Pervasive SQL 中没有详细信息的语法错误

Question

I am getting an error talking to a Pervasive SQL database, but without much details about what could be wrong. Do you have any advice about how I could debug where the problem is

Pervasive.Data.SqlClient.Lna.k: [LNA][PSQL][SQL Engine]Syntax Error.
   at Pervasive.Data.SqlClient.Lna.w.a(String , ad , l )
   at Pervasive.Data.SqlClient.PsqlCommand.a(Boolean , CommandBehavior , Boolean )
   at Pervasive.Data.SqlClient.PsqlCommand.ExecuteNonQuery()

Here is the code

using (PsqlCommand command = new PsqlCommand(sql, psqlConnection))
{
  command.Parameters.Clear();
  command.CommandText = sql;
  command.Parameters.AddWithValue("@KidDate", companyKIDDate);
  command.Parameters.AddWithValue("@KidTime", companyKIDTime);
  command.Parameters.AddWithValue("@KidMult", companyKIDMult);
  command.Parameters.AddWithValue("@KidComm", companyKIDComm);
  command.Parameters.AddWithValue("@DateGmt", companyKIDDate);
  command.Parameters.AddWithValue("@TimeGmt", companyKIDTime);
  command.Parameters.AddWithValue("@Seconds", companyKIDTime);  
  result = command.ExecuteNonQuery();
}

The query sql in the code is (keeping the weird formatting for exactitude).

INSERT INTO "FMUPDATE"
                        ("KID - date", "KID - time", "KID - user", "KID - mult", "KID - comm",
                        "Date GMT", "Time GMT",
                        "Flag",
                        "Pax Update",
                        "User ID",
                        "Count",
                        "Seconds",
                        "RockstarFlag")
                        VALUES(?, ?, 'RF01', ?, ?,
                        ?, ?,
                        1, 
                        1,
                        'RF01',
                        1,
                        ?,
                        1);

And here is the PsqlTrace of the error

The MKDE.TRA file is a Btrieve / Transactional engine level trace. The error you are seeing is a Relational engine error. Some Relational engine errors are the same as Transactional / Btrieve errors but most are not. You can turn on tracing within the Pervasive.Data.SqlClient interface using code like below:

PsqlTrace.TraceFile = "C:\\source\\debug\\MyTrace.txt";
PsqlTrace.RecreateTrace = 1;
PsqlTrace.EnableTrace = 1;

This will generate a file that has a format like:

Assembly Name:         Pervasive.Data.SqlClient, Version=4.1.0.0, Culture=neutral, PublicKeyToken=c84cd5c63851e072
Assembly File Version: 4.1.0.005024

    Error or Warning Received from Pervasive Server
    Number    = 0
    Message   = Pervasive.Data.SqlClient.Lna.w: [LNA][Pervasive][ODBC Engine Interface]Invalid column name: 'KID -NAME'.

Since this doesn't always happen, I would enable / disable the trace only around the calls that fail. Once you get the error, take a look at the trace and see if there's any more information. Posting here might get more eyes on it. If I had to guess, I would say that some value you are passing is invalid (00-00-0000 for a date, string for an integer, etc.).
