匹配 IN 连接条件

Question

How to satisfy below condition on join without where condition?

SELECT *
FROM xyz
JOIN abc ON 
  MATCH(xyz.p) AGAINST(abc.h,abc.i,abc.j IN BOOLEAN MODE)

here xyz AND abc represent TABLES xyz.p, abc.h,abc.i,abc.j represent COLUMNS

Answer 1

It can be a little tricky to find the relevant documentation, but you cannot do what you want. In the section on full text restrictions :

• The argument to AGAINST() must be a string value that is constant during query evaluation. This rules out, for example, a table column because that can differ for each row.

I don't think MySQL offers an efficient way to do what you want. However, if you ask another question, it might be possible to solve your particular problem.
