What is Wstr in SSIS?
SSIS connects to your data sources and checks their data types. If you see WSTR then you have a NVARCHAR (unicode compatible) column in SQL Server or a unicode column in oracle. If both are WSTR then you don't have to convert.Mar 19, 2018
What is Dt_ntext in SSIS?
Since the column is a VARCHAR(MAX) data type in SQL Server, SSIS treats this as a DT_TEXT datatype. The DT_TEXT and DT_NTEXT are text data types and there are several limitations related to handling these datatypes in SSIS. For example, none of the string functions would work with these data types.Nov 6, 2017
What is non Unicode data?
Unicode. (char, varchar, text) (nchar, nvarchar, ntext) Stores data in fixed or variable length.Jan 25, 2011
What is the difference between varchar and nvarchar?
The key difference between varchar and nvarchar is the way they are stored, varchar is stored as regular 8-bit data(1 byte per character) and nvarchar stores data at 2 bytes per character. Due to this reason, nvarchar can hold upto 4000 characters and it takes double the space as SQL varchar.May 29, 2019
What is multicast in SSIS?
Multicast Transformation in SSIS sends input data to multiple destination paths without applying any conditions or transformations. OR, Takes ONE Input and makes the logical COPY of data and passes the same data to multiple outputs.
What is Dt_date in SSIS?
DT_DATE. A date structure that consists of year, month, day, hour, minute, seconds, and fractional seconds. The fractional seconds have a fixed scale of 7 digits. The DT_DATE data type is implemented using an 8-byte floating-point number.Aug 17, 2020
What is Unicode with example?
The code point is a unique number for a character or some symbol such as an accent mark or ligature. Unicode supports more than a million code points, which are written with a "U" followed by a plus sign and the number in hex; for example, the word "Hello" is written U+0048 U+0065 U+006C U+006C U+006F (see hex chart).
What is the difference between Unicode and non Unicode types?
The only difference between the Unicode and the non-Unicode versions is whether OAWCHAR or char data type is used for character data. The length arguments always indicate the number of characters, not the number of bytes. OAWCHAR is mapped to the C Unicode data type wchar_t.
What is a Unicode database?
A Unicode database is a database with a UTF-8 character set as the database character set. There are three Oracle character sets that implement the UTF-8 encoding. The first two are designed for ASCII-based platforms while the third one should be used on EBCDIC platforms.
Why NVARCHAR is used?
The real reason you want to use NVARCHAR is when you have different languages in the same column, you need to address the columns in T-SQL without decoding, you want to be able to see the data "natively" in SSMS, or you want to standardize on Unicode.
What is a NVARCHAR in SQL?
The NVARCHAR data type stores character data in a variable-length field. Data can be a string of single-byte or multibyte letters, digits, and other characters that are supported by the code set of your database locale.
What is NVARCHAR in SQL example?
The syntax for declaring the nvarchar variable is nvarchar(n), where n defines the string size in byte-pairs. The value of n must be from 1 through 4000. For Example, when we store a string of length 10, The string will occupy (10*2) + 2 (=22 bytes) bytes of storage.
What is DT_DBTIMESTAMP?
On the other hand, DT_DBTIMESTAMP is represented by a structure that internally has individual fields for year, month, day, hours, minutes, seconds, and milliseconds. This data type has larger limits on ranges of the dates it can present.
What is DT_DATE data type?
The DT_DATE data type is implemented using an 8-byte floating-point number. Days are represented by whole number increments, starting with 30 December 1899, and midnight as time zero. Hour values are expressed as the absolute value of the fractional part of the number. However, a floating point value cannot represent all real values; therefore, there are limits on the range of dates that can be presented in DT_DATE.
What is a timestamp structure?
A timestamp structure that consists of year, month, day, hour, minute, second, and fractional seconds. The fractional seconds have a maximum scale of 7 digits.
When data enters a data flow in a package, the source that extracts the data converts the data
When data enters a data flow in a package, the source that extracts the data converts the data to an Integration Services data type. Numeric data is assigned a numeric data type, string data is assigned a character data type, and dates are assigned a date data type. Other data, such as GUIDs and Binary Large Object Blocks (BLOBs), are also assigned appropriate Integration Services data types. If data has a data type that is not convertible to an Integration Services data type, an error occurs.
Why is each row of data narrower?
Making each data row as narrow as possible helps optimize performance when transferring data because the narrower each row is, the faster the data is moved from source to destination.
What format is DT_DATE?
When a string is cast to a DT_DATE, or vice versa, the locale of the transformation is used. However, the date is in the ISO format of YYYY-MM-DD, regardless of whether the locale preference uses the ISO format.
How many digits are in DT_DBTIME2?
(The DT_DBTIME2 data type can have between 0 and 7 digits specifi ed for fractional seconds.)
What is a DT_WSTR?
UniCode string [DT_WSTR] as Data type for mycolumn in Data Conversion Component.
What happens if there are some non-numeric values in DT_WSTR data type column?
If there are some non-numeric values in DT_WSTR data type column, the conversion (DT_I8)myColumn would be failed.

I'm new to SSIS trying to covert data types. I'm pulling data from Google Analytics and loading data into a SQL 2008 database. The date column from Google analytics appears as "DT_WSTR" and the values are in the format "20130402" (year:month:day). I want to change the format to a date format so i can load it into a date field in my database.
