TinyTds ::錯誤：過程預計參數

Question

鑑於以下紅寶石：

sql2 = 'SELECT (CASE WHEN freq = 0 THEN \'pass\' ELSE \'fail\' END) FROM ( 
SELECT COUNT(*) freq FROM Grant_Award WHERE Grant_Award.org_ticker IS NULL)x;' 
    pp ActiveRecord::Base.connection.select_all(sql2) 

    sql1 = "SELECT (CASE WHEN freq = 0 THEN 'pass' ELSE 'fail' END) FROM (SELECT COUNT(*) freq FROM Grant_Award WHERE Grant_Award.org_ticker IS NULL)x;" 
    pp ActiveRecord::Base.connection.select_all(sql1) 

    sql0 = File.readlines(File.join(BASE,'db','scripts','test','pass_or_fail.sql')) 
    sql = (sql0.map {|l| l.strip}).join(' ') 
    pp sql 
    pp ActiveRecord::Base.connection.select_all(sql) 

上面產生以下結果：

#<ActiveRecord::Result:0x38b0ce0 
@column_types={}, 
@columns=[""], 
@hash_rows=nil, 
@rows=[["pass"]]> 

#<ActiveRecord::Result:0x38b5ae0 
@column_types={}, 
@columns=[""], 
@hash_rows=nil, 
@rows=[["pass"]]> 

"SELECT (CASE WHEN freq = 0 THEN 'pass' ELSE 'fail' END) FROM (SELECT COUNT(*) freq FROM Grant_Award WHERE Grant_Award.org_ticker IS NULL)x;" 

C:/Ruby193/lib/ruby/gems/1.9.1/gems/activerecord-sqlserver-adapter-4.2.2/lib/active_record/connection_adapters/sqlserver/database_statements.rb:336:in `each': TinyTds::Error: Procedure expects parameter '@statement' of type 'ntext/nchar/nvarchar'.: EXEC sp_executesql 'SELECT (CASE WHEN freq = 0 THEN ''pass'' ELSE ''fail'' END) FROM (SELECT COUNT(*) freq FROM Grant_Award WHERE Grant_Award.org_ticker IS NULL)x;' (ActiveRecord::StatementInvalid) 

在執行SQL返回就好前兩個嘗試。第三個從文件讀入數組然後加入炸彈。我知道這一定與絃樂的處理有關。但我無法弄清楚這一點。

我在做什麼錯？爲什麼它（tinytds或activerecord？）認爲這是一個存儲過程？

我想要做的是在一個文件夾中有一大堆sql腳本，然後逐個執行它們。

詳細信息：紅寶石1.9.3，ActiveRecord的（4.2.0），和tiny_tds（0.6.2 86的mingw32）

Answer 1

我今天早上醒來，意識到它必須與磁盤上文件的字符集有關。下面是一個解決方案的工作[不改變查詢]：

ActiveRecord::Base.connection.select_all(sql0.join(" ").encode("UTF-8")) 

我強迫的字符集提交它的時候，現在一切執行罰款爲UTF-8。

證明：

#<ActiveRecord::Result:0x3bede68 
@column_types={}, 
@columns=[""], 
@hash_rows=nil, 
@rows=[["pass"]]> 

#<ActiveRecord::Result:0x3bf2c68 
@column_types={}, 
@columns=[""], 
@hash_rows=nil, 
@rows=[["pass"]]> 

"SELECT (CASE WHEN freq = 0 THEN 'pass' ELSE 'fail' END) FROM (SELECT COUNT(*) freq FROM Grant_Award WHERE Grant_Award.org_ticker IS NULL)x;" 

#<ActiveRecord::Result:0x3bf5410 
@column_types={}, 
@columns=[""], 
@hash_rows=nil, 
@rows=[["pass"]]> 

Answer 2

我想通過文件導入生成的語句應該是：

SELECT (CASE WHEN freq = 0 THEN 'pass' ELSE 'fail' END) FROM (SELECT COUNT(*) freq FROM Grant_Award WHERE Grant_Award.org_ticker IS NULL);" 

我認爲聲明結尾的x會導致錯誤，並懷疑它是否誤入其他行。
