DROP TABLE IF EXISTS” in Oracle and SQL Server

“DROP TABLE IF EXISTS” in Oracle and SQL Server

In MySQL it is pretty easy to drop a table if it exists already. In Oracle and Microsoft’s SQL Server it is a little more complicated. Today I want to present you the solutions for these two DBMS’.

MySQL:

DROP TABLE IF EXISTS [table_name]

Oracle:

BEGIN      EXECUTE IMMEDIATE 'DROP TABLE [table_name]';      EXCEPTION WHEN OTHERS THEN NULL;  END;

SQL Server:

IF EXISTS (      SELECT  TABLE_NAME FROM INFORMATION_SCHEMA.TABLES      WHERE   TABLE_NAME = '[table_name]')  DROP TABLE  [table_name]
