pl sql to number

The counting method of querying a field type from pl/SQL is number and the length is greater than 16 bits is displayed as scientific notation pl/SQL query field type from pl/SQL is

Problem Description:Oracle uses PL/SQL developer to export data to CSV format, VARCHAR2 Type field if the value (for example, 3307830000004059) is too long, the CSV file is represented in scientific notation, even if the column is selected, click Data--. > columns, fixed width, column data format select text, and the last one will still be set to 0.Workaround:Oracle uses

ABS (x) function, which is used to return the absolute value of a number.ACOS (x) function returns the arc cosine of X. X ranges from 1 to-1, and the input value ranges from 0 to pie, in radians.The ASIN (x) function returns the arc sine of X. X ranges from 1 to-1. The input value ranges from-PI/2 to PI/2, in radians.The ATAN (x) function returns the arc tangent of X. The input value ranges from-PI/2 to PI/2 in radians.BITAND (x, y) function returns the result of X and Y. X and Y must be non-neg

) function returns the hyperbolic sine of x. The SQRT (x) function returns the square root of x. x cannot be a negative number. The TAN (x) function returns the tangent of x. X is an angle in radians. The TANH (x) function returns the hyperbolic tangent of x. TRUNC (x [, y]) truncates the value function. The default value of Y is 0, so that X is truncated into an integer. If Y is negative, it is truncated to the right of the decimal point. WIDTH_BUCKE

the hyperbolic sine of x. SQRT (x) function that returns the square root of x and x cannot be negative. The TAN (x) function, which returns the tangent of x. X is the angle expressed in radians. TANH (x) function that returns the hyperbolic tangent of X. TRUNC (X[,y]) intercepts the value function, and the Y defaults to 0, so that X is truncated to an integer. If Y is a negative number, intercept to the appropriate position to the left of the decimal

1. First talk about the difference between pl/SQL and SQL * plus. For example, it is easy to understand: Pl/SQL-> C ++ LanguageSQL * plus-> Microsoft Visual C ++ 6.0 Compiler Pl/SQL is

This article gives you all the information you need in order to begin working with numbers in your PL/SQL programs.Numbers in PL/SQL PL/SQL offers a variety of numeric datatypes to suit different purposes:

The only drawback is that it can only be used for PL/SQL but
