Hello,
How to look for a column lets say the column name has the word _commodity_ in it in a SQL DB.
My DB has 100's of tables, and I'm not sure which tables contain columns names stating or ending with the name commodity.
Thanks
SM

You can query the system tables:

SELECT * FROM sys.columns

WHERE name LIKE '%_commodity_%'

or

SELECT * FROM INFORMATION_SCHEMA.columns

WHERE column_name LIKE '%_commodity_%'

Get use to using the INFORMATION_SCHEMA version as it is a part of the SQL ANSI Standard whereas MS can modify the system tables with releases and patches INFORMATION_SCHEMA will always be supported.

This is fairly straightforward

selectobject_name(object_id) AS TableName

, name AS ColumnName

from sys.columns

where name like '%columnname string%'

select * from sys.tables

You should probably become more familiar with the information schema views available.

This

selectobject_name(object_id) AS TableName

from sys.columns

where object_name(object_id) like '%table name string%'

group by object_name(object_id)

order by 1

Not sure why you would use sys.columns to find table names. Why not use sys.tables? You would have to either use a group by or a distinct when looking at the columns or you have duplicates.
