如何查找列数据的全部字符
如表:程序代码:
create cursor b1 (m1 c(3),m2 c(3)) insert into b1 values ("ab","bb") insert into b1 values ("a","b") insert into b1 values ("bb","a") insert into b1 values ("","bb") insert into b1 values ("bc","") insert into b1 values ("c","ab")
如何统计一列的全部字符,如M1列含有“abc” 字符,M2列有"ab"字符,用什么方法较好?
谢谢!
