sql server - SSIS - Data consistency check -


I've been working with SSIS recently, I've created a flow of work with the next specification:

Enter image details here

I use a derived column in this case I am doing this because there are some dates like '0001-01-31' and '1500-02-031' from Oracle source, and these dates are to be changed in these dates '19 00-01-01' (I used it That has expresion: [date] <(DT_DBDATE) "1900-0 1-01 "? (DT_DBDATE)" 1901-01-01 ": [date]). Because the first kind of dates are not allowed by the SQL database, and I can not change the specification of the data types of columns.

The problem is that when I look at the data flow at the end, execution shows that 9.958 rows have been entered in the destination, but by creating a query with a number, the database is selected in SQL , I have the figure 9.956. According to I, the rows on this date have not been modified by the process.

So, I would like to know why this is happening, and if there is any way to get the results that I am looking for in Thanks
