What is the equivalent of 'describe table' in SQL Server?

You can use the sp_columns stored procedure:

exec sp_columns MyTable

---

There are a few methods to get metadata about a table:

EXEC sp_help tablename

Will return several result sets, describing the table, it's columns and constraints.

The INFORMATION_SCHEMA views will give you the information you want, though unfortunately you have to query the views and join them manually.

---

Just in case you don't want to use stored proc, here's a simple query version

select * 
  from information_schema.columns 
 where table_name = 'aspnet_Membership'
 order by ordinal_position

---

You can use following: sp_help tablename

Example: sp_help Customer

OR Use Shortcut Keys

Select the desired table and press ALT+F1.

Example: Customer Press ALT+F1.

---

Use this Query

Select * From INFORMATION_SCHEMA.COLUMNS Where TABLE_NAME = 'TABLENAME'

---

In addition to the ways shown in other answers, you can use

SELECT TOP 0 * FROM table_name

This will give you the name of each column with no results in them, and completes almost instantly with minimal overhead.

---

Please use the following sql query; this worked for my case.

select * FROM   INFORMATION_SCHEMA.Columns where table_name = 'tablename';

---

Just select table and press Alt+F1,

it will show all the information about table like Column name, datatype, keys etc.

I wrote an sql*plus DESC(RIBE) like select (displays the column comments, too) in t-sql:

USE YourDB
GO

DECLARE @objectName NVARCHAR(128) = 'YourTable';

SELECT

 ,a.[TYPE]
 ,a.[CHARSET]
 ,a.[COLLATION]
 ,a.[NULLABLE]

     ,CASE DATA_TYPE
        WHEN 'char'       THEN DATA_TYPE  + '(' + CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) + ')'

The above mentioned select can be used in a system marked stored procedure and it can be called from any database of your instance on a simple way:

  SELECT @dbName = PARSENAME(@tableName, 3);
  IF @dbName IS NULL SELECT @dbName = DB_NAME();

  SELECT @schemaName = PARSENAME(@tableName, 2);
  IF @schemaName IS NULL SELECT @schemaName = SCHEMA_NAME();

  SELECT @objectName = PARSENAME(@tableName, 1);

    --PRINT @sqlCmd;

    EXEC sp_executesql @sqlCmd;
    RETURN;
END;
GO

EXEC sys.sp_MS_marksystemobject sp_desc
GO

To execute the procedure type:

EXEC sp_desc 'YourDB.YourSchema.YourTable';

If you want to get a description an object of the current database (and schema) simple type:

EXEC sp_desc 'YourTable';

As sp_desc is a system marked procedure, you can even leave the exec command, too (not recommended anyway):

sp_desc 'YourTable';

---

The SQL Server equivalent to Oracle's describe command is the stored proc sp_help

The describe command gives you the information about the column names, types, length, etc.

In SQL Server, let's say you want to describe a table 'mytable' in schema 'myschema' in the database 'mydb', you can do following:

USE mydb;
exec sp_help 'myschema.mytable';

---

You can use the sp_help 'TableName'

---

try it:

EXEC [ServerName].[DatabaseName].dbo.sp_columns 'TableName'

and you can get some table structure information, such as:

TABLE_QUALIFIER, TABLE_OWNER, TABLE_NAME, COLUMN_NAME, DATA_TYPE, TYPE_NAME...

---

In addition to above questions, if we have table in DB like db_name.dbo.table_name, we may use following steps

Connect with DB USE db_name; Use EXEC sp_help and don't forget to put table name as 'dbo.tablename' if you have dbo as schema. exec sp_help 'dbo.table_name'

This should work!

---

I tried this and it's working for me

exec sp_help TABLE_NAME

---

The problem with those answers is that you're missing the key info. While this is a bit messy this is a quick version I came up with to make sure it contains the same info the MySQL Describe displays.

Select SC.name AS 'Field', ISC.DATA_TYPE AS 'Type', ISC.CHARACTER_MAXIMUM_LENGTH AS 'Length', SC.IS_NULLABLE AS 'Null', I.is_primary_key AS 'Key', SC.is_identity AS 'Identity'
From sys.columns AS SC 
LEFT JOIN sys.index_columns AS IC
ON IC.object_id = OBJECT_ID('dbo.Expenses') AND 
IC.column_id = SC.column_id
LEFT JOIN sys.indexes AS I 
ON I.object_id = OBJECT_ID('dbo.Expenses') AND 
IC.index_id = I.index_id
LEFT JOIN information_schema.columns ISC
ON ISC.TABLE_NAME = 'Expenses'
AND ISC.COLUMN_NAME = SC.name
WHERE SC.object_id = OBJECT_ID('dbo.Expenses')

First connect to your DB,

use DB_name

Then

exec sp_help 'Production.Et_Issue'

here 'production' is the schema name. If you dont have a schema, you may simply write sp_help table_name

https://i.stack.imgur.com/Hp57F.png

---

use

SELECT COL_LENGTH('tablename', 'colname')

None of other solution worked for me.

---

SELECT C.COLUMN_NAME, C.IS_NULLABLE, C.DATA_TYPE, TC.CONSTRAINT_TYPE, C.COLUMN_DEFAULT
    FROM INFORMATION_SCHEMA.COLUMNS AS C
    FULL JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE AS CC ON C.COLUMN_NAME = CC.COLUMN_NAME 
    FULL JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS TC ON CC.CONSTRAINT_NAME = TC.CONSTRAINT_NAME
WHERE C.TABLE_NAME = '<Table Name>';

Sample Output

---

If you are using FirstResponderKit from Brent Ozar team, you can run this query also:

exec sp_blitzindex @tablename='MyTable'

It will return all information about table:

indexes with their usage statistics(reads, writes, locks, etc), space used and other

missing indexes

columns

foreign keys

statistics contents

Of course it's not a system and not so universal stp like sp_help or sp_columns, but it returns all possible information about your table and I think it's worth creating it at your environment and mentioning it here.

Just double click on the table name and press Alt+F1
