SQL Interview Question | How to find Sandwich Pattern Numbers in a table| Oracle | Snowflake |MS SQL

In this video, as part of the SQL Interview Questions series, I am going to show you how to Write a SQL query to retrieve records where the number is a single-digit sandwich number. What Are Sandwich Pattern Numbers? A Sandwich Pattern Number is a number or a sequence that follows a specific symmetrical structure, where a digit (or group of digits) is sandwiched between identical digits on both sides. Think of it like a sandwich: The bread is the same on both ends (e.g., same digit). The filling is a different digit or set of digits in the middle -- Examples 121 → 1 is on both ends and 2 is in the middle. 212 → 1 is on both ends and 1 is in the middle. 343 → 3 is on both ends and 4 is in the middle. ⌚Timestamps 00:00 Question 06:57 Query from MS SQL Server 13:25 Query from Oracle Database 23ai 19:07 Query from Snowflake Cloud Data Warehouse 24:16 Query from Databricks SQL 31:37 Outro
