具体来说,我正在使用SQL Server Compact 4.0,如果这有所不同。我有3个表(注意,userTable,诗歌)。除了在此注释表中,用户和verse表没有相关性,因此我无法执行连接这两个表的单个子查询。
INSERT INTO [note]
([verse_id]
,[user_id]
,[text]
,[date_created]
,[date_modified])
VALUES
( (SELECT Id FROM verse
WHERE volume_lds_url = 'ot'
AND book_lds_url = 'gen'
AND chapter_number = 8
AND verse_number = 16)
, (SELECT Id FROM userTable
WHERE username = 'canichols2')
,'test message'
,GETDATE()
,GETDATE());
GO
据我所知,该声明应该有效。如果我对外键值进行硬编码,则外部语句可以正常工作,并且每个子查询都可以正常工作,并且每个子查询只返回一列和一行。
错误消息:There was an error parsing the query. [ Token line number = 8,Token line offset = 14,Token in error = SELECT ]
所以它不喜欢标量值子句中的子查询,但我无法弄清楚如何使用
INSERT INTO .... SELECT ....
声明与2个不同的表。
由于@Prasanna要求它,这里是定义
CREATE TABLE [userTable] (
[Id] int IDENTITY (1,1) NOT NULL
, [username] nvarchar(100) NOT NULL
, [email] nvarchar(100) NOT NULL
, [password] nvarchar(100) NULL
);
GO
ALTER TABLE [userTable] ADD CONSTRAINT [PK_user] PRIMARY KEY ([Id]);
GO
CREATE TABLE [note] (
[Id] int IDENTITY (1,1) NOT NULL
, [verse_id] int NULL
, [user_id] int NULL
, [text] nvarchar(4000) NOT NULL
, [date_created] datetime DEFAULT GETDATE() NOT NULL
, [date_modified] datetime NULL
);
GO
ALTER TABLE [note] ADD CONSTRAINT [PK_note] PRIMARY KEY ([Id]);
GO
CREATE TABLE [verse] (
[Id] int IDENTITY (1,1) NOT NULL
, [volume_id] int NULL
, [book_id] int NULL
, [chapter_id] int NULL
, [verse_id] int NULL
, [volume_title] nvarchar(100) NULL
, [book_title] nvarchar(100) NULL
, [volume_long_title] nvarchar(100) NULL
, [book_long_title] nvarchar(100) NULL
, [volume_subtitle] nvarchar(100) NULL
, [book_subtitle] nvarchar(100) NULL
, [volume_short_title] nvarchar(100) NULL
, [book_short_title] nvarchar(100) NULL
, [volume_lds_url] nvarchar(100) NULL
, [book_lds_url] nvarchar(100) NULL
, [chapter_number] int NULL
, [verse_number] int NULL
, [scripture_text] nvarchar(4000) NULL
);
GO
ALTER TABLE [verse] ADD CONSTRAINT [PK_scriptures] PRIMARY KEY ([Id]);
GO
我知道它不是第一种正常形式或任何东西,但这是给我的方式,我不想把它分成多个表格。
显示结果以及如何只有1行。
SELECT Id FROM WHERE volume_lds_url = 'ot'
AND book_lds_url = 'gen'
AND chapter_number = 8
AND verse_number = 16
ID 200
和第二个子查询
SELECT Id FROM userTable
WHERE username = 'canichols2'
ID 1
这个较小的兄弟似乎不支持子选择作为标量值,也不支持声明变量。在评论中查找详细信息
只要你可以肯定,子选择只返回一个标量值,你应该很容易将你的VALUES
转换为SELECT
。试试这个:
INSERT INTO [note]
([verse_id]
,[user_id]
,[text]
,[date_created]
,[date_modified])
SELECT
(SELECT Id FROM verse
WHERE volume_lds_url = 'ot'
AND book_lds_url = 'gen'
AND chapter_number = 8
AND verse_number = 16)
, (SELECT Id FROM userTable
WHERE username = 'canichols2')
,'test message'
,GETDATE()
,GETDATE();
没有使用Compact-SQL-Server的经验,但您可以尝试这样做:
DECLARE @id1 INT=(SELECT Id FROM verse
WHERE volume_lds_url = 'ot'
AND book_lds_url = 'gen'
AND chapter_number = 8
AND verse_number = 16);
DECLARE @id2 INT=(SELECT Id FROM userTable
WHERE username = 'canichols2');
INSERT INTO [note]
([verse_id]
,[user_id]
,[text]
,[date_created]
,[date_modified])
SELECT @id1
,@id2
,'test message'
,GETDATE()
,GETDATE();
