Prompt Title: Redshift execute dynamic SQL.

To execute dynamic SQL in Redshift, you can use a combination of SQL string manipulation and the EXECUTE command.

Here's an example of how you can write a Redshift query to execute dynamic SQL:

sqlCopy code
DECLARE
  sql_statement VARCHAR(1000);

BEGIN
  -- Construct the dynamic SQL statement
  sql_statement := 'SELECT * FROM ' || schema_name || '.' || table_name || ' WHERE ' || condition;

  -- Execute the dynamic SQL statement
  EXECUTE sql_statement;
END;

In this example, we first declare a variable sql_statement to hold the dynamic SQL statement that we want to execute. We then use string concatenation to build the SQL statement by combining the schema_name, table_name, and condition variables.

Finally, we use the EXECUTE command to execute the dynamic SQL statement.

Note that in order to execute dynamic SQL in Redshift, you'll need to have the necessary permissions to execute the SQL statements that you're constructing. Also, be careful when constructing dynamic SQL statements to avoid SQL injection vulnerabilities.
