Display Line Numbers In SQL Queries

Display Line Numbers In SQL Queries

By default in SQL Query analyzer line numbers are not shown.

Follow the steps below:

GOTO:  Tools => Text Editor =>All Languages => General =>Line Number (Select this check box).

Now when you open a “New Query” line numbers will appear.

Saving change is not permitted

Saving change is not permitted

Some time if your setting changed by some one then you can not update table in MSSQL 2008.
you will see the below error:

“A table that can not be re-created or enabled the options prevent saving changes.
Sql 2008 Management Tools: Can’t save changes that require Recreation of Database”

That time you need to update your setting.

The fix is:

Go to Tools => Options => Designers =>Tables and Designers and uncheck the Prevent Saving Changes that require table re-creation option:

As it is, reverting back to the ‘old’ behavior now doesn’t let you know that a table recreate is required either, so the behavior now is the same as was with the old tools. Here Microsoft added some useful functionality and then UI fails to expose it intelligently.

MERGE (Transact-SQL)

MERGE (Transact-SQL 2008)

MERGE is new feature , it Performs insert, update, or delete operations on a target table based on the results of a join with a source table. For example, you can synchronize two tables by inserting, updating, or deleting rows in one table based on differences found in the other table.

Examples

CREATE TABLE TABLE1
(
Monthid INTEGER,
Month_Name VARCHAR(15)
)
GO
INSERT INTO TABLE1
VALUES(1,'JAN')
INSERT INTO TABLE1
VALUES(2,'FEB')
INSERT INTO TABLE1
VALUES(3,'MAR')
INSERT INTO TABLE1
VALUES(4,'APR')
INSERT INTO TABLE1
VALUES(5,'MAY')
GO

CREATE TABLE TABLE2
(
Monthid INTEGER,
Month_Name VARCHAR(15)
)
GO
INSERT INTO TABLE2
VALUES(1,'JAN')
INSERT INTO TABLE2
VALUES(6,'JUNE')
INSERT INTO TABLE2
VALUES(7,'JULY')

select * from TABLE2
select * from TABLE1

MERGE TABLE1 AS t1
USING (SELECT Monthid,Month_Name FROM TABLE2) AS t2
ON t1.Monthid = t2.Monthid
WHEN MATCHED AND t1.Monthid > 8 THEN DELETE
WHEN MATCHED THEN UPDATE SET t1.Monthid = t2.Monthid
WHEN NOT MATCHED THEN
INSERT(Monthid,Month_Name)
VALUES(Monthid,Month_Name);
GO

MSDN:
Using MERGE to perform INSERT and UPDATE operations on a table in a single statement

A common scenario is updating one or more columns in a table if a matching row exists, or inserting the data as a new row if a matching row does not exist. This is usually done by passing parameters to a stored procedure that contains the appropriate UPDATE and INSERT statements. With the MERGE statement, you can perform both tasks in a single statement. The following example shows a stored procedure that contains both an INSERT statement and an UPDATE statement. The procedure is then modified to perform the equivalent operations by using a single MERGE statement.
