问题 Can i pass table variable as a PARAMETER To a Stored Procedure in MySql 回答1: If you want to pass a table into the stored procedure as parameter - then answer is no. Only scalar values can be passed. The table can be accessed by its name directly; if you want to use that table name to construct and run new query in procedure, then have a look at prepared statements. 回答2: yes TableA: MyId MyNumber 1 5 2 6 3 9 Select myNumber, MyStoredProcedure(MyNumber) from TableA where MyNumber > 5 来源： https:

问题 I read that sysname cannot be null, yet in the definition of the system procedure sp_grantdbaccess , I see the assignment of null to one of the procedure's arguments (if I read this right). How can this be? ALTER PROCEDURE [sys].[sp_grantdbaccess] @loginame sysname, @name_in_db sysname = NULL OUT 回答1: " SYSNAME cannot be NULL " is just not true. The linked question's answer is correct when it says that it's equivalent to NVARCHAR(128) NOT NULL as a default -- and then effectively only in

问题 Is there a way to use Command.Prepare, and Command.ExecuteNonQuery in VBA? The section entitled "Consider Using Command.Prepare" in the following article on ADO.NET describes objects and methods that are similar to ADODB properties and methods and I am wondering if there is an equivalent for VBA. ADODB has .Command, .Prepared, and .Parameters.Append, but I can't seem to put them together in a way that works similar to the sample code in the article. http://msdn.microsoft.com/en-us/library

问题 Note - as MaxU suggested below, the problem is specific to mysql.connector and does not occur if you use pymysql. Hope this saves someone else some headaches Using Python, Pandas, and mySQL and cannot get a stored procedure to return results at all, let alone into a data frame. I keep receiving errors about multiple queries, but the stored procedures I am running are extremely simple parameter driven queries. It doesn't matter what stored procedure I use, it is always the same result In fact,

问题 I am trying to save an old stored procedure into a string. When I use the following I do not get any line breaks. SELECT @OldProcedure = Object_definition(object_id) FROM sys.procedures WHERE name = @ProcedureName Any suggestions on how to get the stored procedure text with the line breaks? I was thinking of using sp_helptext Thanks Update I am copying and pasting the results from the results which will show me a single line. As for the script as I am storing the results in a db field. I am
