What is index by binary integer?
Index-By Tables (Associative Arrays)
The first type of collection is known as index-by tables. … As the name implies, the collection is indexed using BINARY_INTEGER values, which do not need to be consecutive. The collection is extended by assigning values to an element using an index value that does not currently exist.
What is binary data in Oracle?
When Oracle automatically converts RAW or LONG RAW data to and from CHAR data, the binary data is represented in hexadecimal form with one hexadecimal character representing every four bits of RAW data. For example, one byte of RAW data with bits 11001011 is displayed and entered as ‘CB’.
Is integer PL SQL?
Integer datatype conforming to your hardware’s underlying integer representation. Arithmetic is performed with your hardware’s native machine instructions. You cannot store values of this type in tables; it is a PL/SQL-specific datatype.
What is difference between PLS_INTEGER and integer?
Answer: For integer values, the PLS_INTEGER type gives better performance and requires less storage space than either INTEGER or NUMBER types. … It is a good practice to use PLS_INTEGER versus NUMBER. The PLS_INTEGER data Type was introduced in PL/SQL version 2.2 and has a range of -2147483647 to 2147483647.
Can PLS_INTEGER be null?
Natural: This type uses the non-negative values of the PLS_INTEGER range. i.e., 0 to +2,147,483,647 and Null. … i.e., 1 to +2,147,483,647 and Null values.
Where is Varray stored?

What is binary data type?
In statistics, binary data is a statistical data type consisting of categorical data that can take exactly two possible values, such as “A” and “B”, or “heads” and “tails”. … Often, binary data is used to represent one of two conceptually opposed values, e.g: the outcome of an experiment (“success” or “failure”)
What is binary float in Oracle?
BINARY_FLOAT is a single-precision native floating-point type that supports +Inf , -Inf , and NaN values. BINARY_FLOAT is an approximate numeric value consisting of an exponent and mantissa. You can use exponential or E-notation. BINARY_FLOAT has binary precision 24. Minimum positive finite value: 1.17549E-38F.
What is type in PL SQL?
The %TYPE attribute, used in PL/SQL variable and parameter declarations, is supported by the data server. Use of this attribute ensures that type compatibility between table columns and PL/SQL variables is maintained. … If the data type of the column or variable changes, there is no need to modify the declaration code.
