The log information of the package does not contain the logs when the package is successfully executed. Sometimes we only care about whether the package is successfully executed or fails. Although the SQL Server SSIS log provider does not record successful packet execution information by default, you can modify the stored procedure it calls to record a successful message. 1. Right-click the blank space in the control flow of the package and choose j

UDFs are similar to stored procedures, where a user-defined function is an ordered set of T-SQL statements that are pre-optimized and compiled, and can be used as a unit to test calls. The main difference between UDFs and stored procedures is the way the results are returned, and in order to support more return values, UDFs are more restrictive than stored procedures.UDF basic syntax: CREATE FUNCTION RETURNS As Begin/* code */ENDThe simplest thing to

The original intention is to record some of their own idea, but also want to be able to help some coincidence encounter such a problem, the need for the beginning is because, to count the last n weeks of sales data.
