How do I convert a character variable to a date in SAS?
Dates are the number of days since 1/1/1960. If you want to interpret it as date then use a PUT() statement to convert it the a character string and use INPUT() statement to convert it to a date. If you want to store the date value you have created into a character variable then use a PUT() statement.
Is date a character in SAS?
A SAS date isn’t a “standard” numeric or character variable – when displayed it can look like character data but is stored as a number. The date of January 1, 1960, has a value of zero (0) – prior dates are negative numbers, those after have positive values.
What does %eval do in SAS?
The %EVAL function evaluates integer arithmetic or logical expressions. %EVAL operates by converting its argument from a character value to a numeric or logical expression. Then, it performs the evaluation. Finally, %EVAL converts the result back to a character value and returns that value.
What is the difference between %eval and %Sysevalf functions?
The %EVAL function evaluates expressions using integer arithmetic. The %SYSEVALF function evaluates expressions using floating point arithmetic. Macro expressions are constructed with the same arithmetic and comparison operators found in the SAS language.
How do I convert character to SAS?
To convert numeric values to character, use the PUT function: new_variable = put(original_variable, format.); The format tells SAS what format to apply to the value in the original variable.
Can I convert character date to year/month in SAS EG?
I’m pretty new to SAS EG 8.3 and I’m trying to convert character date (ex. 20210111) to show as Year/Month (ex. 2021/01) but cant get it right. Yes, this can be done in the query builder.
Why is SAS treating my data as MMDDYY instead of anydate?
National language settings determine how SAS will interpret character values for use in Input function or informat treatment when the dates are ambiguous such as 01/11/2021 and the Informat used is one of the ANYDate versions. The default is apparently treating your data as MMDDYY so you need to take control and use a DDMMYY informat where needed.
What happens when%Eval encounters a value containing a period?
When %EVAL encounters a value containing a period, it displays an error message about finding a character operand where a numeric operand is required. An expression that compares character values in the %EVAL function uses the sort sequence of the operating environment for the comparison.
What types of arithmetic expressions does%% Eval accept?
%EVAL accepts only operands in arithmetic expressions that represent integers (in standard or hexadecimal form). Operands that contain a period character cause an error when they are part of an integer arithmetic expression. The following examples show correct and incorrect usage, respectively:
