a problem with SQL Server was encountered yesterday: a stored procedure was needed to process the data from several tables, and finally the problem was that I wanted to stitch a row of rows of one column of a table For example, there are two columns of data in the table:Ep_Classes ep_name AAA Enterprise 1AAA Enterprise 2AAA Enterprise 3BBB Enterprise 4BBB Enterprise 5I want to make this table the following format:Ep_Classes Ep_nameAAA Enterprise 1, Enterprise 2, Enterprise 3BBB Enterprise 4, Ent

functions or global variables in your code. There are some available modes to avoid this problem. The most basic point is to use the var keyword to initialize all variables.

But the conditions are a bit more, stitching up not only trouble, but also error-prone, So the idea of having the ID of the detail record in the form of a comma-delimited string (' 1 ', ' 2 ', ' 3 ') is followed by the group by, so i

As users learn how to program, they get points and rewards that appear in the user's information, whic
