Begin by picking proc id from proc tbl, where proc id is in (p1); finish;The user anticipates entering several values separated by a comma or space, such as a1, b2, c3 in p1. All of the PROC IDs in proc tbl are capitalized. Therefore, all arguments to this stored procedure should be converted to lowercase before being sent to it.
Here's an example that uses the IN list constructor to supply multiple values for p1:
CREATE OR REPLACE PROCEDURE my_proc (p1 IN varchar2) IS BEGIN... END;
Then call it with a comma-separated list of values: my_proc(some_value),my_proc(another_value) ;
Compile the values into a single string separated by commas. Pass the string as a parameter into the SQL statement. Unpack the values and place them in a table with the customerid (select id from #temp).
Example: SELECT * FROM customers WHERE customerid IN (@param1, @param2);
Note: If any of the parameters are null then the WHERE clause will not be applied.
Convert a single column that contains several rows into a single row that contains multiple columns. SELECT @sql = 'SELECT Min CASE WHEN [Row Count] = '+ CAST [Row Count] AS CHAR(5) + 'THEN [Comments] END AS Comments' FROM [dbo]. DECLARE @sql AS NVARCHAR (MAX); SELECT @sql = 'SELECT Min CASE WHEN [Row Count] = '+ CAST Row SET @sql = @sql + N 'FROM [dbo]. INNER JOIN (SELECT * FROM [dbo].[Example]) AS T ON T.[ID] = S.[ID] + N' GROUP BY S.

INSERT INTO TABLE: Inserting One or More Rows
When merging data from various tables, it might be difficult to determine which SQL syntax to apply. The simplest fundamental technique to query many tables is using a simple SELECT statement. To mix results from many tables, use the FROM clause to call more than one table. You can reference columns from each of these tables in your result set by using the AS keyword followed by the column name.
For example, suppose you wanted to retrieve the names and email addresses for everyone in your database who was at least 18 years old. You could write this as a single query, or you could break it up into two separate queries by age group. Using two separate queries makes it easier to avoid duplicating information across tables and simplifies reporting later.
The correct syntax for this type of query is:
SELECT name, email FROM users WHERE users.age >= 18
There are several ways to write this query using only one SELECT statement. One way would be to create a new table called "merged" and copy all the user data into that table. Then you could use the merged table in future reports or applications. However, this is not the most efficient approach since it requires another table scan.
There is a distinction between a procedure and a function in Oracle. Is a sort of subprogram offered in the Oracle database's PL/SQL language that does not immediately return a value. Primary task A procedure, on the other hand, executes a task, whereas a function computes and returns a value. Values returned A method may or may not return a value, whereas a function always does. Conclusion In conclusion, a function is a piece of code that performs a task and returns a result while a procedure is a subroutine that can perform tasks associated with roles.
You can insert the rows into a single table or several tables using a single SQL statement.
