Cursor might used for retrieving data row by row basis.its act like a looping statement (ie while or for loop). To use cursors in SQL procedures, you need to do the following: 1.Declare a cursor that defines a result set. 2.Open the cursor to establish the result set. 3.Fetch the data into local variables as needed from the cursor, one row at a time. 4.Close the cursor when done. for ex:
A cursor will only accept a select statement, so if the SQL really needs to be dynamic make the declare cursor part of the statement you are executing. For the below to work your server will have to be using global cursors.

93 I have a cursor containing several columns from the row it brings back that I would like to process at once. I notice most of the examples I've seeing on how to use cursors show them assigning a particular column from the cursor to a scalar value one at a time, then moving to the next row, e.g.

You select the actual columns in the query that defines the cursor, You then fetch those values into variables. There is an example in the documentation. Your FETCH is correct - the actual query that selects from the table is not. And a cursor that uses an undefined temp table is a bit unusual - but perhaps the code you posted is not complete.
My Current SQL Syntax is something like Declare CursorName CURSOR FOR Select Query Now the select query would contain an If-Else Condition. If @Parameter1 is NULL BEGIN Select-Query1 END ELSE
