sql-server-2012

问题 I want to extract values from a JSON string in SQL. Started to write a function to do so but then I thought "surely someone else has already done this?". I was super excited when I saw there is a JSON_VALUE function in SQL Server now... but then sorely disappointed when I realized it wasn't added until 2016. :( So... I am in the middle of writing my own version of this function. I'm certain it will seem to work at first, and then I will get errors occasionally until I perfect it over time.

问题 I know there is a function called ISDATE to validate DATETIME columns, but it works only for the SMALLDATETIME and DATETIME types. Is there a similar way to validate the new data type DATETIME2 in SQL Server 2008 and 2012? 回答1: In SQL Server 2012, you can use TRY_CONVERT : SELECT TRY_CONVERT(DATETIME2, '2012-02-02 13:42:55.2323623'), TRY_CONVERT(DATETIME2, '2012-02-31 13:42:55.2323623'); Results: 2012-02-02 13:42:55.2323623 NULL Or TRY_PARSE : SELECT TRY_PARSE('2012-02-02 13:42:55.2323623' AS
