开发过程中碰到一个关于mysql 全文检索的问题,控制台打印的SQL语句拿到数据库里执行,结果不对。后来发现原来是少了双引号。下面是网上找到的资料,我是看到这个才意识到自己的问题。
这是之前在数据库执行的SQL语句,检索结果上万条。
SELECT DISTINCT
c.Rm_Code,
c.Tsr_Code,
c.TradeName,
c.Location,
c.Tel_Number,
c.Url,
c.Nss_category1,
c.Nss_category2
FROM
CompanyMst c
INNER JOIN Tradename_keyword t ON t.rm_code = c.rm_code
WHERE
c.Show_flag = 0
AND MATCH(t.keyword_unicode)AGAINST(
'30d1 30bd 30ca ' IN BOOLEAN MODE
)
ORDER BY
LstEntDtm DESC,
Rm_Code ASC
这是之后改正后在数据库执行的SQL语句,检索结果11条。
SELECT DISTINCT
c.Rm_Code,
c.Tsr_Code,
c.TradeName,
c.Location,
c.Tel_Number,
c.Url,
c.Nss_category1,
c.Nss_category2
FROM
CompanyMst c
INNER JOIN Tradename_keyword t ON t.rm_code = c.rm_code
WHERE
c.Show_flag = 0
AND MATCH(t.keyword_unicode)AGAINST(
'"30d1 30bd 30ca "' IN BOOLEAN MODE
)
ORDER BY
LstEntDtm DESC,
Rm_Code ASC
