What will be the default size of number data type?
What will be the default size of number data type?
In SQL Server, the default maximum precision of numeric and decimal data types is 38. In earlier versions of SQL Server, the default maximum is 28. Length for a numeric data type is the number of bytes that are used to store the number. For varchar and char, the length of a character string is the number of bytes.
What is the range of number data type in Oracle?
Numeric Datatypes
| Data Type Syntax | Oracle 9i |
|---|---|
| number(p,s) | Precision can range from 1 to 38. Scale can range from -84 to 127. |
| numeric(p,s) | Precision can range from 1 to 38. |
| float | |
| dec(p,s) | Precision can range from 1 to 38. |
What is default precision of number in Oracle?
Converting to Oracle Datatypes The NUMBERIC and DECIMAL datatypes can specify only fixed-point numbers. For those datatypes, s defaults to 0. The FLOAT datatype is a floating-point number with a binary precision b. The default precision for this datatypes is 126 binary, or 38 decimal.
What is the data type of 12?
data type
| Data Type | Used for | Example |

| Float (floating point) | Number with a decimal point | 3.15, 9.06, 00.13 |
| Character | Encoding text numerically | 97 (in ASCII, 97 is a lower case ‘a’) |
| Boolean | Representing logical values | TRUE, FALSE |
What is the default length of a char column in Oracle?
When you create a table with a CHAR column, you must specify a string length (in bytes or characters) between 1 and 2000 bytes for the CHAR column width. The default is 1 byte. Oracle then guarantees that: When you insert or update a row in the table, the value for the CHAR column has the fixed length.
What is precision and scale in the Oracle number data type?
The Oracle NUMBER data type has precision and scale. The precision is the number of digits in a number. The scale is the number of digits to the right of the decimal point in a number.
What is the default string length for char data type?
The CHAR datatype stores fixed-length character strings. When you create a table with a CHAR column, you must specify a string length (in bytes or characters) between 1 and 2000 bytes for the CHAR column width. The default is 1 byte.
How long can a string be in a column in Oracle?
If you try to insert a value that is too long for the column, then Oracle returns an error. The default length for a CHAR column is 1 byte and the maximum allowed is 2000 bytes. A 1-byte string can be inserted into a CHAR (10) column, but the string is blank-padded to 10 bytes before it is stored.
