ODBC Driver for Sage 200

Build 20.0.7587

Querying Data

After Connecting, you can allocate a statement handle and execute the statement.

SELECT Procedure

Use SQLExecDirect to execute the statement and SQLFetch to fetch the records. You can use SQLBindCol to bind variables to columns in the result set. The numbering of the result set columns starts at 1.

SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv); 
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc); 
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"Dsn=CData Sage200 Source", SQL_NTS, 0, 0, 0, 0);
SQLAllocHandle(SQL_HANDLE_STMT, hdbc, &hstmt);
SQLExecDirect(hstmt, (SQLCHAR*)"SELECT Code FROM Banks WHERE Description = 'Bob'", SQL_NTS);  
SQLCHAR sCode[20] = {0};
SQLLEN cbCode = 0;
SQLBindCol(hstmt, 1, SQL_C_CHAR, sCode, 20, &cbCode);
SQLRETURN retcode = SQLFetch(hstmt);
if (retcode == SQL_SUCCESS || retcode == SQL_SUCCESS_WITH_INFO) {
 ...
}

Iterating over the Results

You can use SQLGetData to get values while iterating through a cursor. To iterate over the results, use SQLFetch to fetch rows and SQLGetData to retrieve the column values.

  SQLHENV henv;
  SQLHDBC hdbc;
  SQLHSTMT hstmt;
  char sId[255] = {0};
  SQLLEN cbId = 0;
  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 Sage200 Source", SQL_NTS, 0, 0, 0, 0) == SQL_SUCCESS) {
        if (SQLAllocHandle(SQL_HANDLE_STMT, hdbc ,&hstmt) == SQL_SUCCESS) {
          if (SQLExecDirect(hstmt, "SELECT Id FROM Banks WHERE Description = 'Bob'", SQL_NTS) == SQL_SUCCESS) {
            while(SQLFetch(hstmt) == SQL_SUCCESS) {
              if (SQLGetData(hstmt, 1, SQL_C_CHAR, (SQLPOINTER)sId, 255, &cbId) == SQL_SUCCESS) {
                printf("Id: %s\n", sId);
              }
            }
          }
          SQLFreeHandle(SQL_HANDLE_STMT, hstmt);
        }
        SQLDisconnect(hdbc);
      }
      SQLFreeHandle(SQL_HANDLE_DBC, hdbc);
    }
    SQLFreeHandle(SQL_HANDLE_ENV, henv);
  }
