Sql select from exec sp

Executing a dynamically built string. The following example shows using sp _ executesql to execute a dynamically built string. The example stored procedure is used to insert data into a set of tables that are used to partition sales data for a year. We know sp _ execute , sp _executesql and exec are three different approaches to execute dynamic T- SQL queries or statements. There are two different ways to execute a stored procedure.

SQL Server - SELECT FROM stored procedure - Stack. The first and most common approach is for an application or user to call the procedure. After you have read this article, you will get to learn the basics of a dynamic SQL , how to build statements based on variable values, and how to execute constructed statements using sp _executesql and EXECUTE () from within a stored procedure. Changes in database context last only until the end of the EXECUTE statement. Dynamic SQL refers to SQL code generated based on user inputs.

For example, after the EXEC in this following statement is run, the database context is master. I have a stored procedure that generated a query string and then executes it with. Select Name, Age from tableA, so very simple. But how to get the result set back from the SP _EXECUTESQL (into a variable?) and then return it as result set in my stored procedure ? The EXEC command is used to execute a stored procedure , or a SQL string passed to it.

Like select sp _name_and_parameters from table_name_or_ sp _name_and_parameters or select Stack Exchange Network Stack Exchange network consists of 1QA communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Here are several reasons why Microsoft recommends using sp _executesql to run dynamic SQL : With EXECUTE all parameters much be converted from their native type to Unicode. By using sp _executesql, the optimizer recognizes the parameters within the dynamic SQL , making it easier for the optimizer to match plans.

To execute the stored procedure, click OK. Connect to the Database Engine. From the Standard bar, click New Query. This example shows how to execute a stored procedure that expects one parameter.

A dynamic SQL query is a query in string format. Stored Procedure spInventoryUpdate takes ItemCode and Quantity on input parameter. However I would reverse engineer that sp and make it run for multiple codes at the same time rather than at the time.

The next step is to create a view that provides the same result as the stored procedure you want to execute in queries. You can then use that view in a SELECT statement. EXEC command executes a stored procedure or string passed to it. Listing 1: sp _ConvProc2View. Please refer to EXEC SQL overview and examples for more details and examples on the EXEC command.

This feature allows us to modify the column names and column data types of the result sets returned by a stored procedure without actually modifying the stored procedure code. With this approach you are building the SQL statement on the fly and can pretty much do whatever you need to in order to construct the statement. For this example we want to get columns AddressI AddressLine1.

Then I want to store the result of this dynamic SQL statement, which would be contained in the parameterized column of the INSERTED table, to a variable.
