This code is converting the [SLIPDATE] column, which is likely a date or datetime data type, to a string in the format yyyymmdd using the 112 style code.
The 112 style code is one of many style codes used in SQL Server to specify the format of a date or datetime value when converting it to a string.
In this case, the resulting string will have the year first, followed by the month and then the day, with no separators between them. For example, if [SLIPDATE] is '2021-05-27', the resulting string will be '20210527'.
The purpose of this conversion may be to make it easier to perform certain types of comparisons or calculations with the date values, or to display them in a specific format for reporting purposes.
