If 'Pos' is not within the length range of the string, what will be the result in the function INSERT(str, Pos, len, newstr)?
Article Introduction：The MySQLINSERT() function does not perform the insertion operation when the insertion position is not within the string length range. There are some cases, like when we pass a negative value or 0 (zero) value, or when the value is more than 2 values of the total number of characters in the original string, we can say that 'pos' is not within the string length. It can be understood through the following example: The query below the example will not perform the insertion operation because 'pos' is not within the string length range, that is, it is a negative value. mysql>SelectINSERT('Tutorialspoint',-1,4,'.com');+----------

What is the length of number in oracle
Article Introduction：The Oracle NUMBER data type has a maximum length of 38 bits, including the decimal point and decimal places: 38 bits for the integer part and 128 bits for the fractional part. Precision is the number of digits that can be stored after the decimal point and ranges from 0 to 128. When choosing the appropriate length, consider data range, accuracy requirements, and storage space.

What is the range of representation of floating point numbers?
Article Introduction：The representation range of floating-point numbers: 1. For single-precision floating-point numbers, the representation range is approximately ±3.4 × 10^38, which can also be expressed as ±3.4E+38 in scientific notation; 2. For double-precision floating-point numbers, the representation range is wider, approximately ±1.8 × 10^308, or ±1.8E+308 in scientific notation.

php exceeds the shaping range
Article Introduction：Most programming languages have limits on variable types. Exceeding these limits will cause running problems or errors, and PHP is no exception. In PHP, the range of integer variables is -2147483648 to 2147483647. When this range is exceeded, the problem of exceeding the integer range will occur. There may be many reasons for exceeding the range of the integer type, such as: 1. Number operations exceed the range. When adding two integers, if their sum exceeds the maximum value of the integer type, an out-of-range problem will result. 2. Integer overflow problem. Another value beyond the range of an integer

Computer networks can be divided into what types according to the scope of their coverage
Article Introduction：Computer networks can be divided according to their coverage range: 1. Local area network, which can be used in a small area, and the coverage is usually limited to 10 kilometers; 2. Metropolitan area network, whose scope is between the wide area network and the local area network. The coverage can usually extend to the entire city; 3. Wide area network, a long-distance network, involves long-distance communication, and the coverage can be a country or multiple countries, or even the entire world.
