Apache pig 为什么猪能'；不接受将整数转换为字符

我有一个猪的剧本：

CRE_22002 = LOAD '$input' USING  PigStorage(';') AS (GM_COMPTEUR:chararray,CIA_CD_CRV_CIA:chararray,CIA_DA_EM_CRV:chararray,CIA_CD_CTRL_BLCE:chararray,CIA_IDC_EXTR_RDJ:chararray,CIA_VLR_IDT_CRV_LOQ:chararray,CIA_VLR_REF_CRV:chararray,CIA_NO_SEQ_CRV:chararray,CIA_VLR_LG_ZON_RTG:chararray,CIA_HEU_CIA:chararray,CIA_TM_STP_CRE:chararray,CIA_CD_SI:chararray,CIA_VLR_1:chararray,CIA_DA_ARR_FIC:chararray,CIA_TY_ENR:chararray,CIA_CD_BTE:chararray,CIA_CD_PER:chararray,CIA_CD_EFS:chararray,CIA_CD_ETA_VAL_CRV:chararray,CIA_CD_EVE_CPR:chararray,CIA_CD_APLI_TDU:chararray,CIA_CD_STE_RTG:chararray,CIA_DA_TT_RTG:chararray,CIA_NO_ENR_RTG:chararray,CIA_DA_VAL_EVE:chararray,PSE_001:chararray,STR_002:chararray,STR_003:chararray,CPR_006_VLR:chararray,CPR_006_DCM:chararray,CPR_006_CD_DVS:chararray,CPR_008_VLR:chararray,CPR_008_DCM:chararray,CPR_008_CD_DVS:chararray,CPR_009_VLR:chararray,   CPR_009_DCM:chararray,CPR_009_CD_DVS:chararray,CPR_059_VLR:chararray,CPR_059_DCM:chararray,CPR_059_CD_DVS:chararray,CPR_060_VLR:chararray,CPR_060_DCM:chararray,CPR_060_CD_DVS:chararray,RUB_205:chararray,RUB_216:chararray,DAT_015_X:chararray,NB_005_VLR:chararray,NB_005_DCM:chararray,NB_007_VLR:chararray,NB_007_DCM:chararray,NB_012_VLR:chararray,NB_012_DCM:chararray,EUR_061_VLR:chararray,EUR_061_DCM:chararray,EUR_061_CD_DVS:chararray,EUR_062_VLR:chararray,EUR_062_DCM:chararray,EUR_062_CD_DVS:chararray);

我知道RUB_216列包含整数，但它是由espace给出的： 比如：

所以我决定把它演成chararray

运行pig脚本时：

CRE_22002 = LOAD '$input' USING  PigStorage(';') AS (GM_COMPTEUR:chararray,CIA_CD_CRV_CIA:chararray,CIA_DA_EM_CRV:chararray,CIA_CD_CTRL_BLCE:chararray,CIA_IDC_EXTR_RDJ:chararray,CIA_VLR_IDT_CRV_LOQ:chararray,CIA_VLR_REF_CRV:chararray,CIA_NO_SEQ_CRV:chararray,CIA_VLR_LG_ZON_RTG:chararray,CIA_HEU_CIA:chararray,CIA_TM_STP_CRE:chararray,CIA_CD_SI:chararray,CIA_VLR_1:chararray,CIA_DA_ARR_FIC:chararray,CIA_TY_ENR:chararray,CIA_CD_BTE:chararray,CIA_CD_PER:chararray,CIA_CD_EFS:chararray,CIA_CD_ETA_VAL_CRV:chararray,CIA_CD_EVE_CPR:chararray,CIA_CD_APLI_TDU:chararray,CIA_CD_STE_RTG:chararray,CIA_DA_TT_RTG:chararray,CIA_NO_ENR_RTG:chararray,CIA_DA_VAL_EVE:chararray,PSE_001:chararray,STR_002:chararray,STR_003:chararray,CPR_006_VLR:chararray,CPR_006_DCM:chararray,CPR_006_CD_DVS:chararray,CPR_008_VLR:chararray,CPR_008_DCM:chararray,CPR_008_CD_DVS:chararray,CPR_009_VLR:chararray,   CPR_009_DCM:chararray,CPR_009_CD_DVS:chararray,CPR_059_VLR:chararray,CPR_059_DCM:chararray,CPR_059_CD_DVS:chararray,CPR_060_VLR:chararray,CPR_060_DCM:chararray,CPR_060_CD_DVS:chararray,RUB_205:chararray,RUB_216:chararray,DAT_015_X:chararray,NB_005_VLR:chararray,NB_005_DCM:chararray,NB_007_VLR:chararray,NB_007_DCM:chararray,NB_012_VLR:chararray,NB_012_DCM:chararray,EUR_061_VLR:chararray,EUR_061_DCM:chararray,EUR_061_CD_DVS:chararray,EUR_062_VLR:chararray,EUR_062_DCM:chararray,EUR_062_CD_DVS:chararray);

有什么帮助吗？

为什么在将其加载到chararray中时需要将其强制转换为chararray？@VK_217，因为即使我将其加载到chararray中，它也不起作用。如果我将其强制转换为整数，则会显示错误消息无效格式。我添加TRIM是为了在列中不移动所需的空间。它显示了TRIM函数的问题。我真的找不到sol我已经尽力了possibility@VK_217，奇怪的是，消息错误是关于ToDate函数的，通常与DAT_015_X有关。但是，正如您所看到的，在消息错误中显示了列RUB_216的名称。您根本不需要第二条语句。加载后，在包含加载的关系上使用筛选器声明。@VK_217，好的，我会尝试并希望它能起作用！
