我导入了PostgreSQL数据库并且我一直收到此错误：
错误：运算符不存在：date＆gt; =整数LINE 1：... tut.id_pf AND clearlya_info_statut.data_sch_statut＆gt; = 2010-07 -... ^提示：否 运算符匹配给定的名称和参数类型。你可能需要 添加显式类型转换。
我的查询如下：
SELECT p_fiz.nr_certif，p_fiz.nume，p_fiz.prenume，localizari.id_jud，obviousa_info_statut.data_sch_statut，obviousa_info_statut.statut，rapoarte_anuale.data_depunere，rapoarte_anuale.angajamente，obviousa_asigurari.data_end，lista_statute.descriere，localizari.id_jud，p_fiz。 nume，p_fiz.prenume，p_fiz.nr_certif，p_fiz.id_pf，p_fiz.nume，p_fiz.prenume，p_fiz.codificare from p_fiz INNER JOIN localizari USING（id_loc）INNER JOIN obviousa_contacte USING（id_contact）LEFT JOIN lista_statute USING（id_statut_existenta）LEFT JOIN clearlya_info_statut ON p_fiz.id_pf = obviousa_info_statut.id_pf AND clearlya_info_statut.data_sch_statut＆gt; = 2010-07-12 LEFT JOIN rapoarte_anuale ON p_fiz.id_pf = rapoarte_anuale.id_pf AND rapoarte_anuale.an＆gt; 2010 LEFT JOIN obviousa_asigurari ON p_fiz.id_pf = obviousa_asigurari.id_pf AND obviousa_asigurari.data_start＆gt; = 2010-07-12 ORDER BY localizari.id_jud ASC，p_fiz.nume ASC，p_fiz.prenume ASC，p_fiz.nr_certif ASC;
据我了解，那是＆gt; =或＆gt;引起恐怖。
任何想法如何解决这个问题？
P.S。我在Fedora上运行PostgreSQL 8.4。

您需要引用日期。
evidenta_info_statut.data_sch_statut >= '2010-07-12'
evidenta_asigurari.data_start >= '2010-07-12'
没有引号，实际上它们被视为整数数学; 2010 - 7 - 12 = 1991

将日期换成引号
'2010-07-12'
