我写了一个猪代码，我希望匹配一个包含多个字符串的列。例如
A = FOREACH A1 GENERATE
c1, c2, c3,
--i have substituted junk values--
case
when ( (
column_name matches '.*abc.*'
OR column_name matches '.*sdf.*'
OR column_name matches '.*bcd.*'
OR column_name MATCHES '.*def.*'
OR column_name MATCHES '.*efg.*'
OR column_name MATCHES '.*ggg.*'
OR column_name MATCHES '.*ghi.*'
OR column_name MATCHES '.*hij.*'
OR column_name MATCHES '.*ijk.*'
OR column_name MATCHES '.*jkl.*'
OR column_name MATCHES '.*klm.*'
OR column_name MATCHES '.*lmn.*'
or column_name matches '.*mno.*'
or column_name matches '.*mnb.*'
or column_name matches '.*opq.*'
or column_name matches '.*pqr.*'
or column_name matches '.*qrs.*'
or column_name matches '.*stuv.*'
or column_name matches '.*tuvw.*'
or column_name matches '.*wxy.*'
or column_name matches '.*tuvwx.*'
or column_name matches '.*xyz.*'
.

) then 1
else 0 as c4;
据观察，当 OR column_name MATCHES＆＃39; ---＆＃39; 语句的数量超过672时，pig脚本无法运行并出现错误：
