您可以使用带有显式模式的OPENJSON()来解析$.tagsJSON数组: DECLARE @json NVARCHAR(4000) SET @json = N'{ "id":"40476", "tags":[ { "id":"5f5883" }, { "id":"5fc8" } ], "type":"student", "external_id":"40614476" }' SELECT id FROM OPENJSON(@json, '$.tags') WITH (id varc...
dbo.fn_parse_json2xml(LEFT(@json, @offset)) AS varchar(max)); SET @json=SUBSTRING(@json, @offset+1, LEN(@json)); SET @nested=1; END 2a. Blank text (quoted) IF (@value IS NULL AND LEFT(@json, 2)='""') SELECT @value='', @json=LTRIM(SUBSTRING(@json, 3, LEN(@json))...
In this article, we will learn how to parse and query JSON in SQL Server with the help of the OPENJSON function. Firstly, we will briefly look at the data structure of the JSON and then we will learn details of the parsing and querying JSON data using the OPENJSON function. What is ...
接下来,你可以使用sqlparse.parse方法解析SQL查询语句,并使用sqlparse库中的相关方法提取where子句的JSON表示。下面是一个示例代码: 代码语言:txt 复制 import sqlparse query = "SELECT * FROM table WHERE column1 = 'value' AND column2 > 100" # 解析SQL查询语句 parsed = sqlparse.parse(query) # 提...

需要注意,当我们写出"3/1/2014"这个时间的时候,可以解释为2014年3月1日,也可以解释为2014年1月3日。这就存在二义性,dateparse默认采用mm/dd/yyyy这种格式,也就是2014年3月1日。我们也可以使用ParseStrict()函数让这种具有二义性的字符串解析失败: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 func ...
