select语句本身没有问题,错误原因是:在构造游标时数据个数不一致。比如,一个表TA有3个域A,B,C。我们构造查询语句为:SELECT A FROM TA WHERE B='12' AND C='12'。但是在构造游标时,使用了EXEC SQL FETCH table_cursor INTO :A,:B,:C;,而不是EXEC SQL FETCH table_cursor INTO :A;。这样变量数目就...

Don't use a variable in a SELECT statement to concatenate values (that is, to compute aggregate values). Unexpected query results might occur because all expressions in the SELECT list (including assignments) aren't necessarily run exactly once for each output row. For more information, see KB...
