在这个例子中,regex_pattern是你想要匹配的正则表达式。例如,要匹配所有包含一个或多个数字的记录,你可以使用'\d+'作为正则表达式。 总结一下,pgsql提供了多种方式进行字符串包含匹配,包括基本的LIKE和ILIKE操作符,以及更高级的正则表达式匹配。选择哪种方法取决于你的具体需求和数据的特性。
使用函数jsonb_path_exists(可以指定JSON路径,如果是数组添加[*])的正则查询达到模糊查询的效果 -- like '%ggg%' SELECT * FROM "public"."tf_low_data_testUser" WHERE jsonb_path_exists("ports", '$[*].ports[*].nickname ?(@ like_regex "g")') -- 左模糊 like '%g' SELECT * FROM "publi...
LIKE 模式匹配总是覆盖整个字串。 要匹配在字串内部任何位置的序列,该模式必须以百分号开头和结尾。 要匹配文本的下划线或者百分号,而不是匹配其它字符, 在pattern 里相应的字符必须 前导逃逸字符。缺省的逃逸字符是反斜杠,但是你可以用 ESCAPE 子句指定一个。 要匹配逃逸字符本身,写两个逃逸字符。 请注意反斜杠...

We could tweak the regex I suppose, but that just seems like it's skirting around the actual problem. I could also get on board with Tom's idea of deprecating GSSAPI for Windows, assuming that SSPI can handle everything users might reasonably need (I really have no idea how likely that...
