Parameterized Statements

The following code example shows how to bind parameters to create parameterized statements.

Binding Parameters

Use the SQLBindParameter function to bind the specified parameter position to the specified variable. Note that the parameter order starts at 1.

Example

The following example executes a parameterized SELECT and iterates over the results. You can use SQLExecDirect to execute any parameterized statement.

  SQLHENV henv;
  SQLHDBC hdbc;
  SQLHSTMT hstmt;
  char sWorker_Reference_WID[30] = {0};
  SQLLEN cbsWorker_Reference_WID = 0;
  char param[30] = {0};
  strcpy(param, "00190000007ABC");
  SQLLEN cbParam = SQL_NTS;
  if (SQLAllocHandle(SQL_HANDLE_ENV, 0 ,&henv) == SQL_SUCCESS) {
    SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
    if (SQLAllocHandle(SQL_HANDLE_DBC, henv ,&hdbc) == SQL_SUCCESS) {
      if (SQLConnect(hdbc, "CData Workday Source", SQL_NTS, 0, 0, 0, 0) == SQL_SUCCESS) {
        if (SQLAllocHandle(SQL_HANDLE_STMT, hdbc ,&hstmt) == SQL_SUCCESS) {
          SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR, 100, 0, (SQLPOINTER)param, 30, &cbParam);
          if (SQLExecDirect(hstmt, "SELECT Worker_Reference_WID FROM [CData].[Human_Resources].Workers WHERE Legal_Name_Last_Name = ?", SQL_NTS) == SQL_SUCCESS) {
            while(SQLFetch(hstmt) == SQL_SUCCESS) {
              if (SQLGetData(hstmt, 1, SQL_C_CHAR, (SQLPOINTER)sWorker_Reference_WID, 255, &cbsWorker_Reference_WID) == SQL_SUCCESS) {
                printf("Worker_Reference_WID: %s\n", sWorker_Reference_WID);
              }
            }
          }
          SQLFreeHandle(SQL_HANDLE_STMT, hstmt);
        }
        SQLDisconnect(hdbc);
      }
      SQLFreeHandle(SQL_HANDLE_DBC, hdbc);
    }
    SQLFreeHandle(SQL_HANDLE_ENV, henv);
  }
