这对我来说有点奇怪。
我有以下代码:
public static object[,] dbMultipleSingleQueries(string strDBPath, object[] oSQL)
{
//This is needed for attaching a DB.
object[,] objOut;
objOut = new Object[1, 1];
try
{
//Prepare DB connection string
strDBPath = "Data Source=" +
@strDBPath +
";Version=3";
//SQL Objs
SQLiteConnection dbConnection = new SQLiteConnection(strDBPath);
SQLiteCommand dbCommand = null;
SQLiteDataAdapter dbAdapter = null;
DataTable table = new DataTable();
//For looping
int j = 0;
//Conn str
dbConnection.Open();
dbCommand = new SQLiteCommand(dbConnection);
while (j < oSQL.Length)
{
try
{
dbCommand.CommandText = oSQL[j].ToString();
dbCommand.CommandType = System.Data.CommandType.Text;
if (j == (oSQL.Length - 1))
{
dbAdapter = new SQLiteDataAdapter(dbCommand);
dbAdapter.Fill(table);
objOut = table2Array(table);
}
else
{
dbCommand.ExecuteNonQuery();
objOut[0, 0] = "Success!";
}
}
catch (Exception e2)
{
System.Console.WriteLine(e2.StackTrace.ToString());
objOut[0, 0] = e2.StackTrace.ToString();
}
j++;
};
dbConnection.Close();
dbConnection = null;
}
catch (Exception e)
{
objOut[0, 0] = e.StackTrace.ToString();
}
return objOut;
}
如果我从这样的电子表格中提供我的论点,这将非常有效:
o = Application.Run("dbMultipleSingleQueries", "20130201.db", [test])
其中 [test] 是我的工作簿中的一个范围,其中包含有效的查询,看起来像这样:
attach database 'a.db' as d1
select * from d1.main
现在,如果我在 vba 中执行以下操作
Option Explicit
Sub Main()
Dim sql(1 To 2, 1 To 1)
sql(1, 1) = "attach database 'a.db' as d1"
sql(2, 1) = "select * from d1.main"
o = Application.Run("dbMultipleSingleQueries", "20130201.db", sql)
End Sub
这不起作用。我收到“类型不匹配”错误。任何输入为什么会是一个巨大的帮助,这让我发疯!
