我在 SQL Server 中有一个查询
SELECT
k12_dms_contacts_master.prefix_id AS prefix,
k12_dms_contacts_master.first_name,
k12_dms_contacts_master.last_name,
k12_dms_contacts_master.email,
k12_dms_institution_master.inst_name,
k12_dms_institution_master.address,
k12_dms_cities.name AS city_name,
k12_dms_zip_codes.zip_code,
k12_dms_institution_master.type_id,
k12_dms_contacts_institution_jobtitles.glevel_id,
k12_dms_districts.name AS district_name,
k12_dms_counties.name AS county_name,
k12_dms_institution_master.state_id,
k12_dms_institution_master.phone,
k12_dms_contacts_institution_jobtitles.job_title_id
FROM
k12_dms_institution_master
INNER JOIN k12_dms_contacts_institution_jobtitles ON k12_dms_contacts_institution_jobtitles.inst_id = k12_dms_institution_master.id
INNER JOIN k12_dms_contacts_master ON k12_dms_contacts_institution_jobtitles.contact_id = k12_dms_contacts_master.id
INNER JOIN k12_dms_cities ON k12_dms_cities.id = k12_dms_institution_master.city_id
INNER JOIN k12_dms_districts ON k12_dms_districts.id = k12_dms_institution_master.district_id
INNER JOIN k12_dms_counties ON k12_dms_counties.id = k12_dms_institution_master.county_id
INNER JOIN k12_dms_zip_codes ON k12_dms_zip_codes.id = k12_dms_institution_master.zip_code_id
WHERE
k12_dms_zip_codes.zip_code IN ('92678', '92679', '92688', '92690', '92691', '92692', '92693', '92694', '92877',
'92879', '92881', '92883')
ORDER BY
k12_dms_institution_master.state_id,
k12_dms_institution_master.inst_name ASC
现在我想GROUP BY
对电子邮件地址和机构名称执行,但我收到此错误:
列 'k12_dms_contacts_master.prefix_id' 在选择列表中无效,因为它不包含在聚合函数或 GROUP BY 子句中。
任何帮助都将是非常可观的。
