How to find tables and columns in SQL Server

Searching for tables and columns In SQL Server can be a daunting task, especially when working with large databases. In this article, we will cover various methods and techniques that can help you find tables and columns in SQL Server efficiently. This guide will show you how to use different tools and commands to locate the information you need.

Using the Information Schema

One of the easiest ways to find tables and columns in SQL Server is by querying the information_schema. The information_schema is a standardized set of views provided by SQL Server that contains metadata about your database objects, such as tables, columns, and constraints.

Finding Tables

To find tables in your database, you can use the following query:

SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND TABLE_CATALOG = 'YourDatabaseName';

Replace ‘YourDatabaseName’ with the name of the database you want to search.

Finding Columns

To find columns in a specific table, use the following query:

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YourTableName'
AND TABLE_CATALOG = 'YourDatabaseName';

Replace ‘YourTableName’ and ‘YourDatabaseName’ with the appropriate names.

Using SQL Server Management Studio

SQL Server Management Studio (SSMS) is a powerful graphical tool for managing your SQL Server databases. It offers an easy way to find tables and columns in SQL Server.

Finding Tables

To find tables in SSMS, follow these steps:

1. Connect to your SQL Server instance.
2. Expand the “Databases” folder.
3. Expand the database you want to search.
4. Expand the “Tables” folder to see a list of all tables.

Finding Columns

To find columns in SSMS, follow these steps:

1. Follow the steps above to locate the table you want to inspect.
2. Expand the table.
3. Click on the “Columns” folder to view all columns in the table.

Using T-SQL Queries

T-SQL (Transact-SQL) is the SQL dialect used in SQL Server. You can use T-SQL queries to find tables and columns in your database.

Finding Tables

To find tables in SQL Server using T-SQL, execute the following query:

SELECT name
FROM sys.tables
WHERE name LIKE '%YourSearchTerm%';

Replace ‘YourSearchTerm’ with the term you want to search for.

Finding Columns

To find columns in SQL Server using T-SQL, execute the following query:

SELECT name
FROM sys.columns
WHERE object_id = OBJECT_ID('YourTableName')
AND name LIKE '%YourSearchTerm%';

Replace ‘YourTableName’ and ‘YourSearchTerm’ with the appropriate values.

What is T-SQL and how can it help me find tables and columns in SQL Server?

T-SQL (Transact-SQL) is the SQL dialect used in SQL Server. It is an extension of the standard SQL language, providing additional features specific to SQL Server. You can use T-SQL queries to find tables and columns in your database by querying system catalog views, such as sys.tables and sys.columns.

Can I search for specific table or column names in SQL Server?

SELECT name
FROM sys.tables
WHERE name LIKE '%customer%';

Similarly, to search for columns with the word “email” in their name, you can use the following query:

SELECT name
FROM sys.columns
WHERE object_id IN (SELECT object_id FROM sys.tables)
AND name LIKE '%email%';
