通過 OLE DB 串連 MSSQL Server時出現亂碼的解決方案

server|解決 當使用OLE DB方式與MS SQL Server串連時,如果資料庫的字碼頁與本地的不同,當進行查詢時字元的傳回值就會變成 ? 或是亂碼, 微軟的網站上說這是一個BUG, 並且描述如下:
When you try to retrieve character data from a column with different collation than the client code page in Microsoft SQL OLE DB Provider (SQLOLEDB), you may receive question marks (??) instead of correct data when all the following conditions are true:
•A connection is made against a Microsoft SQL Server 2000 database.
•SSPROP_INIT_AUTOTRANSLATE is set to TRUE. SSPROP_INIT_AUTOTRANSLATE is part of the provider-specific DBPROPSET_SQLSERVERDBINIT property set.
•A column is bound to an OLEDB DBTYPE_WCHAR data type in the bindings structure.

我的解決方案是關掉 自動字元轉換. 例子如下:(PowerBuilder 中)
SQLCA.DBMS = 'OLE DB'
SQLCA.LogID = 'sa'
SQLCA.LogPass = ''
SQLCA.DBParm = “PROVIDER='SQLOLEDB', DataSource='my-server', CommitOnDisconnect='no', ProviderString='Database=mydb, AutoTranslate=no'”
