Snowflake Vs MS-SQL - Part 82 - Generate Unique Identifier

           


Generate Unique Identifier

Sometimes, we need to generate a unique identifier and use it consistently throughout our code.

MS-SQL Server 

We can achieve it by using built-in functions as follows:




In Snowflake, we can use a similar function, UUID_STRING (), as below:




For more details, refer to the UUID_STRING section.

Snowflake Vs MS-SQL - Part 63 - ON Clause & Cross Join

Image
          ON Clause & Cross Join We use different joins to pull the records from multiple tables. We need to use the ON clause along with JOIN. What will happen if we don't use the ON clause? MS-SQL Server   If we don't mention the ON clause, it throws an error. However, if we use the same column from the same table on both sides, it works as a cross-join.  Also, if you mention condition as 1=1 in the ON clause, it treats as CROSS JOIN. However, in  Snowflake,  both above queries will work.  Apart from this, if you don't mention the ON clause, it treats it as CROSS JOIN: Yogesh Shinde LinkedInProfile <<< Back   Next >>>

        UNION By Name Sometimes, we have to combine data from multiple tables. In this case, we can use UNION. However, the catch is that the order of the columns should be the same. MS-SQL Server   We can achieve this by using UNION as below: In  Snowflake,  we can use  the same query as above; however, we have to use the same column order in the select clause. However, we can use  UNION BY Name   as below. The order of the columns in the  select clause does not matter. NOTE: Similarly, you can use  UNION ALL BY NAME .

Snowflake Vs MS-SQL - Part 68 - Multi Table Insert

Image
         Multi Table Insert We insert data into a table, and sometimes, we must archive/back it up in another table. MS-SQL Server   We can achieve this by using magic or virtual tables present, like INSERTED,  as below: However, in  Snowflake, the insert statement has an additional clause,  INSERT ALL,  which allows you to insert into multiple tables:  For more details, you can refer to the following:  Multi_Table_Insert .
