5 min readThe char(7) data type in Teradata SQL represents a fixed-length character string with a length of 7 characters. When used in the context of a date format, it is typically used to store date values in the format 'YYYYMMDD'. This allows for dates to be represented in a compact and efficient manner, making it easy to manipulate and compare date values in SQL queries.[rating:233766ea-dc8c-4894-8eb7-12a445728045]How to handle date format conversions with char(7) columns in Teradata SQL.

5 min readTo find duplicates from multiple tables at once in Teradata, you can use the SELECT statement along with the GROUP BY and HAVING clauses. First, you need to join the tables using the appropriate keys to link the records from different tables together. Then, you can use the GROUP BY clause to group the records based on common attributes. Finally, you can use the HAVING clause to filter out the groups that have more than one record, indicating the presence of duplicates.

5 min readTo properly include an rd.xml file in a NuGet package, you first need to ensure that the rd.xml file is included in the project that you want to package. Once the rd.xml file is included in the project, you can configure the NuGet package to include the file during the packaging process.You can achieve this by adding the rd.xml file to the project's .csproj file as an additional file that should be included in the NuGet package. You can do this by editing the .
