How to find column names for all tables in all databases in SQL Server

Question

I want to find all column names in all tables in all databases. Is there a query that can do that for me? The database is Microsoft SQL Server 2000.

Answer 1

I just realized that the following query would give you all column names from the table in your database (SQL SERVER 2017)

SELECT DISTINCT NAME FROM SYSCOLUMNS 
ORDER BY Name 

OR SIMPLY

SELECT Name FROM SYSCOLUMNS

If you do not care about duplicated names.

Another option is SELECT Column names from INFORMATION_SCHEMA

SELECT DISTINCT column_name  FROM INFORMATION_SCHEMA.COLUMNS
ORDER BY column_name

It is usually more interesting to have the TableName as well as the ColumnName ant the query below does just that.

SELECT 
   Object_Name(Id) As TableName,
   Name As ColumnName
FROM SysColumns

And the results would look like

  TableName    ColumnName
0    Table1    column11
1    Table1    Column12
2    Table2    Column21
3    Table2    Column22
4    Table3    Column23
