我在一个表中有4列(person\u id、account\u name、account\u id、account\u id)。对于每个人员id,我要查找在该人员id的“帐户id”列中不存在的所有帐户id。下面是一个示例表:
Person_id Account_Name Account_ID Account_IDs
--------------------------------------------------
123 Name3 ,000000ihi4MAQ, ,000000TF5MAHZ,000000TF5MAQQ,000000grVA6AM,000000ihi4MAQ,000016ILMhAO,
123 Name2 ,000016ILMhAO, ,000000TF5MAHZ,000000TF5MAQQ,000000grVA6AM,000000ihi4MAQ,000016ILMhAO,
123 Name1 ,000000grVA6AM, ,000000TF5MAHZ,000000TF5MAQQ,000000grVA6AM,000000ihi4MAQ,000016ILMhAO,
123 Name4 ,000000TF5MAQQ, ,000000TF5MAHZ,000000TF5MAQQ,000000grVA6AM,000000ihi4MAQ,000016ILMhAO,
123 Name5 ,000000TF5MAHZ, ,000000TF5MAHZ,000000TF5MAQQ,000000grVA6AM,000000ihi4MAQ,000016ILMhAO,
124 Name2 ,000016ILMhAO, ,000000frVA6AM,000016ILMhAO,
124 Name7 ,000024ILMhAO, ,000000frVA6AM,000016ILMhAO,
124 Name8 ,000000frVA7XZ, ,000000frVA6AM,000016ILMhAO,
124 Name5 ,000000TF5MAHZ, ,000000frVA6AM,000016ILMhAO,
124 Name6 ,000000frVA6AM, ,000000frVA6AM,000016ILMhAO,
125 Name11 ,000000frXC6A, ,000000frVA6BC,000024ILMhJZ,000000frXC6A,000024YTMhA,
125 Name9 ,000000frVA6BC, ,000000frVA6BC,000024ILMhJZ,000000frXC6A,000024YTMhA,
125 Name10 ,000024ILMhJZ, ,000000frVA6BC,000024ILMhJZ,000000frXC6A,000024YTMhA,
125 Name12 ,000024YTMhA, ,000000frVA6BC,000024ILMhJZ,000000frXC6A,000024YTMhA,
125 Name13 ,000024IXThJY, ,000000frVA6BC,000024ILMhJZ,000000frXC6A,000024YTMhA,
所以从这个样本来看,答案应该是:
Person_ID Account_ID Account_Name
-----------------------------------------
124 000000TF5MAHZ Name5
124 000024ILMhAO Name7
124 000000frVA7XZ Name8
125 000024IXThJY Name13
我不明白在划分表之后如何比较两列中的值。
提前谢谢你的帮助。
