MySQL的DELETE查询错误

它扔像

错误
'操作数应包含一列'

delete from l0_clarabridge_s.incr_sentence_class_xref where incr_sentence_class_xref.document_id NOT IN (
select * 
from l0_clarabridge_s.incr_sentence_class_xref 
join l0_clarabridge_s.incr_document 
on incr_sentence_class_xref.document_id = incr_document.document_id);

使用'选择id_column ....'，而不是'SELECT * .....'。 – Wanderer

[操作数应该包含1列的可能的重复 - MySQL不在]（http://stackoverflow.com/questions/6318208/operand-should-contain-1-column-mysql-not-in） – Wanderer

即使在添加document_id之后，从l0_clarabridge_s.incr_sentence_class_xref其中DOCUMENT_ID NOT IN（选择x.document_id 从l0_clarabridge_s.incr_sentence_class_xref X 上x.document_id = d.document_id加入l0_clarabridge_s.incr_document d ）选择*; –

添加DOCUMENT_ID您的选择：

delete from l0_clarabridge_s.incr_sentence_class_xref where incr_sentence_class_xref.document_id NOT IN (
select incr_sentence_class_xref.document_id 
from l0_clarabridge_s.incr_sentence_class_xref 
join l0_clarabridge_s.incr_document 
on incr_sentence_class_xref.document_id = incr_document.document_id);

你是你WHERE语句比较两列，而不是一个，请尝试以下操作：

DELETE FROM l0_clarabridge_s.incr_sentence_class_xref WHERE incr_sentence_class_xref.document_id NOT IN (
SELECT [insert your ID column name here] 
FROM l0_clarabridge_s.incr_sentence_class_xref 
JOIN l0_clarabridge_s.incr_document 
ON incr_sentence_class_xref.document_id = incr_document.document_id);
