程序执行 SQL的时候 以上错误informix-SQLFetch_failed:_{error}_STATE=22002,_CODE=0,_MSG=[DataDirect][ODBC_Informix_dri
格式乱了，再写一下：
SQLSTATE Error Value Error Message
------------------------------------------------------------------------
22002 -11024 Indicator value required but not supplied
没有编辑功能，是使用SQLExtendedFetch会出现此错误的
SQLExtendedFetch extends the functionality of SQLFetch in the following ways:
•It returns row-set data (one or more rows), in the form of an array, for each bound column.
•It scrolls through the result set according to the setting of a scroll-type argument.
SQLExtendedFetch works with SQLSetStmtOption.
To fetch one row of data at a time in a forward direction, an application should call SQLFetch.
The following table describes the SQLSTATE and error values for SQLExtendedFetch.
