mysql stored procedure input parameter values - mysql

In MySQL stored procedures, is there any way to get input parameters and their values? I can get the parameter names from information_schema.parameters. But I also want to know the parameter values at run time.
The reason I want to get this is I have a large number of stored procedures. The first thing I want to do in every stored procedure is log input parameter values passed.

You can use SELECT IN_VAR_PARAM,This will print IN_VAR_PARAM input parameter on screen.If there is multiple input parameter then you can track them using same statement.
OR you can try with Log table.Just create simple LOG table and make entry of all input parameter one by one.
After complete execution of Procedure you can track all variable's value in LOG table.

How to access dataset parameter in query parameter while executing oracle stored procedure

I created data-set and trying to execute oracle stored procedure which has one input date/time parameter and three output parameters(One ref_cursor,two varchar).
Stored procedure accepts input parameter as Date/Time datatype and default is today's date.But when I am trying to execute the stored procedure,in the query parameters not bale to see the dataset parameter value created.
Please let me know how to pass dataset parameter to query parameter and execute the stored procedure.
Based on your screenshots, it looks like your using the TEXT query type and not the Stored Procedure.
In the Dataset Properties, you should select the Query Type of Stored Procedure. The parameters should work.

Sending results of a SELECT to stored procedure in MySQL

I have a stored procedure which takes one parameter. Ordinarily, it will be called as needed on a single id. Sometimes, though, it would be helpful to run it on every result from a SELECT. How can I take the results of a SELECT statement and run the stored procedure on each result?
This isn't directly possible, but...
As long as the stored procedure doesn't return a result-set, you can write a stored function that accepts the desired input and calls the procedure with the same value as an argument. If a stored function is used in a select query, it will generally be called for each row returned, unless it's referenced in the where clause, in which case, the optimizer may call it for more rows than you might expect, depending on the query plan.
Or you can move the logic into a stored function directly instead of using a procedure at all.

How to store returned result using mysql stored procedure

I am new to this community. May be this is a simple question but i have no idea how to store returned result of mysql query in an array which is of OUT parameter type using stored procedure.
Example: I am fetching some data from mysql database (select * from users) and it is returning an array. And I have to pass that array as an OUT parameter of stored procedure, how can i do that?
Can anyone suggest me good tutorial or reference for that?
Thanks in advance.
There isn't an ARRAY datatype in SQL. You can return other values via OUT params though (INT, VARCHAR, etc).
Your query will return a resultset. You can either deal with this inside the procedure using a cursor, put it into another (temporary) table or just exit.

SSRS call stored procedure using ReportItems! textbox. Maybe custom report code?

I need to call a stored procedure during my report to insert values into a table. These values are the result of fields from the dataset added. For example, I have a row of values, and the far right column is "ReportItems!TextBox1.Value + ReportItems!TextBox2.Value ..." This gives the correct total on the report. Now I need to call a procedure using this value as a parameter.
Using a stored procedure as a dataset, I am unable to reference the ReportItems! I am also unable to create additional report parameters (even internal or hidden) which could be a result of a dataset due to the reporting infrastructure we are using.
I know using custom report code, I can call a stored procedure and also reference the ReportItems, but I have been unable to find the correct syntax. I am not familiar with VB.net so please be specific. If i could get an example of how to call: Procedure TEST_INSERT(ReportItems!TextBox1.Value), I would be able to figure out how to implement it.
I am using an oracle backend as my data source.
Thanks
If I've understood you correctly, you want to do an database update using a value calculated with an expression in your report. My answer to this would be threefold.
First up: don't do it!.
Second: seriously, don't do it!! Reporting services is not meant or well suited for this kind of task, you most likely are looking at an XY-Problem.
Third, if you insist on doing it anyways, the easiest way I can think of to accomplish that is by using a seperate report to trigger the update, and pass the value you're after into a parameter for that report. In the main report, you set a click action on the cell with the total that calls the report, with the same value into the parameter.
A similar setup which may work as well, is to create a parameter based on the first dataset with that same "sum" expression you mention, and pass that down to another dataset.
However: don't do it! ;-)
I would set up a dataset in the report service that calls an update or insert function in oracle and returns a value/s. This way you can send in the total you need calculate and produce a result telling the user if the update was successful.
There is no special method for doing this just select or enter your procedure name and refresh the fields to update the parameter/s. See Oracle stored procedure in SSRS.
Also using this method you can run the stored procedure in oracle, update the table and display the results.

SSRS 2008 Data sets

I am new to SSRS;
What I would like to know is whether it is possible to have a dataset based on a dynamic stored procedure i.e the stored procedure requires an input parameter from the report and then using that can call any of a set of 'sub-stored procedures' that all return datasets with the same columns.
Basically, no.
SSRS at design time looks at the output of the stored procedure. If it is variable then it may not parse it. The same happens if you use temp tables. Also, the output would have to be the same for each proc
Now, switching stored proc is the same using that parameter to show or hide data regions, each based on a different dataset/proc. This is how I'd do it.
Or different sub-reports (which is a data region) or a whole new reports
If the "sub stored procedures" are already written, then your approach could work by having the stored proc called by the report create a temp table, then populate it based on the passed parameter, then return data from the temp table.
If the "sub stored procedures" are not already written, another option is just to use a CASE statement and have multiple SELECTs in the stored proc called by the report.
