Hello,
I map "date" information obtained from the Excel source in SSIS (1.3.2 version) through the Data Conversion Transformation Editor with the 'database date' data type
In Date Lookup Transformation Editor, I use the Date_Dim table and the data type of the full_date attribute in this table is "date" as well. However, I get a warning like the one below.
I
interestingly full_date can be matched with Copy of competiton_id in the Unicode String DT-WSTR. Could you help me, please?
*I also tried the following SQL commands in Lookup, but it does not work.
SELECT
DateKey,
CAST(full_date AS DATE) AS full_date,
day_name,
month,
year
FROM
Date_Dim;
Unfortunately, it's truncated in the screenshot but is it definitely DT_DBDATE (not any of the other ones that are similar). Also in the lookup screen, hover over each of the columns, and it should show you the data types that it thinks are being used.
---------------
*Thank you. it was database date[DT-DBDATE]
In order to match full_date with Copy of Date, I am required to select Copy of Date as Unicode String [DT-WSTR] in the Data Conversion Transformation Editor. However, when I execute it in this manner, I receive the following warnings.

2)When I try the following commands in the Date lookup
SELECT
DateKey,
CONVERT(varchar(8), full_date, 112) AS full_datenew,
day_name,
month,
year
FROM
Date_Dim;
Then, to match Copy of Date for the lookup, I need to map Copy of Date to String [DT-STR] in the Data Conversion Transformation Editor. However, the process fails when I run it.
3I'm new to this, what I don't understand is, although the full_date in the Date_Dim table is in the date data type, it appears in a different data type in the Lookup. Also, if I ignore the Date operation, my Run process is successful, but DateKey is a required column.
What you could also do is make the value on each side be a 'YYYYMMDD' string. SQL Server gets them right every time. (It's the best date literal format). On the SQL Server lookup side, you can get that by CONVERT(varchar(8), column, 112)
Normally, I don't need information in the format hh:mm:ss within the date for my project. I used database timestamp instead of date[DT-DBDATE] in the Data Conversion Transformation Editor for the issues.
I executed the following commands in Date Lookup. I mapped Copy of Date to full_date. and SSIS ran successfully
SELECT
DateKey,
CAST(full_date AS smalldatetime) AS full_date,
day_name,
month,
year
```FROM
Date_Dim;
