在mysql中将一个表的两个select语句相交

Question

IN CLAUSE

SELECT *  FROM build_req WHERE version = "8.2.0.1" IN (SELECT * FROM 
build_req where build_status = "Approval Pending");

错误

操作数应包含1列

UNION

SELECT *  FROM build_req WHERE version = "8.2.0.1" union SELECT * FROM 
build_req where build_status = "Approval Pending";

工会工作正常。我该如何克服这个错误？
