select COLUMN_NAME
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='Submenu';
The above query gave all column names in Submenu table but I want only three column names of Submenu table.
Is there any way to get column names?
I assumed this is SQL Server, so the below queries might not work on other RDBMS's).
If your question is how to find only the column names you need (presuming you know in advance which ones those are), you would have to do something like this:
SELECT
COLUMN_NAME
FROM
INFORMATION_SCHEMA.COLUMNS
WHERE
TABLE_NAME='Submenu'
AND COLUMN_NAME IN ('Column1', 'Column2', 'Column3')
At this moment, you basically are requesting a list of any column within your table, without any restrictions whatsoever.
Alternatively, if you're looking only for the first three column names, this would work:
SELECT TOP 3
COLUMN_NAME
FROM
INFORMATION_SCHEMA.COLUMNS
WHERE
TABLE_NAME='Submenu'
ORDER BY
ORDERINAL_POSITION
In the latter case, you will have to determine how you want to sort the column names though (either by using something like ORDER BY COLUMN_NAME, in case you want them listed alphabetically, or ORDER BY ORDERINAL_POSITION in case you're trying to get them in the order they appear in the table).
If this is not what you meant, please elaborate on what you are trying to achieve.
