What is string data type in Informatica?
The transformation string datatypes include Nstring, Ntext, String and Text. Although the Nstring, Ntext, String, and Text datatypes support the same precision up to 104,857,600 characters, Data Integration. uses String to move string data from source to target and Text to move text data from source to target.
What is use of string data type?

What is precision and scale in Informatica?
Precision is the maximum number of significant digits for numeric data types, or the maximum number of characters for string data types. Precision includes scale. Scale is the maximum number of digits after the decimal point for numeric values. Therefore, the value 11.47 has a precision of 4 and a scale of 2.
What is Oracle datatype?

In C programming, we can use char data type to store both character and string values.
What is double data type in Informatica?
When you enable high precision and the port precision is greater than 38 digits or 28 digits, depending on the transformation, the Data Integration Service stores the result as a double. Double. Double-precision floating-point numeric value. You can edit the precision and scale.
What is string data type in SQL?
The string data types are CHAR , VARCHAR , BINARY , VARBINARY , BLOB , TEXT , ENUM , and SET . In some cases, MySQL may change a string column to a type different from that given in a CREATE TABLE or ALTER TABLE statement. See Section 13.1.
What is the function of a string?
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
How do you use strings?
Commonly Used String Functions
- strlen() – calculates the length of a string.
- strcpy() – copies a string to another.

- strcat() – concatenates two strings.
What is the value of string data type?
The default value of String is Nothing (a null reference).
Should I use string or char?
There is no reason to use char* when you need a string — unless your primitive strings are fixed on the stack or compiled in and the profiler said that’s how they should be. Advising to use a char* over a string is roughly never a good advice if the profiler didn’t say the same thing.
