2.Mergeis for adding new variables from a second dataset to existing observations. You use merge, for instance, when combining hospital patient and discharge datasets. If you wish to add new observations to existing variables, then see [D] append. You use append, for instance, when adding cu...
Stata can also join observations from two datasets into one;see[D]merge.See[U]23Combining datasets for a comparison of append,merge,and joinby.Quick start Append mydata2.dta to mydata1.dta with no data in memory append using mydata1mydata2 Same as above,but with mydata1.dta in memory...
Is there a problem with over-long variable names? Stata only allows variable names up to 32 characters long. If you have very long group and/or field names, the first 32 characters could fail to uniquely identify a variable. If you run into this problem, you're using SurveyCTO Desktop ...

By default, defv uses the same naming system as Stata's note command, so that the definitions it stores appear to have been created with note. (see [R] notes.) An advantage of this style is that variable definitions will be treated in the same way as other notes; for example, they ...
