How Can I Retrieve Column Names from a SQL Server Table Using INFORMATION_SCHEMA?

Accessing SQL Server Column Names via INFORMATION_SCHEMA

The INFORMATION_SCHEMA is a powerful tool within SQL Server for retrieving metadata, including crucial details like column names.

To obtain a list of column names for a specific table, use this SQL query:

<code class="language-sql">SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YourTableName';</code>

Replace 'YourTableName' with the actual name of your table (enclosed in single quotes). For example, to get the column names from a table named Products:

<code class="language-sql">SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Products';</code>

This refined query directly returns only the column names, making the output cleaner and more efficient.

Beyond column names, INFORMATION_SCHEMA offers access to a wealth of database object information. Key views frequently used include:

• CHECK_CONSTRAINTS
• COLUMN_DOMAIN_USAGE
• COLUMN_PRIVILEGES
• COLUMNS
• CONSTRAINT_COLUMN_USAGE
• CONSTRAINT_TABLE_USAGE
• DOMAIN_CONSTRAINTS
• DOMAINS
• KEY_COLUMN_USAGE
• PARAMETERS
• REFERENTIAL_CONSTRAINTS
• ROUTINES

• SCHEMATA
