如何在数据库 Teradata 中查找具有特定列名的所有表？

Question

I have 2-3 different column names that I want to look up in the entire DB and list out all tables which have those columns. Any easy query?

I have seen solution for MySQL , which won't work here because TD as far as I know don't have schemes, but instead I found this .

And tried this code:

SELECT TableName
FROM DBC.COLUMNS
WHERE DatabaseName = 'DB_NAME' and
ColumnName in ('col1', 'col2')

But surely subquery must be used to get TableName, because DBC.COLUMNS doesn't have that field. Any further ideas?

Answer 1

You are looking for this:

SELECT tablename
FROM dbc.columnsV
WHERE ColumnName in ('col1', 'col2')

Answer 2

This query works with me :

SELECT  DatabaseName,
        TableName,
        CreateTimeStamp,
        LastAlterTimeStamp
FROM    DBC.TablesV
WHERE   TableKind = 'T'
and     DatabaseName = 'YOUR_SCHEMA'
ORDER BY    TableName;
