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...
1. A new JSON object: To be sent recursively back into the parser: IF (@value IS NULL AND LEFT(@json, 1)='{') BEGIN; SELECT @recursion_counter=1, @offset=1; WHILE (@recursion_counter!=0 AND @offset<LEN(@json)) BEGIN; SET @offset=@offset+ PATINDEX('%[{}]%', SUBSTRING(@...

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) # ...

我们知道JSON.parse能将JSON字符串转变成JS对象,但在一些转换中可能出现Unexpected token ' in JSON at position 1的错误,这是因为被转换的值不符合JSON格式而造成的。 JSON官方明确规定,JSON数据的key与value必须使用双引号""包裹,否则在转换过程中会导致错误。
6.手写JSON.stringify、JSON.parse ? JSON.stringify JSON.stringify()方法将一个 JavaScript 对象或值转换为 JSON 字符串,如果指定了一个 replacer 函数,则可以选择性地替换值,或者指定的 replacer 是数组,则可选择性地仅包含数组指定的属性。 1 JSON.stringify(value[, replacer [, space]])...
Functions are not allowed in JSON. If you need to include a function, write it as a string. You can convert it back into a function later: Example Convert a string into a function: consttext ='{"name":"John", "age":"function () {return 30;}", "city":"New York"}'; ...
