projetc with Oracle 11g.
现在,我需要将同一个项目与 Oracle 11g 一起使用。 I create a new Migration project with Oracle.ManagedDataAccess.Core.
我使用 Oracle.ManagedDataAccess.Core 创建了一个新的迁移项目。 The migration file generated is below:
生成的迁移文件如下:
migrationBuilder.CreateTable(
name: "AREAATUACAO",
schema: "SISDETEC",
columns: table => new
{
ID = table.Column<long>(nullable: false)
.Annotation("Oracle:ValueGenerationStrategy", OracleValueGenerationStrategy.IdentityColumn),
DATACADASTRO = table.Column<DateTime>(nullable: false),
DATAATUALIZACAO = table.Column<DateTime>(nullable: false),
NOME = table.Column<string>(nullable: true)
},
constraints: table =>
{
table.PrimaryKey("PK_AREAATUACAO", x => x.ID);
});
And the script generated is:生成的脚本是:
BEGIN
EXECUTE IMMEDIATE 'CREATE TABLE
"SISDETEC"."AREAATUACAO" (
"ID" NUMBER(19) GENERATED BY DEFAULT ON NULL AS IDENTITY NOT NULL,
"DATACADASTRO" TIMESTAMP(7) NOT NULL,
"DATAATUALIZACAO" TIMESTAMP(7) NOT NULL,
"NOME" NVARCHAR2(2000),
CONSTRAINT "PK_AREAATUACAO" PRIMARY KEY ("ID")
)';
END;
But, in the Oracle 11g do not exists the IDENTITY command.但是,在 Oracle 11g 中不存在 IDENTITY 命令。 The PKs must be generated with a trigger and a sequence.
必须使用触发器和序列生成 PK。
How can I config de EF Core to generate commands for Oracle version 11g?如何配置 EF Core 以生成 Oracle 版本 11g 的命令?

Customers using Oracle Database version 11.2 should set
UseOracleSQLCompatibility("11")
使用 Oracle 数据库版本 11.2 的客户应设置
UseOracleSQLCompatibility("11")
optionsBuilder.UseOracle("User Id=hr;Password=<password>;Data Source = inst1", b =>
b.UseOracleSQLCompatibility("11"));
