Question:
I’m writing a select statement to make a table name a variable whose value is set according to a condition:
Var tablename;tablename := emp tableselect * from tablename;
But I get an error message. How do I make this statement work?
Answer:
Your syntax is close to what you need. But you need to call the EXECUTE command with the SQL string. Here’s code you can run in Query Analyzer that uses a variable for the table name and retrieves all the records from the Employees table:
DECLARE @TableName varchar(255)SET @TableName = 'Employees'EXEC ('SELECT * FROM ' + @TableName)
