为什么 SQLite 命令在 Unity 中不起作用？

Question

如果此命令在 Sqlite 中为运行，则可以正常工作。但是，如果您从 Unity 尝试，则会发生错误。

'''

IDbCommand command = dbConnection.CreateCommand();
        command.CommandText = @"
                            UPDATE AnotherTable SET V1 = (SELECT Intelligence from Table1 
                                where AnotherTable.id in (
                            select AnotherTable.id from AnotherTable 
                                inner join Table1 on AnotherTable.id = Table1.Id
                                WHERE AnotherTable.V2 = 0 and AnotherTable.V1 = "") and 
                                Table1.Id = AnotherTable.Id) where id in(
                            select AnotherTable.id from AnotherTable 
                                inner join Table1 on AnotherTable.id = Table1.Id
                                WHERE AnotherTable.V2 = 0 and AnotherTable.V1 = "");
                            ";
command.ExecuteNonQuery();
command.Dispose();
base.SetCubicsGreenField();

错误文本：

'''

而不是空引号，使用：
