use a table as a variable
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I was wondering if there was a way to set a table name in SQL to be a variable.
I have a list of queries that hit the same table and didn't want to have to update them all so was hoping to declare the table name as a value.
Below is an example: what I wanted to do is declare the table name once and use the @tablename in the queries shown below.
/*at the field level */
SELECT
(
SELECT COUNT(DISTINCT PROVIDER_TIN) AS PROVIDER_TIN
from [Coloma].[dbo].Aetna_Medicare_2019 a
WHERE PROVIDER_TIN = '' OR PROVIDER_TIN IS NULL
) AS NULL_TINS,
(
SELECT COUNT(DISTINCT PROVIDER_ID) AS PROVIDER_ID
from [Coloma].[dbo].Aetna_Medicare_2019 a
WHERE PROVIDER_ID = '' OR PROVIDER_ID IS NULL
) AS NULL_IDS
