当我尝试插入 PurchaseCredit 时出现此错误：
SQL 逻辑错误或缺少数据库外键不匹配 - “PurchaseCredit”引用“存款”
这是生成的 SQL 的一部分：
create table FinancialDeposit
(
Id integer primary key autoincrement,
Version BIGINT not null,
DatePayment date,
Total money,
Status INT,
)
create table Deposit
(
FinancialDepositId BIGINT not null unique,
AccountId BIGINT not null,
PersonName varchar(250) not null,
primary key (FinancialDepositId),
constraint FK737CDD9090887321 foreign key (AccountId) references Account,
constraint FinancialDepositFK foreign key (FinancialDepositId) references FinancialDeposit
)
create table PurchaseCredit
(
Id integer primary key autoincrement,
Version BIGINT not null,
PurchaseCode UNIQUEIDENTIFIER not null unique,
DepositId BIGINT,
Total money,
constraint FK737CDB4BFA0E8716 foreign key (DepositId) references Deposit
)
这是 C# 代码的一部分：
public class FinancialDepositMap : ClassMapping<FinancialDeposit>
{
public FinancialDepositMap()
{
Property(x => x.DatePayment, map => map.Column(a => a.SqlType("date")));
Property(x => x.Total);
Property(x => x.Status);
Property(x => x.DatePayment);
Property(x => x.Hash);
}
}
public class DepositMap : JoinedSubclassMapping<Deposit>
{
public DepositMap()
{
ManyToOne(x => x.AccountId, m => m.NotNullable(true));
Property(x => x.PersonName, m => m.NotNullable(true));
}
}
public class PurchaseCreditMap : ClassMapping<PurchaseCredit>
{
public PurchaseCreditMap()
{
Property(x => x.PurchaseCode, map =>
{
map.Unique(true);
map.NotNullable(true);
map.Update(false);
});
ManyToOne(x => x.Deposit);
Property(x => x.Total);
}
}
如何从“PurchaseCreditMap”映射列“存款”以获取此 SQL：
create table PurchaseCredit
(
...
constraint FK737CDB4BFA0E8716 foreign key (DepositId) references Deposit (FinancialDepositId)
)
