This might be useful as well.

SELECT SS.NAME AS [TABLE_SCHEMA], ST.NAME AS [TABLE_NAME]
, SKC.NAME AS [CONSTRAINT_NAME], SC.NAME AS [CONSTRAINT_COLUMN_NAME],
CAST(STY.NAME AS VARCHAR(20)) +’(‘+
CAST(CASE ST.NAME
WHEN ‘NVARCHAR’ THEN (SELECT SC.MAX_LENGTH/2)
ELSE (SELECT SC.MAX_LENGTH)
END AS VARCHAR(20)) +’)’ AS [DATA_TYPE]
FROM SYS.KEY_CONSTRAINTS AS SKC
INNER JOIN SYS.TABLES AS ST
ON ST.OBJECT_ID = SKC.PARENT_OBJECT_ID
INNER JOIN SYS.SCHEMAS AS SS
ON SS.SCHEMA_ID = ST.SCHEMA_ID
INNER JOIN SYS.INDEX_COLUMNS AS SIC
ON SIC.OBJECT_ID = ST.OBJECT_ID
AND SIC.INDEX_ID = SKC.UNIQUE_INDEX_ID
INNER JOIN SYS.COLUMNS AS SC
ON SC.OBJECT_ID = ST.OBJECT_ID
AND SC.COLUMN_ID = SIC.COLUMN_ID
INNER JOIN SYS.TYPES AS STY
ON SC.USER_TYPE_ID = STY.USER_TYPE_ID
ORDER BY TABLE_SCHEMA, TABLE_NAME, CONSTRAINT_NAME;

how I can use join query to fetch the unique data from two or more than two table

if Table A has column a1,a2,a3,a4,a5

Table B has column a1,a2,a3,b1,b2

Table C has column a1,a2,a3,c1,c2

where a1 is primary key for each table

I want to use * since number of column may be any number
in the other table so the value a1,a2,a3 get repeated for every table.how I can get only unique value in my query result a1,a2,a3 should not get repeated…….

You need to open the table in design mode then right click on that column

I was trying to add primary key to existing table. When I right click after selecting the columns, ‘set primary key’ option is not active. Do you know what’s going on. I am a beginner using SQL server management studio.

Great thanks Pinal Dave!! Your writings are always very useful for me.
I want to ask, can we find the index columns of the primary key? Can somebody help me please…

how I could add two primary key in sql 2005 ?

for example I have this table

ECE_Activities
—————=
Act_id int Not Null
Act_sec_id int Not Null
Act_name varchar
Act_min_balance

I want to “Act_id” and “Act_sec_id” to make both of them primary key.

You have been a wonderful teacher. I call myself as Pinal Dave’s Student.

What I do is not even comparable with what you have been doing to help SQL Community. Again Thanks for appreciating my work, I see many other people helping other members on this website, One among them whom I know ( through website) is “Emeka”

Excellent work Dear.

Thanks,
Imran.
