If the flat file source is Unicode, the Flat File connection manager defines all columns as [DT_WSTR] with a default column width of 50. If the flat file source is ANSI-encoded, the columns are defined as [DT_STR] with a column width of 50.
What is the type of INT?
int: By default, the int data type is a 32-bit signed two’s complement integer, which has a minimum value of -231 and a maximum value of 231-1. In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 232-1.
How does varchar Max handle SSIS?
Using Script Component to Parse Column Values 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.
