Hello guys

I have a store procedure with a parameter that I will pass a table,

how can I run this table in store procedure that I passed by parameter.

example


exect run_table "nome_table"

inside the store procedure

select * from @table

but this way it doesn't work, I think it must be a string of script

how do that?

thanks

Can you create your variable table within your stored procedure, or create your table as a temp table instead and just reference it directly in your sp?

Hi,

Inside the stored procedure instead of

select * from @table

Open in new window

write
EXEC('SELECT * FROM ' + @table)

Open in new window

--with @tables like with variables - try run just:

SELECT @table;

--instead...

if you want to pass a table name to a  stored procedure and then have the procedure
run query against that table then you basically need to use dynamic sql in the query...

however it is a security issue to have such a generalised stored procedure , and normally as a solution is strongly not recommended.

declare @sql varchar(1000)

set @sql='Select * from '+@table_name_parameter

exec(@sql)

would be one way to achieve it
