SQLExecute總是返回「[Microsoft] [SQL Server Native Client 10.0]字符串數據，右截斷」參數大於8k大小

當我執行SQLExecute函數時，它始終返回「Microsoft [SQL Server Native Client 10.0]字符串數據，正確的截斷「當我的參數超過8k字節。我將粘貼下面的代碼。我在做什麼：在SQL Server 2008 R2中通過ODBC驅動程序（Visual C++ 2008）通過存儲過程將XML文件存儲在聲明爲varbinary（max）的列中。 SP從varchar轉換爲varbinary調用SET @XML_FILE_BIN = CONVERT(VARBINARY(MAX), @XML_FILE) 如果我嘗試在SQL Server Management Studio中粘貼整個XML，它會正常工作。我認爲SQLBindParameter中的綁定有問題。該代碼：SQLExecute總是返回「[Microsoft] [SQL Server Native Client 10.0]字符串數據，右截斷」參數大於8k大小

char* cXmlBuf; it contains my buffer 
retcode = SQLBindParameter(
    hstmt,    //StatementHandle 
    1,     //ParameterNumber 
    SQL_PARAM_INPUT, //InputOutputType 
    SQL_C_CHAR,   //ValueType 
    SQL_CHAR,   //ParameterType 
    SQL_DESC_LENGTH, //ColumnSize 
    0,     //DecimalDigits 
    cXmlBuf,   //ParameterValuePtr 
    bufLenght,   //BufferLength 
    &cbXml    //StrLen_or_IndPtr 
); 

if (retcode != SQL_SUCCESS && retcode != SQL_SUCCESS_WITH_INFO) 
    return; 

SWORD id = 0; 
SQLINTEGER cbId = 0; 
retcode = SQLBindParameter(hstmt, 2, SQL_PARAM_OUTPUT, SQL_C_SSHORT, SQL_INTEGER, 0, 0, &id, 0, &cbId); 

if (retcode != SQL_SUCCESS && retcode != SQL_SUCCESS_WITH_INFO) 
    return; 

retcode = SQLPrepare(hstmt, (SQLCHAR*)"{CALL MY_STORE_PROC(?, ?)}", SQL_NTS); 

if (retcode != SQL_SUCCESS && retcode != SQL_SUCCESS_WITH_INFO) 
    return; 

retcode = SQLFreeStmt(hstmt, SQL_CLOSE); // Clear any cursor state 
retcode = SQLExecute(hstmt); 
//in this part retcode is -1 and "[Microsoft][SQL Server Native Client  
//10.0]String data, right truncation" is returned if my XML buffer 
//has more than 8k

找到了！我宣佈SQLINTEGER cbXml = SQL_NTS;而不是SQLLEN cbXml = 0; 謝謝。
