SQL Server : How to fetch data from dynamic multiple tables?

问题

Using SQL SERVER.

The database contains data from different years, somehow I want to fetch all the data (all the years) and show to the user, for example, database contains table:

table
--------
records_2000_01
records_2000_02
records_2000_03
...

now through select TABLE_NAME into @tableName from information_schema.tables where table_name like 'records_%'

I can fetch all the table name, how to write a SQL (or perhaps procedure) to fetch all data from these tables? make all record into one table?

thx.

回答1:

Create procedure in this Below steps you need to follow.

• Create table Common_Table with same one structure which all your table like records_2000_02 and others.
• Use loop or cursor for all records you get from information_schema which match your table name
• Create dynamic sql like ' Insert into your Common_Table select * from ' + Table_name that you get from Information_schema.
  • Then you get all your data in one table Common_Table
