[@fullstacktutorials2883]

You have missed to explain difference between joins and union:
In simple terms, joins combine data into new columns. If two or more tables are joined together, then the data from the first table is shown in one set of column alongside the second table’s column in the same row and so on.
Unions combine data into new rows. If two or more tables are “unioned” together, then the data from the first table is in one set of rows, and the data from the second table in another set and so on.the rows are in the same result.

thanks !!

[@mahe6816]

@@bcoa57amaykhatri94 Joins are Used to retrive the data from multiple tables in a single time
Where as the union is used to combine multiple SQL statements into single SQL statements
In joins comparision Happens Vertically
In union comparision Horizontally
For apply join between two table we need some matching from both the table
For apply Union between two tables we need some prerequisites.

Create procedure based on 2 parameters are state and city.
1. If I pass state then get employee details state wise
2. If I pass city then get employee details city wise
3. If I pass both then get employee details of state and city.

[@CRVgarage]

Create a procedure with state & city parameters. Inside the procedure, write select statements using IF, ELSE IF & ELSE. So based on the parameters passed by the user, respective select statements get executed. Hope it helps.

[@ashokdevendra8978]

dai .................

[@katurimahesh6835]

We can use transaction commands (rollback, commit ) in truncate

Can anyone please tell me how to give the table name dynamically in SELECT query. Thanks in advance.

You to need to create table or check the table?

[@sunnydoon]

use dynamic SQL quires
DECLARE @sqlCommand varchar(1000)
DECLARE @tableName varchar(75)
SET @tableName = '''Employee'''
SET @sqlCommand = 'SELECT * from ' + @tableName
EXEC (@sqlCommand)
