There are two basic types of data conversions: manual and electronic. Each have benefits and are appropriate in different situations.
How do I convert a string to an int in SSIS?
Try applying a combination of DECIMAL and FLOAT. I tried a test of this and it worked. This first converts to a float and then to a decimal. But if you need to convert the string to an integer (as defined in the title of your question), then apply (DT_I4)TRIM(NAME1).
How do you convert data type?
Data types can be converted either implicitly or explicitly. Implicit conversions are not visible to the user. SQL Server automatically converts the data from one data type to another. For example, when a smallint is compared to an int, the smallint is implicitly converted to int before the comparison proceeds.

What is the difference between data conversion and data migration?
While database conversion is basically the transformation of data from one format to another, database migration is the process of moving data from one source, format or system to another. Data migration usually requires quality assurance processes by the target source, such as data validation, cleansing and profiling.
Can one type of data be converted into other give an example?
Answer. Explanation: Converting one datatype into another is known as type casting or, type-conversion. For example, if you want to store a ‘long’ value into a simple integer then you can type cast ‘long’ to ‘int’.
What is int data type in SSIS?
int. four-byte signed integer. (DT_I4) int. eight-byte signed integer.
What is Nvarchar vs varchar?
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.
Which transformation would you use to change the data type of the input column to match your destination column?
Conditional Split: This transformation is used to accepts input and determine which destination to pipe the data into based on the result of an expression. It redirects rows of data that meet specific conditions to different outputs.

What converts to long data type?
We can convert int to long in java using assignment operator. There is nothing to do extra because lower type can be converted to higher type implicitly. It is also known as implicit type casting or type promotion.
What is difference between cast and convert in SQL?
The CAST function is used to convert a data type without a specific format. The CONVERT function does converting and formatting data types at the same time.
